Frequently Asked Questions
How do stacked discounts work (e.g., 20% off + extra 10% coupon)?
Sequential discounts apply the second discount to the already reduced price, not added together (20% then 10% equals 28% total discount, not 30%).
Does this calculator include sales tax?
Yes, you can toggle your local sales tax or VAT rate to see the exact out-of-pocket register cost.
