Worth knowing
What percentages actually do.
Enough to stop a price tag feeling like a trap.
A percentage of something
“25% of £89” means twenty-five pounds in every hundred. Divide the amount by 100, then multiply by 25. That's £22.25 — and it's why the discount matters more on bigger numbers.
Percentage increase
To find how much something grew, divide the change by the original figure, then multiply by 100. Going from £80 to £92 is a rise of £12; £12 ÷ £80 = 0.15, so that's a 15% increase. The original is the number you divide by — not the new one.
Why 50% off then 50% off isn't free
Two discounts don't add up — they multiply. Take 50% off, then 50% off again, and you've paid 50% of 50%, which is 25% of the original. Still a great deal, just not quite the 100% it sounds like.
