Discount Calculator FAQs

How do I calculate a percentage discount?

Multiply the original price by the discount percentage (as a decimal), then subtract that amount from the original price. For example: $100 × 20% = $20 discount, so sale price = $100 - $20 = $80.

What's the difference between percentage and fixed amount discounts?

Percentage discounts scale with the original price (e.g., 20% off), while fixed amount discounts subtract a specific dollar amount (e.g., $20 off). Percentage discounts are better for expensive items, fixed amounts for cheaper items.

How do stacked discounts work?

Stacked discounts are applied sequentially, not added together. A 20% discount followed by a 10% discount results in a 28% total discount (not 30%), because the second discount applies to the already reduced price.

Should tax be calculated on the original or sale price?

This depends on local regulations. Most jurisdictions calculate sales tax on the final sale price after discounts, but some may tax the original price. Check your local tax laws for specific requirements.

What's a good discount percentage?

A "good" discount depends on the product and context. For retail, 20-30% is typically substantial. For clearance items, 50-70% is common. Always compare to historical prices and competitor pricing.
