Embed terms

Free for any use, with one ask. Please keep the small attribution link visible — it's how we sustain a free, ad-free, tracking-free tool. We kindly request the calculator not be embedded on sites engaged in deceptive lending or predatory financial products.

Privacy & performance. The widget is fully client-side and loads ~50 KB. The only third-party request is to Google Fonts (per Google's privacy policy). No analytics, no cookies, no user tracking on our end.

No warranty. Estimates only — see our full disclaimer. We update the widget continuously; embedding by URL means you always get the latest version.

FAQ

Is this really free?

Yes. No fee, no signup, no API keys. The widget is hosted on our infrastructure at no cost to you.

Will it slow down my page?

The widget is ~50 KB and loads in its own iframe, so it doesn't block your page rendering. It uses native browser APIs only — no heavy frameworks.

Does it work on mobile?

Yes. The widget is responsive down to 280 px wide, suitable for narrow sidebars and mobile screens.

Can I change the loan terms shown?

Not currently — the widget shows 36 / 48 / 60 / 72 / 84 month options, which cover ~98% of auto loans. If you have a specific need, email us.

Can I host the widget on my own server?

You can, but we recommend embedding by URL so you receive bug fixes and tax-table updates automatically. If you have a strong reason to self-host (air-gapped intranet, etc.), email us.

Will the calculator's results match my final loan offer?

The calculator uses the standard amortization formula (the same math banks use). Results will match your lender's estimate to the cent for the inputs you provide. Actual loan offers may vary based on dealer fees, lender rounding, and credit profile — see our disclaimer.
