Tenant Lease Escalation Estimator
Forecast commercial rent increases under Fixed % or CPI escalation clauses. Enter values for instant results with step-by-step formulas.
Formula
Rent(Year n) = Base Rent × (1 + Rate)^(n-1)
Future rent is calculated using the compound interest formula. For each year, the rent increases by the escalation rate. Total Cost is the sum of all monthly payments over the term. NPV discounts these future payments back to today's dollars using the discount rate.

Frequently Asked Questions
What is a rent escalation clause?
A clause in a lease agreement that outlines when and by how much rent will increase. Common methods are fixed percentage increases (e.g., 3% annually) or variable increases tied to an index like CPI.
What is Fixed vs. CPI escalation?
Fixed escalation provides certainty (you know exactly what you'll pay). CPI escalation ties rent to inflation, protecting the landlord's purchasing power but creating risk for the tenant if inflation spikes.
What is a 'Gross Lease' vs 'Net Lease'?
In a Gross Lease, the landlord pays expenses (taxes, insurance, maintenance). In a Net Lease (NNN), the tenant pays base rent *plus* these expenses. Escalations usually apply to Base Rent only.
Is a longer lease better?
It secures your location and rate, but locks you into liability. Landlords often offer lower escalation rates or more concessions (TI allowance) for longer terms.
