Ghost Costs that Eat the Money Before it Reaches You
Ghost Costs that Eat the Money Before it Reaches You
In a perfect world, every dollar of sales contributes a predictable amount to your overhead. In the real world, your Contribution Margin is under constant attack.
The problem? Most of these attacks don’t show up as line items on your P&L. They are “Ghost Costs”—the money you should have made but didn’t.
If you want to move your Break-even point closer to reach, you have to plug these four specific leaks:
1. The Material Thief (Scrap & Rework)
Scrap is defined as unusable material discarded during production, including raw materials, work-in-process (WIP), or finished goods that fail to meet quality standards.
While some material loss such as metal shavings, sawdust, trimmings, or standard testing units is considered inevitable, scrap can become excessive if not monitored.
By increasing variable costs, excessive scrap reduces contribution margin and increases break-even level of sales, i.e. you need to sell more to reach break-even point.
The Accounting Trap
Most companies treat scrap as a cost of goods sold. But they forget that scrap also consumed electricity, machine time, and labor hours that can never be recovered.
The Strategic Fix
Track the “Yield” per batch. If your yield is 92%, you aren’t just losing 8% of the material; you are losing 8% of your total factory capacity.
2. The Clock Thief (Machine Downtime)
Unexpected and unplanned machine downtime affects production schedule, lowering output and sales.
In addition to loss of sales, it can also typically involve unplanned costs like:
Idle labor costs as employees still have to be paid even though they are not producing goods
Emergency repairs and cost of expensive spares because unplanned downtime typically occurs owing to machine problems
Overtime pay needed to make up for lost production
The resulting increase in fixed costs pushes up the break-even point.
The Reality
If your Break-even math assumes 8 hours of production, but a machine is down for 2 hours due to poor maintenance, your Break-even volume for that day just jumped by 25%.
The Strategic Fix
Start measuring OEE (Overall Equipment Effectiveness). It bridges the gap between the shopfloor and the ledger.
3. The Ghost Thief (Stockouts & Backorders)
3. The Ghost Thief (Stockouts & Backorders)
Stockout costs are the direct and indirect expenses incurred when a business runs out of inventory and cannot fulfill customer demand.
Stockouts increase the breakeven point because they raise fixed operational costs (emergency shipping) and reduce the contribution margin per unit (due to lost sales), requiring the company to sell more units to cover its expenses.
The Cost
When you run out of stock, you don’t just lose a sale; you lose the “Contribution Margin” that was supposed to pay your rent.
Even worse, you often spend extra money on “expedited shipping” to fix the mistake, which kills the margin on the next sale too.
The Strategic Fix
Balance your inventory “Safety Stock” against the cost of capital. Being “too lean” is sometimes as expensive as being too heavy.
4. The Complexity Thief (The “Yes” Trap)
4. The Complexity Thief (The “Yes” Trap)
Every time a salesperson says “Yes” to a custom request without checking the cost of the changeover, a leak is created.
Custom orders typically raise the break-even point by increasing variable costs (e.g., specialized labor, unique materials).
While they often command a higher selling price, the added complexity can lower the contribution margin per unit if costs rise faster than revenue, requiring more units to be sold to cover fixed costs.
The Cost
Changing a machine setup for a small, “special” order creates massive downtime.
The Strategic Fix
Implement a Minimum Order Quantity (MOQ) that is mathematically tied to your setup costs. Use AI tools to compute and update the MOQ.
If the margin on the special order doesn’t cover the setup “leak,” it’s a losing deal.

Management Accounting isn’t just about recording what happened; it’s about identifying what should have happened but didn’t.
