Do You Know Which Jobs Lose Money? 35% of Contractors Don't Track Job Profitability
Mark Anderson's agricultural contracting business generates £280,000 in annual revenue. After expenses, he nets about £42,000—a 15% profit margin. Not terrible, but not great either. He wondered why his profitability wasn't better given the volume of work.
When Mark finally started tracking profitability at the job level—not just overall business profit—he discovered something shocking:
Profitable Jobs (68% of his work):
- Average profit margin: 28-35%
- These jobs were highly profitable and worth his time
Break-Even Jobs (14% of his work):
- Profit margin: 0-8%
- Barely worth doing, tying up equipment for minimal return
Money-Losing Jobs (18% of his work):
- Profit margin: -5% to -12%
- Actually losing money on nearly 1 in 5 jobs
Mark was astonished. Almost 20% of his work was unprofitable, dragging down his overall business performance. The problem? He'd been pricing based on market rates and gut feel, not actual costs.
Why the unprofitable jobs existed:
- Distant client location (excessive travel time and fuel)
- Small acreage with high setup time
- Difficult field conditions (slow work, high equipment wear)
- Low pricing to win competitive bids
- Inefficient equipment for that job type
Mark's overall 15% profit margin was actually 68% of jobs at 30% margin dragged down by 32% of jobs at 0-10% margin or worse.
What changed when Mark started tracking job profitability:
- Declined or repriced the worst unprofitable jobs
- Focused capacity on high-profit work
- Adjusted pricing based on true costs
- Made equipment decisions based on profitability data
Results Year 1:
- Declined £48,000 in low/no-profit work
- Replaced with £52,000 in profitable work
- Overall profit margin: 15% → 24%
- Net profit: £42,000 → £67,200
- Income increase: £25,200 (60%) without working more
Mark's story is common. Industry surveys suggest 35-40% of agricultural contractors don't track profitability by individual job—they only know overall business profitability. The result: Unknowingly accepting unprofitable work that drags down margins.
Here's how job-level profitability tracking transforms agricultural contracting and farming operations.
The Profitability Blindness Problem
Most operations track:
- Total annual revenue
- Total annual expenses
- Overall profit
But they don't know:
- Which specific jobs are profitable
- Which clients are worth keeping
- Which services make money vs. lose money
- True cost per job type
What You Think vs. What's Real
Typical Contractor Perception:
- "All our work is profitable at market rates"
- "We charge £22/acre for spraying, that must be profitable"
- "Big jobs are always good"
- "We make money on everything"
Reality With Job Costing:
- Some jobs highly profitable (30-40% margins)
- Some barely break even (5-10% margins)
- Some actually lose money (-5% to -15% margins)
- Small highly profitable job often better than large low-margin job
Example Discovery:
Spraying Job A: 180 acres, £22/acre = £3,960 revenue
- Costs: £2,120 (fuel, labor, equipment, travel)
- Profit: £1,840 (46% margin) ✓ Excellent
Spraying Job B: 180 acres, £22/acre = £3,960 revenue
- Costs: £4,180 (distant location, difficult access, equipment issues)
- Profit: -£220 (LOSS!) ✗ Terrible
Same service, same acreage, same price—dramatically different profitability.
Without job costing: Both jobs look the same.
With job costing: One is great, one loses money.
