Discount & Tax Equations
Step-by-Step Worked Retail Example
Example Scenario:
Suppose a retail item originally priced at $120.00 is on sale for 25% off, with a local sales tax of 8%:
- Discount Amount: $120.00 × 0.25 = $30.00
- Discounted Net Price: $120.00 − $30.00 = $90.00
- Sales Tax Amount (8%): $90.00 × 0.08 = $7.20
- Final Total Paid at Checkout: $90.00 + $7.20 = $97.20
- Total Net Savings: $120.00 − $97.20 = $22.80
Frequently Asked Questions
Q: How is a discount percentage calculated?
Discount amount is calculated by multiplying the original price by the discount percentage: Discount Amount = Original Price × (Discount % ÷ 100). The discounted price equals Original Price minus Discount Amount.
Q: Is sales tax / VAT applied before or after a discount?
In standard retail accounting, sales tax and Value Added Tax (VAT/GST) are applied AFTER the discount is subtracted from the original price, ensuring you only pay tax on the actual net purchase price.
Q: How do you extract the pre-tax price from a VAT-inclusive total?
To find the pre-tax price from a total that includes VAT, divide the gross total by (1 + VAT Rate): Pre-Tax Price = Gross Total ÷ (1 + Tax Rate).
