Order bump and upsell revenue calculator: added revenue per 1,000 orders

The short answer: on SamCart's own published example, one bump and one upsell lift AOV by about 26%, which works out to roughly $24,900 of extra revenue per 1,000 orders with no extra ad spend. Your figure depends on your prices and take rates, so run your own numbers below.

How the calculator works

The model takes the expected value of each paid front-end order. Every buyer pays the main price. A share of them, equal to your bump rate, also pays the bump price, and a share equal to your upsell rate pays the upsell price. So the new average order value is the front-end price plus bump rate times bump price plus upsell rate times upsell price, and the added revenue is that extra amount multiplied by your order count.

It is a planning estimate and makes three simplifications. Every order you enter is treated as a completed main sale, so checkout abandonment is outside the model. The bump and the upsell are treated as independent, which means a buyer can take one, both or neither. And it models one bump and one upsell: a second bump, a downsell after a declined upsell, or a longer chain of offers would each need a line of its own. The default prices and rates come from the expansion-revenue example on SamCart's blog, which is the vendor's own data from its sellers. SamCart publishes a revenue calculator of its own, and this one is separate from it.

Worked example: ten buyers, then a thousand

SamCart's example starts with ten buyers of a $97 product, $970 in all. Four of them tick a $27 bump at checkout, adding $108. Three of them accept a $47 one-click upsell after paying, adding $141. The ten orders now total $1,219, an average order of $121.90 and a lift of about 26%.

Scale the same rates to 1,000 buyers and the bump brings in $10,800 while the upsell brings $14,100. Together that is $24,900 the front-end offer alone would never have collected, from traffic you already paid for.

Our order bump vs one-click upsell comparison runs a second version of the same math with a $67 upsell instead, which is our own arithmetic and not SamCart's. At the same two rates, AOV reaches $127.90 and 1,000 orders add $30,900. The upsell price moved more money than anything else on the page, which is why the comparison covers when each offer belongs in a paid-traffic funnel.

Which take rates and prices to enter

SamCart reports that 31% to 42% of its buyers take an order bump and 20% to 35% accept a one-click upsell. Those bands come from one vendor's transaction data and we found no independent benchmark to check them against, so use them as a first guess and replace them with your own checkout reports once the offer is live.

On price, SamCart's order bump guide advises setting the bump at 20% to 40% of the main product. Its expansion-revenue table puts typical bumps between $7 and $47 and upsells from $47 up past $297. A cheap, closely related bump keeps the checkbox an easy yes, while the upsell page has the buyer's full attention and can carry a bigger ticket.

Placement changes the rate as well. One seller posted on Reddit that moving the bump below the submit button doubled their take rate. It is a single unconfirmed report, but it is a cheap test to run on your own checkout.

What to build first

My take: if I could build only one before November, I'd build the bump. Which carts put a checkbox on the checkout, and on which plan, is in order bump software. It sits on the page that already converts, it needs no extra page design, and it adds revenue on the first sale. I'd add the upsell once the checkout is stable, then judge the next test by added revenue per 1,000 orders from your real rates, not by take rate alone. Our guide to checkout split testing software covers which carts can test bump placement on the checkout link your ads already use. Which checkout tools ship both features on their entry plans is covered in our SamCart review and the wider checkout software rankings, and how we evaluate checkout tools explains the research behind both. Sellers on a high-risk processor should also read about high-risk merchant account providers, since an upsell bills the stored card a second time on the same account.
