Worked Examples

Let's look at some practical examples to illustrate how to use the money calculator percentage.

Example 1: Calculating a 15% Discount

You're shopping and find a shirt that's originally priced at $50. The store is offering a 15% discount. How much will you save?

Discount = ($50 × 15) ÷ 100 = $7.50

You'll save $7.50 on the shirt.

Example 2: Calculating a 18% Tip

You've enjoyed a meal at a restaurant with a total bill of $85. You want to leave an 18% tip. How much should you tip?

Tip = ($85 × 18) ÷ 100 = $15.30

You should leave a $15.30 tip.

Example 3: Calculating a 10% Increase

Your salary has increased by 10%. If your previous salary was $4,000, what is your new salary?

Increase = ($4,000 × 10) ÷ 100 = $400

New Salary = $4,000 + $400 = $4,400

Your new salary is $4,400.
