The answer is 5. Below: three ways to calculate it, a mental shortcut, and the real-world contexts where this percentage shows up.
5% of 100 is 5.
A 5% commission is common in real estate splits and small affiliate programs.
Divide the percent by 100 to convert it: 5 ÷ 100 = 0.05.
Multiply: 100 × 0.05 = 5.
5% means 5/100. So 5% of 100 is (5 × 100) ÷ 100.
Compute: 5 × 100 = 500, then divide: 500 ÷ 100 = 5.
For 5%, find 10% (decimal one place left) and halve it. 10% of 100 is 10; half of that is 5.
A commission is a percentage of a transaction paid to a salesperson or affiliate. The base is usually the gross sale amount.
A 5% commission on a $100 sale pays the seller $5.

| Calculation | Answer |
|---|---|
| 5% of 2 | 0.1 |
| 5% of 3 | 0.15 |
| 5% of 5 | 0.25 |
| 5% of 10 | 0.5 |
| 5% of 15 | 0.75 |
For any percentage of any number, use our percentage of a number calculator.
Multiply 100 by 0.05 (the decimal form of 5%). Or equivalently, multiply by 5/100. The result is 5.
Divide 5 by 100 and multiply by 100. That is exactly 5% — confirming the original calculation.
