Estimate Fuel and Mileage Cost

Copy

I charge mileage at a rate I picked years ago and I do not know if it covers anything. Build me a fuel and mileage calculator. Keep a vehicles project with each vehicle real average consumption, its fuel type and any known running cost per mile such as servicing and tyres. Keep the current fuel price per unit as an editable record. Let a journey be entered with distance, vehicle and job, and get the fuel cost, the total running cost and the amount recharged at my current rate, with the difference shown. Roll it up per job, per vehicle and per month. Add an AI agent that reviews the last quarter and tells me which vehicles and which customer areas cost the most to serve, and whether my recharge rate is covering the true cost. Automate a scheduled monthly reminder to update the fuel price and a monthly report on cost recovery. Two logins: a driver who logs journeys from a phone, and an owner who sets rates.

Estimate Fuel and Mileage Cost

Work out real fuel cost per journey, job, and vehicle from actual consumption and current prices, against what you recharge.

// the spark catches · intelligence awakens · the answer unfolds

Mileage is charged from habit and costed from nothing. This works out the real figure per vehicle so recharges and job pricing are based on something.

What's Included

  • Cost per journey and per job using each vehicle real consumption.
  • Fuel price as editable data because it moves constantly.
  • Recharge rate against real cost so you can see the gap.
  • An assistant that finds the vehicles and routes costing most.

How To Use

  1. Use each vehicle real consumption, not the manufacturer figure.
  2. Update fuel price monthly. A stale price makes the whole thing wrong.
  3. Compare what you recharge against what it costs. The gap is often large.
  4. Attribute cost to jobs so unprofitable travel becomes visible.

Price it into quotes with the callout fee calculator, and run the fleet with field service prompts.
