In the first year of a new production line's operation, the income statement often looks weak. The CEO's first thought is usually insufficient orders, followed by poor management. The real reason is simpler: depreciation starts in the month production begins, but it takes six to twelve months for orders to reach design capacity. These two timelines don't align.
1. Depreciation is a function of time, not orders.
Under the straight-line method, equipment depreciation is allocated evenly to cost on a monthly basis, regardless of whether the production line operates at full capacity. For a $30 million production line with a 10-year depreciation period, the monthly depreciation is fixed at $250,000. In the early stages of operation, when output reaches only 40% of design capacity, this $250,000 is spread over fewer units, making the depreciation cost per unit nearly 2.5 times higher than at full production.
This isn't an accounting issue; it's a decision-making one. If leadership doesn't understand this mechanism, they'll cut back at the worst possible time.
2. Order structure amplifies the mismatch
New lines often start with small-batch, high-mix trial orders. Frequent changeovers fragment productive time, and yield is still ramping up. Depreciation combined with changeover losses drives up unit costs on both fronts. Evaluating a new line using the cost standards of an established line will inevitably conclude it is uneconomical.
3. Reports must be viewable separately
Recommend calculating costs per production line separately, tracking at least three key metrics: line depreciation, direct labor and energy consumption for that line, and the line's yield rate. Plot the ramp-up curve and mark the projected month when design capacity is reached. This provides a clear explanation for "Year 1 losses" and establishes a defined observation window.
4. Three Decision-Making Reminders
First, investment projections must include fixed costs during the ramp-up phase, not just unit costs at full capacity. Second, for the first six months before new line acceptance, evaluate based on contribution margin rather than net profit. Third, if ramp-up lags significantly behind plan, determine whether the issue stems from market conditions or process limitations, as the responses differ substantially.
Clarifying the time gap is far more useful than blaming losses on "a bad industry."
