Formula
Increase % = (new rent − old rent) ÷ old rent × 100= 7.5
Note
This is a simplified model: it applies the standard property-management definition to the numbers you entered. Rent affordability uses a flat share-of-income rule and ignores credit history, local screening criteria and household size. Proration assumes a plain daily rate; your lease or local law may prescribe a different convention (for example a fixed 30-day month). Security-deposit interest is simple interest at the rate you enter, while many jurisdictions set the rate, the compounding and the payout schedule by statute. Income, expense, reserve and escalation figures are straight-line and assume the amounts you enter hold steady; they ignore taxes, depreciation, financing changes, capital events, inflation and market turnover. Lease buyout compares the contractual penalty with the remaining rent only and is not a reading of your lease. These results are general information, not legal, tax or investment advice: check your lease and local tenancy law and consult a qualified professional before acting.

How is the rent increase percentage calculated?+
It's calculated as (new rent minus old rent) divided by old rent, expressed as a percentage — a simple formula that shows how much a tenant's rent is rising relative to what they were previously paying.
Is there a legal limit on how much rent can be increased?+
It depends entirely on your jurisdiction — some cities and provinces/states have rent control or rent stabilization laws capping annual increases (often tied to inflation or a fixed percentage), while others have no legal cap at all; always check local regulations rather than assuming a specific limit applies everywhere.
What's a 'typical' or average rent increase?+
There's no universal typical figure since it depends heavily on local market conditions and vacancy rates, but landlords often benchmark against local rent growth data or inflation rates rather than picking an arbitrary number, especially in markets without rent control.
Does the increase percentage tell me if a raise is fair?+
It only tells you the size of the change, not whether it's justified — comparing it to local market rent growth, the property's operating cost increases, or comparable unit pricing nearby gives more context on whether an increase is reasonable.
Should I calculate the percentage on the old rent or the new rent?+
Standard practice divides by the old (starting) rent, not the new rent — dividing by the new rent instead would understate the percentage increase, since the same dollar increase represents a smaller share of the larger new figure.
