Free trucking calculator widget for your website

Dispatch services, factoring companies, CDL schools, trucking blogs and accountants can add our IFTA fuel tax calculator or cost-per-mile calculator to any page for free. Paste one snippet. When the official IFTA tax matrix changes each quarter (3Q2026 is live now), your embedded calculator updates automatically. You don't have to maintain anything.

Quarterly IFTA estimate by jurisdiction using the official current-quarter tax matrix.

The terms

Free. No account, no API key, no fee.
No ads or tracking cookies inside the widget. It runs the same calculator as our site, and inputs stay in the visitor's browser.
Attribution. Please keep the small "by FuelTaxMath" line under the widget. Adding rel="nofollow" to that link is fine.
Estimates only. The widget shows a disclaimer that it isn't tax advice. Filers should still confirm with their base jurisdiction.

Where it fits

Dispatcher and factoring sites: a "driver tools" or resources page.
CDL schools: owner-operator business or IFTA lesson pages.
Trucking accountants and permit services: an IFTA filing page, so clients can sanity-check a quarter before sending paperwork.
