Understanding Percentage Calculations
In our daily lives, percentages are everywhere. From calculating the tip at a restaurant to understanding your annual salary hike, percentages help us compare numbers effectively. The **Toolvala Percentage Calculator** simplifies these calculations into three easy-to-use modes.
1. Percentage Increase / Decrease
This is the most common calculation in finance and business. Whether you are tracking stock prices, inflation, or your savings growth, you need to know the *rate of change*.
The Formula: ((New Value - Old Value) / Old Value) × 100
If the result is positive, it's an Increase. If negative, it's a Decrease. Our calculator handles the math instantly.
2. Calculating Exam Marks
Students often need to convert their scored marks into a percentage to know their grade. Simply dividing your score by the total marks and multiplying by 100 gives you the exact percentage.
