When planning your annual marketing budget, how do you decide how much to allocate to short-term sales promotions versus long-term brand-building activities?

Situation

As a brand manager for a milk brand, I had to propose the annual marketing budget one year when sales targets were aggressive, and the sales team pressured me to put 80% into below-the-line promotions like price-offs and bundle deals.

Task

I needed to defend a balanced budget that protected our brand health scores while still supporting the business's short-term revenue needs.

Action

I analyzed 3 years of sales data and brand tracking metrics, showing that during quarters where promo spend exceeded 60%, our baseline sales eroded and brand preference dipped. I proposed a 55/45 split: 55% for brand-building (a new 'Family Nutrition' advocacy campaign with digital content and school partnerships) and 45% for trade promos and consumer discounts, but linked them to a loyalty app to capture first-party data. I created a 'waterfall' model projecting that while the brand spend would only show immediate ROI after 6 months, it would lift baseline sales by 8% in the next year, justifying the investment.

Result

Management approved the split after seeing the correlation data. Over the year, the advocacy campaign generated 10 million organic video views, brand preference rose by 4 points, and the loyalty app sign-ups provided enough data to reduce promo waste by 12% in subsequent campaigns.
