Chevrolet Fuel Cost Calculator Guide: How to Estimate Your Driving Expenses
Figuring out how much you’ll spend on gas or electricity for your Chevy doesn’t have to be guesswork—a simple fuel cost calculation can help you budget better and pick the right model for your wallet.
TL;DR
Fuel costs vary dramatically across Chevrolet’s lineup, from around $800 a year for efficient EVs to over $2,600 for powerful V8 trucks. The easiest way to estimate your costs is using fueleconomy.gov’s calculator, where you enter your mileage and fuel prices to get personalized numbers. This guide breaks down the fuel costs for popular Chevy models, shows you how to do the math yourself, and compares gas, diesel, and electric options so you can make a smarter choice.
Key Takeaways
- MPG matters most: A 30 MPG Chevy Trax costs about $2,000 a year to fuel, while a 17 MPG Silverado V8 runs about $2,600 .
- EVs are much cheaper to “fuel”: The Equinox EV costs roughly $800–$900 per year, compared to $1,700+ for gas models .
- Diesel saves money on trucks: The Silverado diesel 2WD gets 26 MPG combined and costs around $1,750 annually—better than the gas V8’s $2,600 .
- E85 costs more despite being cheaper per gallon: It takes more E85 to go the same distance as gas, so annual fuel costs often end up higher .
- Use the government’s calculator: The fueleconomy.gov tool lets you personalize estimates with your local fuel prices and driving habits.
How to Calculate Your Chevy’s Fuel Costs
Here’s the simple formula for estimating annual fuel costs:
Annual Fuel Cost = (Annual Miles Driven ÷ MPG) × Fuel Price
For example, if you drive 15,000 miles a year in a Silverado that gets 17 MPG, and gas costs $3.00 a gallon:
(15,000 ÷ 17) × $3.00 = 882 gallons × $3.00 = $2,646 per year
For EVs, the formula is similar but uses electricity rates instead of gas prices:
Annual Fuel Cost = (Annual Miles Driven ÷ MPGe) × Electricity Rate
The fueleconomy.gov website does this math for you, letting you adjust for your local fuel prices and driving habits. It’s the most accurate way to get a personalized estimate .

Gas vs. Diesel vs. Electric: Which is Cheaper to Fuel?
Electric vehicles are the clear winners for fuel savings. The Equinox EV costs about $800 a year to run, compared to $1,700 for the gas Equinox—a savings of roughly $900 annually . Over five years, that adds up to about $4,500.
Diesel trucks offer significant savings over their gas counterparts. The Silverado diesel saves about $850 a year compared to the 5.3L V8 gas version . The diesel also produces lower greenhouse gas emissions (399 grams/mile vs. 468 grams/mile for the gas V8) .
E85 is a mixed bag. While E85 is often cheaper per gallon, vehicles get lower MPG on it, so annual costs can be higher. For example, the Silverado 4WD V8 costs $2,600 on gas but $3,300 on E85 . The Trax costs $2,000 on gas and $1,800 on E85—a rare case where it comes out slightly ahead .
