How to Calculate Percentage of Money

The basic formula for calculating a percentage of money is:

Percentage Formula

Percentage = (Part / Whole) × 100

Where:

Part is the amount you want to find the percentage of
Whole is the total amount

For example, to find what percentage $25 is of $100:

Example Calculation

(25 / 100) × 100 = 25%

This means $25 is 25% of $100.

Note

When calculating percentages of money, always ensure you're using the correct values for "Part" and "Whole" to get an accurate result.

Common Percentage Calculations

Here are some common scenarios where percentage calculations are used with money:

Scenario	Calculation Example
Calculating a 10% discount on $50	(10 / 100) × 50 = $5 discount
Determining a 15% tip on a $75 bill	(15 / 100) × 75 = $11.25 tip
Finding what percentage $30 is of $120	(30 / 120) × 100 = 25%
Calculating a 5% sales tax on $200	(5 / 100) × 200 = $10 tax

These examples demonstrate how percentage calculations apply to real-world financial situations.

Percentage Calculation Examples

Let's look at several practical examples of calculating percentages of money:

Example 1: Discount Calculation

You want to buy an item priced at $80 with a 25% discount. How much will you pay?

Calculation: (25 / 100) × 80 = $20 discount

Final price: $80 - $20 = $60

Example 2: Tip Calculation

You had a meal that cost $125 and want to leave a 20% tip. How much should you tip?

Calculation: (20 / 100) × 125 = $25 tip

Example 3: Investment Return

You invested $500 and it grew to $650. What was the percentage return?

Calculation: ((650 - 500) / 500) × 100 = 30% return

These examples show how percentage calculations help in various financial contexts.
