Rent increase calculator
See the new rent and the extra annual cost after a percentage increase.
What the result means
A rent increase is a percentage of current rent. State rules on notice periods and how often rent can rise are not applied here.
How it is calculated
New rent = current × (1 + %/100)
- Current: Rent for one payment period.
The extra annual cost if the figure is weekly uses × 52, matching the rent converter.
Assumptions
- Estimates only — not tax, legal, credit or financial advice. Check the official source or your contract before relying on a figure.
- No legal test of whether the increase is allowed.
Worked example
5% on $650 a week
A typical increase example.
- New weekly
- $682.50
- Extra yearly
- $32.50 × 52 = $1,690
A small weekly rise is a four-figure annual cost.
Check the tenancy rules in your state
Notice periods, frequency limits and how a dispute is lodged differ by jurisdiction. This calculator only does the arithmetic.
A 5% rise on $650 a week is $32.50, which looks small on a transfer and is $1,690 over a year. Convert the new weekly figure to monthly with × 52 ÷ 12 before you rewrite a budget that is paid monthly.
Questions
Can my landlord raise rent by this much?
That depends on your lease and state tenancy law, not on this percentage calculator.
Is the extra yearly cost weekly rise times 12?
No. Multiply the weekly rise by 52. $32.50 × 12 is $390; $32.50 × 52 is $1,690. The rent-conversions guide is the long version of that mistake.
