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.

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.
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.
