Compare online deal types to see your real total before you check out
💡 Why This Matters Cyber Monday deals come in the same tricky shapes as in-store sales — BOGO, 2-for-1, 3-for-2 — but you've got no salesperson to ask and a cart that's easy to overfill. Pick the deal type and see exactly what you'll pay and save before you hit checkout.
The term "Cyber Monday" wasn't coined by accident — the National Retail Federation introduced it in a 2005 press release specifically to nudge people toward shopping online after Black Friday's in-store rush.

Each deal type uses its own math. Percent off: final = price − (price × %÷100). BOGO % off: pay full price for one item, a reduced price for the second. 2-for-1: pay for one item per pair. 3-for-2: pay for two items per set of three. Pick the tab matching your deal and this calculator applies the right formula automatically — no more mental math while your cart timer counts down.
The bigger-sounding deal isn't always the better one. A 40% off second item (BOGO) saves 20% total across two equal-priced items — noticeably less than a straight 30% off everything, even though "40% off" reads as the bigger number in a banner ad.
This calculator handles the deal math on the item price itself — it doesn't factor in shipping, handling fees, or sales tax, all of which vary by retailer and can meaningfully change whether an online deal is actually worth it. It also assumes equally-priced items within a deal, the standard case for these promotions.
Run every deal you're comparing through the matching tab before adding to cart. Cyber Monday tends to skew toward electronics and tech, so it's especially worth double-checking bundle deals and "buy 2, get 1 free" accessory offers where the math is easy to misjudge quickly.
Example: An online store offers "buy a set of headphones, get the second pair 40% off" at $50 each. You pay full price ($50) for the first, and $50 × 0.60 = $30 for the second. Total = $80 for two pairs, saving $20 off the $100 combined price — a 20% total discount, even though the banner reads "40% off."
Four common Cyber Monday deal formats: straight percent off, buy-one-get-one at a percent off, 2-for-1, and 3-for-2. For stacked online discounts (a sale price plus a coupon code), use the dedicated Double Discount or Triple Discount calculators instead.
Not universally — Cyber Monday tends to focus more on electronics and tech, while Black Friday spans more categories overall. The best move is running the actual numbers for whichever specific deal you're looking at, on whichever day it's offered.
No — this tool calculates the deal math on the item price itself. Add any shipping or handling fees to the final result separately, since those vary by retailer and aren't part of the discount calculation.
