Car Lease Calculator

Live lease payment board that splits depreciation fee from rent charge, peels money factor into an APR sketch, and ladders term lengths with residual held fixed for sensitivity.

Consumer lease literacy only. Not a dealer quote, lease contract, or credit decision. Mileage, wear, tax timing, and credit tier change real offers; confirm the worksheet before you sign.

Depreciation fee vs rent charge

A typical closed-end lease payment is not a mystery lump. It is mostly two classroom pieces: a depreciation fee that spreads (cap cost − residual) across the term, and a rent charge that applies the money factor to (cap + residual). Tax may sit on top depending on where you live.

This page’s framing is a dep vs rent twin, with a money-factor peel, a due-at-signing peel, and a term ladder that holds residual fixed for sensitivity. It is not insurance’s coverage stack, not the auto-loan equity race, and not depreciation’s year cliff board.

Decision framing: “How much of my payment is wearing the car down versus paying for money, and how does term length move that split?”

Consumer lease literacy only. Not a dealer quote, lease contract, credit decision, or tax opinion. Mileage caps, wear charges, and manufacturer programs change real offers. See our disclaimers.

Money-factor peel

Dealers often quote a tiny money factor instead of a familiar APR. A common conversion sketch is APR ≈ MF × 2400. The peel prints both so a 0.0025 factor does not look “small” when it behaves like a high rate.

Load Compact 36, then Pricey MF. Watch rent charge jump while depreciation stays in the same neighborhood.

Due-at-signing peel

Drive-off cash is more than the monthly line. This sketch adds down / cap reduction, first payment, and an optional acquisition fee. Registration and documentation still live on the dealer worksheet.

Term ladder with residual held fixed

Compare 24, 36, 39, and 48 months on the same cap, residual, and money factor. Longer terms shrink the monthly depreciation fee in this model. Real residuals often change by term; treat the ladder as sensitivity, not four simultaneous offers.

What the panel actually computes

Standard consumer lease payment literacy.

dep_fee = (cap_cost − residual) / term_months rent_charge = (cap_cost + residual) × money_factor base_payment = dep_fee + rent_charge monthly = base_payment × (1 + tax%/100) APR_sketch ≈ money_factor × 2400 due_at_signing ≈ down + first_month + acquisition_fee

Where this hands off

After a lease payment sketch, hand off for ownership financing, budget fit, residual value curves, or insurance stack literacy.

Loan amortization: auto loan calculator
Payment vs income rules: car affordability
Value over years: car depreciation
Premium stack sketch: car insurance

Worked scenarios

Scenario A: Compact 36. Cap $28k, residual $16k, MF 0.00145. Twin shows dep vs rent; due-at-signing includes acquisition.

Tap 24 vs 48 on the ladder with residual held. Depreciation fee per month moves hard; rent charge stays tied to MF.

Scenario B: SUV 36. Higher residual share softens depreciation; money factor still prices the rent line.

Scenario C: Short 24. Same literacy with a shorter runway; short-term narrative flags denser monthly depreciation.

Scenario D: Pricey MF. Rent charge dominates the story even when residual looks fine. Negotiate factor and cap, not only payment.

Common mistakes

Comparing only monthly payment to a loan payment without equity or residual risk.
Ignoring money factor because the decimal “looks small.”
Assuming every term uses the same residual in a real quote.
Forgetting acquisition fees and tax timing in drive-off cash.
Using this instead of the auto loan tool when the question is ownership amortization.
Treating the sketch as a signed lease or credit approval.

How to use this panel

Load a preset or enter cap cost, residual, money factor, and term.
Add down payment, tax on payment, and acquisition fee if you have them.
Read dep vs rent, money-factor peel, due-at-signing, and the term ladder.
Share when you want URL state. Typing does not rewrite the address bar. Confirm every figure on the dealer worksheet before you sign.

When not to stop at a lease sketch

Stop here for payment structure literacy. Hand off for loans, affordability, depreciation, or insurance. For mileage overages, early termination, and credit tier, talk to the lessor and read the contract.

Auto loan: auto loan.
Affordability: car affordability.
Depreciation: depreciation.

Frequently asked questions

How does this car lease calculator work?

It splits the monthly base payment into a depreciation fee ((cap − residual) / months) and a rent charge ((cap + residual) × money factor), then optionally adds sales tax on the payment. A money-factor peel shows the common MF × 2400 APR sketch, and a term ladder compares 24–48 month payments with residual held fixed for literacy.

What is cap cost vs residual?

Cap cost is the negotiated price the lease is based on. Residual is the contracted value at lease end. You pay for the gap (depreciation) plus a finance-style rent charge on the sum of cap and residual.

What is a money factor?

A money factor is the lease interest rate expressed as a small decimal (for example 0.00145). A common classroom conversion is APR ≈ money factor × 2400. Dealer worksheets may quote either form; this board uses money factor as the input.

Why hold residual fixed on the term ladder?

Real residuals often change by term. Holding residual fixed isolates how term length changes the depreciation fee per month. Treat it as a sensitivity sketch, not a binder quote for every term.

What is due at signing in this sketch?

Down / cap reduction + first monthly payment + optional acquisition fee. Real drive-off can also include registration, documentation, and state-specific taxes. Confirm the dealer worksheet.

Is this a dealer lease quote?

No. It is consumer lease literacy only. Credit tier, manufacturer programs, mileage bands, wear charges, and local tax rules change the real number. Not credit, tax, or contract advice.

How is this different from auto loan or depreciation tools?

Auto loan builds ownership with amortization. Depreciation sketches market value over years. This page is lease payment structure: depreciation fee vs rent charge, money factor, and term sensitivity.
