How Net Effective Rent Calculation Works
Net effective rent is calculated using this formula:
Net Effective Rent Formula:
NER = (Total Rent - Concessions + Move-In Costs) ÷ Lease Months
Where:
Total Rent = Monthly rent × Lease term
Concessions = Free months + Discounts
Move-In Costs = Application, admin fees
Example Calculation
Advertised rent: $2,000/month
Lease term: 12 months
Concession: 1 month free
Total rent: $2,000 × 12 = $24,000
Less free month: -$2,000
Net effective: $22,000 ÷ 12 = $1,833.33/month
Key Rental Concepts Explained
Rent Concessions
Incentives landlords offer to attract tenants, including free months, reduced rent, waived fees, or other promotional benefits.
Free Months
Months where no rent is charged, typically spread throughout lease term (e.g., first month free or last month free).
Advertised Rent
The listed monthly rent amount before concessions. This is often higher than net effective rent when concessions apply.
Move-In Costs
Upfront fees including application fees, administrative fees, and other one-time charges that increase effective cost.

Factors That Affect Net Effective Rent
1. Number of Free Months
More free months = lower net effective rent. Two free months on a 12-month lease reduces effective rent by 16.67%.
2. Lease Length
Longer leases spread concessions over more months, increasing net effective rent. Shorter leases amplify concession value.
3. Upfront Fees
High move-in costs increase net effective rent. $1,000 in fees on 12-month lease adds $83.33 to monthly effective cost.
4. Timing of Concessions
When free months occur doesn't change net effective rent, but affects cash flow (first month free vs. last month free).
5. Market Conditions
Weak rental markets offer more concessions, lowering net effective rent. Strong markets have fewer concessions available.
Frequently Asked Questions
What is net effective rent?
Net effective rent is the true average monthly cost of renting after accounting for concessions like free months, rent discounts, and move-in specials. It's calculated by dividing the total rent paid over the lease term by the number of months, giving you the actual monthly cost.
How do you calculate net effective rent?
Calculate net effective rent by: (1) Multiply monthly rent by lease term, (2) Subtract all concessions (free months, discounts), (3) Add move-in costs, (4) Divide total by lease term months. For example: ($2,000 × 12 - $2,000 free month) ÷ 12 = $1,833.33 net effective rent.
Why is net effective rent important?
Net effective rent reveals the true rental cost, helping you compare apartments fairly. An apartment advertising $2,000/month with 2 free months ($1,667 net effective) is cheaper than one at $1,800/month with no concessions, even though the advertised rate is higher.
Do landlords have to honor advertised concessions?
Landlords must honor concessions advertised in writing and included in your lease agreement. Always get concessions documented in the lease. Verbal promises without written confirmation are not legally binding and may not be honored.
Are rent concessions taxable income?
For tenants, rent concessions are generally not taxable income. They're considered a reduction in rent expense. For landlords, concessions reduce rental income. Tax treatment varies by jurisdiction, so consult a tax professional for specific guidance.
