The break-even point of a job — the minimum price below which you stop earning and start losing — is a figure many small firms know roughly, but rarely calculate precisely for each individual job.
What break-even actually includes
Break-even is not only the cost of materials: it includes direct labour, the share of fixed costs and borrowing that job absorbs, and, where appropriate, a buffer for surprises. It is the real total cost, not just the most visible component you bought.
Why knowing it changes the negotiation
Knowing exactly where break-even sits lets you negotiate a discount knowingly: down to a certain level you are still earning; below it you are working at an outright loss. Without that precise figure, every concession is a gamble rather than an informed decision.
A floor, not a target
Break-even is the absolute minimum, not the price to aim for. Using it as a routine reference in negotiations, rather than as an exception for the hardest situations, erodes the firm's average margin over time — keep it in mind, but do not let it become normal practice.
