What is a percentage calculator?
A percentage calculator handles the small bits of maths that come up constantly but are just annoying enough to want a tool for: working out a tip or a discount, checking what percent of a budget you've spent, figuring a grade, or seeing how much a price changed. The four core questions cover almost everything — what is X% of a number, what percent one number is of another, the percentage change between two values, and a number increased or decreased by a percent. It's among the most-searched calculators on the web precisely because the formulas are easy to forget and easy to get backwards. A good one states each question in plain language, fills in the answer as you type, and is careful about the edge cases — dividing by zero, negative changes, values over 100% — instead of quietly showing a wrong or broken result.
Common features
- What is X% of a number
- X is what percent of Y
- Percentage change between two values (up or down)
- Increase and decrease a value by a percent
- Plain-language, fill-in-the-blank layout
- Live results as you type
- Up/down direction shown for changes
- Safe handling of divide-by-zero (shows a dash)
- Copy any result; everything client-side
- Light and dark themes; inputs remembered
Real-world examples
A discount
Someone works out 25% off a $80 item by reading the 'decreased by' result — $60 — without reaching for a separate calculator.
A grade
A student types 'what percent is 46 of 60' and gets 76.6667% instantly.
A price change
A shopper checks the percentage change from $50 to $75 and sees a green ↑ 50% — and from $100 to $80, a red ↓ 20%.

Build a percentage calculator with plain-language cards. Card 1: 'What is P% of N?' Card 2: 'X is what percent of Y?' Card 3: 'Percentage change from A to B?' with an up/down arrow and colour. Card 4: a value increased and decreased by P%, showing both. Inline number inputs inside the sentences, results that update live, and a copy button on each. Guard against dividing by zero (show a dash). Keep it deterministic so the first render is hydration-safe, and remember every input in localStorage. 100% client-side.
Create a percentage calculator like the popular ones: type two numbers and get the percent. Cover 'what is X% of Y', 'X is what % of Y', and percentage increase/decrease. Keep it in the browser.
Build a friendly percent calculator for everyday maths — discounts, tips, grade percentages, percentage change — with a clean card layout and a dark theme.
