How We Calculate Lease and Finance Estimates
The formulas behind our public calculators and estimated monthly payments.
Lease payment
Depreciation = (capitalized cost − residual) / term months. Rent charge = (capitalized cost + residual) × money factor. Monthly = depreciation + rent charge. Money factor × 2400 ≈ APR.
Finance payment
Standard amortization: monthly = principal × r / (1 − (1 + r)^−n), where r = APR / 12 and n = term months.
What is not included
Our estimates are pre-tax and do not include lender-specific fees, provincial registration, air/tire levies, or dealer-specific administration fees unless the dealership entered them into the listing.
