Hello Product Hunt
I've built Worldculator because I kept finding calculator sites that were either covered in ads, required an account, or gave you a result with zero explanation.
My goal is very simple : all calculator's should work instantly, explaining what it's doing, and completely free with no catches.
Currently covering finance (mortgage, 401k, net worth, tip), health (BMI, BAC, pregnancy weight gain), math (everything from percentages to quadratic equations), construction (concrete, shed base, gravel), social media (account value, engagement rate, ad budgets) and a lot more.
Would love to know which calculators you'd want to see added ? happy to build any that are missing.
