Average effective rent is the mean rent collected per unit across a property or portfolio after concessions, free rent, and discounts are subtracted from the face rate and spread over the lease term. It measures the rent a property actually earns, not the rate it advertises, and it is the revenue figure underwriting relies on.
What Is Average Effective Rent in Multifamily?
Average effective rent is the average net rent per unit a multifamily property collects once concessions are netted out of the asking rate and spread across the lease term. It converts a marketing number into a revenue number. Where asking rent is what a landlord requests, average effective rent is what the rent roll actually produces after incentives.
Concessions are large enough in 2026 that the gap is material. Per RealPage Analytics, the average US apartment concession reached 10.9% in May 2026, equal to nearly six weeks of free rent on a 12-month lease. That discount does not appear in the asking rate. It shows up only when free rent is spread across the term, which is exactly what average effective rent captures and asking rent hides.
Term | What it measures |
Asking rent | Advertised rate per unit, before any concession |
Face rent | Contract rate on the signed lease, before concessions |
Effective rent | One unit's rate net of concessions over the term |
Average effective rent | Mean of effective rents across all units |
Average effective rent is the portfolio-level figure. It rolls up each unit's effective rent into one property or submarket average, which is why it is the number that appears in analytics feeds and appraisals as the true measure of achieved rent.
How Is Average Effective Rent Calculated?
Average effective rent is calculated in two steps. First, compute each unit's effective rent by subtracting the total concession value from the total face rent over the lease term, then dividing by the lease months. Second, average those per-unit effective rents across all units in the property or sample to get the property-level figure.
The per-unit formula is: effective rent = (face rent x lease months minus total concession value) divided by lease months. A unit at $2,000 per month on a 12-month lease with one month free collects $22,000 over the year, or $1,833 per month effective. The one free month is not a one-time event in this math. It is spread evenly, lowering every month's recognized rent.
Input | Value |
Face rent | $2,000 per month |
Lease term | 12 months |
Concession | 1 month free ($2,000) |
Total collected | $22,000 |
Effective rent | $1,833 per month |
Averaging then weights each unit equally, or by square footage if the sample mixes unit types. The result is one rate that reflects both the advertised price and the incentive load, which is why average effective rent, not asking rent, feeds economic occupancy and NOI models.
Why Average Effective Rent Matters
Average effective rent matters because it is the only rent figure that ties directly to collected revenue, and therefore to value. An underwriter who models asking rent instead of average effective rent overstates income by the full concession load, which in 2026 can approach 11% of face rent per RealPage. That error compounds through NOI and, at a fixed cap rate, into valuation.
The discipline is to underwrite achieved rent, not advertised rent. When a submarket's average effective rent falls while asking rent holds flat, the market is softening through concessions rather than headline cuts, a pattern that a landlord holding asking rents steady can mask for months. Average effective rent surfaces that erosion early, which is why asset managers track the asking-to-effective spread as a demand signal, not just a revenue figure.
Example
A 100-unit property advertises an average asking rent of $2,000 per unit. To fill vacancy, the operator grants six weeks of free rent on new 12-month leases, and 40 of the 100 units are new signings this year carrying that concession. The remaining 60 units renewed at face rate with no concession. The table works the blended average effective rent.
Unit group | Units | Face rent | Concession | Effective rent |
New leases | 40 | $2,000 | 6 weeks free (1.5 mo) | $1,750 |
Renewals | 60 | $2,000 | None | $2,000 |
Blended | 100 | $2,000 | Weighted | $1,900 |
New-lease math: 6 weeks is 1.5 months, so the unit collects $2,000 x 10.5 over 12 months, equal to $21,000, or $1,750 per month effective. Blended average effective rent is (40 x $1,750 plus 60 x $2,000) divided by 100, which equals $1,900. The property advertises $2,000 but earns $1,900, a 5.0% gap that removes $120,000 of annual gross rent (100 x $100 x 12) before a single vacant day is counted.
Variations and Edge Cases
Average effective rent shifts with how concessions and unit mixes are treated, so two properties quoting the same asking rent can report different effective averages. The table below lists the adjustments an analyst should confirm before comparing two figures.
Variant | Treatment |
Amortized vs upfront concession | Free rent spread over the term versus taken in month one changes monthly effective rent, not annual |
Renewal vs new-lease blend | New leases usually carry deeper concessions, so a high renewal share lifts the average |
Weighted vs simple average | Weighting by square footage or unit count corrects for skewed unit mixes |
Trade-outs excluded | Some feeds report effective rent on new leases only, understating a stabilized property |
Gross vs net concession | Deducting only rent concessions, not fees waived, understates the true incentive load |
The most common error is averaging asking rents and calling the result effective rent. Average effective rent requires netting concessions at the unit level first, then averaging. Reversing the order, or skipping the netting entirely, reproduces the asking-rent overstatement the metric exists to remove.
Average Effective Rent vs Asking Rent
Average effective rent is often confused with asking rent, and the difference decides whether a pro forma holds. Asking rent is the advertised rate a property requests per unit, before any concession. Average effective rent is the mean rate the property actually collects after free rent and discounts are netted out and spread over the lease term. One is a marketing number, the other is a revenue number.
Asking rent almost always sits above average effective rent, and the spread is the concession load. In a soft market a landlord holds asking rent flat and competes on free rent, so asking rent can look stable while average effective rent falls. Analysts read that widening spread as demand weakness. Per RealPage, the May 2026 national concession of 10.9% is the size of that gap on a newly signed lease, and it belongs in the underwriting model, not the headline.
Frequently Asked Questions
What is the difference between average effective rent and asking rent?Asking rent is the advertised rate a property requests per unit before any concession. Average effective rent is the mean rate the property actually collects after free rent and discounts are netted out and spread across the lease term. Asking rent overstates revenue by the concession load.
How do you calculate average effective rent?Compute each unit's effective rent by subtracting total concession value from total face rent over the lease term, then dividing by lease months. Average those per-unit figures across all units. A $2,000 unit with one month free on a 12-month lease has an effective rent of $1,833 per month.
Why is average effective rent lower than asking rent in 2026?Concessions are elevated. Per RealPage Analytics, the average US apartment concession was 10.9% in May 2026, roughly six weeks of free rent on a 12-month lease. That incentive lowers collected rent below the advertised asking rate, and average effective rent is the figure that captures the difference.
