Accuracy Standards & Best Practices
- Compounding Discounts: If a store offers '20% off plus an extra 10% off', that does NOT equal 30% off. The 10% applies to the already discounted price, resulting in a net 28% discount.
- Factor In Taxes: Remember that sales tax or GST is generally calculated on the discounted post-sale price, saving you tax money as well.
Frequently Asked Technical Questions
How do I calculate a discount manually?
Multiply the original price by the discount rate divided by 100 to get savings: Savings = Price × (Discount ÷ 100). Subtract savings from original price to get final price.
How do I reverse calculate the original price?
If you know the sale price and discount percentage: Original Price = Sale Price ÷ (1 - Discount / 100).
What is the difference between margin and discount?
A discount is a reduction applied to the retail selling price, whereas profit margin is the percentage of the selling price that is profit over cost.
