How to Calculate Percentage
To calculate a percentage, multiply the value by the percentage and divide by 100. For example, 15% of 200 is (15 × 200) ÷ 100 = 30. To find what percentage one number is of another, divide the part by the whole and multiply by 100 — so 30 is 15% of 200. This percent calculator handles both of these cases, so you never have to do the mental math yourself.
The percentage change calculator compares two values and reports the change as a percentage. Calculate the percentage change by subtracting the original value from the new value, dividing by the original, and multiplying by 100. A positive result is a percentage increase, while a negative result is a percentage decrease — useful for price rises, discounts, tips, and growth rates.
Everyday percentage questions — how much is 20% off, what tip should I leave, what is the sales tax on this purchase, or by how much did a price rise — are all variations of these same two formulas. Enter the numbers and this percentage calculator returns the answer instantly.
