Hi Product Hunt!
I found Online Percentage Calculator because I kept running into the same problem — needing a quick percentage calculation and having to either remember a formula or open a spreadsheet just for one number.
Most calculators online only do one type of percentage. This one handles all 6 common scenarios in one place:
What is X% of Y?
X is what % of Y?
Percentage increase / decrease
Reverse percentage (find original price before a discount)
Percentage difference between two values
X is Y% of what?
No sign-up. No app to install. Works on any device. Just type the numbers and the answer appears instantly.
