⚠️ Margin under 10% leaves no room for surprise expenses or downturns. Look at the highest cost line — that’s where the win is.
What healthy garage numbers look like
Margin: 15–25%
Industry-standard healthy net margin. Below 10% is a warning sign — one slow month and you’re negative.
Parts: 25–40% of revenue
If parts cost is 50%+ of revenue, your markup is too low. Renegotiate with suppliers or audit which jobs you accept.
Salaries: 30–40%
Above 45% means under-utilised technicians. Either fill more bays or reduce headcount before profit collapses.
