Lease payment calculator
Enter the 5 numbers that set a lease payment: MSRP, negotiated selling price, residual percentage, money factor, and term. The calculator shows depreciation and rent charge separately, because that split is where lease deals are won and lost — and where markups hide.
Money factor 0.00275 is approximately 6.60% APR (money factor times 2,400). Residual $19,200.
| Line | Amount | Where it comes from |
|---|---|---|
| Adjusted cap cost | $30,000 | selling price minus money down |
| Depreciation charge | $300.00/mo | (adjusted cap − residual) ÷ 36 |
| Rent charge | $135.30/mo | (adjusted cap + residual) × money factor |
| Base payment, before tax | $435.30/mo | depreciation + rent charge |
| Total of base payments | $15,671 | over 36 months |
Not sure what money factor to use?
Ask the dealer for the money factor and the residual in writing before negotiating anything, and ask whether the factor matches the leasing company’s buy rate for your credit tier. Dealers can mark the factor up and keep the difference. For context, new-vehicle loan APRs averaged 6.39% in Q1 2026 per Experian, which converts to a money factor of about 0.00266. How the factor works, and how to spot markup, is covered in what is a money factor.
Read the rent charge line
The payment is what the dealership will discuss with you. The rent charge line is where the interest lives: (adjusted cap cost + residual) times the money factor, every month. Two quotes with the same payment can carry very different rent charges, and the one with more rent charge and less depreciation is the worse deal wearing the same clothes.
