## How to calculate percentage change?

**Example:-If a population in 2020 is 1250056 and 1265685 in 2021 then find what percentage change of population?**

- Population in 2020 = 1250056; let x1
- Population in 2021 = 1265685; let x2
- Population increase in 2021 = [(x2 – x1) / x1] * 100
- % change = (1250056 – 1265685) / 12565685 * 100
- % change = ( 15629 ) / 1265685 * 100
- % change of population = + 1.25%
- 1.250% increase in population in 2021.

**Example:-A person who has a salary is $5000 after an increment of salary is $5650 then find what percentage change of his salary?**

- After increament of his salary = $5650; let z2
- Percentage change of his salary = (Z2 – Z1) / Z1 * 100
- % change = (5650 – 5000) / 5000 * 100
- % change = ( 650 ) / 5000 * 100
- % increase = + 13%
- 13% increase of his salary after the increment.
