Why “True Cost Per Bale” Is Different From What Most Farmers Calculate
The Gap Between Perceived Cost and Actual Cost
When farmers estimate their cost to produce a пресс-подборщик силоса bale, the most common approach is to add up the cash costs that appear on receipts — film, fuel, and perhaps repairs — and divide by the number of bales produced. This calculation typically produces a number in the range of $8–20 per bale, which seems modest relative to contractor rates of $25–45 per wrapped bale. The conclusion drawn is that owning is clearly more economical than hiring.
The problem with this calculation is that it omits the largest cost components: depreciation of the capital invested in the machine, the interest cost or opportunity cost of that capital, the labour time of the operator, and the maintenance costs that accumulate in irregular lumps rather than smooth per-bale amounts. When these are included, the true cost per bale for a farm-owned silage baler typically ranges from $30–65 per wrapped bale depending on annual bale numbers, machine cost, and the farm’s specific cost inputs. This range overlaps significantly with contractor rates — meaning the ownership economics are more nuanced than a simple comparison of out-of-pocket costs versus contractor invoices suggests.
Understanding the true cost per bale serves two practical purposes. First, it allows a genuinely informed comparison between owning and contracting silage production. Second, it identifies which cost components are largest for a specific operation and therefore where there is the most scope to reduce cost through management decisions — annual bale volume, machine selection, maintenance strategy, and labour efficiency all affect the number significantly.

The Five Cost Components of Silage Baler Ownership
Every Cost That Must Be Included for an Accurate Per-Bale Calculation
1. Depreciation
Depreciation is the largest single cost component for most owned silage balers and the one most consistently omitted from farmer cost estimates. Depreciation represents the loss in asset value as the machine ages and accumulates hours — it is a real economic cost even though it doesn’t appear on a bank statement or tax invoice. A silage baler purchased new for $45,000 AUD and sold after 10 years for $12,000 AUD has depreciated by $33,000 over that period. Spread across 10 years of production, that is $3,300 per year of depreciation — a cost that exists whether the machine balas 50 bales per year or 500.
The practical depreciation calculation for an owned silage baler is: (Purchase price – Estimated resale value at disposal) ÷ Expected years of ownership = Annual depreciation cost. This annual cost must then be divided by annual bale numbers to produce the depreciation component of per-bale cost. A machine depreciated at $3,300 per year producing 100 bales per year contributes $33.00 per bale in depreciation — the same machine producing 300 bales per year contributes $11.00 per bale. This is why annual volume is the single most powerful driver of per-bale cost: it determines how widely each fixed cost is spread.
2. Finance or Opportunity Cost of Capital
Whether the baler was purchased outright or financed, there is a capital cost associated with the funds invested in it. If financed by a loan, the interest payments are a direct cash cost that must be included. If purchased outright with farm funds, the opportunity cost of that capital — what those funds could earn if invested elsewhere — is the relevant cost. Using a rate of 5–7% on the average capital invested is a reasonable approach for Australian farm conditions. For a $45,000 baler with a 10-year life and declining book value, the average capital invested over the ownership period is approximately $28,500 (roughly the average of purchase price and residual value). At 6%, the annual capital cost is approximately $1,710 — equivalent to $17.10 per bale at 100 bales per year or $5.70 per bale at 300 bales per year.
3. Repairs and Maintenance
Repair and maintenance costs for a silage baler in Australian conditions typically average $800–2,500 per year depending on machine age, usage intensity, and silage conditions (wet silage accelerates wear significantly). The challenge with maintenance cost is its irregular nature — years with only routine servicing costs are interrupted by occasional larger expenses from belt set replacement ($500–1,500), bearing replacements ($200–600 per event), knotter rebuilds, and pickup tine sets. Using a 5–10 year average annual maintenance figure rather than the current year’s actual cost gives a more accurate per-bale number that doesn’t swing dramatically between low-cost and high-cost years.