Why Profitability Varies
Distance from Base:
- Travel time costs money (labor, fuel)
- More travel = lower profitability
- Example: Job 15 minutes away vs. 60 minutes away—dramatically different cost structures
Field Conditions:
- Easy, flat, rectangular field: Fast, efficient, profitable
- Hilly, irregularly shaped, rocky field: Slow, difficult, lower profit
- Same per-acre price, very different profitability
Equipment Efficiency:
- Right equipment: Efficient, profitable
- Wrong equipment: Slow, high cost, low profit
- Example: Small planter on large field = unprofitable
Setup/Breakdown Time:
- Large field: Setup time amortized over many acres
- Small field: Setup time eats entire profit
- 5-acre job can cost more per acre than 150-acre job
Client Behavior:
- Good clients: Pay on time, clear communication, easy to work with
- Difficult clients: Constant changes, payment delays, extra time required
- Difficult clients cost more to serve
Job Costing: Understanding True Profitability
Job costing means tracking all costs associated with specific jobs, then calculating profit per job:
Revenue Per Job
What's Invoiced:
- Acreage × rate
- OR hours × rate
- Materials markup
- Total revenue for that specific job
Costs Per Job
Direct Labor:
- Operator hours × wage rate
- Benefits/overhead allocation
- Travel time labor cost
Equipment Costs:
- Fuel consumed
- Equipment hours × cost per hour (maintenance, depreciation)
- Wear and tear
Materials:
- Seed, fertilizer, chemicals used
- Cost of goods sold
Travel:
- Fuel to/from job site
- Travel time (non-billable labor hours)
Overhead Allocation:
- Shop rent, insurance, office costs
- Allocated per hour or as percentage
Profit Calculation
Revenue - All Costs = Profit
Profit ÷ Revenue = Profit Margin %
Example Job Costing:
Fertilizer Spreading - Morrison Farm, North Field
Revenue: 140 acres × £15/acre = £2,100
Costs:
- Labor: 6 hours × £16/hour = £96
- Equipment: 6 hours × £24/hour = £144
- Fuel: 80 litres × £1.30/litre = £104
- Fertilizer: 35 tonnes × £42/tonne = £1,470
- Travel: 45 min × £16/hour + 18 litres fuel = £35
Total Costs: £1,849
Profit: £2,100 - £1,849 = £251
Profit Margin: £251 ÷ £2,100 = 12%
Verdict: Profitable, but lower than target 20% margin.
Action: Consider £16-17/acre pricing for similar jobs.
What Job Costing Reveals
When contractors implement job costing, common discoveries:
Discovery 1: Geographic Profitability Patterns
Revelation: Jobs within 15 miles highly profitable. Jobs 30+ miles away often unprofitable.
Why: Travel time and fuel costs eat profit on distant jobs.
Action: Focus on nearby clients, charge premium for distant work, or decline distant low-margin jobs.
Discovery 2: Client Profitability Varies Wildly
Revelation:
- Client A: Average 32% profit margin across all jobs
- Client B: Average 8% profit margin
- Client C: -3% average (losing money!)
Why: Some clients have easy fields, pay well, communicate clearly. Others have difficult conditions, negotiate prices down, require extra time.
Action: Focus on best clients, reprice or decline worst clients.
Discovery 3: Service Type Profitability Differences
Example Discovery:
- Spraying: 28% average margin (good)
- Fertilizer spreading: 18% average margin (acceptable)
- Planting: 35% average margin (excellent!)
- Custom harvesting: 12% average margin (low)
Action: Emphasis on high-margin services (planting), improve pricing or efficiency on low-margin services (harvesting).
Discovery 4: Equipment Utilization and Profitability
Revelation: New expensive combine generates 22% margin. Older reliable combine generates 31% margin (lower costs).
Why: Newer equipment has higher hourly costs (depreciation, financing). Must price accordingly or equipment becomes profit drag.
Action: Ensure pricing reflects true equipment costs.
Discovery 5: Small vs. Large Jobs
Common Assumption: Larger jobs always better.
Reality:
- Large easy job: 25% margin
- Small easy job: 32% margin (less travel, higher per-acre price)
- Large difficult job: 8% margin (low price to win competitive bid)
Truth: Profitability depends on pricing and conditions, not size alone.

