Payback Period and Fuel Savings

Before installing a Start fuel saving device on your vehicle, you naturally will want to know:

- How quickly you will recoup your investment (payback period)

- How much money you will save over time

based on a unit cost of \$2,025 USD1, average annual distance traveled of 100,000 miles and average fuel savings of 15%2, most long-haul trucks will experience Payback on their purchase in 50 to 70 days.

How to Calculate Payback Period

The following two formulas can be used to calculate the Payback Period for your vehicle.

Formula 1

Step 1: (annual fuel cost) x (15% saving) / (365 days) = (daily fuel savings)

Step 2: (unit cost) / (daily fuel saving) = Payback Period.

Example Annual Fuel Cost: \$73,000 (Equivalent to daily fuel cost of \$200)

Unit Cost: \$2,025 USD

Results:
Payback Period: 68 days

Formula 2

Step 1: (annual miles driven per vehicle) x (fuel cost per U.S. gallon) x (15% savings) / (average miles per U.S. gallon (MPG)) = (annual savings)

Step 2: (annual savings) / (365) = (daily savings)

Step 3: (unit cost) / (daily savings) = Payback Period

Example
Annual Miles Driven Per Vehicle: 100,000

Average Miles Per U.S. Gallon (MPG): 5

Fuel Cost Per U.S. Gallon: \$4 USD

Results
Payback Period: 61
- Annual Fuel Cost: \$20,000
- Annual Savings: \$3,000
