Find Rate Percentage Now →Understanding the Basics
Before diving into the methods, it's important to understand what the "rate percentage" represents. Essentially, you're trying to find out what percentage one number is of another. This often arises in situations like calculating what portion of a budget is allocated to a specific expense, or determining the percentage increase or decrease in sales figures.
The Formula for Finding the Rate Percentage
The core formula you'll use is:
(Part / Whole) x 100 = Rate Percentage
- Part: The specific amount or value you're interested in.
- Whole: The total amount or value that the "part" belongs to.
Step-by-Step Examples
Example 1: Calculating Percentage of a Number
Problem: What percentage of 150 is 30?
- Identify the "Part" and "Whole": In this case, 30 is the "Part," and 150 is the "Whole."
- Apply the Formula: (30 / 150) x 100
- Calculate: 0.2 x 100 = 20%
Answer: 30 is 20% of 150.

Example 2: Finding Percentage Increase
Problem: A price increased from $80 to $100. What is the percentage increase?
- Calculate the Increase: $100 - $80 = $20
- Identify the "Part" and "Whole": The increase ($20) is the "Part," and the original price ($80) is the "Whole."
- Apply the Formula: (20 / 80) x 100
- Calculate: 0.25 x 100 = 25%
Answer: The price increased by 25%.

Example 3: Calculating Percentage Decrease
Problem: Sales decreased from 500 units to 400 units. What is the percentage decrease?
- Calculate the Decrease: 500 - 400 = 100
- Identify the "Part" and "Whole": The decrease (100) is the "Part," and the original sales (500) is the "Whole."
- Apply the Formula: (100 / 500) x 100
- Calculate: 0.2 x 100 = 20%
Answer: Sales decreased by 20%.
