Commercial Real Estate Leasing Metrics: The Complete Guide

Commercial real estate leasing metrics help owners, asset managers, leasing teams, brokers, property managers, and analysts understand whether a property is attracting tenants, retaining tenants, converting vacant space into income, and protecting future cash flow.

A property can look healthy today while still carrying major leasing risk underneath the surface. A large lease expiration, weak renewal activity, slow leasing velocity, long downtime, declining rent spreads, or a thin leasing pipeline can all create future pressure on occupancy, NOI, cash flow, and property value.

The best leasing operators do not only track signed leases after the fact. They monitor lease expirations, renewals, tenant retention, available space, deal velocity, rent economics, downtime, pipeline quality, and rollover risk before those issues fully appear in the financial statements.

This guide is the starting point for the CRE Wisdoms commercial real estate leasing metrics cluster. Each section below introduces a major leasing KPI and links naturally to a deeper page where that metric can be explained in more detail.

What Are Commercial Real Estate Leasing Metrics?

Commercial real estate leasing metrics are key performance indicators used to measure leasing activity, tenant demand, renewal risk, lease economics, available space, lease expiration exposure, and the health of the leasing pipeline. They help operators understand how space moves from vacant or at-risk status into signed, income-producing leases.

These metrics are especially important because leasing activity often changes before property income changes. A rent roll may look stable today, but if a large percentage of leases expire in the next twelve months, the property may already have future income at risk. Likewise, current NOI may look strong while the leasing pipeline is too weak to replace upcoming move-outs.

That is why leasing metrics need to be viewed as a connected system. Lease expirations create rollover risk. Renewal activity affects tenant retention. Downtime affects vacancy loss. Rent spreads affect future revenue. Leasing velocity affects how quickly vacant space becomes income. One number rarely tells the full story.

Why Leasing Metrics Matter in Commercial Real Estate

Commercial real estate value depends heavily on the quality, durability, and timing of rental income. Leasing metrics help explain whether that income is stable, growing, weakening, or exposed to future risk.

Good leasing metrics help operators answer practical questions. How much space is expiring? Are tenants renewing or leaving? How long does space sit vacant before it is re-leased? Are new leases being signed above or below prior rent? Is the leasing pipeline strong enough to protect future occupancy? Are tenant improvements and leasing commissions reducing the economics of new deals?

For owners and asset managers, leasing metrics connect directly to NOI and valuation. A property with strong tenant retention, manageable rollover, healthy rent spreads, and limited downtime is usually more durable than a property that depends on constant replacement leasing to protect income.

Core Commercial Real Estate Leasing Metrics Every Operator Should Understand

Leasing performance is shaped by a connected set of renewal, rollover, vacancy, pipeline, rent, and tenant-retention metrics. Each KPI below explains a different part of the leasing story, but the real value comes from reading them together.

A property with strong current occupancy, weak renewals, heavy upcoming expirations, and slow leasing velocity is telling a very different story than one with durable tenant retention, limited rollover exposure, healthy rent spreads, and a strong pipeline of signed leases.

WAULT

WAULT, or weighted average unexpired lease term, measures the average remaining lease term across a property or portfolio, weighted by rent, income, or square footage. It helps operators understand how durable the current lease income may be.

A longer WAULT usually suggests more income stability, while a shorter WAULT may indicate more near-term rollover risk. However, WAULT should not be viewed by itself. A long WAULT with weak tenants may be less attractive than a shorter WAULT with strong tenants and healthy renewal probability.

The core CRE Wisdoms page on WAULT in commercial real estate explains how weighted lease term helps measure income durability, rollover exposure, and lease-risk concentration.

WALT vs WAULT

WALT and WAULT are closely related, but they are not always used the same way. WALT usually refers to weighted average lease term, while WAULT often emphasizes the unexpired portion of the lease term remaining.

The distinction matters because lease-term metrics can be calculated and interpreted differently depending on whether the operator is analyzing original lease term, remaining term, income weighting, square footage weighting, or tenant-risk exposure.

The comparison page on WALT vs WAULT explains how these lease-term metrics differ and why definitions matter when evaluating income durability.

Lease Expiration Schedule

A lease expiration schedule shows when leases expire across a property or portfolio. It helps operators understand how much space, rent, and tenant income may be at risk in each future period.

This is one of the most important commercial real estate leasing metrics because a property can be stable today but exposed tomorrow. If too many leases expire in the same year, the owner may face rollover risk, downtime, leasing costs, tenant improvement costs, and potential NOI pressure.

Lease expiration analysis is where leasing risk often begins. The dedicated page on lease expiration schedule in commercial real estate will explain how operators use expiration timing to identify future occupancy and income risk.

