How to Calculate Percentages
There are many formulas for percentage problems. You can think of the most basic as X/Y = P x 100. The formulas below are all mathematical variations of this formula.
Let's explore the three basic percentage problems. X and Y are numbers and P is the percentage:
- Find P percent of X
- Find what percent of X is Y
- Find X if P percent of it is Y
Read on to learn more about how to figure percentages.
1. How to calculate percentage of a number. Use the percentage formula: P% * X = Y
Example: What is 10% of 150?
- Convert the problem to an equation using the percentage formula: P% * X = Y
- P is 10%, X is 150, so the equation is 10% * 150 = Y
- Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10
- Substitute 0.10 for 10% in the equation: 10% * 150 = Y becomes 0.10 * 150 = Y
- Do the math: 0.10 * 150 = 15
- Y = 15
- So 10% of 150 is 15
- Double check your answer with the original question: What is 10% of 150? Multiply 0.10 * 150 = 15
2. How to find what percent of X is Y. Use the percentage formula: Y/X = P%
Example: What percent of 60 is 12?
- Convert the problem to an equation using the percentage formula: Y/X = P%
- X is 60, Y is 12, so the equation is 12/60 = P%
- Do the math: 12/60 = 0.20
- Important! The result will always be in decimal form, not percentage form. You need to multiply the result by 100 to get the percentage.
- Converting 0.20 to a percent: 0.20 * 100 = 20%
- So 20% of 60 is 12.
- Double check your answer with the original question: What percent of 60 is 12? 12/60 = 0.20, and multiplying by 100 to get percentage, 0.20 * 100 = 20%
3. How to find X if P percent of it is Y. Use the percentage formula Y/P% = X
Example: 25 is 20% of what number?
- Convert the problem to an equation using the percentage formula: Y/P% = X
- Y is 25, P% is 20, so the equation is 25/20% = X
- Convert the percentage to a decimal by dividing by 100.
- Converting 20% to a decimal: 20/100 = 0.20
- Substitute 0.20 for 20% in the equation: 25/0.20 = X
- Do the math: 25/0.20 = X
- X = 125
- So 25 is 20% of 125
- Double check your answer with the original question: 25 is 20% of what number? 25/0.20 = 125
Remember: How to convert a percentage to a decimal
- Remove the percentage sign and divide by 100
- 15.6% = 15.6/100 = 0.156
Remember: How to convert a decimal to a percentage
- Multiply by 100 and add a percentage sign
- 0.876 = 0.876 * 100 = 87.6%
Percentage Problems
There are nine variations on the three basic problems involving percentages. See if you can match your problem to one of the samples below. The problem formats match the input fields in the calculator above. Formulas and examples are included.
What is P percent of X?
- Written as an equation: Y = P% * X
- The 'what' is Y that we want to solve for
- Remember to first convert percentage to decimal, dividing by 100
- Solution: Solve for Y using the percentage formula
Y = P% * X
Example: What is 10% of 25?
- Written using the percentage formula: Y = 10% * 25

Y is what percent of X?
- Written as an equation: Y = P% ? X
- The 'what' is P% that we want to solve for
- Divide both sides by X to get P% on one side of the equation
- Y ÷ X = (P% ? X) ÷ X becomes Y ÷ X = P%, which is the same as P% = Y ÷ X
- Solution: Solve for P% using the percentage formula
P% = Y ÷ X
Example: 12 is what percent of 40?
- Written using the formula: P% = 12 ÷ 40
- P% = 12 ÷ 40 = 0.3

Stamp Market Tips by Henry Gitner and Rick Miller
The Canal Zone, a strip of territory across the Isthmus of Panama on either side of the Panama Canal, was under the administration of the United States from 1904 to 1979. And from 1979 to 1999, it was jointly administered by the United States and Panama. At the end of 1999, it reverted to Panama.
The Canal Zone issued postage stamps and operated a postal service under the administration of the United States from 1904 to 1979. These Canal Zone stamps are popular with many U.S. collectors.
Demand is strong for the 1931 yellow green 15¢-on-1¢ Maj. Gen. William Crawford Gorgas airmail stamp with the type II overprint (Scott C2). As illustrated in the Scott Specialized Catalogue of United States Stamps and Covers, the flag of the '5' in the overprint is curved upward.
The Scott U.S. Specialized catalog values the stamp at $60 in unused, hinged condition and $120 in mint, never-hinged condition.
3 6 Calculator
The stamp in very fine grade is selling for about 90 percent of catalog value in unused, hinged condition.
It is a good buy in mint, never-hinged condition at 75 percent or perhaps a bit more of catalog value.
