How it is computed
Take net profit for the period. Divide by total gross profit for the same period, every department included. Multiply by one hundred. Expense to gross is the rest: total expense over total gross.
Why it matters
A net number by itself cannot tell you whether the store earned it or borrowed it. A strong net on a weak net-to-gross means the month was carried by one department or one event; a modest net on a strong net-to-gross means the structure is right and volume is the lever.
It is the discipline number for expense. Gross can grow and net can shrink in the same month, and net to gross is the first place that shows.
How operators read it
- Read it beside absorption. Absorption says whether the fixed side carries the building; net to gross says whether the building keeps what it makes. A store needs both.
- Decompose a move. When net to gross falls, either gross fell with expense flat, or expense rose with gross flat, and the two call for different people in the room.
- Hold the statement to one definition. Where a store books pack, doc fee, and manufacturer money changes both the numerator and the denominator, so compare a store to itself before comparing it to anyone.
Questions people ask
Is net to gross the same as net profit margin?
No. Margin is net over sales. Net to gross is net over gross profit, which strips out the cost of the vehicles and leaves the part of the business the store actually runs.
Which departments count?
All of them. Net to gross is a rooftop number. Department-level versions exist and are useful, but the one the dealer steers by is the whole building.
How A.D.A.M. reads it
A.D.A.M. follows the dealer's own financial north star and offers net profit decomposed into net to gross and expense to gross as the proposed default, never imposed. He reads it beside the numbers it trades against, names what the gap is worth, and leaves the decision where it belongs. What an AI advisor should do, and refuse to do.
