Should I Charge for Mileage? The Break-Even Math
Should I charge for mileage? Here is the break-even math home inspectors use to set a free travel radius, price distance zones, and quote it without losing jobs.
Yes, you should charge for mileage once a job pushes past the travel distance your standard fee already assumes. The harder question is where that line sits, and the answer is arithmetic, not opinion: add your true cost per mile to the value of your windshield time, compare it to the margin on the inspection, and the break-even distance falls out on its own.
Most inspectors get this wrong in one of two directions. They either absorb every drive because they are afraid of losing the booking, or they slap on a mileage rate copied from the IRS and quietly lose money anyway. Below is how to run the numbers with your own figures, turn them into a clean zone ladder, and quote it in a way that rarely costs you the job.
The two costs you are actually covering
A travel fee is not one cost. It is two, and they are wildly different in size.
Vehicle cost. Fuel, tires, brakes, oil, insurance, registration, and the depreciation you are spending whether you notice it or not. This is what the IRS standard business mileage rate is designed to approximate. That rate is published annually and is a reasonable stand-in if you have never tracked your own numbers.
Your time. An hour in the truck is an hour you cannot inspect, write, sell, or go home. This is the expensive half, and it is the half the IRS rate does not touch. The single most common pricing mistake in this whole conversation is treating the IRS rate as a travel fee. It reimburses the vehicle, not the driver.
Once you separate those two, the math gets easy.
Step 1: Find your true cost per mile
Pull twelve months of vehicle expenses and divide by twelve months of business miles. Include fuel, maintenance, tires, insurance, registration, and either your lease payment or a realistic depreciation figure for a truck that lives on job sites.
If you have no records, use the current IRS standard mileage rate as a placeholder and fix it later. For the worked examples in this article, assume an illustrative $0.70 per mile. Substitute your own.
Step 2: Put a number on your hour
Take your target annual owner compensation plus overhead, and divide by the hours you can realistically sell. Many solo inspectors land somewhere between $75 and $150 per productive hour once they do this honestly. Use whatever number your own math produces.
For the examples below, assume an illustrative $100 per hour and an average travel speed of 45 mph, which is a fair blend of surface streets and highway in most metros.
Step 3: Calculate the cost of one mile of radius
Every mile of distance from your base is two miles of driving. So:
- Vehicle: 2 miles x $0.70 = $1.40
- Time: 2 miles / 45 mph = 0.044 hours x $100 = $4.44
- Total: about $5.84 per mile of one-way distance
That is roughly $2.90 per round-trip mile, which is four times the illustrative vehicle-only rate. This is the number that should shape your policy.
Run it out and the picture sharpens:
| One-way distance | Round-trip miles | Vehicle cost | Windshield time | Total true cost |
|---|---|---|---|---|
| 10 mi | 20 | $14 | 0.44 hr | ~$58 |
| 20 mi | 40 | $28 | 0.89 hr | ~$117 |
| 35 mi | 70 | $49 | 1.56 hr | ~$205 |
| 50 mi | 100 | $70 | 2.22 hr | ~$292 |
| 75 mi | 150 | $105 | 3.33 hr | ~$438 |
A 75-mile job can cost as much as an entire inspection fee before you open the electrical panel. That is why "I'll just eat the drive" is not a strategy.
Step 4: Find your actual break-even distance
Here is the part most articles skip. Your current price is not a blank slate. It already has some amount of travel baked into it, because you built it around the jobs you normally do.
So your break-even is not zero miles. It is the average travel distance already funded by your standard fee.
To find it, pull your last 40 to 60 inspections and calculate the average one-way distance from your base. If that average is 18 miles, your pricing has been absorbing roughly $105 of travel cost per job all along and you have been fine. That is your free radius, or very close to it.
From there, the rule is simple:
> Free radius = your historical average travel distance. Everything beyond it is marginal cost that nothing in your price is paying for.
Round it to something clean and memorable. If the math says 18 miles, publish 20. If it says 31, publish 30. Customers remember round numbers, and the couple of dollars you give up buys a policy people can repeat.
