How to use the Rent Increase Calculator
Choose what you know: the percentage, the new rent or the increase amount.
Enter the current monthly rent and the increase.
Optionally enter a rent cap (your local limit or a lease clause) to check the increase.
Set the years to project and a yearly increase for later years.
Calculate and review the new rent, the cap check and the projection table.
Rent increase formulas
Percentage increase = (new rent − current rent) ÷ current rent × 100
New rent = current rent × (1 + increase % ÷ 100)
Maximum rent under a cap = current rent × (1 + cap % ÷ 100)
Rent after y years = rent × (1 + yearly increase %)y

Tips for tenants and landlords
Check the lease: fixed-term leases usually lock the rent until renewal.
Check local rules on caps, exemptions and required written notice before an increase takes effect.
Compare with the market: similar units nearby show whether the increase is in line.
Subtract the old rent from the new rent, divide by the old rent and multiply by 100. For example, going from $1,800 to $1,950 is ($1,950 − $1,800) ÷ $1,800 × 100 = 8.33%.
How do I find the new rent from a percentage?
Multiply the current rent by (1 + percentage ÷ 100). A 5% increase on $1,800 is $1,800 × 1.05 = $1,890.
How much can a landlord raise the rent?
It depends on where you live. Many places have no limit for market-rate housing, while others cap yearly increases. For example, California's statewide law (AB 1482) limits most covered units to 5% plus local inflation, with a 10% maximum, and Oregon limits covered units to 7% plus inflation, also with a 10% maximum. Rules, exemptions and notice periods change, so check your local law.
How much notice is required for a rent increase?
Notice rules vary by state, province or country and often depend on the size of the increase and the lease type. Common requirements are 30 to 90 days' written notice. In most places rent cannot be raised during a fixed-term lease unless the lease allows it.
What is a typical yearly rent increase?
Increases often fall somewhere around 2% to 5% a year in stable markets, but they vary widely by city and year. Use the projection to see how a steady yearly increase compounds.
Does the projection compound?
Yes. Each year's rent is the previous year's rent times (1 + yearly increase). Four yearly increases of 3% raise rent by about 12.6% in total (1.03⁴ = 1.1255), not 12%, because each increase applies to an already higher rent.
