01 / Method
Translate the clause into dated rates.
A useful escalation analysis shows every lease year, the applied adjustment, the rate per square foot, monthly base rent, annual base rent and cumulative term rent. Fixed percentage scenarios compound on the immediately preceding rate in this tool; fixed dollar scenarios add the entered amount per square foot each year.
The executed clause can work differently. Verify the adjustment date, base amount, compounding rule, rounding, partial periods, deferrals, options and any irregular steps before relying on the schedule.
02 / Index-linked scenarios
CPI is not a self-defining input.
Statistics Canada publishes multiple CPI series and recommends that contract escalation provisions define the index, reference periods, publication timing, calculation and treatment of rebasing, revisions or successor indexes. This calculator does not choose that legal or economic definition.
Index mode applies one assumed annual percentage change after the entered floor and cap. It is a sensitivity—not a forecast, retrieved CPI observation or calculation under a particular lease.
03 / Scope
Base rent is only one cash-flow stream.
The schedule excludes additional rent, operating-cost reconciliations, tax, utilities, parking, storage, percentage rent, free rent, tenant allowances, landlord work, restoration, renewal periods and present value. Use the commercial lease cost calculator for a first-year occupancy-cost comparison and the net effective rent guide for broader term economics.
04 / Review and accountability
A reproducible scenario—not lease advice.
Commercially Research & Editorial prepared this tool and Slav Loban, Commercial Real Estate Division Leader, reviewed its commercial workflow on August 26, 2026. It does not interpret a lease, calculate a legal payment obligation, prepare an invoice, predict an index or provide legal, tax, accounting, appraisal or investment advice.
