It's a simple calculation, but everything starts with the postcode.

The database include more than 3Million postcodes, though for the purpose of the calculation, they're not used, rather I use the postcode to find the Longitude and Latitude coordinates.

Using the Google Maps API, a route is created, along with a distance, from here we calculate the amount of diesel used (current prices and vehicle efficiency), and I add for labour costs, that's it, the equation is;

$totalCost = ($distance * $fuelCostPerMile) + ($distance / 56 * $labourCostPerHour)
