Calculate the percentage increase or decrease between two values, along with absolute difference and growth multipliers.
| Original Value | New Value | Formula Applied | Percentage Increase |
|---|---|---|---|
| $50 | $75 | ((75 - 50) / 50) × 100 | +50% |
| 80 | 100 | ((100 - 80) / 80) × 100 | +25% |
| $200 | $250 | ((250 - 200) / 200) × 100 | +25% |

Student ProjectHi! I'm a student developer building Calculat in my spare time. I was tired of searching for basic math tools and having to click through 10 spammy popups, loan ads, and cookie trackers.

A percentage increase calculator measures the relative change between an initial starting value and a subsequent final value. It is widely used in economics, finance, salary benchmarking, and scientific measurements to quantify growth or contraction.
\Delta\% = \left( \frac{\text{Final} - \text{Initial}}{|\text{Initial}|} \right) \times 100Subtract the initial value from the final value to find the absolute difference, divide that difference by the absolute initial value, and multiply by 100.
Scenario: A company had 50 employees in 2024 and 75 employees in 2025.
Calculate the difference: 75 - 50 = 25.
Divide by the initial count: 25 / 50 = 0.50.
Multiply by 100: 0.50 × 100 = 50% increase.
Subtract 40 from 50 (difference = 10). Divide 10 by 40 (0.25). Multiply by 100 to get a 25% increase.
A 100% increase means adding 100% of the initial number to itself, which results in exactly twice the starting value (2x multiplier).
