Estimate what an item costs after a sale percentage and an optional second discount, while showing how sequential discounts combine.
Final price$90.00

How this tool works
Final price = original × (1−d₁) × (1−d₂). Effective discount = 1 − final/original.
Example
A $120 item discounted 25% costs $90; an additional 10% discount makes it $81, an effective 32.5% reduction rather than 35%.
Common questions
Do two discounts simply add together?
No. Sequential discounts multiply against the reduced price, so 25% then 10% equals a 32.5% effective discount.
Does the calculator include tax?
No. Use the Sales Tax Calculator on the discounted price if tax is applied afterward.
