Car Lease Calculator

Quick answer

The car lease calculator works out your monthly lease payment from the MSRP, negotiated price, residual value, money factor (or APR), term, down payment, trade-in, rebates, fees and sales tax – showing the depreciation and finance charges.

Lease payments mainly cover the car’s depreciation over the lease, plus a finance charge. A high residual value and a low money factor make a lease cheaper. Negotiate the price just like a purchase – it is rarely fixed.

How to use the Car Lease Calculator

  1. MSRP
  2. Negotiated price
  3. Lease term
  4. Residual value
  5. Interest given as
  6. Money factor

  9. Trade-in value
  10. Rebates and incentives
  11. Acquisition and dealer fees
  12. Sales tax

Results update as you type, and every field accepts the units shown in its menu.

How it works

Enter the MSRP, negotiated price, term, residual percentage, money factor or APR, down payment, trade-in, rebates, fees and sales tax.

Tips

  • Use your real spending from bank statements rather than guesses.
  • Automate savings so they happen before you spend.
  • Revisit your plan once a year or after any big life change.
  • Keep an emergency fund before investing for long-term goals.

Common mistakes to avoid

  • Underestimating irregular expenses such as car repairs, gifts and annual bills.
  • Ignoring inflation for long-term goals.
  • Taking on high-interest debt to fund wants.

What each result means

  • Equivalent APR = [Money factor used]×2400
  • Net capitalized cost = [Negotiated price] + [Acquisition and dealer fees] – [Down payment (cap cost reduction)] – [Trade-in value] – [Rebates and incentives]
  • Residual value = [MSRP]×[Residual value]÷100
  • Monthly depreciation fee = ([Net capitalized cost] – [Residual value])÷[Lease term]
  • Monthly finance fee = ([Net capitalized cost] + [Residual value])×[Money factor used]
  • Monthly payment before tax = [Monthly depreciation fee] + [Monthly finance fee]
  • Monthly payment with tax = [Monthly payment before tax]×(1 + [Sales tax]÷100)
  • Total cost of the lease = [Monthly payment with tax]×[Lease term] + [Down payment (cap cost reduction)] + [Trade-in value] + [Rebates and incentives]×0

Example values

How the main result changes when MSRP changes and everything else stays at the example values above:

MSRP Monthly payment with tax
20,000 868.59
30,000 711.71
40,000 554.84
50,000 397.97
60,000 241.09
80,000 -72.65

Formula

Net capitalized cost = negotiated price + fees − down payment − trade-in − rebatesResidual value = MSRP × residual %Depreciation fee = (net cap cost − residual) ÷ termFinance fee = (net cap cost + residual) × money factor (= APR ÷ 2400)Payment = (depreciation + finance) × (1 + sales tax)

Worked example

Inputs — MSRP: $40,000; Negotiated price: $37,500; Lease term: 36 months; Residual value: 58 %; Interest given as: Money factor; Money factor: 0.0025; APR: 6 %; Down payment (cap cost reduction): $2,000; Trade-in value: $0; Rebates and incentives: $0; Acquisition and dealer fees: $995; Sales tax: 7 %.
Results — Money factor used = 0.0025; Equivalent APR = 6 %; Net capitalized cost = $36,495.00; Residual value = $23,200.00; Monthly depreciation fee = $369.31; Monthly finance fee = $149.24; Monthly payment before tax = $518.54; Monthly payment with tax = $554.84; Total cost of the lease = $21,974.28.

Frequently asked questions

What is a money factor?

The lease's interest rate expressed as APR ÷ 2400.

What is a good residual value?

Higher is better for the lessee – 55–65% for a 36-month lease is common.

Should I put money down on a lease?

Keep it small; if the car is totalled early, the down payment is usually lost.

What formula does the Car Lease Calculator use?

Net capitalized cost = negotiated price + fees − down payment − trade-in − rebates.
