Check your lease

Compare the estimate with the written terms.

Subtract current rent from proposed rent to find the monthly increase, then divide that increase by current rent to calculate the percentage. The result shows the math only. Whether an increase is permitted can depend on notice, tenancy type, location, exemptions, and the effective period.

How the math works

Increase percentage = (new rent - current rent) / current rent x 100.

  • Current and proposed rent cover the same unit and payment period.
  • Recurring fees are excluded unless included in the rent inputs.
  • The calculator does not apply rent-control or notice rules.

What to keep in mind

This is a planning estimate based on the numbers you enter. The lease, timing rules, and local requirements may affect the real amount or deadline.

Rent increase questions

How do I calculate a rent increase percentage?

Subtract old rent from new rent, divide by old rent, and multiply by 100.

How much more will I pay in a year?

Multiply the monthly increase by 12, assuming the new amount applies for a full year.

Does this check a local rent cap?

No. This page calculates the change but does not determine whether a proposed increase is allowed.
