What is the difference between percentage and fixed discount?

A percentage discount reduces the price by a proportion — for example, 20% off means you pay 80% of the original. A fixed discount deducts a specific amount regardless of the price — for example, $10 off means you always save $10. Percentage discounts benefit more on expensive items, while fixed discounts may represent a bigger saving on cheaper items.

How is tax calculated with a discount?

Tax is typically applied after the discount. First, the discount reduces the original price to the sale price. Then, the tax percentage is applied on top of the sale price. For example, if a $100 item has a 20% discount and 10% tax: Sale price = $80, Tax = $8, Final price = $88. This calculator follows this standard method.

How can I find the original price from a discounted price?

To find the original price when you only know the sale price and discount percentage, divide the sale price by (1 - discount% / 100). For example, if you paid $80 after a 20% discount: Original price = 80 / (1 - 0.20) = 80 / 0.80 = $100. This is useful when you see a discounted price tag and want to know what the item originally cost.

What is a good discount percentage?

A "good" discount depends on the product and retailer. For clothing and fashion, 20–50% off is common during sales. For electronics, discounts of 10–30% are typical. Seasonal clearance sales often offer 50–70% off. Discounts above 70% are rare and may indicate end-of-life products or quality issues. Always compare the sale price against competitors to make sure you're getting a true deal.

Frequently Asked Questions

To calculate a percentage discount, multiply the original price by the discount percentage, then divide by 100. For example, a 20% discount on a $50 item: 50 × 20 / 100 = $10 savings, so the sale price is $40. The formula is: Sale Price = Original Price × (1 - Discount% / 100).
