After 10,000 miles here’s how much it really costs to own & drive a Tesla Model 3 after factoring in all the details.
These numbers are all based off my personal experience so it’s not going to be the same for everyone but at least it will give you an idea of the costs and how much a difference it is driving a Tesla compared to an internal combustion engine vehicle. I’m going to compare my Model 3 acquisition to what it would be like if I kept driving my 2007 Pontiac G6.
The total cost of my Long Range Tesla Model 3 was $56,000. I also had to pay $3,422 for taxes. I am getting the full $7,500 tax credit but my car insurance increased by $500/year so assuming I keep my Model 3 for at least 5 years that brings it to $54,422. However we also have to calculate the cost of installing a home charging outlet. This cost heavily depends on your particular location and how difficult the install is. My NEMA 14-50 outlet cost $900 for a professional electrician to install, which is on the expensive side because my box was the furthest possible distance from my garage so they had to run cable underground which increased the price.
That brings it to a grand total of $55,322 upfront cost for my First Production Long Range Tesla Model 3, assuming I keep it for at least 5 years. How much does it cost to charge & drive a Model 3 compared to buying gas? My Model 3 is at 10,400 lifetime miles and it’s averaging 233 Wh/mile.
So far I’ve only spent $20.29 on four Supercharging sessions, and that resulted in approximately 700 miles of range which means the other 9,700 miles traveled were from charging at home in my garage. To find out how much it’s cost to travel those 9700 miles we need to calculate my electricity rate along with the Model 3’s charging efficiency. My off-peak electricity rate when I charge my car at home is $0.06882 per kWh.
However, 100% of the electricity doesn’t make it into the car’s battery when charging at home. This is true for all electric cars. Edmund’s is doing a long-term test drive of the Model 3 and they’re measuring the average wall-to-wheels efficiency. So far from their tests they’ve seen an 83.3% charging efficiency (meaning only about 83% of the electricity makes it from the charging cable into the car battery). If we also account for the amount of battery that depletes as the Model 3 is just sitting somewhere not plugged in (I’ll make a guesstimate and say 3% is a fair assumption for vampire drain), that brings us to 80% total charging efficiency.
So 9,700 miles at an average of 233 Wh/mile with an electricity rate of $0.06882 per kWh with an 80% charging efficiency equals $186.65. And if we add the $20.29 I’ve spent on Supercharging that comes to a grand total of $206.94 spent to travel 10,400 miles in my Model 3. If you compare that to my 6-cylinder automatic transmission 2007 Pontiac G6 which averages 21 miles per gallon and using the current average cost of gas in my area which is $2.77 per gallon, the total cost to travel 10,400 miles would be $1,371.81.
That means I’ve saved almost $1,200 over 10,400 miles or maybe it’s better to say that’s $1,200 I’ve stopped having to give to gas stations since getting my Model 3. And I’m not driving a car that puts out any emissions which feels great. Also keep in mind there are free apps like PlugShare and ChargePoint that show you locations of thousands of public charging stations, most of which are completely free for anyone to charge their electric car which is something that just doesn’t exist with gas stations.
Also I’ve saved so much time from not having to stop at gas stations during my normal weekly driving. It takes me 5 seconds to plug in my Model 3 in my garage. When I drove a gas car I had to get gas at least once or twice per week, and each stop took around 5 minutes. So over the course of a year that’s a huge amount of time saved from not having to stop at gas stations. We could also get into the money saved from oil changes and maintenance but that’s another story. So far I’ve paid absolutely $0 in maintenance for my Model 3 so hopefully that continues.
Bottom Line: The Tesla Model 3 been a fantastic car after 10,000 miles and it’s still just as much fun as the day I got it. I hope you enjoyed this detailed look into how much owning and driving a Tesla Model 3 actually costs.
