How this discount calculator works
Percentage saving = original price x discount rate. Final price = original price - percentage saving - extra flat off, limited to zero.
Worked example
If a product priced at ?4,999 has 30% off, the saving is about ?1,500 and final price is about ?3,499 before taxes, delivery fees or payment offers.
Assumptions
- The percentage discount applies to the original price.
- Extra flat off is applied after the percentage saving.
- The final price cannot go below zero.
- Taxes, shipping and card offers are not included unless entered in the price.
Limitations
- Retailers may apply coupons, wallet offers and taxes in a different order.
- The calculator does not verify actual product prices or offers.
- Use merchant checkout totals before purchase.
