Calculate Percentage Now! →The Basic Formula
At its core, finding what percent one number is of another involves a straightforward formula:
Percentage = (Part / Whole) * 100
In this formula, "Part" represents the number you're trying to express as a percentage, and "Whole" is the total or reference value.
Real-World Examples
Let's look at some common scenarios where this calculation comes in handy:
- Exam Scores: Suppose you scored 75 out of 100 on a test. What percentage did you get?
- Sales and Discounts: A store offers a $20 discount on a $100 item. What percentage discount is that?
- Budgeting: You spend $500 on rent out of a $2000 monthly income. What percentage of your income goes to rent?
These all boil down to the same question: "number is what percent of number?"
Solving Percentage Problems Step-by-Step
- Identify the "Part" and the "Whole": Determine which number represents the portion and which represents the total.
- Apply the Formula: Divide the "Part" by the "Whole".
- Multiply by 100: Convert the decimal result into a percentage.
For example, to find what percentage 30 is of 150:
- Part = 30, Whole = 150
- 30 / 150 = 0.2
- 0. 2 * 100 = 20%
Therefore, 30 is 20% of 150.
Percentage Increase and Decrease
Percentages are also useful for showing relative change, check out our percentage increase calculator.
Percentage Increase = [(New Value – Original Value) / Original Value] x 100
Percentage Decrease = [(Original Value – New Value) / Original Value] x 100
For example if a price goes from 100 to 120 then that's a 20% increase. If a price goes from 100 to 80 then that's a 20% decrease.
