Tip. Negotiate with comparable listings in hand rather than with a feeling about fairness.

Assumptions

  • New rent = current rent × (1 + increase%).
  • The lease total assumes the new rent applies for every month of the term you enter.
  • Rent only. Any change to parking, pet rent, or amenity fees is separate and often moves at renewal too.
  • Local rent-control or notice rules are not modelled. This is arithmetic, not a legal check.

What this calculates

Shows the new rent, the monthly increase, and the total extra cost across the lease, so a percentage on a renewal letter becomes a real number.

How to use it

  1. Start with current monthly rent and work down the form, or load an example to begin from a realistic case.
  2. Read the headline result alongside the supporting rows, which show the intermediate figures behind it.
  3. Check the assumptions. They decide what the number includes and, more importantly, what it leaves out.
  4. Sweep increase on the response curve to see how much it actually moves the answer.
  5. Run a cautious case as well as an optimistic one before using the estimate in a decision.

Common mistakes

  • Reacting to the monthly figure and never calculating the lease total.
  • Comparing a raised rent to buying without re-running the cash needed to close.
  • Missing the notice deadline and rolling onto a month-to-month rate that is higher still.

Formula

New rent = current rent × (1 + increase%)

Inputs

  • Current monthly rent
  • Increase (%)
  • Lease months (mo)

FAQ

Are rent increases capped?

It depends entirely on local law. Some cities and states cap annual increases or require notice periods, and many places have no cap at all. This tool only does the arithmetic.

When is it worth moving instead?

Compare the lease total increase shown here against your move-in cash and moving costs. If a year of the increase is less than the cost of moving, staying is usually cheaper even when the increase feels unfair.

Can I negotiate a renewal?

Often, especially if you pay on time and the local market has softened. Turnover costs a landlord vacancy, cleaning, and listing time, which is real leverage if you can point to comparable listings.
