Rent Increase Calculator
See exactly what a rent hike will cost before you sign or negotiate. Enter your current monthly rent and the percentage raise, and the tool returns the new monthly rent, the extra dollars each month, and the total added over a full year. It runs entirely in your browser, so the figures you type are never sent anywhere.

- Pick your currency from the selector at the top right if you are not using US dollars.
- Type your current monthly rent in the Current monthly rent field.
- Enter the raise in the Increase field as a percentage, for example 5 for a 5 percent bump.
- For a rent reduction, enter a negative number such as -10.

Frequently asked questions
How do I calculate a rent increase percentage?
Multiply the current rent by the percentage divided by 100, then add it to the current rent. A 5 percent raise on 1,500 is 1,500 times 0.05, which is 75, giving a new rent of 1,575. The tool does this instantly as you type.
How much more will I pay over a year?
Multiply the monthly dollar increase by 12. A 75 per month increase costs 900 more over a full year, which the Yearly increase card shows for you, before any further changes to the lease.
Can I use this for a rent decrease?
Yes. Enter the change as a negative percentage such as -10. A negative value lowers the rent and reports the monthly and yearly figures as savings shown with a minus sign.
Is there a legal limit on how much rent can go up?
Limits vary by location. Some cities and states have rent control or rent stabilization caps, while many areas set no cap between leases. This tool does no legal check, so confirm your local rules and your lease terms.
Does the result include fees, parking or utilities?
No. The output covers only the base rent and the percentage you enter. Add any separate charges such as parking, pet rent or utilities yourself to see your true monthly total.
What if I know the new rent but not the percentage?
You can solve it in reverse: divide the new rent by the old rent, subtract 1, and multiply by 100. Going from 1,500 to 1,600 is 1,600 divided by 1,500 minus 1, which is about 6.67 percent.
Can I change the currency?
Yes. The selector at the top right switches the symbol and formatting used on the result cards. The math is identical for any currency since it is a simple percentage of the amount you enter.
Are my rent figures saved or uploaded?
No. Everything runs locally in your browser and nothing is stored or sent to a server, so you can test different raises privately without leaving a trace.
What other tools help with renting decisions?
Pair this with the rent-to-income ratio calculator to check affordability, the rent proration calculator for a partial first month, and the price-to-rent ratio calculator when weighing renting against buying.
