Which calculator do I need?
- What is X% of Y: a tip, a commission, or 3% withholding tax on a payment.
- X is what percent of Y: a test score (45 out of 60 = 75%), or a share of a total.
- Percentage change: how much a price, salary or sales figure went up or down.
- X is P% of what: work back to the full amount, such as the total when a 20% deposit was ฿300.
Good to know
- Two discounts don't add up: 50% off and then another 10% off is 55% off in total, not 60%, because the second discount comes off the already-reduced price.
- Margin is profit as a share of the selling price; markup is profit as a share of the cost. Buying at 80 and selling at 100 is a 20% margin but a 25% markup.
- Going up by a percentage and back down by the same percentage doesn't return to the start: 100 + 10% = 110, and 110 − 10% = 99.
