Finance Calc Kit is a free library of 697 calculators across 19 categories - loans, mortgages, tax, retirement, savings, investments, paycheck and currency. Every calculator runs in the browser, shows the formula it uses and cites independent references, so a result can be checked instead of trusted. No account, no paywall, no stored inputs; a scenario can be encoded in a URL and shared.

I kept finding calculator sites that showed a number with no working and asked for an email before the result. Finance Calc Kit is my answer: 697 calculators across 19 categories, every one running client-side, printing the formula it used with references, and keeping the inputs on your device. Free, no account.
Happy to answer anything about the formulas, the coverage, or what to add next.