Lease Rollover

Lease rollover measures the amount of space, rent, or income scheduled to expire and potentially roll over during a given period. It is closely related to the lease expiration schedule but focuses more directly on the risk of renewing, replacing, or re-pricing tenants.

High rollover is not automatically bad, but it does require attention. It may create an opportunity to mark rents to market, reposition space, or upgrade tenant mix. It may also create vacancy risk, downtime, leasing commissions, tenant improvement costs, and income uncertainty.

Rollover is where future income becomes exposed to leasing execution. The deeper article on lease rollover in commercial real estate explains how rollover risk affects leasing strategy, NOI durability, cash flow planning, and asset management decisions.

Renewal Rate

Renewal rate measures the percentage of expiring tenants that renew their leases instead of leaving. It is one of the clearest measures of tenant retention and property stability.

A strong renewal rate can protect occupancy, reduce downtime, lower leasing costs, and support more predictable income. A weak renewal rate may signal tenant dissatisfaction, market competition, poor property positioning, rent pressure, or broader demand weakness.

Tenant retention often starts with renewal performance. The page on commercial lease renewal rate will explain how renewal activity affects occupancy, leasing costs, rent roll stability, and NOI.

Tenant Retention Rate

Tenant retention rate measures how effectively a property keeps tenants over time. While renewal rate focuses on expiring leases, tenant retention can be viewed more broadly as a measure of relationship durability, income stability, and long-term occupancy strength.

Retention matters because replacing commercial tenants is often expensive. A lost tenant can create downtime, build-out costs, leasing commissions, legal costs, rent concessions, and operating disruption. In many cases, retaining a strong tenant is more valuable than replacing that tenant at a theoretically higher rent.

Tenant retention is about the durability of the tenant base, not just one renewal event. The guide to tenant retention rate in commercial real estate explains why strong tenant relationships can protect occupancy, NOI, cash flow, and asset value.

New Leasing Volume

New leasing volume measures how much new space has been leased during a given period. It helps operators understand whether leasing activity is strong enough to fill vacancy, replace move-outs, and support occupancy recovery.

New leasing volume should be compared against expirations, move-outs, available space, renewals, and signed leases not yet commenced. A property can sign new leases and still lose ground if expirations or move-outs are happening faster than new leasing activity.

New leasing volume is where tenant demand becomes signed commitment. The dedicated page on new leasing volume in commercial real estate explains how new lease activity fits into occupancy, absorption, pipeline analysis, NOI, cash flow, and asset value.

Net Absorption

Net absorption measures the net change in occupied space over a period. In simple terms, it shows whether more space became occupied or vacant after move-ins, move-outs, expansions, and contractions are considered.

Positive net absorption usually means occupied space increased. Negative net absorption usually means occupied space declined. This metric helps operators understand whether leasing activity is actually improving occupancy or merely replacing lost tenants.

Net absorption is where leasing activity becomes occupancy movement. The guide to net absorption in commercial real estate explains how tenant move-ins, move-outs, expansions, and contractions affect occupied space, NOI, cash flow, and property value.

Rent Spread

Rent spread measures the difference between new or renewal lease rent and the prior rent for the same space. It helps operators understand whether leasing activity is increasing or decreasing rental income.

A positive rent spread may suggest pricing power or market rent growth. A negative rent spread may indicate weaker demand, tenant leverage, market softness, or the need to retain occupancy at lower economics. The spread should always be reviewed alongside concessions, tenant improvements, leasing commissions, downtime, and net effective rent.

Rent spread is where leasing activity turns into rent movement. The page on rent spread in commercial real estate explains how new and renewal leasing affects future rental income, NOI, cash flow, and property value.

Leasing Velocity

Leasing velocity measures how quickly available space is being leased. It helps operators understand whether leasing activity is moving fast enough to protect occupancy, reduce downtime, and support future income.

Leasing velocity should be interpreted with rent economics. Fast leasing is not automatically good if the property is discounting heavily, offering large concessions, or accepting weak tenants. Slow leasing is not automatically bad if the property is protecting rent quality and negotiating stronger long-term deals.

Leasing velocity is where leasing activity gets measured against time. The velocity-focused guide on leasing velocity in commercial real estate explains how leasing speed affects occupancy recovery, downtime, revenue timing, NOI, cash flow, and asset value.

Available Space

Available space measures the square footage that is currently vacant, expected to become vacant, or otherwise available for lease. It is one of the basic building blocks of leasing analysis because it shows what inventory the leasing team needs to fill.

