How many extra units must a 7-Eleven marketing budget sell to pay off?
Short answer: The extra units you need to sell equal the total added marketing budget divided by the incremental profit per unit that whoever pays actually receives. Then convert that into sales per store per day. If the result is several times your current sales, the budget is too big for a first round.
The Flowup team uses this formula in client proposals before discussing creators or ads, because the first question from brand owners and distributors isn't "how many views will we get?" but "how much more do we have to sell not to lose money?"
The formula
Extra units needed = total added budget ÷ incremental profit per unit
- Total added budget includes service fees, ad spend, creator fees, content production, and any extra discount cost the campaign causes.
- Incremental profit per unit is the money the brand or distributor gains from selling one more unit, after product cost and costs that rise with sales. It is not the retail price.
The most common mistake is dividing by the retail price. Hypothetical example: a product selling at 25 baht may leave the brand only a few baht of incremental profit. Divide by 25 baht and the number of units you need looks several times smaller than it really is.
A hypothetical example
A three-month first-round budget of 600,000 baht, with the product in stock in 2,500 stores (all figures hypothetical).
| Incremental profit per unit | Extra units needed | Per store per day (90 days) |
|---|---|---|
| 4 baht | 150,000 units | about 0.67 units |
| 8 baht | 75,000 units | about 0.33 units |
| 12 baht | 50,000 units | about 0.22 units |
If current sales are 0.3 units per store per day, the first row means more than doubling sales in three months, which is a very hard target. The last row means adding about 70%: still hard, but worth discussing.
How to read the result and decide
- Target too high: cut the first-round budget, or work only in areas already selling well.
- Target plausible: set a mid-way indicator, such as sales per store per day in the advertised areas at week 4.
- Target very low: check again that all costs are included. If they really are, you may be able to increase the budget next round.
What the formula leaves out
- Long-term effects. Shoppers who try the product and come back after the campaign ends fall outside the first three months.
- Negotiating leverage. Better sales per store make it easier to discuss more space or new SKUs.
- Delisting risk. If you do nothing, the cost of losing the shelf may be higher than the marketing budget.
Write these up separately as supporting reasons. Don't add them into the formula, or break-even will look easier than it is.
Who should do the calculation
If the brand and distributor share the budget, each has a different incremental profit per unit. Calculate two separate sets, then discuss who gains more from the extra sales. This helps agree budget shares faster.
Limits
- Figures in the table are hypothetical and only show the method
- The formula works best for products with baseline sales; a newly listed product needs two or three weeks of data first
- Proving that extra sales came from marketing needs a comparison area, not just a before-and-after view
FAQ
Can I use TikTok ROAS instead of this formula? No. ROAS measures online sales the platform can track; 7-Eleven in-store sales don't enter that system.
What if I don't know incremental profit per unit? Ask the distributor for the price structure, then subtract product cost, delivery and discounts that rise with sales. If unsure, calculate three levels.
How big should a first-round budget be? It depends on current sales and store count. Use this formula backwards to find the budget level whose target is realistic.
