Does bundling two products lose me money compared to selling them separately?

Bundles are popular. Two items for one price feels like a bargain to the buyer and a tidy way to move stock for the seller. But a discount has to come from somewhere. The question is whether it comes out of your profit, and whether the extra sale is worth it.

The two products

Use illustrative figures.

• Item A sells for Rs 300 and costs you Rs 120.
• Item B sells for Rs 200 and costs you Rs 80.

Sold separately

• Item A profit: Rs 300 minus Rs 120 is Rs 180.
• Item B profit: Rs 200 minus Rs 80 is Rs 120.
• Total revenue: Rs 500. Total profit: Rs 300.
• Margin: 300 divided by 500 is 60 percent.

Sold as a Rs 450 bundle

• Revenue: Rs 450.
• Cost: Rs 120 plus Rs 80, which is Rs 200.
• Profit: Rs 250.
• Margin: 250 divided by 450 is about 55.6 percent.

The bundle gives up Rs 50 of profit compared with the separate sale, and the margin slips from 60 to 55.6 percent. So yes, on this one comparison, the bundle earns less.

But that is not the whole story

The comparison above assumes the customer would have bought both items separately anyway. Often they would not. The honest question is what the bundle changes:

• If a customer would have bought only item A, the bundle adds item B. You earn Rs 250 instead of Rs 180. That is a gain of Rs 70.
• If a customer would have bought both anyway, the bundle costs you Rs 50.
• If a customer would have bought nothing, the bundle brings in Rs 250 that you would not have had.

So the bundle wins when it mostly attracts people who would not buy both, and loses when it mostly discounts people who would. You can only learn this by watching real orders, not from a spreadsheet.

Shared costs can tilt it your way

A bundle also saves on costs the spreadsheet above ignores. Two items in one parcel need one box, one label and one shipment, not two. If packing and shipping together cost Rs 100 for two separate parcels and Rs 60 for one bundled parcel, you save Rs 40, which erases most of the Rs 50 discount. See packaging cost per order and shipping weight slabs for how to count those.

Useful rules of thumb

• Bundle items that people naturally use together, so the offer feels sensible.
• Put a slower-moving item with a popular one to clear stock, as long as the combined margin still works.
• Know your minimum acceptable margin before you set the discount. Our post on the maximum bundle discount from cost shows how.
• Keep the bundle price clear so the saving is obvious. The thinking in price anchoring helps you present it.

Track the result

After a month, compare orders that contained the bundle with orders that did not. Did average order value rise? Did stock of the slower item move? Did total profit go up, even if margin per order fell?

The takeaway

A bundle usually lowers margin per sale. It can still raise total profit if it brings extra sales or saves on packing and shipping. Do the arithmetic before you launch, and review it once real orders come in.
