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.
@gunnar_wan Thank you — that's the exact itch I built Numveo to scratch, so it means a lot that the decimal-precision lands for you 🙏
And you're spot on about persistence: right now a refresh wipes your inputs, which is annoying the second you want to weigh two options. Saving and comparing scenarios is high on my list.
I really like your JSON/bookmark angle because it keeps the privacy promise intact — I'm leaning toward encoding the inputs in a shareable URL (bookmark it, or send a scenario to someone, no account needed) plus a local "saved scenarios" list, with a side-by-side compare view on top.
Small note in the meantime: each calculator already has Save-PDF / CSV / Copy / Share — but that's a snapshot, not a reusable scenario, which is exactly the gap you're pointing at.
Genuinely appreciate the thoughtful feedback. If you had it today, which would you reach for first — bookmarkable URLs, or the side-by-side compare?
