About CalcYeti

CalcYeti is a free collection of 24+ online calculators for money, math and everyday life. We started it for a simple reason: most people just want a quick, trustworthy answer — how much a loan will cost, how their savings might grow, what a tip should be — without wading through ads-first pages, sign-up walls, or maths they can't check.

What we believe

A good calculator should be fast, accurate, and honest about its limits. Every tool here uses the same standard formulas that banks, lenders and textbooks use, and every page explains exactly how the result is worked out so you can verify it yourself. We'd rather show our working than ask you to take our word for it.

How our calculators work

All calculations run entirely in your browser. The numbers you type never leave your device and are not stored or sent to us. That means your financial and personal figures stay private, and the tools work instantly.

Our limits

Our calculators are for general information and education. They are not financial, investment, tax, legal or medical advice, and they can't account for your full personal circumstances. For important decisions, please speak to a suitably qualified professional. See our disclaimer for details.
