Break-Even Analysis: How Many Details Until You're Profitable
The number that tells you if your business model actually works.
Your break-even point is the number of jobs you need to cover all your costs — after that, every job is profit. If the break-even number is unrealistic for your schedule, either your prices are too low or your costs are too high.

What Is Break-Even?
Break-even is the point where your revenue exactly equals your costs. Below break-even, you're losing money. Above it, you're making profit.
For a detailing business, this translates to: How many jobs per month do I need to cover all my expenses?
This isn't just a theoretical exercise. Your break-even number tells you:
- If your business model is viable
- How many days per week you actually need to work
- Whether your pricing makes sense
- What happens if you raise or lower prices
- Whether you can afford that new equipment or truck payment
If your break-even requires 30 jobs per month but you can realistically only do 20, your business is structurally unprofitable. That's not a motivation problem — it's a math problem.
The Break-Even Formula
The basic break-even formula is:
Break-Even (jobs) = Fixed Costs ÷ Average Job Contribution
Where:
- Fixed Costs = Your monthly overhead that doesn't change based on job volume (truck payment, insurance, subscriptions, etc.)
- Average Job Contribution = Average revenue per job minus variable costs per job
Let's break this down with real numbers.
Step 1: Calculate Your Fixed Costs
Fixed costs are expenses you pay whether you do 5 jobs or 50 jobs this month. For a typical mobile detailer:
Monthly Fixed Costs
Vehicle payment.........................$580
Commercial auto insurance................$195
General liability insurance..............$110
Phone (business portion).................$65
Software subscriptions...................$85
Equipment financing (if any).............$200
Marketing budget (average)...............$150
Miscellaneous/buffer....................$115
Total Fixed Costs......................$1,500
Your numbers will differ. Maybe you own your truck outright ($0 payment), or you have a shop ($800/month rent). Calculate YOUR fixed costs.
Step 2: Calculate Average Job Contribution
"Contribution" means how much each job contributes toward covering your fixed costs and ultimately profit.
Average Job Contribution = Average Job Revenue - Variable Costs per Job
Variable costs are expenses that scale with each job:
- Chemicals and products used (~$15-30 per job average)
- Consumables (towels/pads wear, ~$5-10 per job)
- Fuel for that job (~$10-20 depending on distance)
Example:
Average job revenue......................$350
Variable costs per job:
- Chemicals/products...................$22
- Consumables..........................$8
- Fuel.................................$15
Total variable costs.....................$45
Average Job Contribution: $350 - $45 = $305
Step 3: Calculate Break-Even
Now we can calculate:
Break-Even = $1,500 ÷ $305 = 4.9 jobs
This detailer needs to complete 5 jobs per month just to cover their fixed costs. Every job after that is profit.
Is 5 jobs per month realistic? Absolutely. Most full-time detailers can do 5 jobs per week. This business model has healthy margin.
What If the Number Scares You?
Let's look at a less healthy scenario:
Higher Overhead Detailer
Monthly fixed costs:
- Sprinter payment.....................$850
- Equipment financing..................$400
- Insurance............................$380
- Phone/software.......................$150
- Marketing............................$300
- Storage unit.........................$175
Total Fixed Costs......................$2,255
Average job revenue......................$275 (lower pricing)
Variable costs per job...................$50
Average Job Contribution................$225
Break-Even: $2,255 ÷ $225 = 10 jobs per month
10 jobs per month sounds manageable. But let's add one more factor: the owner needs to pay themselves.
If this detailer wants to take home $4,000/month after taxes (about $5,700 before taxes to account for SE tax), we need to add that to fixed costs:
Fixed costs.............................$2,255
+ Owner's minimum draw..................$5,700
Total needed monthly....................$7,955
Break-Even: $7,955 ÷ $225 = 35.4 jobs per month
Now they need 36 jobs per month to meet their financial needs. That's about 9 jobs per week, every week. If each job averages 3 hours plus 30 minutes travel, that's roughly 32 hours of work per week — doable, but leaving little room for admin, marketing, or slow weeks.
This business model works, but it's tight. Any increase in costs or decrease in jobs creates stress.
The Three Levers of Break-Even
If your break-even number is uncomfortably high, you have three levers to pull:
Lever 1: Raise Prices
Increasing your average job from $275 to $375 changes everything:
New contribution: $375 - $50 = $325
Break-Even: $7,955 ÷ $325 = 24.5 jobs (vs. 35.4)
A $100 price increase reduced the required jobs by 30%. That's the power of pricing.
Lever 2: Lower Fixed Costs
Can you get a cheaper vehicle? Reduce equipment payments? Cut unnecessary subscriptions? Every dollar of fixed cost reduction directly reduces your break-even.
