How to work it out

  1. Work out the discount: 70% of 20 = 0.7 × 20 = 14
  2. Take it off the price: 20 − 14 = 6
  3. Check: Add the saving back: 6 + 14 = 20.

Another method. In one step: you pay 30% of the price, so 0.3 × 20 = 6. Both methods always give the same answer.

In a spreadsheet: =20*(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: 6 instead of 20, a saving of 14.

Shopping: an item marked $20 with 70% off costs $6 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.
