Hotshot Empty Mile Percentage: Measure Your Deadhead Exposure
Hotshot empty mile percentage is the share of total miles you drive without a load, calculated as empty miles divided by total miles driven, then multiplied by 100. For independent hotshot operators, owner-operators, and small freight carriers, it’s a practical way to measure deadhead exposure before deciding whether a load is actually worth hauling.
This section shows how to define and calculate the percentage correctly, keep your measurements consistent so the ratio means something, and compare one load or operating pattern against another without distorting the denominator. Used well, empty-mile percentage helps you spot unpaid travel, judge load profitability more accurately, and make better cost and routing decisions across your freight operation.
Use a consistent definition
Empty-mile percentage equals empty miles divided by total miles, multiplied by 100. Count loaded and empty miles over the same period. Define whether personal miles, maintenance trips and bobtail travel are included so comparisons remain meaningful.
A worked example
Suppose your truck travels 8,000 total business miles in a month, including 1,600 empty miles. Empty-mile percentage is 1,600 ÷ 8,000 × 100 = 20%. The remaining 6,400 miles are loaded miles under these assumptions.
Do not divide by loaded miles or deadhead miles
Dividing 1,600 by 6,400 produces 25%, but that measures empty miles relative to loaded miles, not the percentage of all miles driven empty. Both ratios can be useful, but they are not interchangeable.
Why the ratio matters
A higher empty-mile share means more deadhead miles, and miles cost money even when the truck is not hauling cargo. The actual financial impact depends on the miles, equipment, route, and operating costs, with fuel costs, maintenance costs, and added wear and tear all cutting into profit when you are pulling an empty trailer. The marginal cost of empty travel varies by vehicle, fuel consumption, tire wear and route. Do not infer a universal maintenance charge, target profit margin or accident-risk multiplier from the empty-mile percentage alone.
Compare similar periods to better plan routes
Seasonality, geography, dedicated contracts and freight mix can change empty-mile share. Compare routes and months using the same definitions, and judge any target only against a similar freight type, geography, and operating model rather than assuming a universal target applies to every operator.
Empty-mile percentages vary by fleet type, lanes, operating strategy and measurement method. Use your own historical miles as the primary benchmark.
Set a target based on your available reload opportunities and the cost of repositioning; a lower percentage is not always better if it requires declining profitable loads.
Turn measurement into decisions about fuel costs
Make it a weekly plan to track empty mile percentage before pickup, after delivery, and between jobs separately, along with related KPIs, because tracking empty-mile KPIs weekly helps identify operational inefficiencies and improve route efficiency. Dropping a load in a remote area often raises empty miles before the next load, while high-density freight hubs make backhauls easier to find. To avoid deadheading, book pre-planned outbound freight and plan around backhauls, since that can reduce empty miles and support more profitable trips. Use total-mile revenue and operating profit alongside empty-mile percentage: minimizing deadhead alone does not guarantee a better load. Before the final review, use load boards to find loads and check available freight from brokers, shippers, and other carriers, line up a return trip, and plan routes around the next load.
