Sale maths can be tricky: 30% off and then an extra 10% off is a 37% discount, not 40%, because the second discount applies to the already-reduced price. Coupons, cashback and tax change the final figure again.
Enter the price and the discount, plus any extra discount, flat coupon and tax. The calculator gives the sale price, the saving, the real overall discount, the price with tax, the step-by-step working and a table of common discounts.
