Every time a CDL-A driver quits, your fleet pays twice: once to find and onboard the replacement, and again for every day that truck sits without someone in the seat. Most carriers track the first cost loosely and never track the second at all. This guide breaks down the real truck driver turnover cost per driver, walks through a worked example you can adapt to your own numbers, and shows where the savings actually are.
Why truck driver turnover cost matters more in 2026
Driver mobility is climbing again. A spring 2026 survey by Conversion Interactive Agency and People. Data. Analytics. found that 58.1% of drivers were looking for a new driving job, up from 46.8% a year earlier, according to Transport Topics. The same coverage cites PDA research putting the cost of losing a driver at about $13,000.
At the same time, there is very little margin left to absorb that expense. ATRI's latest Operational Costs of Trucking report found the average cost to run a truck reached a record $2.336 per mile in 2025, while truckload operating margins were below 1%. ATRI also reported that carriers left about 10% of their trucks unseated on average. When your margin is measured in pennies, a five-figure loss every time a driver walks is not a rounding error.
What goes into the cost of replacing a driver
The most widely cited study on this topic, from the Upper Great Plains Transportation Institute, put the average replacement cost at $8,234 per driver, as reported by Transport Topics. That figure is in 2000 dollars, so today's number is meaningfully higher. More important than the headline number is the list of cost buckets, because that is where you find the money:
- Recruiting: job board fees, social media ads, sign-on or referral bonuses, and the leads you pay for that never convert.
- Recruiter and admin time: calls, follow-ups, application review, verification of employment, and building the DQ file.
- Screening: drug test, MVR, PSP report, Clearinghouse query, DOT physical and road test.
- Orientation: travel, hotel, meals, orientation pay, and trainer or safety staff time.
- The empty seat: lost revenue and fixed costs that keep running while the truck waits for a driver.
- Ramp-up and risk: new drivers typically take time to learn your lanes, customers and systems, and early tenure is when accidents and quits are most likely.
Most fleets only count the first two or three buckets. The last two are usually the largest.
A worked example: what one driver quit costs a small fleet
The numbers below are assumptions for illustration, not industry averages. Swap in your own figures.
- Recruiting spend per hire: assume $2,000 in ads and bonuses divided across the drivers you actually seat.
- Recruiter time: assume 20 hours per seated driver at a loaded cost of $30/hour = $600.
- Screening: assume $250 for drug test, MVR, PSP, Clearinghouse and physical.
- Orientation: assume 3 paid days at $200/day plus $600 for travel and hotel = $1,200.
- Empty seat: assume the truck sits for 3 weeks. ATRI puts truck and trailer payments at roughly 40 cents per mile; on a truck that normally runs 2,000 miles a week, that is about $800 a week in equipment cost that stays due whether the truck moves or not. Add an assumed $1,500 a week in lost contribution to overhead and profit. Three weeks = about $6,900.
Total: roughly $10,950 per driver replaced, before you count ramp-up time or any lost customer freight. That lands in the same range as the PDA estimate. Now scale it: if a 20-truck fleet replaces 14 drivers in a year (an assumed 70% turnover rate), that is about $153,000 a year. On sub-1% margins, you would need millions in additional revenue just to cover it.
Notice that the empty seat is the biggest single line. That is why speed matters as much as cost per hire. Cutting the vacancy from three weeks to one saves more in this example than eliminating your entire ad budget.

How to calculate your own turnover cost in one afternoon
- Pull last year's separations. Count every driver who left, voluntary or not, and divide by your average number of seated drivers. That is your turnover rate.
- Add up hard recruiting costs. Job boards, ads, bonuses, screening fees and orientation travel for the year. Divide by drivers hired, not applications.
- Estimate people time. Recruiter, safety and orientation staff hours spent on hiring, times their loaded hourly cost.
- Measure time-to-seat. Average the days between a driver leaving and the replacement dispatching on that truck. Multiply by your weekly fixed cost per truck and your average weekly contribution per truck.
- Divide the total by replacements. That is your cost per turnover. Put it in front of dispatch, safety and ownership every quarter.
Once you have a real number, retention spending becomes an easy business case. A $1,000 retention bonus, a better truck assignment or an extra home-time day stops looking expensive next to a five-figure replacement.
Where to cut turnover cost first
- Fix the first 90 days. Early quits are the most expensive because you paid the full hiring cost and got little productive time back. Structured check-ins, reliable first-week miles and a clean truck make a measurable difference. Our 90-day retention plan lays out a week-by-week approach.
- Shrink time-to-seat. Keep a warm pipeline of pre-qualified drivers so a resignation turns into an orientation date within days, not weeks. Run MVR, PSP and Clearinghouse checks in parallel instead of one after another.
- Track turnover by source and by dispatcher. If one recruiting channel or one driver manager produces drivers who leave in 60 days, that is where your money is leaking.
- Do real exit interviews. Ask about pay accuracy, home time, miles and equipment. Tie each answer to a dollar figure using your cost per turnover.
- Be accurate in recruiting. Overpromising miles or home time during recruiting creates quits in week three. Honest job descriptions filter out mismatches before you spend on orientation.
Key takeaways
- Replacing one CDL-A driver commonly costs in the low five figures once you include the empty seat; PDA research puts it at about $13,000.
- Driver job-seeking jumped to 58.1% in spring 2026, so turnover pressure is rising while carrier margins remain thin.
- The unseated truck is usually the biggest cost line, so time-to-seat matters as much as cost per hire.
- Calculate your own cost per turnover with five data points you already have, and use it to justify retention spending.
- Focus first on the first 90 days, time-to-seat and recruiting accuracy.
When it makes sense to get help
Lowering turnover cost takes two things at once: keeping the drivers you have and refilling empty seats fast with drivers who fit. If your recruiters are already stretched between answering calls, chasing paperwork and covering safety, a recruiting partner that is paid only when a driver is seated and still on the job can shorten your time-to-seat without adding fixed overhead.