Step 5: Build the zone ladder
Now convert the marginal cost into a published ladder. You will usually recover somewhere between half and all of the true cost, depending on how competitive your market is and how much you value filling the calendar.
Using the illustrative numbers above with a 20-mile free radius:
| Zone | One-way distance | True marginal cost | Published travel fee |
|---|---|---|---|
| 1 | 0 to 20 mi | included | $0 |
| 2 | 21 to 35 mi | ~$88 | $50 |
| 3 | 36 to 50 mi | ~$175 | $95 |
| 4 | 51 to 75 mi | ~$320 | $175 |
| 5 | 75+ mi | varies | custom quote, prepaid |
Three or four zones is the sweet spot. Two feels arbitrary at the edges, six is a pricing sheet nobody reads.
Notice the published fees recover roughly 55 to 60 percent of true cost. That is a deliberate choice: the zone fee covers the hard costs and most of the time, while the remaining margin on the inspection itself covers the rest. If you are the only inspector serving a rural county, you can recover closer to 100 percent. If you are fighting for suburban tract homes, you may recover less and use distance as a soft filter instead.
Four ways to structure it
| Model | How it works | Best for | Watch out for |
|---|---|---|---|
| Free radius plus zones | No fee inside X miles, flat fee per zone beyond | Most metro and suburban inspectors | Zone boundaries invite haggling, so define them by driving distance, not straight-line miles |
| Per-mile beyond radius | $X per round-trip mile past the free zone | Inspectors with wide, irregular service areas | Set the rate from your real cost, not the IRS rate, and add a minimum |
| Flat statewide pricing | Travel averaged into every fee, no separate line | Rural markets where long drives are the norm | Nearby clients subsidize far ones, which can price you out of your own backyard |
| Distance-based minimum | No travel fee, but the job must clear a dollar floor | Inspectors who upsell ancillaries | Requires discipline to say no to small far-away jobs |
A hybrid works well: free radius plus zones for standard homes, and a hard minimum fee, say $600, for anything past 50 miles. Whichever number is higher wins.
How to quote it without losing the job
The fee is rarely the problem. The surprise is the problem.
- Publish it. Put the free radius and the zone fees on your pricing page and your booking form. A client who sees it before they call has already accepted it.
- Quote it as one number. "That one is $625 all in" lands better than "$450 plus a $175 travel fee." Itemize on the invoice if you like, but lead with the total.
- Name the reason once, plainly. "You're about an hour out, so there's a travel charge for that area." No apology, no long justification. Confidence does most of the work.
- Collect up front on long hauls. Anything past your second zone should be prepaid or deposit-secured. A cancellation 60 miles from your office is an entire morning gone.
- Offer the alternative, not the discount. If the fee is a real obstacle, offer a specific day you are already headed that direction rather than cutting the price.
The edge cases worth planning for
Re-inspections. A short punch-list re-check has almost no inspection time and almost all travel time. Price re-inspections by trip, not by scope, and apply the same zone ladder.
Routing and batching. Two inspections in the same far zone on the same day share one long drive. It is entirely fair to discount the second job's travel fee, and it is smart scheduling to encourage it with agents who work that area.
Agent relationships. A high-volume agent who sends you 30 files a year in a far suburb is a different economic case than a one-off buyer. Waiving travel for that agent is a marketing expense with a measurable return. Waiving it for everyone is just a price cut.
Deductions are not reimbursement. Yes, business mileage is deductible. A deduction reduces taxable income, it does not pay you back. Never let "I write it off" substitute for charging.
Track it, then revisit it
The fastest way to know whether your policy is working is to look at the data you already generate. If your practice management system records the property address and the fee on every job, you can review average travel distance by month, see which zones actually convert, and spot the quarter where fuel prices moved enough to justify a change.
Modern home inspection software helps here in unglamorous ways. A CRM that stores client, agent, and property history gives you the address list to run the average. A booking flow that captures the address before the price is confirmed lets you apply the right zone automatically instead of negotiating it later. Custom business reporting turns "I feel like I'm driving more" into a number you can act on.
Revisit the arithmetic twice a year, or any time fuel moves sharply or your service area shifts. The formula does not change. Only the inputs do.
