## Percent Change Calculator

Percent change represents the degree of change over time, indicating growth or decay.

#### Key Formula

$\text{Percent Change} = \left( \frac{\text{Final Value} - \text{Initial Value}}{\text{Initial Value}} \right) \times 100\%$

#### How to Use the Percent Change Calculator

Input initial and final values to compute the percent change automatically.

#### Applications

Used in finance, medicine, business, and academic research for analyzing data changes.

1. How Do You Calculate the Percent Change?

Subtract the initial value from the final value, divide by the initial value, and multiply by 100.

2. What is the Percent Change from 4/5 to 3/5?

$$\left( \frac{3/5 - 4/5}{4/5} \right) \times 100\% = -25\%$$ (a decrease).

3. Percent Change from 36 to 99?

$$\left( \frac{99 - 36}{36} \right) \times 100\%$$ (an increase).

4. What is 20% out of 45?

20% of 45 is calculated as $$0.20 \times 45 = 9$$.

5. Why Do We Calculate Percentage Change?

To understand the relative change between two values over time.

6. Percentage Change when 25 is Increased to 45?

$$\left( \frac{45 - 25}{25} \right) \times 100\% = 80\%$$ increase.

7. What Percentage is 3 of 5?

$$\frac{3}{5} \times 100\% = 60\%$$.

8. Percent Change from 4 to 5?

$$\left( \frac{5 - 4}{4} \right) \times 100\% = 25\%$$ increase.

9. Percent Change from 64 to 80?

$$\left( \frac{80 - 64}{64} \right) \times 100\%$$ (an increase).

10. Percentage Change from 80 to 100?

$$\left( \frac{100 - 80}{80} \right) \times 100\%$$ (an increase).

11. Percent Change from 70 to 98?

$$\left( \frac{98 - 70}{70} \right) \times 100\%$$ (an increase).
