About Tokealo
What Tokealo is
Tokealo is a free collection of online calculators, converters, and everyday tools. The idea is simple: when you need a quick answer, you should get it in seconds, without sitting through a signup form, a paywall, or a wall of ads before the result. You type your numbers, you read the answer, and you move on with your day.
Every tool runs right in your browser. There is nothing to install and no account to create. Each one does a single job and tries to do it clearly, with the formula and a short explanation alongside the result so you can see how the number was reached.
What you can do here
The site is organized into a handful of categories so you can find the right tool fast:
- Finance: loan, mortgage, compound interest, salary, sales tax, and discount calculators.
- Health: BMI, BMR, calorie, body fat, sleep, and other wellbeing estimates.
- Converters: length, weight, temperature, volume, area, speed, and data storage.
- Education: GPA, grade, average, and quadratic equation tools.
- Home and DIY: paint, tile, concrete, mulch, and square footage calculators.
- Everyday: age, date, tip, percentage, and reading-time tools.
How we work
We care about getting the numbers right. Each tool uses standard, published formulas and exact conversion factors, and we check the results against known values before a tool goes live. Where a calculation is an estimate rather than an exact figure, the tool says so, because a clear caveat is more useful than false precision.
We also keep the site light. Tokealo respects your privacy: the values you enter are processed in your browser and are not sent to us or saved on our servers. The tools work the same on a phone as on a laptop, and they stay free to use. For the full detail on data, cookies, and advertising, see our Privacy Policy.
