How does Our Tool Calculate Percentages?

Certainly, there are multiple ways to write percentage formulas, but they are mainly algebraic equations that involve three values:

P × V1 = V2,

Where P denotes Percentage, V1 is the first value modified by percentage, and V2 is the resultant value taken by percentage calculation on V1.

Our free percentage calculator uses the above formula to calculate the percentage of a value by converting the input percentage into a decimal to calculate the given solution.

If you want to solve the equation manually, the percentage formula will require the percentage in decimal form. It denotes that the result needs to be multiplied by 100 to convert it into a percentage value. That is what our calculator does, and it accepts inputs in percent and decimal form.

Understanding Percentage Formula

Percentage problems can be solved through different formulas. The easiest and most used formula for calculating the percentage is X/Y = P x 100.

To understand the working of this formula, let’s take assistance from an example. In the following example, X and Y are the numbers where P is the percentage.

Problem: What is 20% of 100?

Solution: In this problem,

P= 20%


So, the equation will be: 20% * 100 = Y

We will start by converting 20% to a decimal by eliminating the percentage sign and dividing by 100, i.e: 20/100 = 0.20

Now, substitute 0.2 for 20% in the equation:

20% * 10 = Y becomes 0.20 * 100 = Y

Calculate the value: 0.20 * 100 = 20

Y = 20

Hence, 20% of 100 is 20.

Percentage Conversion Examples

Below are a few other examples of calculating percentages that can help you better understand the process.

Example 1:

Problem: 15 is 30% of what?

Solution: In this equation, Y = 15

P = 30%

So, the equation will be 15/30% = X

First, convert the percentage value to a decimal number by dividing it by 100.

30% into decimal: 30/100= 0.30

Now, Substitute this decimal value in the equation.

15/0.30 = X

Calculate the Value: 15/0.30 = X ; 50 = X

X = 50


Answer:The 15 is 30% of 50.

Example 2:

Problem: 18 is what percent of 78?

Solution: The formula for finding percentage: P% = Y / X


18/78 = P% Or, P% = 18/78

18/78 = 0.2307

Now, convert decimal value to a percentage value by multiplying it by 100

0.2307 * 100 = 23.08%

18/78 = 23.08%


Answer: The 18 is 23.08% of 78.

Example 3:

Problem: What is 80% of 2950?


Add values in the percentage formula (P% = Y / X)

So; it will become:

Y= 80% * 2950

Now, convert the percentage value into the decimal by dividing it by 100: 80/100 = 0.80

Enter the decimal value in the equation: Y = 0.80 * 2950

Y = 2360


Answer: 80% of 2950 is 2360.
