Lease vs Buy Car Calculator

Lease vs Buy Car Calculator

Compare the total cost of leasing versus buying any vehicle side by side in seconds.

Last updated:

Typical new car: 15-20% per year

Multiply by 2400 to get approx APR

How it works

  1. Enter the vehicle basics

    Type the vehicle price (MSRP), any down payment, and your local sales tax rate. These feed both the lease and the buy calculation.

  2. Add your loan and lease terms

    Fill in the buy side β€” loan term and APR β€” and the lease side β€” term, money factor, and residual value. Defaults reflect typical 2026 deals.

  3. Compare the real numbers

    See monthly payments for both options, the total cost of each over the full term, and which choice saves you money once resale value is counted.

How Lease vs Buy Cost Is Calculated

A lease payment has two parts. The depreciation charge is the capitalized cost minus the residual value, divided by the lease term β€” it pays for the value the car loses while you drive it. The finance charge is the capitalized cost plus the residual value, multiplied by the money factor β€” it is the lease's version of interest. The money factor looks tiny, but multiply it by 2,400 and you get its approximate APR, which lets you compare lease financing directly against a loan rate. Buying uses standard loan amortization: the monthly payment is the financed amount spread over the term at the monthly interest rate. But the monthly payment is not the true cost. When you buy, you own an asset, so the real cost is your total payments minus the car's resale value at the end of the term. That resale value is why buying can be cheaper over the long run even when its monthly payment is higher than a lease β€” at the end you still have something worth selling, whereas a lease leaves you with nothing.

Lease Payment = [(Cap Cost βˆ’ Residual) Γ· Term] + [(Cap Cost + Residual) Γ— Money Factor]

Buy Payment = P Γ— [r(1+r)ⁿ] Γ· [(1+r)ⁿ βˆ’ 1]
Example

A $35,000 car with $2,000 down. Lease: 36 months, money factor 0.00125, 55% residual ($19,250), $650 acquisition fee. Monthly lease β‰ˆ $499 and total lease cost β‰ˆ $20,905. Buy: 60 months at 6.5% APR. Monthly buy payment β‰ˆ $694 and, after subtracting an estimated $15,530 resale value, the net buy cost β‰ˆ $28,088. Over these terms leasing costs roughly $7,180 less out of pocket β€” though the buyer ends up owning a car still worth about $15,500.

Scenario A β€” Budget sedan, short lease vs long loan$24,000 MSRP Β· Lease 36mo @ 0.00120 MF, 58% residual Β· Buy 72mo @ 7% APRLease β‰ˆ $300/mo, buy β‰ˆ $400/mo; buy wins on net cost thanks to resale value
Scenario B β€” Luxury SUV where lease wins on monthly cost$68,000 MSRP Β· Lease 36mo @ 0.00150 MF, 60% residual Β· Buy 60mo @ 6.5% APRLease β‰ˆ $850/mo vs buy β‰ˆ $1,330/mo; lease far cheaper month to month
Scenario C β€” High-mileage driver where buying wins$32,000 MSRP Β· Lease 36mo (mileage overage likely) Β· Buy 60mo @ 6% APR, kept 8 yrsBuying wins β€” no mileage penalties and value continues past the loan payoff
Scenario D β€” Low down payment scenario$40,000 MSRP Β· $0 down Β· Lease 39mo @ 0.00125 MF Β· Buy 72mo @ 6.5% APRLease β‰ˆ $520/mo, buy β‰ˆ $640/mo; lease lowers upfront cash but builds no equity
Scenario E β€” End of lease vs ownership equity$45,000 MSRP Β· Lease 36mo (return car, $300 disposition) Β· Buy 60mo (own outright)Lease ends with $0 equity; buyer owns a car worth ~$22,000 after the loan term
Scenario F β€” Three short leases vs one long ownership$30,000 MSRP Β· Three back-to-back 36mo leases (9 yrs) vs one 60mo loan kept 9 yrsRepeated leasing costs more over 9 years than buying once and driving it paid off

Quick facts

  • The average new-car lease payment in early 2026 is about $659 per month.
  • The average new-car loan payment in early 2026 is about $682 per month.
  • The average transaction price of a new car in 2026 is roughly $48,000.
  • A higher residual value lowers the depreciation portion of a lease, making the monthly payment cheaper.
  • Most leases cap mileage at 10,000–15,000 miles per year, with overage charges of 15–30 cents per mile.
  • Money factor Γ— 2,400 gives the lease's approximate annual interest rate.
