NimbleCalc
52 free online calculators — no sign-up, no paywalls
52 free online calculators covering finance, health, math, construction, and business. No sign-up, no paywall, no data sent to servers — everything runs in your browser. Fast, private, and free forever.
Hey Product Hunt! 👋 Vijay here, maker of NimbleCalc.
I built this because every time I searched for a quick calculator online, I'd land on a site that made me scroll past ads, sign up for an account, or hit a paywall just to see a result. That's frustrating when you just need a number.
NimbleCalc fixes that — 52 calculators, open instantly, no account, no paywall, everything runs in your browser so your data never leaves your device.
A few calculators I'm particularly proud of:
- **Mortgage Calculator** — shows full amortization schedule month by month
- **Compound Interest** — visualizes how your savings grow over time
- **Debt Payoff** — compares avalanche vs snowball methods side by side
- **Concrete Calculator** — saves contractors from buying too many (or too few) bags
Would love your feedback — what calculator do you wish existed that isn't here yet? I'm actively expanding the library and your suggestions will directly shape what gets built next.
Thanks for checking it out! 🙏
