Percentage Calculator
1. Find What Percentage One Number is of Another
Question: What percentage of X is Y?
Use this to : Determine the proportion of one value (Y, the part) in relation to another value (X, the whole), expressed as a percentage. For example, if you scored 10 points out of a possible 50, what percentage did you achieve?
Enter values above
2. Calculate Percentage of a Number
Question: What is Percentage X of Number Y?
Use this to: Find a specific percentage (X%) of a given number (Y). This is useful for calculating discounts, sales tax, or tips. For example, what is 20% of £150?
Enter values above
3. Find the Original Number Given a Percentage
Question: Number X is Percentage Y of what original number?
Use this to: Work backwards to find the whole amount when you know a part (X) and what percentage (Y%) that part represents. For example, if £30 is 25% of the original price, what was the original price?
Enter values above
4. Calculate Percentage Increase
Question: What is the percentage increase from Start Value X to End Value Y?
Use this to: Determine how much a value has increased from an original amount (X) to a new, higher amount (Y), expressed as a percentage. For example, if your rent went from £100 to £120, what was the percentage increase?
Enter values above
5. Calculate Percentage Decrease
Question: What is the percentage decrease from Start Value X to End Value Y?
Use this to: Determine how much a value has decreased from an original amount (X) to a new, lower amount (Y), expressed as a percentage. For example, if a price dropped from £100 to £80, what was the percentage decrease?
Enter values above
6. Increase a Number by a Percentage
Question: What is Number X increased by Percentage Y?
Use this to: Calculate the new value after increasing an original number (X) by a specific percentage (Y%). For example, what is £200 increased by 15%?
Enter values above
7. Decrease a Number by a Percentage
Question: What is Number X decreased by Percentage Y?
Use this to: Calculate the new value after decreasing an original number (X) by a specific percentage (Y%). For example, what is £200 decreased by 15%?
Enter values above
8. Convert Percentage to Fraction
Question: What fraction is Percentage X equivalent to?
Use this to: Express a given percentage (X%) as a simplified fraction. For example, what is 75% as a fraction?
Enter value above
9. Convert Fraction to Percentage
Question: What is Numerator X / Denominator Y as a percentage?
Use this to: Convert a fraction (X/Y) into its equivalent percentage. For example, what is 3/4 as a percentage?
Enter values above
10. Calculate Percentage Difference
Question: What is the percentage difference between Value X and Value Y?
Use this to: Find the difference between two numbers (X and Y) as a percentage of their average. This is useful for comparing two values where neither is explicitly the “original” or “new” value.
Enter values above
11. X is What Percent More Than Y?
Question: Value X is what percentage more than Value Y?
Use this to: Calculate how much larger one value (X) is compared to another value (Y), expressed as a percentage relative to Y. For example, if X is 120 and Y is 100, X is what percent more than Y?
Enter values above
12. X is What Percent Less Than Y?
Question: Value X is what percentage less than Value Y?
Use this to: Calculate how much smaller one value (X) is compared to another value (Y), expressed as a percentage relative to Y. For example, if X is 80 and Y is 100, X is what percent less than Y?
Enter values above
