Drive Time, Mileage, and Margin: How to Charge for the Windshield Time

# Drive Time, Mileage, and Margin: How to Charge for the Windshield Time

Every drone job has a hidden cost the client never sees: the drive. You can bill it as flat-rate travel, hourly drive labor, or eat it and lean on the mileage deduction at tax time. Each path lands somewhere different on your bottom line — and chaining missions together, or driving too far can flip a "no" to a "yes," or a "yes" into a "walk away" fast.

The three ways to charge for the windshield time

1. Flat-rate travel fee

You quote one number (say, $75) regardless of how the day actually plays out.

• Pro: Clean for the client, no surprise add-ons.
• Con: If traffic, a closed road, or a re-route adds 40 minutes, that time is on you.
• Margin effect: Predictable on paper, volatile in reality. Works best when you know the route cold.

2. Hourly drive labor

Bill drive at your shop rate (or a discounted "travel rate"), plus IRS-rate mileage for the vehicle.

• Pro: You get paid for every minute behind the wheel. Long drives stop being charity.
• Con: Sticker shock. A 90-minute round trip at $75/hr is $112 before you've unpacked the drone.
• Margin effect: Highest realized margin per job, lowest close rate on price-sensitive leads.

3. No travel charge — take the mileage deduction

You absorb drive time and write off the miles (2026 IRS business rate) against income.

• Pro: Most competitive quote on paper. Easiest sale.
• Con: The deduction only refunds your tax on those miles — roughly 22–32¢ back per mile depending on your bracket, not the full 72.5¢. You're still down the unbilled hour.
• Margin effect: Looks fine on the invoice, quietly bleeds margin on anything over ~20 miles one-way.

Quick margin comparison

Same job: $450 quote, 60-mile round trip, 90 minutes of total drive time, 1 hour on-site.

The "free travel" version isn't free — it's a 25% pay cut.

Linking missions changes the math

Chaining two or three missions in the same trip is the single biggest lever you have. The drive cost gets amortized across multiple invoices instead of eaten by one.

• A solo 60-mile round trip on a $450 job sits at ~$143/hr if you don't charge travel.
• Add a second $300 mission five miles away, and that same drive is now spread over $750 of revenue. Effective rate jumps back above $200/hr without changing either client's quote.
• If you're charging flat-rate travel, don't bill the second client the same fee — split it, discount it, or skip it. Double-charging the same windshield time kills repeat business.

Rotor Rate's chain builder is designed for exactly this: it lets you see the combined margin across linked missions and flags when the second job is only profitable because it's piggybacking the first.

When to walk away

Drive distance is also a verdict tool. A useful rule of thumb based on round-trip windshield time vs. on-site billable time:

• < 1:1 (drive ≤ on-site) → Take it. Margin is healthy.
• 1:1 to 2:1 → Thin margin. Only take it if you can charge travel, chain another mission, or it's a strategic client.
• > 2:1 → Walk away, or quote it so high that you're indifferent. You're selling drive time, not drone work, and the deduction won't save it.

A 2-hour round trip for a 45-minute roof inspection at "standard pricing" is almost always a loss once you count loading, unloading, post-processing, and the opportunity cost of the half-day it consumed.

The takeaway

• Flat-rate travel is the right default for most local work.
• Hourly drive is the right answer for anything over an hour one-way, or for clients who already understand professional service billing.
• The mileage deduction is a tax tool, not a pricing strategy. Treating it like revenue is how solo operators end up working 50-hour weeks for 30 hours of pay.
• Chain missions whenever geography allows — it's the cleanest way to rescue a marginal drive.
• Use the 2:1 rule before you accept a far-away job. Your calendar is the most expensive thing you own.

Price the windshield time like you price the flight. Otherwise the road is quietly eating your margin one job at a time.
