The tool works seamlessly by allowing users to enter two known values to find the third.

Percent Decrease Formula

\text{Percent Decrease} = \left( \frac{\text{Initial Value} – \text{Final Value}}{\text{Initial Value}} \right) \times 100

Alternative Formulas

Initial Value

\text{Initial Value} = \frac{\text{Final Value}}{1 – \left(\frac{\text{Percent Decrease}}{100}\right)}

Final Value

\text{Final Value} = \text{Initial Value} – \left(\text{Initial Value} \times \frac{\text{Percent Decrease}}{100}\right)

Variable	Description	Example Unit
Initial Value ($)	The starting value before the decrease	Dollars ($)
Final Value ($)	The value after the decrease	Dollars ($)
Percent Decrease (%)	The percentage reduction between the values	Percentage (%)
