How to Calculate a Percentage?

Calculating percentages is simple with the formula:
Percentage = (Part / Whole) × 100

Example: If you scored 45 out of 60 on a test:
(45 ÷ 60) × 100 = 75%

How do you Calculate Percentage of Increase?

To find a percentage increase:

Subtract the old value from the new value.

Divide the result by the old value.

Multiply by 100.

Formula:
% Increase = [(New Value – Old Value) / Old Value] × 100

Example: If a product’s price rises from $50 to $70:
[(70 – 50) / 50] × 100 = 40% increase

1. Subtract the New Value from the Old Value
2. Difference=Old Value−New Value
3. Difference=Old Value−New Value
4. Divide the Difference by the Old Value
5. Decimal Result=DifferenceOld Value
6. Decimal Result=
7. Old Value
8. Difference​
