Frequently asked questions

A profit margin calculator is a free tool that helps tradespeople work out the percentage of profit on a job after factoring in labour costs, material costs, overheads, and your service price. It's a quick way to check whether a job is worth doing - but it only works if you input accurate numbers. Fergus automates this by tracking real costs in real time.

No. Installations typically have lower margins (40-50%) due to equipment costs, while service calls and repairs can achieve higher margins (50-65%) since labor is the primary cost.

Review margins on every estimate and calculate actual margins after job completion. This helps you identify which types of HVAC work are most profitable for your business.

Many successful HVAC contractors use flat-rate pricing for service and repairs (allowing for better margin control) and detailed quotes for installations. Both approaches work - choose what fits your market.
