What it calculates
The percentage increase calculator finds the new value after a starting value grows by a percent, or solves for the increase.
Formula
- new value = original value * (1 + increase percent / 100).
- increase amount = original value * increase percent / 100.
Inputs
- Original value.
- Increase percent.
- Or original value and new value.
Example
| Original | Increase | New value |
|---|---|---|
| 100 | 20% | 120 |
| 50 | 10% | 55 |
| 80 | 25% | 100 |
How to interpret the result
The new value includes the original value plus the increase amount. A 20% increase adds 20% of the original value.
Common mistakes
- Increasing by 20% means multiplying by 1.2, not adding 20 units.
- Consecutive increases compound step by step.
- Distinguish percent from percentage points.
