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

Rent increases are easier to judge when you can see the new rent, the monthly difference, and the annual impact together. This is useful for renewal notices, negotiation, and budget planning.

What this calculation clarifies

  1. 1
    Percent and fixed increases behave differently

    A percentage increase scales with the current rent. A fixed increase adds the same dollar amount. Over multiple years, percentage increases can compound.

  2. 2
    Annual impact is often clearer than monthly change

    A small monthly increase can become a larger yearly cost. Annual impact helps you compare renewing, moving, or negotiating.

  3. 3
    Rules and caps are outside the math

    Local rent rules, notice periods, CPI caps, lease terms, and exemptions can matter. The calculator gives the math, not legal permission.

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

If rent rises by the same dollar amount each year, the pattern is linear. If it rises by a percent each year, the pattern compounds and later years increase more.

Useful context

  • Use this for rent increase calculator, rent increase percentage calculator, annual rent increase calculator, and calculating rent increase searches when they match the page.
  • If you only know the old and new rent, use the percentage calculator. If you know the percentage and need the new rent, use rent after increase.

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?
Yes. It is useful for estimating the cost of a proposed rent increase before renewing a lease, comparing options, or checking the annual impact of a rent change.
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.
