How to Bill for Travel Time: Rates, Rules and Wording

Quick answer: To bill for travel time, agree the method in writing before the job, then invoice it as a separate line. Common methods are hourly travel at full or half rate, portal-to-portal time (from leaving your base to returning), a flat trip or zone fee, and mileage for vehicle costs. Show the dates, hours or miles and the rate, such as "Travel time: 2.5 hrs at $45/hr (50% rate)."

Travel is time you cannot spend on paid work, plus real vehicle and transport costs. Whether you are a plumber driving across town, a consultant flying to a client or a photographer heading to a venue, you need a consistent, fair way to bill for it. This guide compares the methods, explains how to choose rates, shows how to combine time and mileage, gives contract and invoice wording, and walks through worked examples.

What does billing for travel time mean?

Billing for travel time means charging a client for the hours you spend traveling to, from or between their work locations, either at your normal rate, a reduced rate or as a flat fee. It is distinct from:

• Mileage: a per-mile charge for vehicle running costs. See our mileage invoice guide.
• Travel expenses: flights, hotels, parking, tolls and meals, usually billed at cost as reimbursable expenses.
• Service call fee: a flat trip charge for coming out to a site.

Many businesses use a combination: for example, a trip charge for local visits and hourly travel plus expenses for out-of-town work.

Methods for billing travel time compared

Method	How it works	Common in	Pros	Cons
Full hourly rate	Travel billed like work hours	Consultants, lawyers, IT on-site support	Simple; fully compensates time	Clients may push back
Reduced rate (e.g. 50%)	Travel billed at a fraction of normal rate	Professional services, freelancers	Seen as fair	Undercompensates if travel blocks other work
Portal-to-portal	Clock runs from leaving base to returning	Towing, equipment rental, mobile repair, trades	Captures all time	Must be disclosed clearly
One-way only	Bill travel to the site, not the return	Some trades and consultants	Compromise approach	Loses half the time
Flat trip or zone fee	Fixed fee per visit or distance band	Home services, mobile businesses	Predictable for clients	Can lose money on long trips
Travel day rate	Fixed amount per day spent traveling	Out-of-town consulting, events, crews	Simple for long trips	Needs clear definition of a travel day
Mileage only	Per-mile charge, no time	Local services, delivery	Easy to verify	Does not pay for your hours

How much should you charge for travel time?

There is no legal rate for billing clients; it is a commercial decision. Consider:

• Opportunity cost: if travel prevents you from serving another paying client, full rate is justified.
• Productivity while traveling: if you can work on a train or plane for the client, bill that work as normal time instead of travel time.
• Market norms: half rate for travel is a widely used compromise among consultants and freelancers.
• Service area: many businesses absorb travel within a core area (say 15 or 20 miles) and charge only beyond it.

Mileage rates

For vehicle costs, many businesses use the IRS business standard mileage rate as a benchmark when billing clients. For 2026 the IRS initially set it at 72.5 cents per mile and later raised it mid-year; check the IRS standard mileage rates page for the rate that applies to your travel dates. Clients are not obliged to accept the IRS rate, and you can charge more or less by agreement. Our IRS mileage rate 2026 guide and standard mileage vs actual expenses explain the tax side, and a mileage log template helps you keep records.

Worked example 1: local trade, portal-to-portal

A mobile welding service charges $95 per hour portal-to-portal, with a one-hour minimum, plus $1.25 per mile beyond 20 miles round trip. A job 28 miles away (56 miles round trip) takes 2 hours on site and 1 hour 10 minutes of driving in total.

Description	Qty	Rate	Amount
Labor, on-site welding repair: trailer hitch frame (October 28, 2026)	2.0 hrs	$95.00	$190.00
Travel time, portal-to-portal (depart shop 8:05 a.m., return 11:15 a.m.; driving 1.17 hrs)	1.17 hrs	$95.00	$111.15
Mileage beyond 20-mile included radius (56 - 20 miles)	36 mi	$1.25	$45.00
Welding rod and consumables	1	$22.00	$22.00
Subtotal			$368.15

See our welding invoice template for a full layout.

Worked example 2: consultant, out-of-town trip at half rate

A consultant billing $160 per hour agrees with the client: travel time at 50% ($80 per hour), capped at 8 billable travel hours per trip, plus flights and hotel at cost. The trip involves 6.5 hours of door-to-door travel each way (13 hours total).

