There’s a 16-oz. box of branded rotini pasta on the store shelf. It’s one thing to discover when, where, and how that box was purchased, but what if the manufacturer and retailer could learn how the product was used when the shopper brought it home — whether it ended up in pasta salad, a dish with bolognese sauce, or part of a macaroni-and-cheese casserole?
Now, CPGs and merchants can get such crucial, actionable information. New consumer and market research capabilities extend beyond the midpoint moment of purchase to cover the later points that truly reflect users’ needs and preferences and help brands and retailers optimize occasion dollars by turning eating and drinking moments into measurable market opportunities.
Circana’s recently-launched Purchase to Consumption solution tracks the “secret life of groceries” as products move from the physical or digital shelf to the consumer kitchen, pantry, table, car, office, and then onto the waste basket and recycling bin.
Until now, CPGs and merchants in the U.S. have not been able to get past traditional blind spots and connect what the shopper buys with when, where, and how it is consumed. In addition to discovering what went into the cart through consumer data, they can benefit from data that shows what role those products played in real life with consumption data
The Journey You Never See
Although the receipt records a transaction, it only tells the first part of the shopper story. Take a bag of shredded cheese, for instance. Purchased on a Saturday, it does not serve a single purpose. Over the following days it appears in scrambled eggs at breakfast, melts into a quesadilla for lunch, and finishes as a topping on a weeknight salad. One purchase was used on three distinct occasions, consumed by different household members at different times for different reasons.
Now think about a box of cookies a parent buys with school lunches in mind. The intended use and the actual use don’t necessarily match. By using linked datasets, the brand and seller see that the product is often consumed by an adult who is snacking solo, not as a child’s school treat. The purchase signal pointed in one direction, but consumption reality went another way.
There are plenty of other examples of how product usage has remained invisible to brands and retailers whose bottom lines depend on what happens on the occasions after checkout. This is true across product categories, store formats, and shopper types.
Insight Gaps That Costs Growth
For years, companies measured purchase and consumption as two separate datasets. Purchase data answered one question. It told you what was bought, where, and at what price. Consumption data answered a different question. It told them who ate what, when, and why. Both were valuable, but they were not connected.
The problem was structural. These datasets were never linked to the same consumer. Teams could measure sales volume and eating behavior, but they could not confidently connect the two. They could not say which occasion drove a specific purchase or how consumption behavior shifted from one retailer to another.
Traditional research compounded the problem by relying on memory. Most consumers can’t accurately recall where they bought every ingredient or what each item cost over time. Ask someone to trace the spice they used tonight back to a purchase three months ago, and the answer is a guess. Decisions built on guesses carry a cost, and that cost shows up as missed growth.
Connecting Purchase to Consumption
The Purchase to Consumption solution closes these gaps by linking two proven sources of data from the exact same consumers. It connects Circana’s verified receipt panel purchase data with its National Eating Trends (NET®) consumption behaviors. A subset of the receipt panel also participates in the NET consumption diary, creating a single connected view of what a person buys and how they actually use it.
Rather than depending on recall, this tool traces an ingredient bought a few months ago to its exact purchase origin and price point. The spice used at dinner tonight can be linked to the transaction that brought it home, along with what it cost. The result is a continuous, accurate account of the path from cart to plate, with a mix of consumer feedback and purchase data.
Spotlight on Occasion Dollars
The most practical outcome of this new capability is a metric that translates behavior into money, otherwise known as occasion dollars. This ties each consumption occasion to the actual price paid by the consumer.
The numbers make the value concrete. The average consumer spends $3.78 per person on an at-home dinner occasion, and that spend increases by17% when guests are present for dinner. The outlay spikes by 36% when guests are present across all day parts, Small shifts in occasion type, then, carry real financial weight, and occasion dollars let teams size and prioritize those shifts rather than debate them.
The retailer's opportunity is equally direct. Analysis shows that four of the top 10 retailers are failing to capture their fair share of at-home dinner dollars, representing a combined opportunity of more than $100 million. Part of the reason is that the average dinner is sourced from two different retailers, meaning meal occasions are routinely shared with competitors. Knowing where those dollars leak is the first step to recovering them.
These insights rest on robust data. Circana’s research captures more than 900,000 eating and drinking occasions annually, weighted to the U.S. Census across all ages, and connects roughly $1 trillion in CPG food and beverage purchases to consumption behavior.
From Insight to Action
Visibility only matters when it changes decisions. Tracking groceries from end to end gives brands and retailers a clear path from evidence to action.
For innovation teams, this type of complete information identifies real needs rather than assumed ones. When data shows a growing occasion such as solo snacking or quick breakfasts, teams can build products for observed behavior and reveal white space in the current portfolio. Even the cookie box experience has the potential to unlock new questions.
For merchandising and category teams, having holistic insights allows them to discover how specific shoppers actually assemble meals. Retailers can design aisles and assortments to solve complete meal challenges, close fair-share gaps, and target the high-dollar occasions competitors are winning.
For shopper marketing and brand teams, the complete view sharpens targeting and messaging. Promotions can be tuned to a retailer's real customers using true consumption data, matching offers to the occasions that drive value rather than to broad averages.
The Secret’s Out
For decades, the story of a grocery trip ended at the register. Everything that gave a purchase meaning — the meal, the moment, the member of the household who consumed it — stayed out of view. That missing chapter carried a measurable cost in misread demand and forfeited dollars.
Now available at scale within Circana's Unify+ solution, Purchase to Consumption turns hidden behavior into occasion dollars, sharper innovation, and stronger fair-share strategies.
How Purchase to Consumption Brings The Secret Life of Groceries into the Open
With purchase and consumption bound together, the full context of every occasion becomes visible and measurable. CPGs and retailers across brick-and-mortar and e-commerce channels get the complete set of answers that matter:
Who consumed the product, whether the buyer, a child, or a guest.
What was consumed and how it was combined with other items.
When the occasion occurred, by daypart and day of the week.
Where it happened, in the home, in the car or at work.
Why the occasion took place, from a quick weekday meal to a special gathering.
How the product was prepared, including the use of certain appliances and cooking methods. This context turns behavior into evidence. Brands and retailers stop inferring what shoppers do and start observing it directly. From there, they can make decisions on how to best target and communicate with their customers.
