Enter your weekly job volume, average job value, materials cost, labor, fuel, and overhead — the calculator shows monthly gross and net profit for your towing operation.
Towing looks like a high-cash-flow business until you sit down with the numbers. A truck doing 22 jobs per week at $180 average is grossing $27,720 per month — before the fuel, truck payment and maintenance, insurance, dispatcher costs, and labor that towing operations carry. A rig consuming $2,400 in fuel, pulling a $1,800 truck payment, carrying $1,600 in commercial vehicle insurance, and paying a driver $4,200/month has $10,000 in recurring fixed costs before a single variable expense is counted.
This calculator runs the full stack. Enter Jobs Per Week and Working Weeks Per Month, set Average Job Value and Materials/Parts Cost percentage, then fill in Monthly Labor Cost, Monthly Vehicle/Fuel, Monthly Overhead, and Monthly Marketing. The result is gross revenue, cost breakdown, and net profit — the real picture your dispatch log never shows you.
Job volume and average job value: two levers that don't always move together
A motor club towing contract provides volume — the calls come in consistently — but at suppressed rates, often $35–$65 per job for a light tow. Private-pay roadside and accident calls pay $150–$400 per hook. The same 22 jobs per week at $55 average versus $175 average is the difference between $1,210 and $3,850 in weekly gross. The mix of your job sources defines your average job value more than anything else.
Enter your real average job value based on your actual job mix, not your best week or your highest-rate calls. If motor club volume makes up 60% of your jobs, your blended average will reflect that. The calculator will show you the monthly gross at that blended rate, and you can test scenarios — what if motor club drops to 40% and private pay grows to 60%? — by adjusting the average job value input.
Vehicle and fuel costs: the biggest variable most tow operators undercount
Monthly Vehicle/Fuel is the single largest operating cost in most towing operations and the one most prone to underestimation. A wrecker running 800–1,200 miles per week between jobs, hook-ups, and repositioning can consume $1,800–$3,500 in diesel per month depending on fuel prices and rig efficiency. Add the truck payment ($1,500–$2,500 for a commercial wrecker), maintenance reserve ($400–$800/month for a working unit), and commercial plate and registration, and you are looking at $4,000–$7,000/month in vehicle line items before you count the driver.
Enter your real monthly vehicle and fuel number — pull the last three months of actual expenses and average them, not a best-case estimate. Fuel prices and maintenance timing make this variable, and a bad month with a transmission service or tire replacement can spike the number by $2,000. Operators who model with realistic vehicle costs avoid the surprise of a month where they worked hard and kept nothing.
Materials and parts cost: varies by call type
The Materials/Parts Cost (%) field covers supplies and parts consumed per job: dolly equipment, chains and hooks wear costs, winch line replacement amortized, and any parts or fluids used on service calls. For a pure towing operation with no on-site repair, this percentage is low — often 3–7% of job revenue. For a towing and light service operation that does roadside battery jumps, lockouts, and tire changes, the percentage rises because service calls consume more consumables.
If your operation does accident recovery with specialized equipment, rollback and flatbed jobs requiring extra rigging, or heavy-duty commercial towing, the materials percentage reflects the cost of equipment wear at a higher rate. Enter the percentage that reflects your actual call mix, not a generic industry benchmark.
Dispatch, labor, and the owner-operator math
Monthly Labor Cost covers dispatchers and employed drivers. For an owner-operator running the truck personally, this line is effectively zero — but only if you are not counting the value of your own time. Leaving owner labor at $0 inflates net profit by exactly what your time is worth. A realistic owner wage for a working driver-owner is $4,000–$6,000/month when benchmarked against what an employed driver costs.
For a fleet with two trucks and two drivers plus a part-time dispatcher, labor is the largest single cost line — often $9,000–$14,000/month. The calculator lets you model both scenarios. Enter the actual payroll for employees, and for owner-operators, either include a fair wage for yourself or understand that the net profit includes your own labor compensation.
