Percentage Calculator
Enter a percentage and a number — the result appears instantly. Used daily for calculating VAT on invoices, tips on restaurant bills, commission on sales, and percentage shares of a budget. One thing worth knowing: this gives you a specific amount, not a rate or ratio — if you need to express one number as a percentage of another, that's a different calculation. If you know the result but not the original, the reverse percentage calculator handles that.
When to use this calculator
Use this when you have a percentage and a number and need to find the actual amount — for example, 18% of $240, 5% of 1,800, or 12.5% of a $50,000 budget. It covers any situation where you're applying a rate to a base value.

FAQ
What is 25% of 80?
25% of 80 is 20. Calculation: (25 / 100) × 80 = 20. A quick shortcut: 25% is always a quarter, so divide the number by 4.
What is 10% of 350?
10% of 350 is 35. To find 10% of any number, move the decimal one place left. From there, multiply or divide to reach any other percentage — 5% is half of that (17.5), 20% is double (70).
What is 1% of a large number?
1% is always the number divided by 100. So 1% of 8,500 is 85. Multiply by any whole number to reach other percentages: 7% of 8,500 = 85 × 7 = 595.
Can I enter decimal percentages like 12.5%?
Yes. Enter 12.5 in the percentage field. Useful for 6.5% tax rates, 2.75% savings interest, or any non-round rate.
What is the difference between percent and percentage points?
Percent expresses a ratio (20% of 100 = 20). Percentage points measure the arithmetic difference between two percentages — if an interest rate rises from 3% to 5%, that's a 2 percentage-point rise. As a percentage change, it's actually a 66.7% increase.
I know the result but not the original — what do I do?
If you know the result and the percentage, but need the original number, use the reverse percentage calculator. For example: 30 is the result of applying 15% to some number — the answer is 200.
