Common Use Cases
Tips & Best Practices
Black Friday "70% off" often means 70% off a marked-up price — use this tool to verify real savings
Stack discounts properly: $100 with 20% off + 10% off = $72, not $70
Retailers use this to price products at a target margin after expected discounts
Frequently Asked Questions
How do I stack multiple discounts?
Apply discounts sequentially. A 20% off then 10% off is not 30% — it's 28%. Use the tool twice: first apply 20%, then apply 10% to the result.
How do I find the discount percentage from two prices?
Enter the original and sale price. The calculator shows the equivalent discount percentage.
