Rent increase tool

Rent Increase Calculator

Enter a percentage or fixed amount to calculate the arithmetic change in rent. The result does not decide whether an increase is permitted; legal limits, exemptions, notice requirements, and local rules may apply.

Projection by increase step

Percent mode compounds. Fixed mode adds the same annualized amount each step.

Assumptions used on this page
  • 1 year = 365 days
  • Biweekly = 14 days
  • 4-week rent = 28 days
  • Month = 365 ÷ 12 days (average)
  • This tool does not assume what is included in “rent” such as fees, utilities, or taxes. Enter the total you want to budget with.

How this calculator worksRent increase calculator

Enter the current rent, choose a percentage or fixed-amount increase, and see the resulting rent. The calculator also shows the difference for the selected payment period and its annualized impact.

What this calculation clarifies

  1. 1
    Percentage increase formula

    Increase amount = current rent × percentage ÷ 100. The resulting rent is the current rent plus that calculated increase.

  2. 2
    Fixed increase formula

    New rent = current rent + fixed increase. The fixed amount uses the same payment period as the current rent you enter.

  3. 3
    CPI is an entered scenario

    The calculator does not retrieve official CPI data. Any percentage is supplied by you, the result is arithmetic only, and no jurisdictional cap is applied automatically. Verify any applicable CPI figure or legal rule separately.

Worked examples

$1,538 with a 7.5% increase

$1,538 increased by 7.5% becomes $1,653.35. The monthly change is $115.35, and the annualized change is $1,384.20.

$800 rent with a $70 increase

$800 plus $70 becomes $870. Over a year, that fixed increase adds $840 before any later changes.

Checking a projection

One increase is one-step arithmetic. If you enter more than one percentage increase, each step applies to the prior result; use the compound calculator for a dedicated year-by-year annual view.

Useful context

  • Monthly and annualized differences follow the visible payment-period assumptions; they do not determine whether an increase is permitted.
  • If you know only the starting and new rent, use the percentage calculator to find the arithmetic percentage change.

Official rent-increase resources

Use the calculator to check entered arithmetic, then verify current requirements with the relevant government or tribunal. RentConverter does not apply the rules from these resources automatically.

When rent increase context helps

  • Checking a renewal notice before responding.
  • Comparing the new rent with your affordability limit.
  • Understanding whether a fixed increase or percent increase changes the yearly budget more.

Check before relying on it

  • Local law and lease terms can control whether an increase is allowed. This page only calculates the numbers.

Frequently Asked Questions

What does this rent increase calculator show?
It shows the new rent after a percentage or fixed increase. It also shows the annual impact, average monthly amount, weekly amount, and 4-week amount.
How are percentage rent increases calculated?
Percentage increases are applied to the current rent. If you project more than one increase, each increase compounds from the previous result.
How are fixed rent increases calculated?
A fixed increase is added in the same billing period as the rent you entered. The calculator annualizes that amount so the results can be compared across monthly, weekly, and 4-week periods.
Why are monthly rent and 4-week rent different?
A 4-week period is 28 days. An average month is about 30.42 days based on 365 days divided by 12. That difference changes the annual total.
Does this calculate prorated rent after an increase?
No. This page estimates full-period rent after an increase. If an increase starts partway through a billing period, the first payment may need a separate proration calculation.
Can I use this for lease renewal planning?
You can use it to check the arithmetic for an entered proposal. The result does not determine whether an increase is permitted or whether notice, exemption, or local-rule requirements are satisfied.
Does the calculator apply a legal rent-increase limit?
No. It applies only the percentage or fixed amount you enter. Verify current limits, exemptions, notice requirements, and local rules with the relevant official authority.
What assumptions does this page use?
The calculator uses 365 days per year, 7 days per week, 14 days for biweekly rent, 28 days for every 4 weeks, and 365 ÷ 12 days for an average month.
