💡 Accountant's Note
Service and parts gross profit as a percentage of total dealership overhead is called 'absorption rate.' A 100% absorption rate means the dealership's fixed operations pay all of the dealership's overhead — the vehicle sales departments operate at pure profit. Absorption is a key metric in automotive retail — dealers target 70-100%+ absorption. This is a management reporting metric, not a specific accounting entry.
Practitioner & Systems Framework
💻 ERP Architecture
Absorption is calculated in the dealership's management reporting system (often a dealer 20 Group composite or DMS management reporting module). Fixed operations gross profit = service labor gross profit + parts gross profit + body shop gross profit. Total overhead = all fixed expenses (rent, insurance, utilities, administrative salaries, advertising, floor plan interest). Absorption % = Fixed Ops Gross / Total Overhead × 100. A high absorption rate provides resilience during vehicle sales downturns — dealerships with 100%+ absorption remain profitable even if vehicle sales decline significantly. Manufacturers often publish absorption benchmarks for their dealer network.
⚠️ Audit Flags
This is primarily a management reporting metric rather than an auditable accounting entry. Auditors reviewing the dealership's overall financial performance should confirm that the components of fixed operations gross profit and overhead are correctly classified in the DMS chart of accounts — misclassification of selling expenses as overhead (inflating the overhead base) would distort the absorption calculation. Review whether management compensation is appropriately allocated between sales and fixed operations.
