BOGO & multi-buy calculator
“Buy 2, get 1 50% off” sounds generous, but what is it per item? Enter the item price and the offer structure to see the total you pay, the effective price per item and the real percentage saved.
Effective discount16.7% off
Total for 3 items$75.00
Price per item$25.00
Without the offer$90.00
You save$15.00
Only worth it if you need all 3 items. Buying just 2 saves nothing.
How it works
- Total = (items you buy × price) + (free/discounted items × price × (1 − discount ÷ 100)).
- Effective discount = savings ÷ (all items × full price) × 100.
- It assumes every item costs the same. Stores usually discount the cheapest item when prices differ.

Questions
Is BOGO the same as 50% off?
Only if you need both items. Buy one get one free equals 50% off each item when you buy two, but it saves nothing on a single item.
Which item is free when prices differ?
Most retailers make the lowest-priced item free or discounted. Check the offer terms.
