Lease Calculator
Calculate monthly lease payments and total lease cost
How to Use This Lease Calculator
- Enter the asset value (MSRP for vehicles, purchase price for equipment)
- Input the residual value as a percentage (typically 50-60% for 36-month car leases)
- Specify the lease term in months (24, 36, or 48 months are common)
- Enter the money factor (divide APR by 2400 to convert interest rate)
- Add your down payment amount and any fees/taxes
- Click 'Calculate Lease' to see your monthly payment and total lease cost
Example: Lease a $40,000 car with 55% residual after 36 months, money factor 0.00125 (3% APR), $2,000 down, $500 fees. Monthly payment: approximately $450. Total lease cost: $18,200 over 3 years.
Tip: Negotiate the selling price (capitalized cost) before discussing monthly payments. A lower price reduces both depreciation and finance charges.
Why Use a Lease Calculator?
Understanding lease math helps you evaluate whether leasing makes financial sense and negotiate better terms.
- Compare the true cost of leasing vs. buying a vehicle
- Calculate how different residual values affect your monthly payment
- Understand what you're actually paying in finance charges (interest)
- Evaluate lease offers from different dealers or equipment suppliers
- Determine if manufacturer lease specials are actually good deals
- Budget for business equipment leases with accurate payment projections
Understanding Your Results
Your lease payment has two components: depreciation (the value you 'use up') and finance charges (interest on the money tied up in the asset).
| Result | Meaning | Action |
|---|---|---|
| Finance charges < 15% of payment | Low interest rate | Good financing terms. Focus negotiation on price and residual. |
| Finance charges 15-25% of payment | Moderate interest rate | Typical range. Shop rates if credit is strong; may get better terms. |
| Finance charges > 25% of payment | High interest rate | Consider financing alternatives or improving credit before leasing. |
| Total cost > 40% of asset value | Expensive lease | May be cheaper to buy, especially if you keep vehicles long-term. |
Meaning: Low interest rate
Action: Good financing terms. Focus negotiation on price and residual.

Action: Typical range. Shop rates if credit is strong; may get better terms.
Meaning: High interest rate
Action: Consider financing alternatives or improving credit before leasing.
Meaning: Expensive lease
Action: May be cheaper to buy, especially if you keep vehicles long-term.
Note: Leases work best when you drive under 12,000 miles/year, want a new car every 2-3 years, and can use the vehicle for business tax deductions.

Formula
Monthly Payment = Depreciation Fee + Finance Fee Depreciation Fee = (Cap Cost - Residual) / Term. Finance Fee = (Cap Cost + Residual) × Money Factor. Cap Cost = Asset Price + Fees - Down Payment.
Current Standards: Typical money factors range from 0.001 (2.4% APR) to 0.003 (7.2% APR). Residual values are set by lessors using industry guides. Strong credit (700+) qualifies for best rates.
Frequently Asked Questions
How do I convert money factor to APR?
Multiply the money factor by 2,400 to get the equivalent APR. A money factor of 0.00125 equals 3% APR (0.00125 × 2,400 = 3). Conversely, divide APR by 2,400 to find money factor. This helps you compare lease financing to loan rates.
What's a good residual value?
Higher residuals mean lower payments. For a 36-month car lease, residuals of 55-65% indicate vehicles that hold value well (Toyota, Honda, Lexus). Under 50% suggests higher depreciation. Luxury vehicles often have lower residuals but may be subsidized by manufacturers to make lease payments competitive.
Should I put money down on a lease?
Financially, it rarely makes sense. Down payments don't reduce total cost, they just front-load it. If the car is totaled, you lose that down payment since gap insurance only covers the lease payoff. Multiple first payments (MSDs) can sometimes reduce money factor instead.
What happens if I exceed the mileage limit?
You'll pay excess mileage fees, typically $0.15-$0.30 per mile, at lease end. On a 36,000-mile lease, driving 15,000 extra miles could cost $2,250-$4,500. If you know you'll exceed limits, negotiate higher mileage upfront (12,000, 15,000, or 18,000/year) at lower per-mile rates.
Is leasing or buying better financially?
Buying typically costs less over 5+ years of ownership. Leasing costs more but provides lower monthly payments and eliminates maintenance/repair concerns on newer vehicles. Leasing can make sense for business use (tax deductions), frequent upgraders, or those who prioritize cash flow over long-term cost.
