Percentage = (Part ÷ Whole) × 100
To find a specific percentage of a number:
Value = (Percentage ÷ 100) × Total Amount
This formula works for any percentage calculation. For example, to find 20% of 500:
(20 ÷ 100) × 500 = 100

Common Mistakes
When calculating percentages, these common errors can occur:
- Forgetting to convert the percentage to a decimal before multiplying
- Using the wrong total amount in the calculation
- Rounding too early in the calculation process
- Confusing percentage points with percentages (e.g., 10% vs. 1 percentage point)
Double-check your calculations to avoid these mistakes.
FAQ
- How do I calculate percentages without a calculator?
- You can use the decimal conversion method or break the percentage into simpler parts, as shown in the worked example.

- You might need to calculate percentages for budgeting, shopping discounts, tips, loan interest, investment returns, and many other practical applications.
- What if I need to calculate a percentage increase or decrease?
- Use the formula: Percentage Change = [(New Value - Original Value) ÷ Original Value] × 100. For example, a 10% increase on $100 would be $110.
