SupaCalc - 100+ Free Online Calculators
113 free calculators for AI spend, GLP-1 costs & modern life
Hey Product Hunt 👋
I started SupaCalc in 2020 as a side project because I got tired of calculator sites that felt stuck in 2010 — slow, ad-choked, and missing the tools I actually needed.
Five years later, we're relaunching with 113 calculators. Some are classics (mortgage, BMI, compound interest). But the ones I'm proudest of are the ones nobody else has built well:
→ AI Token Cost Calculator — know your API bill before you get the invoice
→ Vibe Coding Cost Calculator — Claude + Cursor + ChatGPT + Copilot adds up fast
→ GLP-1 Cost Calculator — Ozempic/Wegovy/Mounjaro with and without insurance
→ True Cost of Subscriptions — the $847/month you didn't know you were spending
→ Financial Independence Calculator — Lean FI, Standard FI, Fat FI targets
Everything is free. No signup. Calculations run in your browser so your data never touches our servers.
We also just opened a free embed program — grab any calculator as an iframe for your blog or site, no API key needed.
Would genuinely love feedback on what's missing. What calculator do you wish existed?
