Hello,
I have had my Model-3 past one year and enjoying every single time I sit in it (at times I just try to "find" reasons just so I can drive it).
But, every time I plug it to charge, this question comes in to my mind, in the long run "Are we REALLY REALLY SAVING MONEY owning a Tesla??"
Because, between Sentry mode, cabin temperature maintenance... and other miles-sapping activities that we might just not be aware of, my Model-3 tends to lose around 3-5 miles per 24 hours... give or take a couple of miles... WHETHER I DRIVE MY CAR OR NOT. That's serious loss of miles/charge, just with the car sitting out there in my garage.
What are your (unbiased) thoughts?
I joke with my ICE car-owning husband about what a waste of time it is going to the gas stations "just LOOK at that line!" hehe
What's your rate?
Even at the peak rate we have here, if your on a TOU plan, is $0.42/kWh. From what I've seen a Model 3 Performance uses about 360wh/mile. So even if I charged 100% at peak times my 6,000 miles would still be $200 cheaper than I paid for gas.
In reality I'm not on the TOU plan because I'm home all day and it would be WAY more expensive to run my A/C in the summer. So I'm on the flat rate plan which is only $0.092/kWh 24/7.
If I were on the TOU plan and charged only on off peak hours it would be even cheaper as the special EV rate for off peak is only $0.052/kwh.
So driving the car VERY conservatively you get an equivalent to a 30 mpg ICE. Basically no fuel savings around here
Now if you can get Electricity at half my rate or better then savings start to be real. And then your ROI might be 5-7 years
Your answer: Mommy is going to commandeer the car once she gets to drive it and I will continue to locate the cheep gas for the Yugo that I will drive instead. When you are stable enough, baby doll, to move out at 40 (hopefully sooner), maybe then I can afford another Tesla. Oh wait! I still am on the hook for your college and future wedding...As my daughter said to me after I told her I bought a Tesla: "but dad, what about your hobby of trying to find the cheapest gas station?"
I too don't really get the question. Of course owning a Tesla, like any car costs more than not owning a car; so you must mean compared to something else - but nobody can give you a reasonable answer unless you tell us what you are comparing it to (and how much you drive).
If you are just worried about the cost of Sentry and Cabin Overheat, you can turn them off.
Nice referenceI didn't buy the car to save money, I bought the car to keep from going full Falling Down in traffic.
Since I bought a $60k (plus government greed levy) car and had my insurance cost go up dramatically afterwards, though, it's a net negative financially.
I'm sorry you have to pay so much for electricity. That does negate a lot (or all) of the savings.
Here in Texas, average electricity rates are between 9 and 11 cents per kWh. There are some TOU plans available where 9PM to 6AM power is free.
At $0.11/kWh, a performance Model 3 costs $2,600 to drive 75,000 miles, or a RWD costs $1,980 to drive 75,000 miles (5 years). An ICE that gets 25 MPG at $2.50/gal costs about $7,500 to drive 75,000 miles. That's $4,800 savings in the Performance, or $5,500 savings in the RWD.
It's a full $7,500 savings on my TOU plan.
Of course, this is fuel savings only, total cost of ownership has many other factors in it.
Your Model 3 Performance at $0.42 (this does not include charging overhead)
6000 miles * 0.360 Kwh / mile = 2160 Kwh
2160 Kwh * $0.42 Kwh = $907
Prius @ 50 mpg (New England Fuel Prices)
6000 miles / 50 mpg = 120 gallons
120 gallons * $2.30 gallon = $267
Audi A4-ish @ 30 mpg (New England Fuel Prices)
6000 miles / 30 mpg = 200 gallons
200 gallons * $2.30 gallon = $460
That was with what gas cost me locally which is very cheap.
Let's try worst gas prices and the not so efficient 30 mpg car (most cars are better than that today)
200 gallons * $4.00 gallon = $800
Now use my Rate $0.26 / kWh on your Model 3 Performance
6000 miles * 0.360 Kwh / mile = 2160 Kwh
2160 Kwh * $0.25 Kwh = $540 (Still more expensive than a 30 mpg using local gas prices).
Now, 0.360 kWh / mile is ridiculously awful !! My year round average (on my Performance Stealth on 19") is ~0.250 kWh/mi
And lets include charging overhead this time (I'll use 90% efficient charging).
0.250 kWh / 0.90 = 0.277 kWh/mi
6000 miles * 0.277 Kwh / mile = 1666 Kwh
1666 Kwh * $0.26 Kwh = $432 (very close to a 30 mpg car in New England)
So driving the car VERY conservatively you get an equivalent to a 30 mpg ICE. Basically no fuel savings around here
Now if you can get Electricity at half my rate or better then savings start to be real. And then your ROI might be 5-7 years
