Lease vs Buy Car Calculator exists because people deserve accurate, transparent calculations they can trust — not vague rules of thumb. Compare the true cost of leasing versus buying a car — side by side, in your browser.
About FinCalc Media LLC: Lease vs Buy Car Calculator is an independent educational resource published by FinCalc Media LLC. Our calculators are informational tools and do not replace professional financial advice.
A small group of finance experts and engineers who believe a number is only useful when you understand where it comes from. We work distributed across the US, constantly refining the math.
Auto Finance Content Reviewers
Our team breaks down the brutal reality of auto finance. We run the exact same mathematical formulas used by dealerships, stripping away the sales pitch so you can compare your leasing and buying options with absolute confidence.
Product & Accessibility
Builds the calculation engine and keeps the site fast, accessible, and privacy-first across every device.
Lease vs Buy Car Calculator began as a frustration: most online calculators hand you a number with no explanation, no sources, and a page buried in ads. We wanted the opposite.
What started as one clean tool grew into a robust platform for calculating real auto financing costs — each component built to show its working and respect your privacy.
We turn established auto finance formulas into fast, accurate tools you can use in seconds — then wrap them in plain-English explanations of what the result actually means.
Our guides exist for the follow-up question every calculator should answer: “okay, so what do I do with this number?”
We earn trust the boring way: by showing our assumptions, citing published auto finance data, and being honest about where the estimates fall short of your specific deal.
You can read the methodology behind every calculation in the relevant guide, and cross-check every formula yourself.
Documented formulas
Each calculator explains the exact equation it uses and how edge values are handled.
Published rate data
Assumptions for money factor, residual values, and depreciation follow published auto finance benchmarks — not figures we invented.
Clear scope boundaries
We calculate, we don't advise. Every result page reminds you to confirm figures with your dealer or lender before signing.
“The most straightforward lease vs buy breakdown I've ever used. Saved me $3k on my new SUV.”
“Finally a tool that clearly explains money factor and residual value without hiding the math.”
Every result comes straight from the published formula — no rounding shortcuts, no averages standing in for the real calculation.
Rate assumptions follow published auto finance data from Experian, Edmunds, and the Consumer Financial Protection Bureau, with sources listed on every relevant page.
The calculator runs entirely in your browser. Nothing you enter is sent to a server, stored, or used to identify you.
Content and FAQs ship as crawlable static HTML. The interactive calculator hydrates on top without replacing the page.
We say where the numbers fall short — high-mileage drivers, early trade-ins, and manufacturer incentives all change the math — instead of pretending one scenario fits everyone.
The formula, the categories, the assumptions — all visible. Check the numbers against your own and verify every step.
