Upselling Impact Calculator

Because it repeats across every cover. Adding an average of less than a euro to each check sounds trivial, but a restaurant serving thousands of covers a month multiplies that small amount thousands of times. This calculator shows how a single add-on, accepted by only a third of guests, can compound into tens of thousands of euros of incremental margin a year with no extra footfall and almost no extra cost.

The acceptance rate is the share of guests who actually take the upsell when offered. If staff suggest a coffee and 35% of tables say yes, the effective increase per cover is the upsell price multiplied by 0.35. The acceptance rate is the single biggest lever you control through staff training and menu prompts, which is why the calculator keeps it separate from the upsell value.

First the effective uplift per cover = upsell price x acceptance rate. Multiply that by your monthly covers to get incremental revenue, then apply the margin on the upsold item to get incremental margin. High-margin items like coffee, desserts and wine by the glass produce the strongest results because almost all of the extra revenue falls through to profit.

Because the add-on is usually a high-margin product. A coffee or a glass of wine carries a far higher margin than the average dish, so applying the item margin (often 80-90%) rather than the venue average gives a realistic, and usually larger, picture of the profit the upsell creates.

Train staff to suggest a specific item at the right moment (a dessert after mains, a coffee before the bill), keep the prompt simple, and make the item easy to say yes to. Even a few percentage points of extra acceptance, multiplied across all covers, move the annual figure noticeably; use the calculator to model the effect before and after training.
