How discount calculation works
Final Price = Original Price × (1 − Discount% ÷ 100)
Savings = Original Price × Discount% ÷ 100
Discount % = (Original − Sale) ÷ Original × 100
Discounts are common in retail sales, Black Friday, seasonal promotions, and wholesale pricing. Knowing the actual savings before a purchase helps make better buying decisions.
Frequently Asked Questions
How do I calculate 20% off a price?
Multiply the original price by 0.80 (which is 1 − 0.20). Example: €100 × 0.80 = €80. Or enter 100 and 20% in the calculator above.
How do I find the original price from a discounted price?
Divide the discounted price by (1 − discount% ÷ 100). Example: sale price €80 with a 20% discount: €80 ÷ 0.80 = €100 original price.
What is a good discount percentage?
It depends on the context. Retail seasonal sales are typically 10–30%. Major clearance events like Black Friday can offer 30–70%. Any discount above 50% is generally considered substantial.
