How to Use Percentages in Everyday Life

Percentages aren’t just math class material — they’re a daily part of life. Whether you’re shopping for a deal, calculating a tip, or reviewing test scores, understanding percentages can save you money and help you make smarter decisions.

1. Shopping and Discounts

When a store advertises 20% off, it means you save 20 out of every 100 in currency. For example, if something costs €50 and is 20% off, you calculate 20% of €50 (€10) and subtract it. You pay €40.

2. Tips and Bills

Percentages are handy when tipping at restaurants. A common tip is 10–15%. If your bill is €30 and you want to tip 15%, that’s €4.50.

3. School and Exams

If you got 18 out of 20 questions right, you scored 90%. Just divide 18 by 20 and multiply by 100. Percentages make it easy to compare scores and set goals.

4. Budgeting and Finance

Let’s say you want to save 25% of your monthly salary. If you earn €2,000, that’s €500 to set aside. Knowing percentages helps with savings goals, investments, and tracking expenses.

5. Bonus: Using Online Tools
