Rent Increase Calculator

Model how your rent will grow over time under a fixed annual rate, an inflation-linked rate, or a fully custom year-by-year schedule. See the monthly rent, annual total, and cumulative spend for every year of your lease horizon.

Projection Horizon (yrs):

Increase Mode:

Fixed % per year

Custom schedule

Annual Increase (%):

How It Works

Each mode applies a multiplier to the rent at the start of every year:

Fixed %: Rent_n = Rent₀ x (1 + r)ⁿ where r is the fixed annual rate.
Inflation-linked: The rate each year equals CPI + premium. Compounded year-by-year.
Custom schedule: You specify a different percentage for every year. Useful when a lease caps increases for early years and then allows higher ones later.

The Annual Total is the monthly rent multiplied by 12. The Cumulative Paid is the running sum of all annual totals from year 1 through that row. All calculations run in your browser; nothing is sent to a server.
