Lease-wide average
Apply one explicit concession to a positive lease term and compare the stated monthly rent with the resulting net lease total and effective monthly average.
Advertised rent stays visible
Choose one explicit concession type: whole rent-free months or one fixed credit.
Only one concession type is applied. This tool does not create payment schedules, combine promotions, or determine accounting, tax, or lease treatment.
Lease-wide average
Stated rent, concession value, net lease total, and effective average remain separate.
$24,000.00 gross lease total − $2,000.00 concession = $22,000.00 net lease total; $22,000.00 ÷ 12 months = $1,833.33 effective monthly rent
The advertised or stated rent remains $2,000.00 per month for 12 months. The explicit concession is 1 rent-free month, valued at $2,000.00. The net lease total is $22,000.00, and the effective monthly average rounds to $1,833.33. This calculator does not create a payment schedule or determine lease, accounting, tax, or legal treatment.

Example: $2,000 stated rent over 12 months produces a $24,000 gross lease total. One rent-free month is a $2,000 concession, leaving a $22,000 net lease total and a rounded effective average of $1,833.33 per month.
RentSplit supports the smallest explicit shapes needed for common calculations: whole rent-free months or one fixed amount. Rent-free months must be a non-negative integer no greater than the lease term. A fixed amount must be non-negative, whole-cent representable, and no greater than the gross lease total.
Multiple promotions, percentage discounts, staged credits, recurring partial-month discounts, and conditional offers remain outside this calculator.
Start with the stated monthly rent and the complete lease term. Those two inputs define the gross lease total before any concession. Then identify whether the offer is expressed as whole rent-free months or as one fixed dollar credit. Enter only the concession that is clearly stated and do not combine both modes in one calculation.
Promotional language such as “one month free,” “$2,000 credit,” or “net effective rent” may describe different payment arrangements. This calculator normalizes the entered concession into one lease-wide value, subtracts it from the gross total, and divides the net total across the lease term. It does not determine when the credit appears on a ledger.
With $2,400 stated monthly rent and a 12-month lease, the gross lease total is $28,800. One free month is worth $2,400, so the net lease total is $26,400. Dividing $26,400 by 12 produces an effective monthly average of $2,200.
With the same $2,400 rent and 12-month term, a fixed $1,800 concession produces a $27,000 net lease total and a $2,250 effective monthly average. The fixed credit is smaller than one full month, so its effective average is higher than the one-month-free example.
At $3,000 per month for 18 months, gross rent is $54,000. Two free months are worth $6,000, leaving $48,000 net rent. The lease-wide effective monthly average is $2,666.67 after rounding to the nearest cent.
These examples compare concession value over the complete term. They do not state what is due in a particular month. A property may apply a credit at the beginning, spread it across payments, or require repayment after an early move-out; those timing and condition questions must be read from the offer or lease.
Stated monthly rent is the recurring amount before the entered promotion. Effective monthly rent is a calculated average after spreading the concession across the full term. A scheduled monthly payment is the amount actually due on a particular date. Those three figures can be different even when the arithmetic is accurate.
For example, an apartment may advertise a lower net-effective figure while the lease still lists a higher stated rent for most months and applies one credit separately. Comparing listings by effective average can be useful, but budgeting requires the actual payment schedule, deposits, fees, and any conditions attached to the promotion.
RentSplit displays stated and effective amounts side by side so the concession is not mistaken for a permanent change to the contractual rent. The tool does not rewrite an advertised figure, decide which number a listing should feature, or represent a lease payment ledger.
A lower effective rent does not automatically include application fees, security deposits, amenity fees, parking, storage, pet charges, utilities, renter's insurance, moving costs, or renewal pricing. Those amounts can materially change a housing comparison but are not rent concessions under this focused formula.
Conditional offers also need separate review. A concession may depend on signing by a deadline, completing the lease term, using a required payment method, or remaining in good standing. Some agreements describe repayment or loss of the credit after an early termination. The calculator does not interpret, validate, or enforce those conditions.
To compare two offers, calculate each lease with its own stated rent, term, and explicit concession, then list all excluded costs and timing conditions beside the effective average. That keeps the mathematical comparison useful without presenting it as accounting, financial, or legal advice.
The effective amount is a mathematical average across the lease term. It does not say which month is free, change the stated rent, create a ledger, model deposits or fees, decide accounting or tax treatment, or interpret the enforceability of an offer.
It accepts either a non-negative whole number of rent-free months or one non-negative fixed concession amount. The calculator applies only one type at a time.
It is the net lease total after the explicit concession divided by the positive integer lease term, rounded to the nearest whole cent.
No. The stated monthly rent remains a separate advertised or contractual input. Effective monthly rent is a lease-wide average after the entered concession.
No. Rent-free months cannot exceed the lease term, and a fixed concession cannot exceed the gross lease total.
No. It does not allocate discounts to particular payments, model accounting or taxes, amortize amounts, or interpret lease terms.
