MoneyCrunchLab
25 free calculators - your numbers never leave your browser
Free interactive calculators for mortgages, debt payoff, savings, and retirement. Every tool runs entirely in your browser (your numbers never leave it), states its assumptions next to the results, and can be embedded on any website with one line of HTML.
I built MoneyCrunchLab after noticing that most financial calculators online are either ad-walled quiz funnels or worked examples with someone else's numbers.
So I made 25 interactive calculators (mortgages, debt payoff, savings, retirement) with a few stubborn design constraints:
• Everything computes in your browser — the numbers you type never leave it. No sign-up, no account. • Every calculator states its assumptions next to the results, and shows the losing side of a trade-off when there is one (rent-vs-buy will happily tell you renting wins). • Each tool can be embedded on any site with one line of HTML, free, with no ads inside the widget. • The math is verified against closed-form financial formulas before publication.
If you find a number that looks wrong, tell me — I'll show the math or fix it. Happy to answer anything!
