The question it answers
Are our larger packs priced consistently against our smaller ones, and against the market?
Account Brand Price Slopes fits base price per ounce against pack size for each brand line, comparable-product group and banner. It reports the discount for each doubling of pack size against the market curve, and flags items more than 10% off their brand's curve and larger packs priced higher per ounce than smaller ones.
Why it matters
Shoppers expect a larger pack to cost less per ounce. When it does not, the pack stalls or the smaller one sells for the wrong reason. These inconsistencies build up one price change at a time and are hard to see in a price list. A fitted curve shows at a glance which items are out of line and by how much.
How it works
- Inputs
Licensed syndicated base shelf price and pack size by item and banner over a four-week period, with comparable-product groups from Alakai's mapping layer.
- Analysis
A curve is fitted for each brand line and compared with the market curve. Sub-lines sit on their own curves, so flags reflect pricing, not product mix.
- Outputs
Slope per brand line, off-curve flags, ladder inversions and the change since the prior period.
What you get
Discount per doubling
How much price per ounce falls each time pack size doubles, against the market.
Off-curve flags
Items more than 10% above or below their brand's curve.
Ladder inversions
Larger packs priced higher per ounce than smaller ones.
Period change
How each rate moved since the prior period, where history is licensed.
Example in action
Illustrative scenario
Across the banners you follow, most slopes sit close to the market. At one, your brand's slope shows a shallower size discount. One mid-size pack sits well above the curve, and the largest pack costs more per ounce than the one below it. The team corrects the inversion first, then reviews the mid-size price.
Questions
- How many pack sizes are needed?
- A curve needs three comparable sizes, and off-curve flags need a reasonably good fit. An inversion check needs only two sizes.
- What happens to items with a missing price or size?
- They are excluded. Values are never imputed.
- Are promotional prices included?
- No. The analysis uses base shelf price. Promotional and realized prices are out of scope, and nothing is sized by sales volume.
- Is there a limit on brands, competitors or banners?
- No. Follow as many as you need. Pricing scales with the coverage you configure.
