Tractor Operating Costs Calculator
Calculate the true cost of running your tractor per work hour or per hectare — covering depreciation, finance, fuel, labour, maintenance and tyres.
Purchase & Depreciation
Finance
Leave blank if no outstanding finance.
Annual interest on outstanding balance
Maintenance & Tyres
Estimate for unplanned breakdowns
Full set replacement cost
Labour & Fuel

Fill in the sections above to see your cost breakdown.
Estimate only. Actual costs vary with machine age, workload, field conditions and market prices. Labour should reflect the true cost of employment including NI and holiday pay. Review with your accountant for business planning.

Purchase price
£85,000–£120,000
Depreciation
£6,000–£9,000/yr
Service cost
£1,200–£2,000/yr
Fuel use
10–16 L/hr
Purchase price
£130,000–£185,000
Depreciation

Benchmark figures based on typical UK farm machinery costs. New purchase prices at 2026 levels. Fuel at 95p/litre red diesel. Labour at £16/hr. Annual hours 1,000–1,200 for larger tractors.
Fixed vs Variable Costs — Why It Matters for Machinery Decisions
Understanding the distinction between fixed and variable costs is fundamental to good machinery management decisions — particularly when deciding whether to own a tractor, replace it, or use a contractor.
Fixed Costs — unavoidable once you own the machine
- Depreciation — occurs whether the tractor is used or not
- Finance interest — paid on the outstanding loan balance
- Insurance and road tax — annual fixed charge
- A proportion of maintenance — scheduled services
Variable Costs — only incurred when the tractor is used
- Diesel — directly proportional to hours worked
- Labour — only paid when the tractor is operating
- Repair costs — broadly linked to usage intensity
- Tyres — wear related to distance and surface
The practical implication
When deciding whether to do an extra job: only the variable costs need to be covered to break even — fixed costs are already committed regardless. A tractor costing £40/hr total but only £18/hr variable will break even on any job above £18/hr if it would otherwise sit idle.
When deciding whether to own at all: both fixed and variable costs must be covered by productive hours. A tractor doing 400 hours per year has much higher fixed cost per hour than one doing 1,200 hours — the same machine, half the utilisation, twice the fixed cost per hour.
How to Use Your Tractor Cost Per Hour Figure
Setting a contractor rate
Your cost per hour is the minimum charge rate for any contracting work. Add a profit margin of 20–30% to arrive at your contract price. Check this against local contractor rates — if your cost exceeds the market rate, the work may not be viable.
Comparing own vs contractor
Compare your true cost per hour (from this calculator) against the contractor's all-in rate including driver. If the contractor charges £55/hr and your own cost is £45/hr, owning and operating saves £10/hr — but only if you have enough productive work to justify the fixed costs year-round.
Job costing
Multiply cost per hour by the time taken for a specific job to get the true machinery cost. Use the per-hectare figure directly for field operations. This lets you compare the true profitability of different enterprises and crops.
Replacement decision
When your cost per hour rises significantly due to repair costs and high maintenance, compare against the cost per hour of a replacement. A newer tractor with lower repair costs and better fuel economy may be cheaper to run than an old one with high unexpected repair bills.
Benchmarking
Compare your calculated cost per hour against the benchmark table above. If your cost is significantly higher, investigate which component is causing the difference — usually depreciation (paid too much), finance (high interest rate), or fuel consumption (older or inefficient engine).
