How Fuel-Savings Payback Calculator Works
This tool works by dividing the added purchase cost of a more efficient option by the yearly fuel saving it delivers.
- Step 1
Enter the added cost
Type the extra purchase price, such as a hybrid premium or a fuel-saving upgrade.
- Step 2
Enter the fuel saving
Type the yearly fuel saving, or enter miles, both MPG values, and price.
- Step 3
Enter the ownership period
Type the years you plan to keep the vehicle or equipment.
- Step 4
Read the payback
The calculator shows payback in years and months and the net gain over ownership.
Fuel-Savings Payback Calculator Formula
The formula divides added cost by annual fuel saving.
Payback (years) = Added Purchase Cost ÷ Annual Fuel Saving
Net Gain = Annual Fuel Saving × Years Owned − Added Purchase Cost
- Added Purchase Cost
- = extra price of the efficient option
- Annual Fuel Saving
- = yearly fuel money saved by that option
Worked Example
- A hybrid costs $2,500 more than the gas version and saves $560 per year in fuel.
- Payback = $2,500 ÷ $560 = 4.46 years (54 months).
- Over 8 years of ownership, net gain = $560 × 8 − $2,500 = $1,980.
- Selling at year 3 leaves $820 unrecovered.
Fuel-Savings Payback Calculator Conversion Table
The table lists payback periods in years for added costs and yearly fuel savings.
| Added Cost | Saving $300 / yr | Saving $500 / yr | Saving $800 / yr | Saving $1,200 / yr |
|---|---|---|---|---|
| $500 | 1.7 yr | 1.0 yr | 0.6 yr | 0.4 yr |
| $1,000 | 3.3 yr | 2.0 yr | 1.3 yr | 0.8 yr |
| $2,000 | 6.7 yr | 4.0 yr | 2.5 yr | 1.7 yr |
| $2,500 | 8.3 yr | 5.0 yr | 3.1 yr | 2.1 yr |
| $3,500 | 11.7 yr | 7.0 yr | 4.4 yr | 2.9 yr |
| $5,000 | 16.7 yr | 10.0 yr | 6.3 yr | 4.2 yr |
| $7,500 | 25.0 yr | 15.0 yr | 9.4 yr | 6.3 yr |
What is a Fuel-Savings Payback Calculator?
A Fuel Savings Payback Calculator is an investment tool that compares an added purchase cost with the fuel savings it produces and finds the break-even time.
Efficient vehicles and fuel-saving equipment cost more up front. The question is whether the fuel saving repays that cost before the owner sells. The Fuel Savings Payback Calculator gives the payback time and the net gain across the ownership period.
Payback shortens with higher mileage and higher fuel prices. Run the calculation at 2 or 3 price levels for a full picture.
What are the uses of a Fuel-Savings Payback Calculator?
There are 4 main uses of the Fuel Savings Payback Calculator, including hybrid decisions, upgrade decisions, and fleet investment cases.
