How We Select the Best Credit Cards for Gas and EV Charging?
To identify the best credit cards for gas and EV charging, we analyzed more than 120 leading credit cards issued by FDIC-insured banks and widely available in the United States. From this pool, we narrowed the list to roughly 70 cards that offer rewards on gas purchases or EV charging, including cash back, points, and travel rewards cards.
For gas spending, we estimated each card’s annual rewards potential using average household fuel expenses. According to the most recent data from the Bureau of Labor Statistics (BLS), the average U.S. household spent approximately $2,411 on gasoline in 2024 (about $201 per month). Because gas represents a meaningful and recurring expense, reward efficiency in this category plays an important role in overall card value.
Gas Rewards Analysis
When comparing gas credit cards, we placed significant weight on earning power for fuel purchases. Specifically, we evaluated:
- Reward rate: cashback percentage or equivalent rewards value at gas stations
- Earning structure: spending caps, quarterly limits, rotating categories, or activation requirements
- Earning simplicity: how consistently and easily rewards can be earned in real-world use
- Redemption flexibility: cashback options, statement credits, transfer partners, travel redemption, etc.
- Redemption value and rates
A key metric in our analysis is the estimated annual rewards a cardholder could generate from gas spending alone. Using average U.S. household fuel expenses from the Bureau of Labor Statistics, we model both typical spending scenarios and high-spend scenarios to capture the full range of potential value.
We then apply a second layer of evaluation using each card’s overall Big4credit rating. While gas earning power determines category eligibility, final selections prioritize cards that combine strong rewards with high overall performance across our unified scoring framework.
This ensures that featured cards excel both in fuel-related spending and as well-rounded financial products.
EV Charging Rewards Analysis
For EV charging, we prioritize credit cards that offer elevated rewards at EV charging stations, typically requiring a minimum of 3% back (or equivalent rewards value) to qualify for this category.
Cost and Risk Factors
In addition to rewards, we evaluate key cost and financing factors that impact the overall value of gas and EV charging credit cards, including:
- Annual fees
- Foreign transaction fees
- Ongoing APR
- Introductory 0% APR offers on purchases
Many of the best cards in this category have no annual fee, making it easy to earn rewards on everyday fuel or charging expenses without added cost. However, some cards with annual fees may still deliver strong overall value if their rewards rates, credits, or additional benefits outweigh the fee.
We also consider foreign transaction fees, particularly for drivers who travel internationally or rent vehicles abroad, where fuel or charging purchases may incur extra costs. Introductory 0% APR offers can provide short-term flexibility, but long-term interest rates remain an important factor for cardholders who carry a balance.
Additional Evaluation Criteria
Beyond rewards and costs, we also consider:
- Welcome bonus value and first-year earning potential
- Travel protections
- Additional perks and benefits
Welcome bonuses can add meaningful first-year value if the spending requirement is realistic. We evaluate both the size of the bonus and how achievable it is, ensuring it reflects true, attainable value for most cardholders.
We also assess protections and perks that may be relevant for everyday driving and travel, such as travel protection, travel-related benefits, or roadside assistance, where available.
All rankings in this category reflect both gas and EV charging earning potential and the card’s overall strength within our broader Big4credit methodology.
