Hey Product Hunt! ๐
I built ProCalcTools because most calculator sites are either ad-heavy, require sign-ups, or aren't built for US-specific rules (like FLSA overtime, IRS tax brackets, or CDC BMI guidelines).
ProCalcTools has 66+ free calculators โ mortgage, BMI, retirement, TDEE, grade calculator, tip splitter, and more โ all using official US government formulas.
No account. No ads. Works offline as a PWA.
Would love your feedback on which calculator you'd find most useful! ๐
Love that there is no sign-up or ads, just opened it and tried the mortgage calculator right away. The fact that it uses official IRS and FLSA formulas is a nice touch, makes me trust the paycheck one more than most random sites.
The no sign-up, no ads approach with official IRS and CDC formulas is honestly the part that wins me over, you know. Most calculator sites are basically ad farms. Installing it as a PWA is a nice touch too.
The fact that everything runs without an account or ads is a huge plus, especially since most calculator sites are packed with popups. One thing that would make this even more useful is adding a way to save or bookmark frequently used calculators with my own custom inputs, like my mortgage rate or salary, so I am not retyping them every time.
finally something that just works without an account. tried the mortgage and overtime calculators and the results came back instantly with clean breakdowns. nice that it pulls from actual irs and flsa formulas instead of generic estimates.
Finally a calculator site that actually feels made for the US. The paycheck one with overtime built in is super handy, way nicer than digging around for that IRS formula yourself.
Used it on my phone and the mortgage calculator gave me the same number my bank quoted, which instantly sold me on it. Love that there's no sign-up nonsense either.
