Formula of Percentage Gain
Understanding the formula helps you know how the calculator works behind the scenes.
Percentage Gain Formula:
Percentage Gain=Initial ValueFinal Value−Initial Value×100
Explanation of the Formula
Let’s break it down:
- Final Value = The new or selling price
- Initial Value = The original or purchase price
- Final – Initial = Actual profit or gain
- Divide by Initial Value = Converts gain into ratio
- Multiply by 100 = Converts into percentage
Example of Percentage Gain Calculation
Let’s understand with a real-life example:
Example 1: Investment Profit
- Initial Investment = $500
- Final Value = $750
Step Calculation:
Gain = 750 – 500 = 250
Percentage Gain = (250 / 500) × 100 = 50%
Final Answer:
👉 50% Gain
Example 2: Product Price Increase
- Original Price = $200
- New Price = $260
Gain = 260 – 200 = 60
Percentage Gain = (60 / 200) × 100 = 30%
👉 30% Price Increase
Percentage Gain Table Examples
Here is a simple table to help you understand different scenarios:
| Initial Value | Final Value | Gain/Loss | Percentage Gain |
|---|---|---|---|
| 100 | 150 | +50 | 50% |
| 200 | 300 | +100 | 50% |
| 500 | 750 | +250 | 50% |
| 1000 | 1200 | +200 | 20% |
| 1500 | 1800 | +300 | 20% |
| 2000 | 2500 | +500 | 25% |
This table shows how different values can still produce the same or different percentage gains depending on the change.
