29 free browser-side calculators for finance, health and everyday math, each showing its formula and a worked example.
Miryori is a free suite of 29 browser-based calculators covering three areas.
Personal finance: APY versus APR, compound interest and savings goals, loan and mortgage amortization schedules, salary and hourly pay, overtime and PTO accrual.
Health: BMI, BMR, body fat percentage, calorie targets and running pace.
Utility: unit conversions, date and age arithmetic, Roman numerals and password generation.
Every tool runs entirely client-side. There is no account, no email gate and no server-side log, so salary figures, loan balances and body measurements stay in the browser tab. The calculators are static pages that work offline after the first load and install as a PWA.
Each calculator shows the formula in plain notation beneath the result and includes a worked example a reader can reproduce by hand. The APY page, for instance, displays APY = (1 + r/n)^n - 1 and walks a 5% nominal rate compounded monthly to 5.116%. Every page also carries a short usage guide, common mistakes, a FAQ and links to related tools.
The interface is available in nine languages: English, Spanish, German, French, Portuguese, Japanese, Arabic, Korean and Simplified Chinese.
