How Co-op Accrual Actually Works

Accrual is the rule that turns a dealer's purchases into advertising money. It is the single most important parameter in a co-op program, and the one most often left vague. Here is how the three common models work, what the published plans actually use, and why the choice changes how the program feels to the people spending against it.

The three models

Percentage of purchases

The dealer earns a fixed percentage of what it buys from the manufacturer, usually measured on net invoiced purchases over a calendar or program year. Buy $200,000 of product at a 3% accrual and you have $6,000 of co-op to spend. This is the dominant model. Of the 1,286 manufacturer plans in our database that publish real terms, just over half key accrual to purchases. The most common published rates are 2%, 3%, 5% and 1%, in that order. A handful of premium categories run higher: beauty products average above 10%, and several jewelry brands pay 10%.

Per-unit

A flat dollar amount for each unit sold or purchased. Common in vehicles, powersports, appliances, and anywhere a unit is expensive enough that a percentage would swing wildly with price. One automaker in the data describes it plainly: a standard contribution of 1% of adjusted MSRP on every new vehicle, calculated monthly and funded by the 15th of the following month. Per-unit accrual is easy to audit and easy for a dealer to forecast.

Flat allocation

Corporate sets a dollar budget per location or per tier at the start of the year, independent of purchases. About one plan in fourteen works this way. It is the simplest to administer and the right choice when local marketing is a brand-standard obligation rather than a reward for volume, which is why franchise systems lean on it.

What the plans say about timing

Accrual is only half the formula. The other half is when the money shows up and when it disappears.

• Prior-year basis. Roughly one in eight plans calculates this year's fund from last year's purchases. Dealers know their budget on January 1, but new accounts start with nothing and fast-growing accounts are always a year behind.
• Current-year basis. The fund grows as purchases post, monthly or quarterly. It rewards growth immediately but makes budgeting a moving target.
• Use it or lose it. Forty-three percent of plans with terms state that unused funds do not carry over. Combined with a 60-day claim window, which is the single most common deadline in the data, that produces the familiar fourth-quarter scramble.

Why the formula changes behavior

A percentage model tells dealers that advertising money is a reward for buying more. A per-unit model tells them it is a cost of doing business built into each sale. A flat allocation tells them corporate expects a certain amount of local activity regardless of volume. Each is a legitimate design, but they produce different dealer behavior, and mixing them across tiers without saying so is where confusion starts.

The practical test is whether a location manager can look at a balance today and explain where it came from. If the answer requires a spreadsheet from the regional rep, the formula is too complicated or the data is arriving too late. Modern platforms solve the second problem by computing accrual automatically from purchase data as it posts, so the balance a dealer sees is always current. Co-Op Command supports percentage, per-unit, and flat allocation, with the formula and its funding period set once per program and applied to every location.

A checklist for writing the rule

1. Name the basis: net purchases, gross purchases, units, or a fixed allocation.
2. Name the period: prior year, current year monthly, or current year quarterly.
3. State the rate or amount, and whether it varies by tier.
4. State the expiration: carryover allowed or not, and the cutoff date.
5. State the exclusions: parts, closeouts, discontinued lines, and product categories that do not earn.

Five sentences. If your current program document takes five pages to say the same thing, that is the first thing to fix.
