How EV vs gas savings are calculated
The math is straightforward — compare the annual energy cost of driving each car the same number of miles:
EV annual cost = (miles / mi-per-kWh) × electricity rate
Gas annual cost = (miles / MPG) × gas price
Annual savings = gas cost − EV cost
At national averages — 12,000 miles, 3.5 mi/kWh EV, $0.16/kWh, 25 MPG gas car, $3.45/gal — that's $549 EV cost vs $1,656 gas cost = $1,107 annual fuel savings.
Frequently asked questions
How much can you really save switching from gas to EV?
For an average US driver (12,000 miles/year, 25 MPG gas car, $3.45/gal gas, 3.5 mi/kWh EV, $0.16/kWh electricity), an EV saves about $1,108/year on fuel — roughly $11,080 over 10 years before accounting for maintenance savings, which typically add another $500/year.
Does this include maintenance savings?
No — this calculator focuses on fuel costs only. EVs typically save another $400–700/year on maintenance vs comparable ICE vehicles because there are no oil changes, fewer brake replacements (regenerative braking), and no spark plugs, fuel filters, or timing belts.
What about insurance — isn't it higher for EVs?
EV insurance averages 15–25% higher than ICE for comparable models, mostly because of expensive battery replacements after collisions. For a $1,500/year ICE policy, expect $1,725–1,875 for the EV equivalent. This typically erodes $200–400/year of the fuel savings.
Why does the calculator show such big variation by state?
Electricity rates range from $0.10/kWh (Washington) to $0.40+/kWh (Hawaii). Gas prices range from $2.80/gal (Mississippi) to $5+/gal (California). A driver in cheap-electricity / expensive-gas states saves dramatically more than one in expensive-electricity / cheap-gas states.
