Fleet Accident Cost Calculator — True Cost of a Commercial Vehicle Accident

Calculate the true cost of a commercial vehicle accident. Beyond repair — liability exposure, cargo damage, driver injury, downtime, premium increase, and the nuclear verdict risk that terrifies fleet managers.

Quick answer: Average commercial vehicle accident cost: $148,000 (ATRI). Fatal truck accident: $3.6M average. Minor accident with injury: $500K–$2M after litigation. Insurance deductible is just 5–10% of true accident cost.

How to Use This Calculator

Select severity and adjust defaults — defaults are set to typical values for each severity level — adjust for your actual history.
Enter revenue per day — downtime is the most underestimated cost — a truck off the road for 12 days loses 12 days of revenue.
Use result to build safety program ROI — a $50K/year safety training and telematics program that prevents one moderate accident saves $50K–$150K.

Worked Example

3 accidents/year, moderate severity, $5K deductible, $8.5K premium increase, 12 days downtime, $1,400/day revenue.

True cost/accident: $5K + $25.5K + $16.8K + $15K + $4.5K = $66,800
Annual fleet cost: $200,400
Deductible is: only 7.5% of true cost

Many fleet managers focus only on the deductible. The premium increase alone (3 years × $8,500) exceeds the deductible — and downtime adds another $16,800. Total cost is 13× the deductible.