Description	Qty	Rate	Amount
On-site workshop facilitation, November 4 to 5, 2026	14 hrs	$160.00	$2,240.00
Travel time at 50% rate (13 hrs actual, capped at 8 per agreement)	8 hrs	$80.00	$640.00
Airfare, economy (receipt attached)	1	$412.60	$412.60
Hotel, 2 nights (receipt attached)	2	$189.00	$378.00
Airport parking	1	$54.00	$54.00
Total			$3,724.60

Showing the actual hours and the cap builds trust: the client can see they are getting a discount. See the consulting invoice template for more examples and our hourly invoicing guide for tracking time.

How to word travel terms in a contract or estimate

• "Travel within 20 miles of our shop is included. Beyond that, travel time is billed at $95/hr portal-to-portal and mileage at $1.25/mile."
• "Travel time is billed at 50% of the standard hourly rate, up to a maximum of 8 hours per round trip. Work performed while traveling is billed at the standard rate."
• "Out-of-town engagements include a travel day fee of $600 per travel day plus reasonable expenses at cost, with receipts."
• "A minimum travel charge of 30 minutes applies to each visit."
• "When one trip serves several clients, shared travel time and expenses are divided equally among them."

Put the agreed wording in your service agreement, estimate or freelance contract so the invoice simply applies what was already agreed.

How to show travel time on an invoice: step by step

1. Log it as it happens: departure and arrival times, start and end mileage, and the purpose of the trip.
2. Apply the agreed method: rate, minimum, cap and included radius.
3. Use separate lines for travel time, mileage and each type of expense.
4. Describe each line with dates, route or times and the rate basis.
5. Attach receipts for reimbursed expenses if the client requires them.
6. Check tax treatment for your state; our sales tax calculator helps with the arithmetic.
7. Generate the invoice in a consistent format, for example in our free invoice generator.

How to split travel across several clients

When one trip serves more than one client, bill each client a fair share instead of the whole trip. Example: a photographer drives 3 hours (round trip) and 140 miles to shoot two events for two clients in the same city, with 1 extra hour and 20 miles to reach the second venue.

Cost	Shared or specific	Client A	Client B
Main round trip, 3 hrs at $50/hr travel rate	Shared equally	$75.00	$75.00
Extra leg to second venue, 1 hr	Client B only	$0.00	$50.00
Mileage, 140 mi at $0.70	Shared equally	$49.00	$49.00
Extra mileage, 20 mi at $0.70	Client B only	$0.00	$14.00
Travel billed		$124.00	$188.00

Each invoice should say "shared travel, split between two clients" so the client understands why the figure is lower than the full trip. Document the split in your records in case either client asks.

Travel billing by profession

Profession	Common approach
Plumbers, HVAC, electricians	Flat trip charge locally; portal-to-portal for remote jobs
Consultants and trainers	Travel at 50% to 100% of rate, plus expenses at cost
Lawyers and accountants	Travel billed hourly per engagement letter, sometimes reduced
Photographers, DJs, makeup artists	Free within a radius, then per-mile or flat travel fee; see makeup artist rates
IT and managed service providers	On-site visit fee or minimum hours; remote support has none
Home health and mobile care	Often absorbed into visit rates; mileage may be reimbursed

Billing travel time vs paying employees for travel

Do not confuse what you bill clients with what you must pay staff. For US employers, the Fair Labor Standards Act and the Portal-to-Portal Act govern when employee travel is compensable: travel between job sites during the workday is generally working time for nonexempt employees, while normal commuting from home is generally not. The Department of Labor's guidance on hours worked explains the rules. Your client billing policy can be more or less generous than your payroll obligations, but your payroll must still follow the law.

Common mistakes when billing for travel

• Not agreeing it in advance. Travel is the line item clients most often dispute.
• Double charging: a trip charge plus full travel time plus mileage for a short local trip.
• Billing a full trip to several clients. Split shared travel.
• Billing commute-style travel from home to a regular client site you visit daily, when the client expects it absorbed.
• Vague lines like "Travel: $200" with no hours, miles or dates.
• No records. Without a log, you cannot defend the charge or support tax deductions.
• Charging work rate for travel when you also billed work done in transit for the same hours.

Billing for travel time is fair and expected when the method is agreed upfront and shown transparently on the invoice. Choose a method that fits your work, log the hours and miles, and give each charge its own clear line.
