How to work it out

  1. Work out the discount: 30% of 20 = 0.3 × 20 = 6
  2. Take it off the price: 20 − 6 = 14
  3. Check: Add the saving back: 14 + 6 = 20.

Another method. In one step: you pay 70% of the price, so 0.7 × 20 = 14. Both methods always give the same answer.

In a spreadsheet: =20*(1-30%). 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 30% off, you pay 70% of the price: 14 instead of 20, a saving of 6.

Shopping: an item marked $20 with 30% off costs $14 at the till, before any sales tax.

Stacked discounts

30% off followed by another 30% off is 51% off in total, not 60%: the second discount applies to the lower price.