4. Consumables: Film, Twine, and Fuel
Consumables are the most visible and most accurately estimated component of the per-bale cost because they appear on receipts and are proportional to bale numbers. For a standard 1.25m round silage bale wrapped to 6 layers, the typical consumable costs are: stretch film $7–12 per bale (depending on film specification and bale size), twine $0.50–1.50 per bale, and tractor fuel for the baling and wrapping session approximately $1.50–4.00 per bale at current diesel prices. Total consumables per wrapped bale typically range from $9–17.50. This is the range that most farmers estimate as their total cost — in reality it is only one component of a cost that is 2–4× higher when all components are included.
5. Labour
Owner-operator labour is routinely excluded from farm cost calculations on the reasoning that “I was going to be here anyway.” This is a significant accounting error — the opportunity cost of owner labour time is real, whether calculated as the hourly rate paid to employees performing other tasks during the same period or as the market rate for the same activity performed by a contractor. A typical silage baling session for 100 bales takes 8–12 hours of operator time including baling, wrapping, bale handling, and machine preparation. At $35–50 AUD per hour for skilled farm operator time, 100 bales represents $280–600 of labour cost — $2.80–6.00 per bale. This is a cost that contractor rates inherently include; owner-operator calculations should include it for a fair comparison.
Worked Example: True Cost Per Bale at Two Production Volumes
How the Number Changes Dramatically With Annual Bale Volume
The following example uses a mid-range Ever-power silage baler purchased new at $38,000 AUD, with an estimated resale value of $10,000 after 10 years, and typical Australian cost inputs. The same machine is costed at two different annual production volumes — 120 bales per year (small dairy or beef farm) and 280 bales per year (medium dairy farm) — to illustrate the critical role of volume in determining per-bale economics.
| Cost Component | Annual ($) | Per Bale: 120/yr | Per Bale: 280/yr |
|---|---|---|---|
| Depreciation ($38k – $10k ÷ 10 yrs) | $2,800 | $23.33 | $10.00 |
| Capital cost (6% on avg. $24k invested) | $1,440 | $12.00 | $5.14 |
| Repairs and maintenance (avg.) | $1,400 | $11.67 | $5.00 |
| Film, twine, fuel (consumables) | variable | $13.00 | $13.00 |
| Owner-operator labour ($40/hr) | variable | $4.00 | $4.00 |
| TOTAL COST PER WRAPPED BALE | — | $64.00 | $37.14 |
⚡ The Key Insight From This Example
At 120 bales per year, the true cost per bale of $64 significantly exceeds typical contractor rates of $30–45 per wrapped bale — meaning contracting is likely more economical at this volume. At 280 bales per year, the $37 per bale cost is competitive with contractor rates — the economics begin to favour ownership. The volume at which ownership becomes more economical than contracting (the break-even point) varies by machine cost and local contractor rates but typically falls in the 200–250 bales per year range for mid-range machines in Australian conditions.
How to Reduce Your True Cost Per Bale
The Management Levers That Move the Number
Increase Annual Bale Volume
The single most powerful cost reduction lever is increasing the number of bales the machine produces per year. This spreads all fixed costs (depreciation, capital, insurance, registration) across more units. Options for increasing volume without expanding the farm’s own silage production include: custom baling for neighbours or contractors, renting the machine to other users, or concentrating silage production from multiple paddocks or blocks through the owned machine rather than splitting work with a contractor. Each additional 50 bales per year from the same machine typically reduces per-bale cost by $8–15 depending on where current volume sits on the fixed-cost curve.
Choose the Right Machine for Your Volume
A lower-purchase-price machine that is adequate for the farm’s volume produces lower per-bale cost than an over-specified machine producing the same annual bale numbers. A farm producing 150 bales per year does not need the same machine as one producing 400 — and buying the larger machine for its superior specifications without the volume to justify the higher capital cost produces a higher per-bale cost, not a lower one. Matching machine specification to actual production volume is the purchase decision that most directly affects long-run per-bale economics. For silage baler for sale matched to your volume, the Charlton team provides specific advice.
Extend Machine Service Life
A machine kept for 12 years instead of 8 years spreads the same purchase cost across 50% more total service life. The depreciation per year decreases as service life extends — this directly reduces the annual fixed cost and therefore the per-bale cost. Good maintenance is the key enabler of extended service life: a well-maintained silage baler can reliably deliver 15+ years of productive service. The maintenance cost that enables 15-year service life is considerably less than the additional purchase cost of a replacement machine, making proper maintenance one of the highest-return economic decisions in baler ownership.
Optimise Film Use
Film is the largest variable cost component per bale, and it can be managed more precisely than most other consumable costs. Using the correct layer count for each specific storage requirement (6 layers for standard 12-month storage, 8 for drought reserve or high bird-pressure sites) rather than a single default setting prevents both under-wrapping (spoilage risk) and over-wrapping (unnecessary film cost). Maintaining correct 50–55% overlap and checking for film roll consistency from different batches also reduces the effective film cost per bale without compromising storage quality.

The Non-Financial Benefits That the Cost Calculation Doesn’t Capture
When Owning Is Worth More Than the Numbers Show
A pure cost-per-bale comparison between owning and contracting may show that contracting is cheaper at the current volume — but cost is not the only relevant factor in the decision. Owning a silage baler provides several benefits that have real economic value but don’t appear directly in the per-bale cost calculation. Harvest timing flexibility — the ability to bale on the optimal day without waiting for contractor availability — can protect quality worth $5–15 per bale in DM preservation and nutritional value. The ability to bale in short windows (stopping for milking, resuming, stopping again) without paying contractor mobilisation fees for each event is a practical advantage for dairy operations. The availability of the machine for emergency re-baling after a film breach or for late cuts that a contractor may not prioritise also has real value. These benefits should be weighed alongside the per-bale cost comparison, not ignored in the pursuit of a simple numerical answer.
Ever-Power: Purchase Price That Improves Your Per-Bale Economics
Competitive Capital Cost With No Compromise on Silage Quality
Because purchase price drives the two largest fixed-cost components — depreciation and capital cost — the purchase price of the machine is the most directly controllable input to the per-bale cost equation. Ever-power’s silage baler range is priced competitively for Australian farm-scale operations precisely because the per-bale economics matter to the operations that buy these machines. A lower purchase price at equivalent specification quality reduces the depreciation component by a direct dollar-for-dollar amount: a machine costing $10,000 less produces $10,000 ÷ service life fewer depreciation dollars per year — a meaningful cost reduction that compounds across every bale produced over the machine’s service life.