Total: £320,000 revenue, £68,864 potential profit
Actual profit: £44,800
Difference: £24,064 lost to inefficiency and poor pricing
Analysis Revealed:
- 3 clients consistently unprofitable (difficult fields, low negotiated prices)
- Jobs over 25 miles away averaged 6% margin vs. 28% for nearby jobs
- Small acreage jobs (<20 acres) with high setup time unprofitable
Actions Taken:
- Repriced distant work (+15% travel surcharge)
- Declined 2 consistently unprofitable clients
- Increased minimum charges for small jobs
- Focused marketing on profitable service areas
Results Year 2:
- Revenue: £295,000 (reduced, but intentionally)
- Profit: £68,300 (23% margin)
- Profit increase: £23,500 (52%) despite £25,000 less revenue
- Worked less, earned more
Owner Quote: "Job costing was eye-opening. I was working hard, running equipment everywhere, and making very little on 20% of my jobs. Once I saw which work was profitable and which wasn't, the decision was easy: Stop doing unprofitable work. My revenue dropped slightly, but my profit jumped 50%. I work less hours now and make more money."
Case Study 2: Midwestern Farm - Enterprise Profitability
Operation: Henderson Farms, Iowa - 3,200 acres
Enterprises: Corn, soybeans, custom work for neighbors
Assumption: Farming own land most profitable, custom work side income.
Job Costing Revelation:
Own Farm Corn: £52/acre profit
Own Farm Soybeans: £38/acre profit
Custom Harvesting: £65/hour profit = £85/acre (13 acres/hour avg)
Custom Planting: £48/acre profit
Discovery: Custom work for neighbors MORE profitable per hour than farming own marginal ground.
Action:
- Rented out 400 acres of marginal farmland (£80/acre rent = £32,000)
- Used freed capacity for more profitable custom work
- Grew custom harvest operation (more profitable than farming)
Results:
- Overall farm profit: +18%
- Less land farmed, same/more profit
- Better equipment utilization
Quote: "We assumed farming our own ground was always the priority, and custom work was just side income during spare time. Job costing showed custom work was actually more profitable per hour than farming our worst 400 acres. Renting that ground out and doing more custom work increased our profit significantly."
Case Study 3: UK Agricultural Contractor - Service Profitability
Operation: Wilson Contracting
Services: Planting, spraying, spreading, tillage, harvesting
Assumption: All services similarly profitable at market rates.
Job Costing Analysis:
Planting: 31% average margin ✓ Excellent
Spraying: 24% average margin ✓ Good
Spreading: 19% average margin ✓ Acceptable
Tillage: 16% average margin ⚠️ Low
Harvesting: 9% average margin ⚠️ Very Low
Investigation:
- Planting: Modern efficient equipment, good pricing
- Spraying: Efficient, high margins per hour
- Spreading: Decent margins, good volume
- Tillage: Old equipment, slow, high fuel costs
- Harvesting: Competitive market, price pressure, equipment expensive
Actions:
- Expanded planting (most profitable)
- Maintained spraying and spreading (good margins)
- Upgraded tillage equipment (improved efficiency and margins to 22%)
- Exited harvesting (too competitive, low margins, tied up expensive equipment)
Results:
- Focused on highest-margin work
- Overall business margin: 18% → 26%
- Revenue stable, profit up 44%
Quote: "Before job costing, I thought all agricultural services earned similar margins. The data showed huge variation—planting at 31% and harvesting at 9%. Why tie up expensive equipment for 9% when I can do planting at 31%? We shifted focus to our most profitable services and our business transformed."
Implementing Job Costing
Step 1: Track Costs Per Job
What to Capture:
- Labor hours (operator time on specific job)
- Equipment hours (which equipment, how long)
- Fuel consumption (estimate or actual per job)
- Materials used (seed, fertilizer, chemicals)
- Travel time and distance
How to Capture:
- Digital systems: Automatic time tracking, equipment logging
- Manual: Job sheets with start/stop times, equipment used, materials
- Estimates: Use average costs if tracking perfectly is difficult
Step 2: Calculate Equipment Cost Per Hour
Need to Know: What does it cost to run each piece of equipment per hour?
