Practical scenario
Supplier quotation
Calculate the reduction from list price before comparing net quotations from different suppliers.
Practical scenario
Successive discounts
Apply the first discount, then use the reduced price as the base for the second; two discounts are not normally added together directly.
Common mistakes to avoid
- • Adding successive discount percentages together
- • Calculating discount from the final rather than original price
- • Ignoring tax, delivery or mandatory fees
- • Comparing percentage savings without comparing the actual final price
Professional planning tips
- • Verify the original reference price before judging a promotion.
- • For successive discounts, calculate each stage separately.
- • Compare the final payable amount across sellers.
- • Keep discount and tax calculations separate for clearer reconciliation.
Frequently asked questions
How is the discount amount calculated?
Multiply the original price by the discount percentage divided by 100.
How is the final price calculated?
Subtract the discount amount from the original price.
Are two 20% discounts equal to 40%?
No. The second discount is normally applied to the already-reduced price, producing a combined reduction of 36%.
Does the calculator include tax?
No unless the entered prices already include it. Calculate tax according to the applicable pricing and invoice method.
Can I calculate the original price from a sale price?
That requires a reverse-discount calculation using the sale price and known discount percentage.
Why can the checkout amount differ?
Delivery, tax, minimum-spend rules, excluded products or rounding can change the final payable amount.
