Everything you need to know about percentage calculations
To calculate a percentage, divide the part by the whole and multiply by 100. For example, if you scored 85 out of 100, the percentage is (85 ÷ 100) × 100 = 85%.
To calculate percentage increase, find the difference between new and old values, divide by the old value, and multiply by 100. Formula: ((New Value - Old Value) / Old Value) × 100.
Percentage increase shows how much a value has grown, while percentage decrease shows how much it has reduced. Both use the original value as the base for comparison.
Yes, percentages can exceed 100%. For example, if something doubles in value, that's a 100% increase. If it triples, that's a 200% increase.
To add a percentage, multiply the number by (1 + percentage/100). To subtract, multiply by (1 - percentage/100). For example, adding 20% to 100: 100 × (1 + 20/100) = 120.
