Terms of use
Updated
By using TRIR Calc (trircalc.com) you agree to these terms.
Estimates, not official determinations
The tools give estimates from published rules and tables, and each page cites its sources. Official figures come from the agency responsible. Confirm anything that matters with them before you rely on it.
No warranty
The site is provided as is. We work to keep it accurate and current but can't guarantee it is free of errors.
Purchases and refunds
Products sold on this site are digital downloads for your own use in one household or business. Please don't share or resell the files. Prices are in US dollars and are shown before you pay. Stripe processes the payment.
This is a digital download: nothing is shipped. After payment, the files are on the confirmation page and the link is emailed to you. Each link works for 72 hours and 10 downloads, and we'll send a new one if you need it.
If the files don't work for you, email hello@trircalc.com within 30 days of your purchase for a full refund. A refund switches off the download link.
The products carry the same limits as the free tools: they give estimates from published rules and are not professional advice. They are provided as is, and our liability for a product is limited to what you paid for it.
