What is base gross profit? The threshold for promotion profitability
· 5 min read · CollMind
If you ran no promotion, how much money would be left on the table on a normal day, after everything is paid? The answer to that question is base gross profit, and it is the threshold against which every promotion decision should be measured.
Trade marketing teams often evaluate campaigns by volume and revenue. Yet a campaign that increases volume but pulls profit below its normal level costs the company money, even if it looks successful. In this post we explain what base gross profit is, how it is calculated and how to use it in promotion decisions.
What is base gross profit?
Base gross profit is the profit left from baseline sales, when there is no promotion, after the cost of goods is deducted.
Base Gross Profit = Base Net Revenue − Base Cost (COGS)
This definition relies on several KPIs that come before it. To calculate base gross profit correctly, you need to build the chain from the start.
The chain: from base volume to base gross profit
1. Baseline sales volume. The estimated number of units that would sell without a promotion. This is the foundation of the whole calculation. For details, see our post What is baseline sales volume?
2. Base gross sales value (Base GSV). The gross revenue that would be earned if the baseline volume were sold at list price, without any discount.
Base Gross Sales Value = Unit List Price × Baseline Sales Volume
This is the “perfect world” scenario and the starting point for understanding how much each discount takes away from potential revenue.
3. Base net revenue (net sales without promotion). In real life, nothing is sold at list price; there are standard dealer discounts, fixed agreements and routine deductions. Base net revenue is the net income left after these are deducted.
Base Net Revenue = Base Gross Sales Value − Base Trade Spend
4. Base gross profit. In the last step, the cost of goods for baseline sales is deducted. The remaining amount is the profit you earn in a normal period without a promotion.
Step-by-step example
Assume a product with a list price of TRY 10 sells 1,000 units a month without a promotion. The standard dealer discount is 10 percent and the unit cost is TRY 5.
| Step | Calculation | Result |
|---|---|---|
| Baseline sales volume | Estimate | 1,000 units |
| Base gross sales value | TRY 10 × 1,000 | TRY 10,000 |
| Base trade spend | 10% standard discount | TRY 1,000 |
| Base net revenue | 10,000 − 1,000 | TRY 9,000 |
| Base cost | TRY 5 × 1,000 | TRY 5,000 |
| Base gross profit | 9,000 − 5,000 | TRY 4,000 |
Your normal profitability level for this product is TRY 4,000 a month. Every promotion you plan should increase this TRY 4,000. If it does not, you should be doing it for a deliberate, strategic reason.
How is it used in promotion decisions?
Say you are planning a 20 percent price discount for the same product and expect sales to rise to 1,500 units. Volume will grow by 50 percent; that sounds great. But let’s look at the profit side:
- New net price: applying the 20 percent promotional discount to the list price (TRY 8) and then the 10 percent standard discount gives TRY 7.20 per unit.
- Promotion revenue: 1,500 × 7.20 = TRY 10,800.
- Promotion cost: 1,500 × 5 = TRY 7,500.
- Gross profit for the promotion period: TRY 3,300.
Volume grew by 50 percent, but gross profit fell TRY 700 below the base level (TRY 4,000). Without the base gross profit threshold, this campaign would probably have been reported as a “success”.
This comparison clarifies three questions in promotion decisions:
- Does the campaign increase base gross profit?
- If not, is there a strategic gain in return? (Such as reaching new customers, responding to a competitor’s launch or driving trial.)
- Is there another mechanic that could increase base profit with the same budget?
Base gross profit and ROI
The “incremental profit” used when calculating promotion return on investment (ROI) is in fact the difference between gross profit for the promotion period and base gross profit. In the example above, this difference is minus TRY 700; in other words, every lira spent on the promotion led to a loss instead of coming back to the company as profit. ROI calculations made without calculating base gross profit correctly show promotions as either better or worse than they really are. That is why base gross profit is the quiet but indispensable partner of ROI analysis.
Common mistakes
- Evaluating the campaign by revenue alone. Revenue growth can hide a loss of profit.
- Skipping base net revenue. A calculation that does not deduct routine discounts overstates normal profitability and makes promotions look unfairly bad.
- Forgetting extra logistics and display costs. Campaign-specific costs such as inserts, stands and extra shipments should be deducted separately from promotion profit.
- Looking at a single product. If there is cannibalization, the comparison should be made with base gross profit for the category as a whole.
Conclusion
Base gross profit is the threshold for promotion profitability. When baseline volume, base gross sales value and base net revenue are built correctly, you can clearly see which campaigns create value and which only buy volume.
Trade promotion management software calculates this chain automatically for every customer and product, shows the base profit threshold at the planning stage and compares it with actuals after the campaign.
Ask yourself: When you plan a promotion, do you use your normal profitability level as a threshold?
