Promo Code Discount Formula

This calculator uses a simple formula to determine the final price.

Discount Amount = Original Price x (Discount Percentage / 100)

Sales Tax Amount = (Original Price – Discount Amount) x (Sales Tax Percentage / 100)

Final Price = Original Price – Discount Amount + Sales Tax Amount

Example: Let’s say you have a promo code for 20% off a $50 item, and the sales tax in your area is 6%.

  • Discount Amount = $50 x (20 / 100) = $10
  • Sales Tax Amount = ($50 – $10) x (6/100) = $2.40
  • Final Price = $50 – $10 + $2.40 = $42.40
