Lease Escalation Calculator
Project rent under a fixed annual escalation — the final-year rent, total rent over the term, and how much the escalations add versus flat rent.
How it works
Year n rent = base rent × (1 + escalation%)^(n − 1) · Total = sum of all years
A fixed-percentage escalation raises the rent by the same rate each year, so it compounds — the increase is applied to the prior year’s rent, not the original base. Over a multi-year lease that compounding meaningfully outpaces a flat rent, which is exactly why landlords use it to offset inflation and rising expenses. Tenants should budget from the final-year figure, not year one, since that is the rent they will actually be paying at renewal.
Worked example
A $60,000 base rent with a 3% annual escalation over five years runs $60,000, $61,800, $63,654, $65,564 and $67,531 — a $67,531 final year and $318,549 total, about $18,549 more than a flat $300,000.
Frequently asked questions
Is a fixed escalation compounded or simple?
This calculator uses a compounded escalation, the most common commercial structure: each year’s increase is a percentage of the previous year’s rent. A simple (fixed-dollar) bump grows more slowly because it always applies to the original base.
How does a percentage escalation compare to a CPI clause?
A fixed percentage is predictable and easy to budget, while a CPI-linked clause tracks actual inflation and can be higher or lower. Some leases combine them with a floor and a cap to bound the outcome.
Should I negotiate the escalation rate?
Yes — over a long term the escalation rate affects total cost as much as the starting rent. A one-point difference on a large lease compounds into serious money by the final year, so it is worth as much attention as the base.
