Formula Used
Direct miles: calculated with the haversine method using origin and destination coordinates.
Base miles: odometer miles are used when entered. Otherwise, direct miles are used.
Route adjusted miles: base miles × (1 + route factor ÷ 100).
Stop miles: number of extra stops × average miles per stop.
Billable miles: route adjusted miles + stop miles + empty miles.
Statistical buffer: billable miles × ((confidence z score × standard deviation percentage) ÷ 100).
Planning miles: billable miles + statistical buffer.
Total revenue: linehaul revenue + fuel surcharge amount + accessorial revenue.
Total cost: fuel cost + driver cost + maintenance cost + tolls + fixed cost.
Profit margin: profit ÷ total revenue × 100.

Direct Freight Mileage Planning Guide
Why Mileage Matters
Freight mileage affects nearly every shipment decision. A small mileage error can change price, fuel cost, driver pay, and margin. Direct distance gives a clean starting point. Yet freight rarely moves in a perfect straight line. Roads, bridges, stops, traffic rules, and delivery limits all add practical miles.
Using Direct Distance
This calculator starts with latitude and longitude. It estimates direct distance between two points. That number is useful for lane comparison. It also gives a neutral baseline. Dispatchers can compare different loads without depending only on map quotes or carrier guesses.
Adding Route Reality
A route factor changes direct miles into practical miles. Higher factors may fit mountain roads, city delivery, port moves, or restricted truck routes. Lower factors may fit simple highway lanes. Extra stops and empty miles are also added. This creates a better billable mileage estimate.
Statistical Buffer
The statistical section helps with uncertainty. Standard deviation shows how much past route mileage can vary. The z score controls how conservative the plan should be. A larger z score adds more buffer. This is useful when pricing risky lanes or protecting thin margins.
Cost and Revenue Review
The calculator also estimates fuel, driver pay, maintenance, tolls, and fixed dispatch cost. Revenue includes linehaul, fuel surcharge, and accessorial charges. Profit is the amount left after cost. Margin shows profit as a percent of revenue.
Better Freight Decisions
Use this tool before quoting, booking, or reviewing a shipment. It helps compare lanes with consistent assumptions. It also shows whether a load pays enough for the miles. Clean mileage planning supports better pricing, safer dispatching, and stronger carrier performance.
FAQs
What is direct freight mileage?
Direct freight mileage is the straight-line distance between pickup and delivery points. It is useful as a baseline before route factors, empty miles, and stops are added.
Why is a route factor needed?
A route factor adjusts direct miles for real roads. It covers detours, highways, truck restrictions, terrain, and city routing that can increase actual travel distance.
What are empty miles?
Empty miles are miles driven without freight. They may occur before pickup or after delivery. They should be included when judging lane profitability.
What does the statistical buffer mean?
The statistical buffer adds mileage protection based on standard deviation and z score. It helps estimate a safer planning distance when lane mileage varies.
Should I use odometer miles?
Use odometer miles when you already know actual route distance. If it is entered, the calculator uses it instead of coordinate-based direct mileage.
How is profit calculated?
Profit equals total revenue minus total cost. Revenue includes linehaul, fuel surcharge, and accessorial revenue. Cost includes fuel, driver pay, maintenance, tolls, and fixed cost.
Can this calculator price a freight lane?
Yes. It can estimate linehaul revenue, cost per mile, revenue per mile, and profit margin. Use current market rates for better results.
Is this calculator useful for dispatchers?
Yes. Dispatchers can estimate practical miles, compare shipment options, add buffers, review costs, and export results for quick lane planning.
