What is the rent increase calculator — monthly & annual cost?

In short

A 5% rent increase on $2,000/mo raises your monthly cost by $100, your annual cost by $1,200, and adds $1,200 to a 12-month lease. Average U.S. rent increases in 2024 were 3–5%. Many cities cap rent increases at 3–8% annually.

Calculates the exact dollar impact of a rent increase — new monthly rent, monthly increase, annual increase, and total extra cost over the remaining lease.

How to use this calculator

  1. 1Enter your current monthly rent.
  2. 2Enter the proposed rent increase percentage.
  3. 3Enter months remaining on your lease to see total extra cost.

The formula

new rent=current rent×(1+increase %100)
total extra=(new rent−current rent)×months
New Rent = R × (1 + p/100); Monthly Increase = New Rent − R; Annual = Monthly × 12; Total Extra = Monthly × m
R
— Current monthly rent
p
— Increase percentage
m
— Months remaining
