Example Scenarios

Example 1: If you invest $1,000 and it increases by 15% annually, what will be the final value after one year?

Initial Value: $1,000
Percentage Change: +15%
Final Value: $1,150

Example 2: If a product costs $50 and there's a 20% discount, what is the final price?

Initial Value: $50
Percentage Change: -20%
Final Value: $40

Mathematical Principle

This calculator uses the formula: Final Value = Initial Value × (1 + Percentage Change / 100)

For example, a 10% increase would be calculated as: Final Value = Initial Value × (1 + 10/100) = Initial Value × 1.10
