How to work it out

  1. Work out the discount: 5% of 30 = 0.05 × 30 = 1.5
  2. Take it off the price: 30 − 1.5 = 28.5
  3. Check: Add the saving back: 28.5 + 1.5 = 30.

Another method. In one step: you pay 95% of the price, so 0.95 × 30 = 28.5. Both methods always give the same answer.

In a spreadsheet: =30*(1-5%). 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 5% off, you pay 95% of the price: 28.5 instead of 30, a saving of 1.5.

Shopping: an item marked $30 with 5% off costs $28.5 at the till, before any sales tax.

Stacked discounts

5% off followed by another 5% off is 9.75% off in total, not 10%: the second discount applies to the lower price.
