How Fleet Efficiency Savings Calculator Works?
This tool works by comparing fleet fuel use at a baseline of 18 miles per gallon (MPG) with fuel use after an MPG increase, then pricing the gallons saved at $3.65.
Enter the number of vehicles
Type the vehicles in the fleet, for example 25.
Enter miles per vehicle per year
Type yearly miles per vehicle, for example 20,000 miles (32,187 km).
Enter the MPG increase
Type the gain over the 18 MPG baseline, for example +3 MPG.
Read the annual saving
The tool returns yearly fleet fuel savings.
Fleet Efficiency Savings Calculator Formula
The formula is Savings = ((Vehicles × Miles ÷ 18) − (Vehicles × Miles ÷ (18 + MPG Increase))) × $3.65.
Savings = ((V × Miles ÷ 18) − (V × Miles ÷ (18 + Increase))) × $3.65Formula variables
- V × Miles
- Total yearly fleet miles.
- 18
- Fixed baseline fleet MPG.
- 18 + Increase
- Improved fleet MPG.
Worked example
- Number of Vehicles: 25 vehicles
- Miles per Vehicle / Year: 20,000 miles
- MPG Increase (+3 MPG): 3 MPG
- Fleet miles: 25 × 20,000 = 500,000 miles.
- Baseline gallons: 500,000 ÷ 18 = 27,777.78.
- Improved gallons: 500,000 ÷ 21 = 23,809.52.
- Savings: 3,968.25 × $3.65 = $14,484.13 per year.
Result: $14,484.13 ($ annual fleet savings)
A 3 MPG gain from 18 to 21 MPG cuts fleet fuel use by 14.3%. Driver training, idle reduction, tire programs, and route planning each deliver 2% to 10% MPG gains.
Fleet Efficiency Savings Calculator Conversion Table
The table shows annual savings for 4 fleet sizes at 3 MPG increases, with 20,000 miles per vehicle.
Rows: Number of Vehicles (vehicles). Columns: MPG Increase (+3 MPG) (MPG). Cells: $ annual fleet savings.
| vehicles | 1 MPG | 3 MPG | 5 MPG |
|---|---|---|---|
| 10 vehicles | $2,134.50 | $5,793.65 | $8,816.43 |
| 25 vehicles | $5,336.26 | $14,484.13 | $22,041.06 |
| 50 vehicles | $10,672.51 | $28,968.25 | $44,082.13 |
| 100 vehicles | $21,345.03 | $57,936.51 | $88,164.25 |
Values held constant: Miles per Vehicle / Year = 20,000 miles.
A 100-vehicle fleet that gains 5 MPG saves $88,164.25 per year in fuel.
What is Fleet Efficiency Savings Calculator?
The Fleet Efficiency Savings Calculator is a tool that measures the yearly fuel saving from raising fleet fuel economy. The tool values efficiency programs in dollars.
Small MPG gains add up across many vehicles and many miles. A 1 MPG gain on a 25-vehicle fleet saves over $5,000 per year at the default settings.
The calculator uses an 18 MPG baseline, typical of mixed van and pickup fleets.
What are the uses of Fleet Efficiency Savings Calculator?
There are 4 main uses of the Fleet Efficiency Savings Calculator: justifying driver training, valuing telematics systems, approving vehicle upgrades, and setting fleet efficiency goals.
Justifying driver training
Managers compare training costs with fuel savings.
Valuing telematics systems
Fleets value tracking systems that cut idling and speeding.
Approving vehicle upgrades
Buyers price the saving of more efficient replacement vehicles.
Setting fleet efficiency goals
Managers set MPG targets tied to dollar savings.
