Formula of Adding & Subtracting Percentages Calculator
Adding Percentages
- Determine the original value: Let the original value be O.
- Calculate the percentage to be add: Let the percentage to be add be P%.
- Convert the percentage to a decimal: Decimal form of P% = P / 100.
- Calculate the amount to be add: Amount to be add = O * (P / 100).
- Calculate the new value: New Value = O + (O * (P / 100)).
Subtracting Percentages
- Determine the original value: Let the original value be O.
- Calculate the percentage to be subtract: Let the percentage to be subtract be P%.
- Convert the percentage to a decimal: Decimal form of P% = P / 100.
- Calculate the amount to be subtract: Amount to be subtract = O * (P / 100).
- Calculate the new value: New Value = O – (O * (P / 100)).
Table for General Terms
The following table includes key terms related to the process of adding and subtracting percentages, making it easier for users to understand and utilize the calculator without needing to perform calculations manually:
| Term | Definition |

Example of Adding & Subtracting Percentages Calculator
Imagine a store item priced at $200. The store plans to increase the price by 20% during a seasonal sale and later reduce the new price by 10% as a promotion.
- Adding 20%: New Price = 200 + (200 * 20 / 100) = 240
- Subtracting 10% from the new price: Final Price = 240 – (240 * 10 / 100) = 216
This example illustrates how the calculator can be apply in practical retail scenarios to adjust prices dynamically.
