Hey Product Hunt π
I built TidyCalcs because every time I needed to run a quick number β mortgage payment, debt payoff timeline, BMI, retirement savings gap β I either hit a paywall, a forced email signup, or a calculator buried under five pop-ups.
TidyCalcs is the opposite: pick a calculator, type your numbers, get your answer immediately. No account. No email. No paywall.
What's in it right now:
Mortgage, refinance, amortization schedule, home equity, rent-vs-buy
Auto loan, personal loan, debt payoff, debt-to-income, credit card payoff
Retirement, investment, compound interest, net worth, savings goal, life insurance (DIME method)
BMI, calorie, body fat percentage (Navy method)
49 currency conversion pairs
20 in-depth guides (first-time homebuyer, refinancing, credit score basics, etc.)
It's a one-person project, still actively growing β I'd genuinely love feedback on what calculator you wish existed but can't find anywhere, or what's confusing/broken. I'll be in the comments all day.

Love that everything runs locally without an account. One thing that would be a huge help: let me save my inputs as a shareable link or PDF, especially for the mortgage and debt payoff calculators. Comparing scenarios by re-entering numbers each time is the only friction point in an otherwise super clean tool.

@bar191801Β Really appreciate that. You're right, a shareable link or PDF for saved inputs is exactly the kind of friction I want to kill next β adding it to the list, thank you!

Love that the mortgage and refi break-even calculators sit right next to each otherβthat's the exact comparison most people actually need to make, and you nailed putting them side by side without making me dig through menus.

@pnar1086289Β Thanks for noticing that β pairing the mortgage and refi break-even calculators was almost cut, glad it's actually useful in practice!
