How this is worked out
The saving is the original price × the discount percentage. The final price is the original price minus that saving.
Worked example
- Original price £120.00
- Discount 25%
120 × 0.25 = 30, and 120 − 30 = 90
£90.00, saving £30.00
Assumptions and limits
- Applies one discount to one price. Stacked offers such as an extra 10 per cent off a sale price must be run twice.
- The result follows whichever price you enter, so it includes VAT only if your original price does.