Marketing spend and motor club versus private-pay balance
Monthly Marketing in a towing operation covers the expenses of building private-pay volume: Google Local Services ads, Yelp advertising, wrapping the truck with the phone number, and dealership or body shop referral programs. Motor club relationships require no marketing spend but cap your per-job rate. Private pay calls require marketing investment but pay 3–5x more per job.
The breakeven question is: how many private-pay jobs per month does $800 in Google ads need to produce to justify the spend? If private-pay adds $120 to your average job value and your current blended average is $85, every additional private-pay job adds $120 net before subtracting the acquisition cost. At $800/month marketing, you need roughly 7 additional private-pay jobs to break even on the spend. Test that threshold in the calculator by adjusting average job value and reading the net difference.

Who it's for
- Owner-operator deciding whether to add a second truck — Current operation grosses $14,800/month at 18 jobs/week. Net is $3,900 after all costs including a fair owner wage. A second truck would add $5,200 in vehicle/fuel/insurance costs and need to generate 9+ additional jobs/week at current blended rate to be net-positive. The numbers are tight — validates waiting until private-pay volume grows first.
- Fleet owner evaluating motor club contract renewal — Motor club volume is 55% of jobs at $52 average. Private-pay is 45% at $195 average. Blended average is $116. Dropping motor club and backfilling with 60% more private-pay jobs (through marketing spend) would raise blended average to $195 on fewer jobs. The calculator shows the crossover point — and whether the marketing investment to get there is realistic.
- New entrant pricing their first service — Starts with 10 jobs per week at $140 average, $2,800 vehicle costs, $1,200 overhead, no employees. Net $1,620/month — enough to cover personal expenses while building volume. Sees that 16 jobs per week at current pricing puts net above $3,500 and justifies the operation full-time.
- Operator stress-testing a fuel price spike — Current model at $2.40/gallon diesel with $2,100/month in fuel. Modeling $3.20/gallon raises vehicle/fuel to $2,800. Net drops by $700/month. Either a $9 average job value increase or 3–4 more jobs per week is needed to absorb a diesel price spike at that magnitude.
Key terms
- Average job value
- Total monthly gross revenue divided by total jobs completed. The blended per-job revenue across all call types — motor club, private-pay, insurance, and cash.
- Motor club rate
- The per-job rate paid by roadside assistance programs like AAA or insurance motor clubs for dispatched towing services. Typically $35–$75 per light tow — lower than private-pay rates but providing consistent volume.
- Working weeks per month
- The average number of productive weeks in a month accounting for planned downtime, maintenance, and scheduling gaps. For most single-truck operations, this ranges from 3.5 to 4.3 weeks depending on maintenance frequency.
- Materials cost percentage
- Consumable supplies and equipment wear costs as a share of job revenue — chains, hooks, rigging equipment amortized, dollies, and any roadside service supplies used per call.
Frequently asked questions
How should I handle jobs that vary widely in value — light tows versus heavy recovery?
Use the blended average across all job types in a typical month. Pull your dispatch records for the last 60–90 days, divide total revenue by total job count. That is your real average. If heavy recovery represents 10% of jobs but 30% of revenue, the blended average captures that mix accurately.
What is a realistic net margin for a towing operation?
Owner-operator single-truck operations with good private-pay mix typically net 20–35% of gross revenue. Fleet operations with employed drivers typically net 10–20% due to higher labor cost. Motor club-heavy operations with low average job values can run 8–15% net if volume is sufficient to cover fixed truck costs.
Should commercial vehicle insurance be in overhead or vehicle/fuel?
Either works — just be consistent. Many tow operators lump insurance with vehicle/fuel because it is tied to the unit rather than general business operations. Others include it in overhead. The total cost is what matters for the net calculation, not which line item it sits in.
How do I account for downtime when a truck is in for repairs?
Reduce Working Weeks Per Month to reflect expected down time. If your truck historically goes down 1 week per quarter for maintenance and repairs, model 3.5 working weeks per month instead of 4.3. This gives a more conservative net projection that accounts for the reality of operating commercial vehicles.
