Terms of use

Effective date: October 9, 2026

Using the calculators

WhatPer provides free online calculators for general information and personal planning. You may use the results for your own reference.

Estimates, not advice

Results depend on the information and assumptions entered and may be incomplete or inaccurate. They are not financial, tax, legal, or lending advice, a loan offer, or a guarantee. Mortgage calculations are estimates only; verify rates, payment amounts, fees, taxes, insurance, and loan terms with your lender.

Availability and changes

We may update, suspend, or discontinue parts of the site at any time. We aim to keep the calculators useful but do not promise uninterrupted access or error-free results.
