Bundle Builder Math: What 'Buy 2, Get 1 Free' Really Costs You

Bundles sell — but the discount you hand out hides in the fine print. This calculator breaks down any bundle deal (Buy X Get 1 Free, percent-off, or fixed-price) into the numbers that matter: effective discount, profit per bundle, and exactly how much extra volume you need to come out ahead.

Plug in your cost and price — the widget runs on your numbers only, remembers them on your device, and never sends them anywhere.

How to Use This Widget

Objective: Price bundle deals that grow revenue without quietly eroding your margin.

Desktop: Fill the input card, pick a deal type, and watch every output and the verdict card update live.

Mobile: Work through the full-size input fields, then scroll to the verdict card for the go/no-go call.

What the outputs mean: The verdict card grades your deal — green light (low lift needed), amber (aggressive but workable), red (loses money at any sane volume).

Tips:

• If profit per bundle drops to zero or below, no volume saves the deal — raise the price or shrink the discount first.
• A 30% lift target is the sane green zone for most stores; amber means the deal needs a serious sales plan.
• Use Copy Results to save each scenario before you tweak the numbers.

Run the numbers before you run the sale — your margin will thank you.
