Terms of Service

By using proratacalc.com, you agree to these terms. They are intentionally short and plain.

What this site is

proratacalc provides single-purpose calculators that perform arithmetic and show the steps behind the result. The calculators are general tools for estimation.

Not professional advice

The results are not financial, tax, insurance, or legal advice, and are not a substitute for a qualified professional. Conventions, rates, and rules vary by contract, employer, insurer, and jurisdiction. Always confirm a figure against your own documents and, where it matters, a professional. You are responsible for how you use any result.

Provided "as is"

We work to keep the calculators accurate, but we make no warranty that they are error-free or fit for a particular purpose. To the fullest extent permitted by law, proratacalc.com is not liable for any loss arising from use of the site.

Changes

We may update these terms as the site grows. Material changes will be reflected on this page.
