Auto Lease Payment and Lease-versus-Buy Calculator

Reproduce a lease disclosure or compare scheduled lease return with buying and selling, including the loan balance still owed at sale.

Use this result well

Inputs that matter
Disclosed gross capitalized cost, capitalized-cost reduction, dollar residual, money factor, whole-month term, periodic taxes/fees, and narrowly defined nonrefundable upfront charges
Output to expect
Adjusted capitalized cost, depreciation and rent charge, base and periodic payment, periodic-payment total, modeled scheduled cost, and nominal APR comparison
How it works
Regulation M lease-payment disclosure arithmetic using entered disclosure figures; the capitalized-cost reduction is separated from other upfront charges to prevent double counting
  • MSRP is not automatically gross capitalized cost; reconcile every input to the lessor’s itemization and amount due at signing.
  • Disposition, mileage, wear, insurance, registration, acquisition, tax, early-termination, purchase-option, and refundable-deposit terms require separate review.

Choose your path

Built around the job you need to finish

Reproduce a disclosed vehicle-lease periodic-payment scenario while keeping capitalized cost, upfront money, recurring charges, and omitted contract terms distinct.

First-time lessee

Understand the pieces of a quoted periodic payment.

Copy gross capitalized cost, reduction, residual, money factor, term, and recurring charges from the disclosure.

Can reconcile depreciation, rent charge, base payment, and periodic payment without substituting MSRP.

Quote comparer

Compare two lease disclosures on the same cost basis.

Enter one disclosure at a time, preserve the exact inputs, and compare periodic payment and modeled scheduled cost.

Does not double-count cap reduction or treat a nominal APR comparison as the legal APR of a loan.

End-of-lease risk reviewer

See costs that payment arithmetic does not capture.

Review mileage, wear, disposition, purchase-option, insurance, and early-termination terms in the source contract.

Does not authorize the lease from the calculator total alone.

Reference & details

How it works

Disclosure payment

Gross cap cost is the disclosed amount, not automatically MSRP. Money factor × 2,400 is only a nominal rate comparison.

Base payment = (adjusted cap cost − residual) ÷ months + (adjusted cap cost + residual) × money factor

Same-period cash comparison

Use one complete lease term and consistent operating costs. Buying includes scheduled loan payments made through sale and the remaining modeled loan principal.

Lease = upfront + scheduled payments + end charges + operating; buy = upfront + payments made + remaining loan + end charges + operating − gross sale proceeds

Scope of the loan balance

The buy loan assumes a fixed contract interest rate and end-of-month amortization. Obtain the lender’s actual payoff for a transaction. No discounting or tax deduction is applied.

Lease − buy: negative favors the entered lease cost; positive favors the entered buy cost

Example Scenarios

$42,000 gross cap cost, $3,000 reduction, $24,360 residual, factor 0.00125 and 36 months, with $45 monthly taxes/fees.

$530.87 periodic payment; separate upfront and return terms still need review.

36-month lease: $2,000 upfront, $400/month, $600 end, $3,000 operating. Buy: $5,000 upfront, $30,000 zero-interest loan for 60 months, $2,000 operating, $18,000 sale.

Lease $20,000; buy $19,000, including $12,000 outstanding loan principal; difference $1,000.

Common Mistakes to Avoid

Subtracting resale while omitting outstanding debt

Add the loan still owed at sale or use a consistently defined equity figure, never a mixture.

Adding the first lease payment twice

Count every scheduled payment once; separate only other upfront amounts.

FAQ

Selling a vehicle does not cancel its loan. The comparison adds the modeled remaining principal at the sale date, then subtracts gross sale proceeds. Sale proceeds and equity are different amounts.

This comparison assumes return at the end of the full scheduled term. Early termination and a lease purchase require actual contract payoff, charges and tax treatment outside this mode.

Include nonrefundable upfront cash, including cash cap reduction and any applied net positive trade equity. Exclude a first periodic payment already in the scheduled-payment count and a refundable deposit returned in full.

Use Save planning case in the comparison mode. Copy MD includes its entered assumptions; Download CSV contains the result breakdown. Keep a separate copy of actual lender and lessor disclosures.
