Rent Increase Calculator
Turn a rent hike into new monthly rent, percent increase, and extra cost per year. Enter a percent or a dollar increase for tenants and landlords.
How to use this rent increase calculator
Rent increase math is simple and easy to fumble when a notice quotes a percent. This calculator shows the new monthly number and what that does to a yearly housing budget. Landlords use it to preview a hike; tenants use it to compare staying vs moving.
Local rent-control caps, notice periods, and “just cause” rules are not modeled. A 3–5% annual increase is common in unregulated markets; some cities cap far lower. Always read the notice and the lease.
Formula
Worked example
$1,500 rent with a 10% increase is $1,650 per month — $150 extra, $1,800 more per year.

Frequently asked questions
How do I calculate a rent increase?
New rent = current × (1 + percent). A 10% increase on $1,500 is $1,650.
How much extra per year is 5%?
On $1,500, 5% is $75 a month and $900 a year.
Percent or dollars?
Notices use either. Switch the increase type so you do not mix 8% with $8.
Does this include utilities?
No. It is rent only. Add parking or pet rent into the current amount if they rise too.
Is a rent increase legal?
Depends on the lease, notice period, and local rent rules. This tool does not give legal advice.