If fixed costs drop from $2,255 to $1,500:
Break-Even: ($1,500 + $5,700) ÷ $225 = 32 jobs (vs. 35.4)
Lever 3: Lower Variable Costs
Buy chemicals in bulk. Optimize routes to reduce fuel. Get more uses out of towels and pads. Every dollar saved per job increases contribution.
If variable costs drop from $50 to $35 per job:
New contribution: $275 - $35 = $240
Break-Even: $7,955 ÷ $240 = 33.1 jobs (vs. 35.4)
Pricing has the biggest impact. A 10% price increase often reduces break-even by 15-20%. Most detailers undercharge; raising prices is usually the fastest path to a healthier business.
Using Break-Even for Decision Making
Break-even isn't just for startup planning. Use it for ongoing decisions:
Should I buy that equipment?
A $3,000 polishing system financed at $150/month adds to fixed costs. Does the equipment let you raise prices enough to offset it? If the polisher enables $50 higher prices on correction work and you do 5 corrections per month, that's $250/month — well above the $150 payment. It makes sense.
Should I upgrade my truck?
Going from a $400 payment to $800 adds $400 to fixed costs. At $300 contribution per job, that's roughly 1.3 more jobs per month just to stay even. Can you reliably book an extra 1-2 jobs monthly? If yes, maybe. If you're already at capacity, probably not.
Can I afford to hire?
An employee costs $3,500/month (wages + taxes + insurance). At $200 contribution per job (lower for employee work due to lower efficiency initially), that's 17.5 additional jobs per month just to cover their cost. Can your market support that volume? Can you sell that many additional jobs?
Break-Even and Seasonality
Detailing is seasonal for most markets. Your break-even doesn't change based on season, but your ability to hit it does.
Strategy: Calculate your annual break-even, not just monthly.
Annual fixed costs: $1,500 × 12 = $18,000
Annual owner's draw: $5,700 × 12 = $68,400
Total annual need: $86,400
At $305 contribution per job:
Annual Break-Even: 283 jobs
That's about 24 jobs per month average — or:
- 30 jobs/month during peak season (7 months)
- 15 jobs/month during slow season (5 months)
Total: 210 + 75 = 285 jobs
Build up reserves during peak season to cover slow months. If you earn above break-even in March-October, you can survive below break-even in November-February.
Your Break-Even Worksheet
Common Mistakes
→ Add your minimum required take-home (plus taxes) to fixed costs. Break-even without owner pay is meaningless — you need to earn a living.
→ Each job doesn't contribute its full price toward fixed costs — you have variable costs per job. Always subtract variable costs to get true contribution.
→ New truck? New equipment? Changed pricing? Recalculate your break-even. It's not a one-time exercise.
→ Break-even is a target, not a guarantee. You still need to book the jobs. Marketing, quality, and seasonality affect whether you actually reach it.
→ If break-even requires 50 jobs/month but you can physically only do 35, your business model is broken. Either raise prices dramatically or cut costs.
Calculate your break-even right now using the worksheet above. Be honest about your costs and realistic about your average job. If the number is higher than you can reliably hit, you've identified a problem. Now solve it — raise prices, cut costs, or both.
Track every job in Detaild to know your true average job value. Over time, you'll see exactly what your contribution margin is — and whether it's trending up or down.
Calculate two break-even numbers: 'survival' (covers fixed costs only) and 'thriving' (covers fixed costs plus your target income). Know both. Survival mode should feel easy to hit; thriving mode is your real target.
Frequently Asked Questions
What's a healthy break-even for a mobile detailer?
Most healthy mobile detailing operations break even at 8-15 jobs per month (without owner pay) or 20-30 jobs per month (including target owner income). If you need 40+ jobs monthly just to break even, either your prices are too low or your overhead is too high.
Should I include my personal expenses in break-even?
Include what you need to pay yourself from the business to cover personal expenses. If you need $5,000/month take-home to pay rent, food, etc., that's roughly $7,000 pre-tax from the business. Add that to fixed costs.
How does break-even change if I add employees?
Employee costs become fixed costs (or semi-fixed). Their wages add to what you need to cover, but ideally they generate enough additional revenue (and contribution) to more than cover their cost. Run the math before hiring.
What if my job prices vary a lot?
Use a weighted average based on your actual job mix. If you do 50% maintenance washes ($175) and 50% full details ($350), your average is $262.50. Use that for break-even calculation.
How often should I recalculate break-even?
At minimum, annually. Also recalculate when: you change pricing, add significant fixed costs (new vehicle, equipment), or change your service mix materially. It takes 5 minutes and keeps you grounded in reality.
