Common Percentage Calculations
There are different ways to calculate percentages. Understanding these methods helps you choose the right calculation for your needs.
How to Calculate a Percentage of a Number
To find a percentage of a number, divide the percentage by 100 and multiply the result by the original number.
Formula:
Percentage of a number = (Percentage ÷ 100) × Number
Example:
Suppose you want to find 25% of 400.
25 ÷ 100 = 0.25
0.25 × 400 = 100
Therefore, 25% of 400 is 100.
You can use this method to calculate discounts, taxes, marks, commissions, and other percentage-based values.
How to Find What Percentage One Number Is of Another
Sometimes, you know two numbers but want to determine what percentage the first number represents of the second.
Formula:
Percentage = (Part ÷ Total) × 100
Example:
A student receives 72 marks out of 90.
(72 ÷ 90) × 100 = 80%
The student's score is 80%.
This calculation is useful for exam results, survey responses, business performance, and progress tracking.
How to Calculate Percentage Increase
A percentage increase shows how much a value has grown compared with its original amount.
Formula:
Percentage Increase = ((New Value − Original Value) ÷ Original Value) × 100
Example:
The price of a product increases from $200 to $250.
First, calculate the difference:
$250 − $200 = $50
Next, divide the difference by the original price:
50 ÷ 200 = 0.25
Multiply by 100:
0.25 × 100 = 25%
The price has increased by 25%.
How to Calculate Percentage Decrease
A percentage decrease shows how much a value has fallen compared with its original amount.
Formula:
Percentage Decrease = ((Original Value − New Value) ÷ Original Value) × 100
Example:
A jacket originally costs $100 but is now available for $75.
$100 − $75 = $25
($25 ÷ $100) × 100 = 25%
The jacket's price has decreased by 25%.
This calculation is helpful when comparing sale prices, expenses, product prices, or monthly costs.
Practical Uses of a Percentage Calculator
A percentage calculator can help with many everyday tasks. Here are some common examples.
Calculate Shopping Discounts
Online stores and retail shops frequently offer percentage-based discounts. A calculator helps you determine the amount you save and the final price.
For example, if a product costs $80 and has a 15% discount, the discount amount is $12. The final price before any additional taxes or fees is $68.
Calculate Exam Marks
Students can calculate their examination percentages by dividing the marks they earned by the total possible marks and multiplying by 100.
For instance, if you score 450 out of 600 marks, your percentage is 75%.
Calculate Business Profit
Business owners can use percentage calculations to understand changes in revenue, expenses, and sales. They can also calculate profit margins when they know the profit and revenue figures.
For example, if a business earns $2,000 in revenue and makes $400 in profit, its profit margin is 20%.
Profit margin is different from markup, so it is important to use the correct formula for your business calculation.
Calculate Taxes and Tips
Percentage calculations can help estimate sales tax, service charges, and tips. For example, a 10% tip on a $50 bill is $5.
Actual tax rates depend on the location and applicable rules, so always check the relevant rate before making a payment.
Track Price Changes
You can compare old and new prices to find the percentage increase or decrease. This is useful when checking subscription costs, comparing product prices, or reviewing changes in household expenses.

Percentage Calculator Examples
The following table shows examples of common percentage calculations.
Calculation | Example | Answer |
|---|---|---|
10% of 200 | 200 × 0.10 | 20 |
25% of 400 | 400 × 0.25 | 100 |
50 out of 200 | (50 ÷ 200) × 100 | 25% |
Increase from 100 to 150 | ((150 − 100) ÷ 100) × 100 | 50% |
Decrease from 80 to 60 | ((80 − 60) ÷ 80) × 100 | 25% |
20% discount on $150 | $150 × 0.20 | $30 off |
These examples demonstrate how percentage formulas can solve different types of problems. Remember that the original value matters when calculating percentage increases and decreases.
Percentage vs. Percentage Points
Percentage and percentage points are related but have different meanings.
A percentage describes a proportion relative to a whole. A percentage point describes the arithmetic difference between two percentages.
For example, if a conversion rate increases from 4% to 6%, it has increased by 2 percentage points. The relative percentage increase is 50%, because the increase of 2 is divided by the original rate of 4 and multiplied by 100.
Understanding this difference is useful when reviewing statistics, interest rates, marketing results, and business reports.
