What Is a Buy One Get One Offer?
A Buy One Get One offer, commonly called BOGO, is a promotional pricing strategy where a customer receives an additional item after purchasing one or more qualifying items.
The most familiar version is Buy One Get One Free, where a customer pays for one item and receives another item at no additional product cost.
How to Use the Buy One Get One Calculator
- Enter the regular price of one item.
- Enter the number of items you pay for.
- Enter the number of free items received.
- Select Calculate Deal.
- Review the total items, amount paid, savings, and effective price per item.
BOGO Calculator Formula
The total number of items received is calculated by adding paid items and free items.
The amount paid is the regular item price multiplied by the number of paid items.
The value of the free items represents the customer's savings compared with buying every item at the regular price.
The effective price per item shows the amount actually paid divided across every item received.
Buy One Get One Free Example
Suppose one item normally costs $20 and a store offers Buy One Get One Free.
Paid Items: 1
Free Items: 1
Total Items: 2
Amount Paid: $20
Savings: $20
Effective Price Per Item: $10
Although the customer pays $20, they receive two $20 items. The effective price works out to $10 per item.
What Is the Effective Discount on BOGO Free?
A standard Buy One Get One Free offer gives the customer two items for the price of one. When both items have the same regular price, the effective discount is 50% across the two items.
Amount Paid: $20
Savings: $20
Effective Discount: 50%
Buy Two Get One Free
BOGO-style promotions can also require customers to purchase multiple items before receiving a free item. For example, a Buy Two Get One Free offer provides three items while the customer pays for two.
Free Items: 1
Total Items: 3
Effective Discount: 33.33%
The effective discount is lower than Buy One Get One Free because the customer pays for two of the three items.
Why Calculate the Effective Price?
The advertised BOGO offer does not always tell you the effective price of each item. Dividing the amount paid by the total number of items gives a clearer view of the actual average cost per item.
This can be useful when comparing promotions, retailers, bundles, and regular prices.
Things to Check Before Accepting a BOGO Deal
- Check the regular price of the item.
- Confirm whether the free item must be identical.
- Check whether the promotion has quantity limits.
- Review applicable taxes and fees.
- Check whether a membership or coupon is required.
- Make sure you actually need the additional items.
- Compare the effective price with competing offers.
BOGO vs. 50% Off
When two identical items have the same price, Buy One Get One Free can have an effective discount equivalent to 50% off the combined purchase.
However, the two promotions can work differently when products have different prices or when the promotion restricts which item becomes free.
