What This Calculator Does
This rent increase calculator helps landlords and property managers calculate new rent amounts after a percentage increase and project future rents over multiple years. It shows the dollar increase per month, the additional annual revenue, and a multi-year projection table so you can plan income growth and compare against local market trends and inflation.
The Formula
A simple percentage increase is applied to the current rent. For multi-year projections, the formula compounds annually, meaning each year the increase is applied to the previous year rent rather than the original rent. This compound growth mirrors how most landlords apply annual increases.
Step-by-Step Example
Enter current rent
Your current monthly rent is $1,500.
Set increase percentage
You plan a 4% annual increase, which is near the national average for 2026.
Calculate new rent
$1,500 x 1.04 = $1,560 per month. That is a $60 monthly increase or $720 more per year.
Review projections
After 5 years at 4% annual increases, rent grows to $1,825 per month, a cumulative increase of 21.7% from the original $1,500.
Real-World Use Cases
Annual Lease Renewal
Determine a fair rent increase that keeps pace with market rates and inflation while retaining good tenants.
Investment Property Underwriting
Project future rental income when analyzing a property purchase to estimate long-term cash flow and return on investment.
Rent Control Compliance
In rent-controlled markets, verify that your planned increase stays within the legally allowed percentage cap.
Common Mistakes to Avoid
Raising rent above market rate, which increases vacancy risk. Always compare your rent to comparable properties in the area before setting increases.
Not providing proper legal notice. Most states require 30 to 60 days written notice before a rent increase takes effect.
Ignoring rent control or stabilization laws. Cities like New York, San Francisco, and Los Angeles have strict limits on annual rent increases for covered units.
Applying increases inconsistently across similar units, which can create fair housing concerns.
