Calculation
Not calculated
Current rent + (Current rent × Renewal %) + Fixed increase = New rent
Disclaimer: This calculator is provided for general informational purposes only. Verify lease terms, notice requirements, local rent regulations, and all figures before proposing or accepting a renewal.
How it's calculated
New rent = current rent + (current rent × renewal percentage) + fixed increase
The percentage increase is rounded to the nearest cent (half a cent rounds up) before it's added. The fixed increase is a flat dollar amount added on top, and the percentage isn't applied to it.
Example: 3% plus $25
Current rent is $1,800, the renewal percentage is 3%, and the fixed increase is $25.
- 3% of $1,800 = $54.00
- Total increase: $54.00 + $25.00 = $79.00
- New rent: $1,800.00 + $79.00 = $1,879.00
The effective increase is the total increase as a share of current rent: $79 ÷ $1,800 = 4.39%. Use it to check the full increase against a percentage limit, such as a cap in the lease or local rules.
Common questions
Can I use only a percentage or only a flat increase?
Yes. Leave the other field blank and it counts as zero.
Why is the effective increase higher than the renewal percentage?
It includes the fixed increase. If current rent is $0, there's nothing to compare against, so it shows "Not applicable."
Can I calculate a rent decrease?
No. This calculator only handles increases. To find the change between two rents in either direction, use the Rent Comparison Calculator.
Does this tell me how much I can raise the rent?
No. Some states and cities limit rent increases or require advance written notice. Check the lease and local rules before you send a renewal offer.
