A discount has two useful answers
The money saved tells you the value of the offer. The final price tells you what remains to pay before any taxes, shipping or fees.
Step 1: Calculate the amount saved
Multiply the original price by the discount rate and divide by 100.
Money saved = Original price × Discount rate ÷ 100
Step 2: Calculate the final price
Subtract the amount saved from the original price.
Final price = Original price − Money saved
You can also calculate it directly with Original price × (1 − Discount rate ÷ 100).
Example: 30% off $85
- Money saved: $85 × 30 ÷ 100 = $25.50.
- Final price: $85 − $25.50 = $59.50.
You save $25.50 and pay $59.50 before tax or fees.
Example: 15% off $60
Ten percent of $60 is $6 and five percent is $3, so 15% is $9. Subtracting $9 from $60 gives a final price of $51.
Stacked discounts are multiplied, not added
A 20% discount followed by a 10% discount is not 30% off. A $100 price first becomes $80. The second discount removes 10% of $80, leaving $72. The combined saving is $28, or 28%.
$100 × 0.80 × 0.90 = $72
Check tax, fees and exclusions
A discount calculation usually covers the listed item price only. Tax rules, shipping, service charges, minimum spending and excluded products can change the checkout total. Use the final displayed price when making a purchase decision.
