Formula & Calculation Method
Discount Calculation Formula:
Discount Amount = Original Price × (Discount % / 100)
Final Price = Original Price - Discount Amount
OR
Final Price = Original Price × (1 - Discount % / 100)
Example: If an item costs $100 with a 20% discount:
Discount Amount = $100 × (20 / 100) = $100 × 0.20 = $20
Final Price = $100 - $20 = $80

Frequently Asked Questions
How do I calculate multiple discounts?
For multiple discounts, apply them sequentially. Calculate the first discount on the original price, then apply the second discount to that result. Note: Applying 20% then 10% is different from a single 30% discount.
Does this include sales tax?
No, this calculator only calculates the discount amount. Sales tax (if applicable) would be calculated on the final discounted price.
Can I use this for bulk discounts?
Yes! Enter the total price before discount and the percentage off. This works for both individual items and bulk purchases.
What if I know the final price but not the discount percentage?
To find the discount percentage, use the formula: Discount % = [(Original Price - Final Price) / Original Price] × 100.
