How to calculate a rent increase
- New rent from a percentage: current rent × (1 + percentage ÷ 100). A 4% increase on $1,500 is $1,500 × 1.04 = $1,560.
- Percentage from a new rent: (new rent − current rent) ÷ current rent × 100. Going from $1,500 to $1,575 is a 5% increase.
- Yearly cost: the monthly change × 12. That $75 increase costs the tenant $900 more over a year.

Notice and legal limits
Most places require written notice before rent goes up: commonly 30 days for month-to-month tenants, and 60 or 90 days in some states or for larger increases. During a fixed-term lease, rent generally can't change until renewal unless the lease says otherwise.
Most of the US has no cap on increases for market-rate units, but California, Oregon, and Washington have statewide limits for many properties, and cities with rent control have their own. Confirm the rules for the property's location before setting a number.
Setting a renewal increase as a landlord
Compare the current rent to similar units nearby, then weigh the increase against the cost of turnover: a vacant month, cleaning, and marketing often cost more than a smaller raise. If a unit does turn over, prorate the new tenant's first month with the prorated rent calculator and check they can carry the new rent with the rent-to-income calculator. Ready to tell the tenant? The rent increase letter generator writes the notice or renewal offer for you. Tenants facing an increase can check what still fits their budget with the rent affordability calculator.
Frequently asked questions
How do you calculate a rent increase percentage?
Subtract the current rent from the new rent, divide by the current rent, and multiply by 100. Going from $1,500 to $1,575 is a $75 increase, and $75 ÷ $1,500 = 5%.
What is a normal rent increase?
Renewal increases of about 3% to 5% a year are common, though they swing with the local market. Larger jumps tend to follow a stretch of below-market rent or a hot rental market.
How much notice does a landlord have to give for a rent increase?
Commonly 30 days for month-to-month tenancies, and longer in some places, such as 60 or 90 days for larger increases. For a fixed-term lease, rent usually can’t go up until the lease ends unless the lease allows it. Rules vary by state and city.
Is there a limit on how much rent can go up?
In most of the US there is no cap for market-rate units, but some states, including California, Oregon, and Washington, limit annual increases for many units, and some cities have rent control. Check the rules where the property is.
Can I negotiate a rent increase?
Often, yes. Landlords usually prefer keeping a reliable tenant over paying for vacancy and turnover. Comparable rents nearby, a strong payment history, or offering a longer lease can all help.
Filling a vacancy?
Send a free rental verification to an applicant's previous landlord, then see their estimated income from actual bank deposits.
