Percentage calculator for everyday questions
Work out a tip or tax (what is 15% of 80?), a test score (45 is what percent of 60?), a price rise or pay rise (from 50 to 65 is +30%), or a sale price (120 minus 25% is 90). Commas in numbers like 1,250 are fine.
Frequently asked questions
How do I calculate a percentage increase?
Subtract the old value from the new one, divide by the old value and multiply by 100. The third line of the calculator does this for you.
How do I take a discount off a price?
Use the last line: enter the price and the discount percentage to see the sale price.
