About Rent Increase Calculator
The Rent Increase Calculator applies a percentage increase to the current rent and shows both the new rent and the dollar amount of the monthly increase. From the current rent and the increase percentage, it raises the rent by that percentage and reports the resulting figure alongside the change.
Whether you are a landlord planning a renewal or a tenant checking a proposed rise, seeing the new rent and the exact monthly increase side by side makes the impact concrete. The tool reflects only the current rent and percentage you enter, with no market data or caps applied.
Enter the current rent and the increase percentage, press Calculate, and read the new rent and the monthly increase in dollars.
Formula & Mathematical Calculation
New Rent = Current Rent × ( 1 + Increase % ÷ 100 )
Monthly Increase = New Rent − Current Rent
Calculation Example
Raising a $1,500 rent by 5% gives a new rent of $1,500 × 1.05 = $1,575, a monthly increase of $1,575 − $1,500 = $75.
Key Benefits
- Applies any percentage increase to the current rent and returns the new figure.
- Shows the dollar amount of the monthly increase, not just the new rent.
- Works for both renewal planning and checking a proposed increase.
- Uses only the current rent and percentage you enter, applying no caps or market data.

Press Calculate
