Calculate Percentages Instantly! →Understanding the Basics of Percentage Calculations
Percentages are all around us, representing a part of a whole. Here's a quick review of the three main types of percentage problems you'll likely encounter:
- Finding a percentage of a number: What is 15% of 200?
- Determining what percentage one number is of another: 30 is what percent of 150?
- Calculating percentage increase or decrease: Going from 80 to 100 is what percentage increase?
Solving Percentage Problems with a Basic Calculator
While a dedicated percentage calculator is often the quickest way, you can also solve these problems using a standard calculator with a few simple steps.
1. Finding a Percentage of a Number
To find X% of Y, multiply X by Y, then divide by 100. For example, to find 25% of 80:
- Enter 25
- Press the multiplication key (*)
- Enter 80
- Press the equals key (=)
- Divide the result by 100
The answer is 20.
2. Determining What Percentage One Number Is of Another
To find what percentage X is of Y, divide X by Y, then multiply by 100. For example, to find what percentage 40 is of 200:
- Enter 40
- Press the division key (/)
- Enter 200
- Press the equals key (=)
- Multiply the result by 100
The answer is 20%.
3. Calculating Percentage Increase or Decrease
To calculate the percentage change from an old value (OV) to a new value (NV):
- Subtract the old value from the new value: (NV - OV)
- Divide the result by the old value: (NV - OV) / OV
- Multiply the result by 100.
For example, if a price increases from $50 to $60:
- 60 - 50 = 10
- 10 / 50 = 0.2
- 0.2 * 100 = 20%
The price increased by 20%.
