Calculate Percentages Now! →The Basic Formula
The core formula for calculating percentages is:
Percentage = (Part / Whole) x 100
Let's break down how this applies to different scenarios.
Scenario 1: What Percentage is One Number of Another?
This is perhaps the most common use case. Imagine you scored 75 points on a test that was worth 100 points total. What's your percentage score?
- Identify the "part" and the "whole." In this case, your score (75) is the part, and the total possible score (100) is the whole.
- Apply the formula: Percentage = (75 / 100) x 100
- Calculate: 0.75 x 100 = 75%
- Therefore, you scored 75% on the test.
Quick Tip: Simplify the fraction (Part / Whole) before multiplying by 100. It can make the calculation easier!
Scenario 2: Percentage Increase or Decrease
Often, you'll want to know the percentage change between two values. For example, if a product's price increased from $20 to $25, what's the percentage increase?
- Find the difference: Subtract the original value from the new value. In this case, $25 - $20 = $5. This is the "increase amount".
- Divide by the original value: $5 / $20 = 0.25
- Multiply by 100: 0.25 x 100 = 25%
- Therefore, the price increased by 25%.
The formula for percentage decrease is similar; just make sure the difference is calculated as (Original Value - New Value).
Scenario 3: Finding the Original Value
Sometimes, you know a percentage and the resulting value, but you need to find the original value. For example, a store offers a 20% discount, and an item is now selling for $80. What was the original price?
- Understand the remaining percentage: If there's a 20% discount, the selling price represents 80% of the original price (100% - 20% = 80%).
- Convert the percentage to a decimal: 80% = 0.80
- Divide the result by the decimal: $80 / 0.80 = $100
- Therefore, the original price was $100.
