Percentage Increase Calculator
Calculate the new value after applying a percentage increase: price hikes, salary raises, or any other increase.
How is it calculated?
Increase = original value × percentage ÷ 100. New value = original value + increase.
Examples
A value of 1,200 with a 5% increase
The value goes up 60 to 1,260.
A value of 800 with a 12.5% increase
The value goes up 100 to 900.
How a percentage increase is calculated
The new value is the original × (1 + percentage ÷ 100). Increasing 1,200 by 5% is 1,200 × 1.05 = 1,260.
The increase amount is the difference (60 in the example). A negative percentage calculates a decrease; for price markdowns, the discount calculator is more direct.
How to find the percentage change between two values
Notice that a 20% increase and a 20% decrease don't cancel out: 100 → 120 → 96. For any other percentage question, check the percentage calculator or the rule of three.
| Situation | Formula | Example |
|---|---|---|
| Percentage change | (New − Original) ÷ Original × 100 | 50 to 60 = +20% |
| Percentage decrease | (Original − New) ÷ Original × 100 | 60 to 50 = −16.7% |
| Original value from the new one | New ÷ (1 + increase) | 1,260 with +5% → 1,200 |
