Hi Product Hunt! 👋
PercentPoint started from a simple frustration: most online calculators give you a number but don't show how they got it, and many are buried under clutter. We wanted calculators you can actually trust and learn from.
So every page shows the formula, a worked example and the sources behind it. There are 68 calculators in four groups:
- Grades & GPA – weighted and college GPA, final grade, test grade
- Math & Percentages – percentage, percent change, fractions, statistics, algebra and geometry
- Business & Pricing – markup, profit margin, break-even, discount, ROAS, CPM
- Pay & Salary – salary to hourly, overtime, pay raise, time card, PTO, freelance rate
It's free, needs no sign-up, and works well on your phone.
We'd love your feedback: which calculator is missing, and did any result or explanation confuse you? Every comment helps us decide what to build next. Thanks for checking it out!