Available space should be reviewed by size, location, condition, readiness, asking rent, lease status, and target tenant type. A small amount of highly marketable available space is different from a large block of space that is outdated, poorly configured, or not aligned with current tenant demand.

Available space defines the leasing challenge. The inventory-focused page on available space in commercial real estate explains how operators evaluate what can actually be leased, how future availability affects risk, and how available inventory connects to leasing velocity, vacancy loss, NOI, and asset value.

Downtime

Downtime measures the time between one tenant leaving and the next tenant beginning occupancy or rent payments. It is one of the most important leasing metrics because vacant time directly affects income.

Long downtime can reduce NOI, weaken cash flow, and increase pressure on asset value. It may also signal issues with pricing, space condition, tenant demand, leasing execution, build-out requirements, or market positioning.

Downtime is the cost of time without rent. The page on downtime in commercial real estate explains how vacant periods affect revenue, leasing strategy, NOI, cash flow, and property value.

Vacancy Loss

Vacancy loss measures the rental income lost because space is vacant and not producing rent. While vacancy rate measures empty space, vacancy loss translates that vacancy into lost income.

This distinction matters because not all vacant space has the same financial impact. A vacant anchor box, office floor, medical suite, or high-rent retail space can create a much larger income loss than a smaller, lower-rent space.

Vacancy loss is where empty space becomes a financial problem. The page on vacancy loss in commercial real estate explains how vacant space affects rental income, NOI, cash flow, and asset value.

Proposal-to-Lease Conversion Rate

Proposal-to-lease conversion rate measures how many leasing proposals eventually become signed leases. It helps operators understand whether tenant interest is moving from discussion to commitment.

A weak conversion rate may signal pricing issues, poor deal terms, slow follow-up, tenant credit concerns, competitive weakness, space-condition problems, or a mismatch between prospects and available space. Strong proposal activity is useful only if it moves through the pipeline and becomes executable lease income.

Proposal conversion is where leasing pipeline activity gets tested. The page on proposal-to-lease conversion rate explains how operators evaluate the quality and effectiveness of their deal pipeline before it affects vacancy, NOI, cash flow, and asset value.

LOI Pipeline

The LOI pipeline measures leasing activity that has reached the letter-of-intent stage but has not yet become a signed lease. It helps operators understand future leasing momentum and possible occupancy recovery.

A strong LOI pipeline can be encouraging, but it is not the same as signed income. LOIs can stall, be renegotiated, or fall apart before lease execution. Operators should evaluate pipeline probability, deal quality, timing, tenant credit, expected commencement dates, and net effective economics.

The LOI pipeline is where serious leasing interest starts to look real, but it is still not guaranteed income. The page on LOI pipeline in commercial real estate explains how letters of intent help forecast future leasing outcomes without overstating certainty.

Signed Leases Not Yet Commenced

Signed leases not yet commenced are leases that have been executed but have not yet started producing occupancy or rent. These leases are important because they represent future income that may not yet appear in current occupancy, NOI, or cash flow.

This metric helps operators bridge the gap between current performance and near-term future performance. A property may look vacant today but have signed leases scheduled to commence soon. Another property may look stable today but have limited future signed activity.

Signed leases are stronger than LOIs, but they are still not the same as current income. The page on signed leases not yet commenced explains how executed future leases affect occupancy forecasting, rent commencement timing, NOI, cash flow, and asset management reporting.

Tenant Improvement Allowance

Tenant improvement allowance, often called TI allowance, measures the landlord contribution toward building out or improving leased space for a tenant. It is a major economic component of many commercial leases.

TI allowances matter because a lease with strong face rent may still have weaker economics if the landlord must spend heavily to secure the tenant. Leasing performance should be evaluated after considering rent, term, downtime, concessions, leasing commissions, and tenant improvement costs.

Tenant improvement allowance is the capital cost of creating or preserving rent. The page on tenant improvement allowance in commercial real estate explains how TI costs affect deal economics, lease timing, cash flow, NOI, and property value.

Leasing Commissions

Leasing commissions are payments made to brokers or leasing agents for completing lease transactions. They are an important cost of leasing activity and can materially affect the economics of new and renewal deals.

High leasing commissions may be justified when they secure strong tenants, long terms, and durable income. But commissions still need to be evaluated as part of the total cost of creating or preserving occupancy.

The leasing-cost page on leasing commissions in commercial real estate will explain how commissions affect lease economics, cash flow, and investment performance.

Net Effective Rent

Net effective rent measures the true economics of a lease after concessions, free rent, tenant improvements, leasing commissions, downtime, and other deal costs are considered. It gives operators a cleaner view of what the landlord is really earning from a lease.

