How does this calculator work?
New rent = current rent + flat increase, or current rent × (1 + % ÷ 100) for a percentage raise. Enter the current amount and the increase type to get the new monthly rent, the exact increase in currency, and how much more you'll pay each year.
Formula
How this is calculated
Landlords typically express a rent review in one of two ways: a fixed flat increase (e.g. +$75 per month) or a percentage increase tied to inflation, a cost-of-living index, or a local rent-guideline rate. This calculator handles both. Enter the current monthly rent and choose whether the increase is a percentage or a flat amount, then enter the value.
For a percentage increase, the new rent equals the current rent multiplied by (1 + rate / 100). For a flat increase, the new rent is simply the current rent plus the fixed amount. The tool also scales the result to annual figures — the annual cost difference is the monthly increase multiplied by 12.
Note that many jurisdictions cap how much a landlord can raise rent in a single year (for example, tied to the Consumer Price Index or a government-set guideline). This calculator computes the arithmetic only; always verify compliance with local tenancy law before applying an increase.
Frequently asked questions
Multiply your current monthly rent by the percentage and divide by 100. For example, a 5% increase on $1,500 rent equals $1,500 × 5 ÷ 100 = $75 per month, bringing the new rent to $1,575.
Yes in many countries and states. Common caps link the allowed increase to the local CPI or a government guideline (for example 2–5% in many Canadian provinces, or linked to inflation in several EU countries). Always check your jurisdiction's tenancy authority before issuing or accepting a rent increase notice.
Notice periods vary widely: 30–60 days is common in the US, 90 days in many Canadian provinces, and 3 months in parts of the EU. Check the rules in your region — a rent increase applied without proper notice is often legally invalid.
