❓ Does Sales Tax Apply Before or After Discount?

By default, sales tax applies to the reduced post-discount price. For example, a $100 item with a 20% discount ($80) and 8% tax adds $6.40 tax, making the total $86.40.

Discount + Tax Formula: Final Total = Original Price × (1 − Discount / 100) × (1 + Tax Rate / 100)

❓ Frequently Asked Questions (FAQ)

How do I calculate discount and sales tax? ▼
Calculate the discounted price first, then multiply the discounted price by (1 + Sales Tax Rate / 100) to find the final checkout total.

By default, this calculator applies sales tax to the discounted price. Actual tax treatment can vary by jurisdiction, product, and transaction.

For a $100 item: 20% off reduces price to $80. 8% sales tax on $80 adds $6.40 tax, bringing final total to $86.40.
How do I calculate final price after discount and tax? ▼
Use the formula: Final Total = Original Price × (1 − Discount / 100) × (1 + Tax Rate / 100).
