What is 40% of 500?
The answer is 200.
Result Explanation
40% of 500 = 200. If you are subtracting this as a discount, the discounted total is 500 − 200 = 300. If you are allocating, 200 is the allocated amount and 300 is the remainder.
Quick check: compare 500 × 0.4 with (40 ÷ 100) × 500; both should equal 200.
How It Works
Step 1: Express 40% as a decimal: 40 ÷ 100 = 0.4.
Step 2: Multiply by 500: 0.4 × 500 = 200.
Full formula: (40 ÷ 100) × 500 = 200
Fraction shortcut: 40% = 2/5; (2/5) × 500 = 200.
Ten-percent ladder: 10% of 500 is 50; 40% = 4 × 50 = 200.
Split base: 40% of 400 + 40% of 100 = 160 + 40 = 200.
Five hundreds: 40% of 100 = 40; 5 × 40 = 200.
Double two hundred fifty: 40% of 250 = 100; for 500, 2 × 100 = 200.
Strategy & Insight
Compare with four hundred: forty percent of four hundred is 160, and the extra one hundred units in the base add 40 to the slice at the same rate—four tenths per unit. That “plus one hundred, plus forty” pattern scales whenever you step the base by centuries.
At a fixed forty percent rate, each one-unit increase in the base adds 0.4 to the slice. From four hundred ninety-nine to five hundred one, the amount moves by eight tenths around 200.
Common Mistakes
- Answering 160 by using forty percent of four hundred while the base is five hundred.
- Multiplying 500 by 40 instead of 0.4.
- Quoting 300 when the prompt asked only for the forty percent share.
- Confusing forty percent of five hundred with adding forty percent to five hundred.
Pro Tip
Think in five hundreds: forty percent of one hundred is always 40 at this rate, so five centuries yield 200 without touching point four.
Examples
Example 1: Five hundred pound budget line
A £500.00 line assigns forty percent to tooling: £200.00 on tooling and £300.00 elsewhere in the simple split before VAT.
Example 2: Points pool
A sprint caps at 500 story points; forty percent for debt is 200 points, leaving 300 points for features in the naive model.
Example 3: Survey
Out of 500 responses, forty percent choosing “yes” is 200 people; the other 300 spread across other answers before weighting.

Why is 40% of 500 not 160?
