Formula of Final Sale Price Calculator
1. Final Sale Price with a Discount
Final Sale Price = Original Price − (Original Price × Discount Percentage)
Example: If the price is $100 and the discount is 20%:
$100 − ($100 × 0.20) = $80
2. Final Sale Price with Tax
Final Sale Price = (Original Price − Discount) + [(Original Price − Discount) × Tax Rate]
Or combined:
Final Sale Price = (Original Price × (1 − Discount Percentage)) × (1 + Tax Rate)
Example: For a $100 item with a 20% discount and 10% tax:
($100 × 0.80) × 1.10 = $88
3. Final Sale Price with a Fixed Discount
Final Sale Price = Original Price − Discount Amount + [Tax Rate × (Original Price − Discount Amount)]
Example: For a $200 product with $30 off and 5% tax:
$200 − $30 + [0.05 × $170] = $178.50

Example of Final Sale Price Calculator
Suppose you plan to buy a backpack that costs $150. There’s a 25% discount and your local sales tax is 7%.
Price after discount:
$150 − ($150 × 0.25) = $112.50
Add tax:
$112.50 × 1.07 = $120.38
So, the final sale price you pay is $120.38.
Most Common FAQs
Always apply the discount first, then add tax to the discounted amount. This reflects how stores usually calculate the final price.
A fixed discount takes off a set dollar amount, like $20 off. A percentage discount reduces the price by a percentage, like 15% off.
Use the calculator step by step: apply the first discount, get the new price, then apply the next discount if needed. Finish by adding tax last.