Factors:
- Fuel consumption (litres/hour × fuel cost)
- Maintenance (annual maintenance ÷ annual hours)
- Repairs (annual repairs ÷ annual hours)
- Depreciation (optional but recommended)
- Insurance (annual insurance ÷ annual hours)
Example Tractor Cost Per Hour:
Fuel: 12 litres/hour × £1.30 = £15.60
Maintenance: £2,400/year ÷ 600 hours = £4.00
Repairs: £1,800/year ÷ 600 hours = £3.00
Depreciation: £6,000/year ÷ 600 hours = £10.00
Insurance: £1,200/year ÷ 600 hours = £2.00
Total: £34.60/hour
Do This Once: Calculate cost per hour for major equipment, use for job costing.
Step 3: Allocate Overhead
Overhead Costs (shop rent, insurance, office, etc.):
- Simple Method: Percentage of revenue (e.g., 12% of job revenue)
- Accurate Method: Cost per hour (annual overhead ÷ total billable hours)
Example: £24,000 annual overhead ÷ 2,000 billable hours = £12/hour overhead allocation
Step 4: Calculate Job Profit
For Each Job:
Revenue: What you invoiced
- Labor costs
- Equipment costs
- Materials
- Travel
- Overhead allocation
= Profit
Profit ÷ Revenue = Margin %
Step 5: Analyze and Act
Monthly Review:
- Which jobs most/least profitable?
- Patterns by client, service type, geography?
- Pricing adjustments needed?
Quarterly Decision-Making:
- Focus on high-profit work
- Reprice or decline low-profit work
- Equipment and capacity decisions
- Marketing and growth strategy

Conclusion: Know Your True Profitability
35-40% of contractors don't track job-level profitability—they only know overall business profit. The result: Unknowingly accepting unprofitable work that drags down margins.
Job costing reveals:
✅ Which jobs make money (focus here)
✅ Which jobs lose money (decline or reprice)
✅ True cost by service type
✅ Client profitability patterns
✅ Geographic profitability
✅ Equipment efficiency and ROI
Without job costing: Work hard, wonder why margins aren't better
With job costing: Work smart, focus on profitable work, increase margins 15-30%
Stop guessing profitability. Start knowing it.
Frequently Asked Questions
Is job costing worth it for small operations?
Yes. Even small operations benefit from knowing which work is profitable. If you do 50-100 jobs annually, knowing which 20% are most profitable guides where to focus. The principle scales—small operations just have fewer data points but same insight value.
How accurate does cost tracking need to be?
Reasonable accuracy is sufficient. You need to know if a job makes 25% vs. 10% vs. loses 5%—not whether it's 24.3% vs. 24.7%. Use average equipment costs, reasonable labor rates, estimated fuel. 80% accuracy reveals patterns and guides decisions.
What if costs vary seasonally?
Track that variation. Fuel costs higher in winter? Labor costs vary with overtime? Capture that in your cost tracking. Many systems allow seasonal cost adjustments. Or use annual averages for simplicity (still reveals profit patterns).
Should we include depreciation and overhead?
For complete picture, yes. But even tracking just direct costs (labor, fuel, materials) reveals profit patterns. Start simple (direct costs), add sophistication (depreciation, overhead) over time. Something is better than nothing.
What about jobs we do for goodwill or relationships?
Some contractors do occasional low-profit work for strategic reasons (key client relationship, community goodwill, fill equipment idle time). That's fine—but do it KNOWINGLY based on data, not unknowingly because you don't track profitability. Conscious strategic decisions different from accidental money-losing work.
How do we handle time-and-materials jobs?
Job costing still works. Track costs as usual, compare to what you invoiced. Reveals whether your T&M rates are appropriate. Many contractors discover their hourly rates don't fully cover costs when they actually calculate true cost per hour.