This metric is especially important because face rent can be misleading. A lease may look strong based on rent alone, but the economics may weaken after free rent, TI allowances, commissions, and downtime are included.

Net effective rent is where the real lease economics come into focus. The page on net effective rent in commercial real estate explains how operators evaluate the true value of new leases, renewals, and replacement deals.

Occupancy Cost

Occupancy cost measures how much a retail tenant pays to occupy its space compared with the sales generated from that location. It usually includes base rent, CAM, real estate taxes, insurance, percentage rent, utilities, and other occupancy-related charges.

This is one of the most important retail real estate metrics because it helps operators understand whether the tenant’s rent burden is sustainable. A tenant with strong sales and reasonable occupancy cost may be more likely to renew, accept rent growth, and remain financially healthy. A tenant with weak sales and high occupancy cost may become a renewal risk, rent relief candidate, or future vacancy problem.

Occupancy cost connects tenant sales to leasing strategy. The page on occupancy cost in commercial real estate explains how rent burden affects tenant health, percentage rent, renewal risk, tenant retention, NOI, and retail asset value.

Sales per Square Foot

Sales per square foot measures how much revenue a retail tenant generates relative to the size of its leased space. It is one of the most important tenant productivity metrics in retail leasing because it helps operators understand whether a location is producing enough sales to support the rent and total occupancy cost.

This metric matters in leasing because tenant sales productivity affects renewal risk, rent spread potential, percentage rent, tenant retention, and replacement leasing assumptions. A tenant with strong sales per square foot may be able to support rent growth, while a tenant with weak or declining sales productivity may become a renewal risk or future vacancy problem.

Sales per square foot connects retail performance to leasing strategy. The page on sales per square foot in commercial real estate explains how tenant sales productivity affects occupancy cost, percentage rent, renewals, NOI, cash flow, and retail property value.

Percentage Rent

Percentage rent is additional rent based on a tenant’s sales above a negotiated breakpoint. It is most commonly used in retail leases and allows the landlord to participate in tenant sales upside when the location performs well.

This metric matters in both leasing and retail performance analysis because it connects lease structure directly to tenant sales. Percentage rent can affect renewal strategy, rent negotiations, occupancy cost, sales reporting, tenant retention, NOI, and long-term retail asset value.

Percentage rent is where tenant sales become potential landlord upside. The page on percentage rent in commercial real estate explains how sales-based rent structures work and why they matter for leasing strategy, retail performance, and property income.

Why Leasing Metrics Should Be Viewed Together

The mistake many people make is treating leasing metrics as separate numbers. In reality, they are connected. Lease expirations create rollover risk. Rollover affects renewal strategy. Renewals affect downtime. Downtime affects vacancy loss. Rent spreads affect future income. TI allowances, concessions, and leasing commissions affect the true economics of signed deals.

For example, a property may show strong new leasing volume, but if rent spreads are negative and TI allowances are high, the deal economics may be weaker than the activity level suggests. Another property may show modest leasing volume, but strong renewals, limited downtime, and healthy rent spreads may indicate better income durability.

That is why CRE Wisdoms treats commercial real estate leasing metrics as an operating system, not a glossary. The goal is not just to define each KPI. The goal is to explain how the numbers work together and what they reveal about future property performance.

Commercial Leasing Metrics and NOI

Most commercial leasing metrics eventually connect back to NOI. New leases add income. Renewals preserve income. Rent spreads affect revenue growth. Downtime reduces income. Leasing commissions, concessions, and tenant improvements affect the economics of creating or preserving occupancy.

That does not mean NOI tells the whole leasing story by itself. NOI is often a lagging result. Leasing metrics can show risk before it appears in the income statement. A major expiration next year, a weak renewal pipeline, or a slow leasing market may not fully affect current NOI yet, but it may already be changing the property’s future income profile.

For that reason, operators should use NOI as a major performance measure while also watching the leasing indicators behind it. The core CRE Wisdoms page on net operating income explains how income and expenses combine to shape property value.

Commercial Leasing Metrics and Asset Value

Commercial real estate value depends heavily on the durability of the income stream. A property with long-term leases, strong tenants, manageable rollover, healthy renewals, limited downtime, and disciplined deal economics is usually more durable than a property with short lease terms, high rollover, weak tenant retention, and expensive replacement leasing.

Leasing metrics help investors and operators separate current income from durable income. That distinction matters because valuation is not just about the rent a property reports today. It is also about how reliable that income is likely to be in the future.

This is where leasing metrics become investment metrics. Lease term, rollover exposure, tenant retention, downtime, rent spreads, tenant credit, and deal economics all help explain whether the income stream is strong, fragile, or somewhere in between.
