Sale price per item
150 × (1 − 25 % ÷ 100) = 112.5 - 2
Cashback per item
112.5 × 5 % ÷ 100 = 5.63 - 3
Net cost per item
112.5 − 5.63 = 106.88 - 4
Total cost (all items + shipping)
106.88 × 1 + 0 = 106.88
How does this calculator work?
Cyber Monday final cost = Original × (1 − disc%) × (1 − cashback%) + shipping. A 25% discount plus 5% cashback on a $150 item gives an effective cost of ~$107. Enter price, discount, cashback and shipping to find your true out-of-pocket total and percentage saved.
Formula
How this is calculated
A Cyber Monday discount reduces the listed price by the advertised percentage: 25% off $150 brings the sale price to $112.50. On top of that, many shoppers use credit cards or affiliate portals that return a further percentage of the sale price as cashback or reward points — a 5% cashback on $112.50 yields $5.63 back, making the effective cost $106.87.
Shipping is added after the discount, because free-shipping thresholds and promotional rates differ by retailer. The calculator adds any flat shipping fee on top of the per-item totals, giving you the true out-of-pocket cost for the order.
The "savings vs original" figure is (Original − Final) / Original × 100. Note that cashback may be credited to your account days or weeks after the purchase rather than reducing the checkout total immediately, so the real-time payment and the effective cost differ — both are shown in the breakdown.
Frequently asked questions
Credit-card and portal cashback is applied to the amount actually charged, which is the discounted sale price. This calculator applies cashback after the discount, which is the standard industry method.
Enter each deal separately — same original price, same discount, but different cashback percentages — and compare the "total cost" results. A 3% cashback on a 30%-off item can beat a 5% cashback on a 20%-off item depending on price.
Shipping cost is a flat amount, so it represents a larger percentage of a small purchase. A $10 delivery fee on a $40 item is 25% of the order; on a $400 item it is only 2.5%. Use the shipping field to see the true impact on each order.
