Two Amazon DSPs shut down this spring with almost no warning. Here's what the numbers say before a closure happens.

Blue Thunder Logistics in Weston, Wisconsin gave its 80–100 drivers two days notice before shutting down April 3, according to WAOW and WSAU. Six weeks before that, Smoky Mountain Logistics in Lebanon, Tennessee closed with 145 layoffs, per NewsChannel 5.

Both were operating Amazon routes. Both closed abruptly.

I keep seeing people online treating this like a bolt from the blue. It never is. The math gets there first — usually by months. Here's what it looks like before it happens.

The cost structure that makes DSPs fragile

Running an Amazon DSP at steady state costs $6,800–$6,930 per van per month fully loaded. That's:

• $620 financing
• $180 insurance
• $422 fuel
• $5,065–$5,195 driver cost per van

Source: Pexara fleet benchmark data.

At a $12/stop rate and 1,320 stops per van per month (60 stops/day, 22 days), you're making $15,840/van in revenue. That's $8,910 margin per van per month.

Sounds decent. Here's the problem.

Three things that move that margin to zero

1. Rate compression

Amazon sets the per-stop rate. You don't negotiate it the same way you'd negotiate a commercial contract. When it moves, the impact scales hard:

| Rate cut | Per van/yr | 20-van fleet | 50-van fleet | |---|---|---|---| | 5% | −$2,950 | −$59,000 | −$147,500 | | 10% | −$5,900 | −$118,000 | −$295,000 | | 15% | −$8,850 | −$177,000 | −$442,500 |

Source: Pexara fleet rate compression model.

A 10% rate cut on a 20-van fleet is $118,000/year. That's not a rounding error.

2. Maintenance inflation

Fleet maintenance CPI is up 46.8% since 2019, per Pexara benchmark data.

The numbers you're running maintenance against — if they're from 2022 or older — are wrong. A Transit that ran $888/year in maintenance in 2019 is closer to $1,302 now in equivalent dollars. A Sprinter that ran $1,778 is closer to $2,611.

You probably haven't repriced that assumption.

3. Driver turnover

80% annual turnover in the DSP sector, per Bureau of Labor Statistics JOLTS (NAICS 4921).

Replacing a driver costs $3,500–$5,500 per hire, per SHRM's 2024 non-CDL benchmarking data.

20-van fleet, 80% turnover = 16 replacements/year = $56,000–$88,000 in churn cost. Every year. It doesn't show up on your per-stop rate. It shows up in your quarterly P&L wondering where the margin went.

The number that actually tells you where you are

Cost per stop.

Divide your total monthly cost per van ($6,800–$6,930) by your monthly stop count (1,320 typical). Fully loaded, that's $5.15–$5.25 per stop.

Your per-stop rate from Amazon is a separate number. The gap between those two is your margin.

When that gap closes — through rate compression, cost inflation, or compounding turnover — the P&L catches it after the fact. Cost per stop catches it in real time.

Insurance Journal published a piece in October 2025 saying Amazon delivery firms were "bailing amid rising costs and meager profit." That was six months before Blue Thunder closed in April. The operators who read that trend and made a calculated exit on their own terms are in a different position than the ones who got two days' notice.

TL;DR

$5.15–$5.25/stop is your fully loaded cost. Whatever Amazon is paying you per stop is your revenue. That gap is your business. When rate cuts, maintenance inflation, and driver churn compress it from all three sides at once, the math gets there before the announcement does.

Know the number. Not an estimate. The number.
