How to work it out

  1. Work out the discount: 70% of 10 = 0.7 × 10 = 7
  2. Take it off the price: 10 − 7 = 3
  3. Check: Add the saving back: 3 + 7 = 10.

Another method. In one step: you pay 30% of the price, so 0.3 × 10 = 3. Both methods always give the same answer.

In a spreadsheet: =10*(1-70%). Taking the percentage of the price gives the saving, not the price you pay. Subtract it, or multiply by the share that is left.

What the result means

After 70% off, you pay 30% of the price: 3 instead of 10, a saving of 7.

Shopping: an item marked $10 with 70% off costs $3 at the till, before any sales tax.

Stacked discounts

70% off followed by another 70% off is 91% off in total, not 100%: the second discount applies to the lower price.
