// Free Tesla Savings Tool
Find out exactly how much switching to a Tesla saves you on fuel every year — and when it breaks even. This calculator goes beyond the basics: see your 10-year cumulative savings with gas price inflation, the break-even year with and without the $7,500 EV credit, your cost per mile vs a gas car, maintenance savings, and CO₂ reduced. Enter your numbers and see the real math.

Common questions about Tesla fuel savings, cost per mile, break-even timeline, and how this calculator works.
It depends on how much you drive and what car you're replacing. A typical US driver doing 12,000 miles per year in a 28 MPG gas car at $3.65/gallon spends about $1,564/year on gas. A Tesla Model Y LR driving the same miles at home electricity rates (14¢/kWh) costs about $480/year to charge — a savings of roughly $1,084/year on fuel alone. Add ~$800/year in maintenance savings (no oil changes, fewer brake jobs) and you're saving over $1,800/year total. This calculator shows your specific numbers based on your car, mileage, and local electricity rate.
MPGe (Miles Per Gallon equivalent) converts electric efficiency into gas-car terms. The EPA uses 33.7 kWh = 1 gallon of gas. Tesla Model Y LR gets about 134 MPGe — meaning it uses the same energy as 1 gallon of gas to travel 134 miles, vs. 28 miles in a typical gas car. That's 4.8× more efficient. In practical driving at 14¢/kWh home electricity, Tesla's "effective gas price" equivalent is about $0.94/gallon — no matter what gas costs at the pump. This is why Tesla owners feel insulated from gas price spikes.
At US average electricity rates (14¢/kWh), a Tesla Model Y LR costs about 4.0¢ per mile to charge at home. At Supercharger rates (22¢/kWh), that rises to about 6.3¢ per mile. Compare that to a 28 MPG gas car at $3.65/gallon: 13.0¢ per mile. Most Tesla drivers save 7–9¢ per mile vs. their previous gas car. On 12,000 miles per year, that's $840–$1,080/year in fuel savings. High-mileage drivers saving 9¢/mile over 20,000 miles save $1,800/year on fuel alone.
Break-even depends on the price difference between the Tesla and the gas car you'd otherwise buy, and your annual savings. Example: Model Y LR ($49,990) vs. a Honda CR-V ($35,000) = $14,990 price premium. After the $7,500 federal tax credit, the effective premium is $7,490. At $1,800/year in combined fuel + maintenance savings, the break-even is about 4.2 years. Without the credit: about 8.3 years. The break-even tab in this calculator shows your exact year based on your inputs — including gas price escalation, which accelerates break-even as gas prices rise over time.
At the US average home rate of 14¢/kWh, charging a Tesla Model Y LR from 20% to 80% (useful range: ~168 miles) costs about $8.80 at home. The same charge at a Supercharger at 22¢/kWh costs about $13.80. Most Tesla owners charge primarily at home (80–90% of miles) and only Supercharge on road trips. The calculator lets you set your Supercharger percentage to blend the two rates accurately. As a rule of thumb: home charging is always cheaper — install a Level 2 home charger if you can.
Yes — even in California where electricity averages 28¢/kWh (and peaks above 50¢/kWh on TOU plans), a Tesla still saves money vs. gas. At 28¢/kWh, the Model Y LR costs about 8¢/mile — vs. 15–18¢/mile for a California driver paying $5–6/gallon. Annual fuel savings are typically $1,200–$2,000/year in California even at high electricity rates. The key is charging during off-peak hours (usually 9 PM–7 AM) on TOU plans, which can reduce your effective rate to 14–20¢/kWh — significantly improving the savings picture.
Significantly — and this is where Tesla ownership becomes a hedge. Every $0.50 increase in gas prices saves a Tesla driver an additional $214/year (at 12,000 miles, 28 MPG). At $5/gallon gas, a 28 MPG car costs $2,143/year in fuel — vs. $480/year for a Model Y LR charged at home. That's a $1,663/year fuel savings. This calculator includes a gas price escalation input (default: 3%/yr) that compounds savings over 10 years — showing why Tesla's break-even accelerates faster than most people expect.
Teslas have no oil changes ($100–$200/yr), no transmission service, no spark plugs, and significantly less brake wear (regenerative braking does most of the stopping). Typical Tesla maintenance savings vs. a comparably priced gas car: $700–$1,200/year. Main Tesla recurring costs: tire rotations (~$50/yr), windshield wiper replacements (~$30/yr), annual inspection in states that require it (~$30), and occasional cabin air filter ($30 DIY). Unexpected costs: tire replacement (Teslas are heavier and use performance tires — ~$800–$1,200 per set, slightly more often than avg).
This calculator uses the EPA's US average grid emissions factor of 0.386 kg CO₂ per kWh. A Tesla Model Y LR driving 12,000 miles at 3.5 mi/kWh uses 3,429 kWh — producing about 2,930 lbs (1,330 kg) of CO₂ equivalents from electricity generation. A 28 MPG gas car driving the same miles produces about 7,895 lbs (3,581 kg) of CO₂ at the tailpipe. That's a reduction of roughly 4,965 lbs (2,251 kg) of CO₂ per year — about the same as planting 60 trees. In states like California, Washington, or New York with cleaner electricity grids, the CO₂ reduction is even larger.
The $7,500 federal EV tax credit doesn't directly affect your gas savings — it reduces your effective purchase price, which changes your break-even calculation. If you're comparing a $49,990 Tesla to a $35,000 gas car, the price premium is $14,990. After the $7,500 credit, your effective premium is only $7,490 — cutting your break-even time roughly in half. Starting January 2024, the credit can also be applied as a point-of-sale discount at the dealer, meaning you get the benefit immediately rather than waiting for your tax return. Income limits apply: $150K (single) / $300K (married) for new EVs.
