Sales growth after a discount does not yet mean that the promotion left more money. Compare revenue after refunds with variable costs and the expenses of the promotion itself. If the cost of goods is unknown, the result is still unknown — it cannot be counted as zero.
Illustrative calculation
These are educational numbers, not Boosted data. Before the promotion, 10 units were sold at 1 000 rubles with variable costs of 600 rubles per unit: 4 000 rubles remain before fixed expenses. During the promotion, 15 were sold at 800 rubles with the same costs: 3 000 remain. If an additional 1 000 rubles were spent on placement, the result is 2 000. More sales, less left over.
Do not call this remainder net profit: the example does not account for fixed expenses and other possible obligations. For your own management spreadsheet, define the composition of costs in advance and apply it equally to both periods.
What to include in the check
Record confirmed revenue, cash refunds, the cost of what was delivered, fees, and direct campaign expenses. The discount has already reduced the actual sale price — do not subtract it a second time. A wallet top-up and a subsequent purchase using that balance must not become two sales of the same service.
If some orders are not yet completed or are awaiting a refund, mark the result as preliminary. Compare windows of equal length, but do not forget about seasonality and product mix: a simple before/after does not prove that the discount caused the difference.
Decision after the calculation
With higher turnover and a smaller remainder, check the size of the discount, the composition of the order, and acquisition expenses. If costs are unknown, restore your accounting first. Scaling up the campaign based only on the number of orders is risky for the budget.
