Hey Product Hunt! 👋 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 — mortgage, BMI, retirement, TDEE, grade calculator, tip splitter, and more — 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! 🙏

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.

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.

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.

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 IRS formulas get updated yearly for tax brackets and contribution limits, so a "last updated" date on each finance calculator would help me know if I'm looking at current numbers or something from last tax season.
