How to calculate a percentage of an amount

A percentage is a way to express a part of a whole as a fraction of 100. The word "per cent" literally means "per hundred". So 15% means 15 out of every 100, or 15÷100 = 0.15. To find a percentage of a rand amount, you multiply the amount by that decimal (or by the percentage and divide by 100 — same answer).

The formula

Result = Amount × Percentage ÷ 100
Example: 15% of R1,000 = 1000 × 15 ÷ 100 = R150

Mental-maths shortcuts

  • 10% of any amount: move the decimal one place to the left. R450 → R45.
  • 5% of any amount: calculate 10%, then halve it. R450 → R45 → R22.50.
  • 15% (typical tip): 10% + half of 10%. R450 → R45 + R22.50 = R67.50.
  • 20%: 10% × 2. R450 → R45 → R90.
  • 25%: divide by 4. R400 → R100.
  • 50%: divide by 2. R450 → R225.
  • 75%: 50% + 25%. R400 → R200 + R100 = R300.

Worked examples in rands

Example 1 — A 15% restaurant tip

Your bill at a Cape Town restaurant comes to R720. You want to tip 15%.

720 × 15 ÷ 100 = R108 tip · Total: R828

Example 2 — A 30% sale discount

A jacket is marked R1,299 with 30% off the rail.
