Should You Buy an EV? A calculator to figure it out

Cost of battery maintenance seems to be a huge thing I never see mentioned here. I imagine EVs will depreciate much faster in that arena. My 15 year old Ford Focus still gets 30 mpg and still goes just as far on a full tank.

Teslas are now old enough that there's large-scale long-term battery degradation data available. They lose roughly 1%-2% of capacity per year (that's a linear approximation, actual degradation is steeper in the early years, tapers off later). So after 15 years you'd expect 70%-85% of the range left. Modern EVs have battery management systems that keep their temperature and other factors within the range that's gentle…

This doesn't take into account maintenance, which makes a huge difference ! My EV car (hyundai ioniq 2016) has now 100'000 km (62'000 mi) and I never once went to the garage for a service (except for tyres of course). Brake pads are still new, no oil change needed, etc.. Can't imagine how much it would've cost on a gas car

At 62k miles and 6 years, that would have probably been 6 to 10 oil and air filter changes, at $50 each would be $500. Brake pads would be $500. Miscellaneous other might be $500. Easily less than $1,500 for most decent brand cars. Excluding the common cost of tires, of course. How much extra did the Ioniq cost in 2016 over a Sonata or Acccord or Corolla or whatever the equivalent gas car would have been?

Mh, beside the issue of a spreadsheet itself [1] and the fact it's shared to the world [2] the real computation must be another: since crystal balls are out of service but luck is blind and bad luck sees very well... The right computation, witch happen to be pure logic NOT reducible to math, a thing soo many people forget is IMVHO "how likely is a diesel/gasoline shortage in the subsequent 1-8 years future?", "can I…

Spreadsheets are one of the most popular and widespread computing platforms out there. Excel is almost surely the single largest no-code/low-code install and monthly-active-users base. I don’t see spreadsheets as a failure nor evidence of poor state of computing or technical knowledge. If anything, I think they’re useful, practical, extensively used , and evidence that computing is working for people.

  =IF(A1 = 1, A2 * 3, MAX(A3, A4))

  (if (= A1 1) (* 3 A2) (max A3 A4))

Earlier quoted context omitted.

True, although there is also the advantage of convenience - all the time recovered from NOT having to go either fetch the materials and do teh maintainence yourself or bring the vehicle to the dealer/service station and wait. Count it as two hours each time, and it's easily 20 hours saved, more than half a work week that you are now free to do something else

Good point. Really depends what the difference in up front cost is. Anything more than $5k, and I think ICE is still prudent if you are not driving at least 15k miles per year. Plus, ICE are time tested. The new EVs coming out have a lot of unknown risks and reputation to still build up. I do not mind letting others beta test.
