Hi Product Hunt 👋

I wanted financial calculators that just work: fast, precise to the cent, private, and free — no sign-up, no paywall. So I built Numveo.

It's 200+ free US financial calculators — mortgage, loans, taxes, retirement, investing, credit cards, real estate — all running on a single engine that uses exact decimal math, so results are correct to the cent.

A few things I cared about:

• Free — no sign-up, no paywall, no limits. It's ad-supported, and I never sell your data

• Private — the calculations run in your browser; nothing you type is sent to a server, and most calculators work fully offline

• Sourced & dated — tax and benefit figures are checked against IRS / SSA / CFPB, with the tax year shown on every page

• Plain-English Learn guides + a glossary, so the numbers actually make sense

👉 Try it on the web: https://numveo.com

📱 Android app (same calculators, fully offline): https://play.google.com/store/apps/details?id=com.numveo.app

I'd genuinely love your feedback: which calculator is missing, and what would make Numveo more useful to you? Happy to answer anything — thanks for checking it out 🙏

Love that everything runs locally with exact decimal math, that fixes so many rounding issues I've hit on other sites. One idea: let users save scenarios or inputs to compare side by side, maybe via an exportable JSON or a local bookmark, since right now refreshing the page wipes everything.
