Percentage calculator helps you solve for accurate percent values in any equation. The tool utilizes basic percent formulas to determine the unknowns by providing two values in each case selected. With that, you can also add or subtract a percentage from any number within moments.

**“Percentage is defined as a number, fraction, or ratio that you can represent as a fraction of 100”**

**Symbol:** %

If you ate two slices of a pizza consisting of **8** pieces in total, you ate **25%** of pizza.

In algebra, the basic percentage equation is as under:

**P (Percentage) × \(V_1\) = \(V_2\)**

**P**represents the percentage,- \(V_1\) represents the first value that will be modified by the percentage.
- \(V_2\) is the outcome of the percentage that is functioning on \(V_1\).

Find 25 percent of 50.

**Sol:**

P× 50 = 2.5

P = 25 / 100 * 50 = 0.25 * 50 = 12.5%

The calculator above supports all percent variants that are important for you to understand. Let’s explore them one by one with respective formulas, guides, and examples!

**Y = P% * X**

- The “what” is said to be Y that you want to solve for
- First, you have to convert percentage to decimal, dividing by 100

What is 20% of 50?

**Solution:**

Y = P% * X

Y = 20% * 50

Converting percent to decimal:

Y = (20/100) * 50

Y = 0.2 * 50

Y = 10

**P% = Y ÷ X**

- The “what” is said to P% that you want to solve for
- Just divide both sides by X to obtain P% on one side of the equation
- Y ÷ X = (P% ? X) ÷ X, you get Y ÷ X = P% that is also written as: P% = Y ÷ X

15 is what percent of 60?

**Solution:**

Equation: P% = Y / X

P% = 15 / 60

P% = 0.25

Convert decimal to percent:

P% = 0.25 * 100

P% = 25%

**X = Y ÷ P%**

- The “what” is said to be X that you want to solve for
- Simply divide both sides of the equation by P% to obtain X on one side
- Y ÷ P% = (P% × X) ÷ P%, you get Y ÷ P% = X, it is also written as X = Y ÷ P%

7 is 66% of what?

**Solution:**

Equation: X = Y / P%

X = 7 / 66%

Converting percent to decimal:

X = 7 / (66 / 100)

X = 7 / 0.66

X = 10.61

**P% = Y ÷ X**

- The “what” is P% that you need to solve for
- Now, simply divide both sides of equation by X to get P% only on one side
- (P% * X) ÷ X = Y ÷ X, you get P% = Y ÷ X

What percent of 25 is 7?

**Solution:**

P% = Y / X

P% = 7 / 25

P% = 0.28

Convert decimal to percent:

P% = 0.28 * 100

P% = 28%

**X = Y ÷ P%**

- The “what” is indicated as X that you need to solve for
- Now, all you need to divide both sides of the equation by P% to get X on one side
- (P% × X) ÷ P% = Y ÷ P%, you get: X = Y ÷ P%

30% of what is 9?

**Solution:**

Equation: X = Y / P%

X = 9 / 30%

Converting percent to decimal:

X = 9 / (30 / 100)

X = 9 / 0.3

X = 30

**Y = P% * X**

- In terms of the equation, it is written as P% * X = Y
- The “what” is said to be Y that you need to solve for

7% of 27 is what?

**Solution:**

Equation: Y = P% * X

Y = 7% * 27

Converting percent to decimal:

Y = (7 / 100) * 27

Y = 0.07 * 27

Y = 1.89

**X = Y ÷ P%**

- The “what” is expressed as X that you need to solve for
- Multiply simply both sides of the equation by X to obtain X out of the denominator
- (Y / X) * X = P% * X, you get: Y = P% * X
- Now, simply divide both sides of the equation by P% to get X on one side
- Y ÷ P% = (P% * X) ÷ P%, you get: Y ÷ P% = X

5 of what is 13%?

**Solution:**

X = Y / P%

X = 5 / 13%

Converting percent to decimal:

X = 5 / (13 / 100)

X = 5 / 0.13

X = 38.46

**Y = P% * X**

- The “what” is said to be as Y that you need to solve for
- Now, simply multiply both sides of the equation by X to get Y on one side
- (Y ÷ X) * X = P% * X, you get: Y = P% * X

What of 26 is 12%?

**Solution:**

Y = P% * X

Y = 12% * 26

Converting percent to decimal:

Y = (12 / 100) * 26

Y = 0.12 * 26

Y = 3.12

P% = Y / X

- The “what” is the P% that you need to solve for
- Simply, solve for P% by using the formula for %

8 of 12 is what percent?

Solution:

P% = Y / X

P% = 8 / 12

P% = 0.66666666666667

Convert decimal to percent:

P% = (0.66666666666667) * 100

P% = 66.67%

The following formula supports percent difference calculations:

**Percentage Difference = |\(V_1\) – \(V_2\)| / {(\(V_1\) + \(V_2\)}/2**

Where;

- |\(V_1\) – \(V_2\)| = Absolute value of the difference between the numbers given
- \(V_1\) + \(V_2\) = Average of Numbers

The concept of percentage difference is also used to

In everyday matters, percentages serve the purpose of financial aspects understanding. Moreover, you can use percent values to compare two or more quantities at the same time.

- To convert percent to decimal, divide it by
**100** - To do reverse calculations, multiply the number by
**100**

The above calculator supports this conversion for any number or percent value entered in it.
