Should You Drop Your DRP? Run This Number First

Every DRP conversation I have with a shop owner eventually lands on the same fear. If I walk away from the program, the cars stop coming, and I never find out whether my shop could have survived without it.

The public version of this argument runs on conviction. Keep the volume. Fire the insurer. Both camps sound certain, and neither one has seen your books. So here is the model I actually use with clients, complete, including the adjustments that don't fit in a two minute video.

Work in dollars, not percentages

A concession cuts your bill and your margin at the same time. The labor discount, the parts caps, the scans and calibrations you eat, each one reduces what you collect on the same physical work while the cost of the repair stays put. If you compare margin percentages between your program work and your door work, you under-count the damage, because the smaller percentage is also being applied to a smaller bill.

So the model runs on one unit: contribution dollars per car. What does a program car actually leave you after every giveback, and what does a door car leave you at your posted rates?

The model

Take a shop running a hundred DRP cars a month through one program. Average RO three thousand dollars. After concessions, gross profit on that work runs 38 percent. Each car contributes about $1,140, call it $114,000 a month, toward rent, payroll, insurance. The bills that don't care where the car came from.

Now price the same car at the door rate. It bills about $3,250, and without the concessions gross profit runs 44 percent. That's about $1,430 a car.

The break-even retention rate is just the ratio of those two numbers. $1,140 divided by $1,430 is right around 80 percent. If at least eight of every ten of those cars would still find you without the program, through your reputation, your certifications, your referral base, walking away pays you. If fewer would, the program is funding your fixed costs, whatever the rate sheet looks like.

Those numbers are illustrative. Your concessions, your rates, your market. The mechanics are what transfer.

The flip

Some shops run better margins on their program work than on their door work. I've seen it more than once. Program steering can send lighter hits with faster approvals, while door work skews heavy, slow, and discount-prone. If that's your shop, the ratio comes out at or above 100 percent, and the math ends fast. Keep the program. Anyone telling you otherwise is arguing ideology, not arithmetic.

One caution when you check this on your own books: the two books carry different job mixes, so the comparison is directional, not surgical. Use each book's own actuals and don't chase false precision.

The adjustments the short version skips

Storage and total losses play differently under a program. DRP terms often waive or cap storage and move total losses through fast. Door-work total losses can carry real storage revenue but settle slower and collect harder. With total losses running at roughly a fifth of claims, a shop with heavy total-loss intake should price that difference into the absorption number before trusting the ratio.

Your market sets the retention number

The break-even rate tells you the hurdle. Your competitive landscape tells you whether you can clear it. The only quality shop for thirty miles keeps more of its cars than one of six on the same road, because steering wins more of the coin flips where the customer has easy alternatives. Be honest about which market you operate in when you pick your retention estimate. That honesty is the difference between a decision and a wish.

What this number doesn't decide

The ratio answers one question: does the program pencil on margin and absorption? It doesn't price your capacity, your cycle time exposure, or what the program does to your shop's sanity. Those belong in the conversation after the number, not instead of it.

Run it for your shop

I built a calculator that runs this whole model in about a minute with rough numbers: collisionadvisory.com/tools/drp-break-even. If you'd rather have the printable one page worksheet for a sit-down with last month's statements, message me on LinkedIn and I'll send it over, or get on my Friday email list at collisionadvisory.com/subscribe and reply with the word DRP.

Most owners have never run this number, so the keep-or-drop call gets made on fear instead of arithmetic. Both sides of the public fight are right, for different shops. The answer is your ratio, and it's different shop to shop.
