I built an EV savings calculator with live government data after buying a Kia EV9 and spending two years confused, brutal feedback welcome!! - evchargesavings.com

The day I got my EV9, I spent two hours puzzling over why the included charger was adding 4 miles per hour. Turns out it was a Level 1 brick in a standard 120V outlet. Had to schedule an electrician the next week. That confusion — multiplied across every question I had about charging costs, connector types, and whether EVs actually pencil out in my state — is why I built this.

After I figured it out, four friends and coworkers bought EV9s partly based on my experience. I helped each one set up Level 2 charging and understand what their electricity rate meant for monthly costs. At that point a side project turned into a full resource.

What it is: evchargesavings.com — pick an EV, enter your ZIP, get estimated annual fuel savings using real EIA electricity and gas prices for your state.

What the calculator actually outputs:

  • A plain verdict: "Yes — switching makes financial sense" / "Borderline — incentives could tip it" / "Gas is cheaper for this driving pattern"
  • Annual fuel savings (and monthly, and 5-year)
  • Side-by-side fuel cost bars: your EV vs your current gas car
  • CO₂ saved per year
  • A break-even page — how many years of fuel savings pay back the EV price premium
  • Everything recalculates live as you move the annual miles and % charged at home sliders.
  • 100+ plain-English guides that go deeper on whatever the number surfaced — home charging setup, incentives, range anxiety, total cost of ownership
  • Daily EV news on policy and pricing changes that would actually move your savings estimate

What I tried to do differently:

  • Live data from EIA: electricity rates updated monthly, gas prices updated weekly — not hardcoded 2023 averages. A California driver at 30¢/kWh has completely different math than Wyoming at 11¢.
  • Written specifically for non-Tesla owners. That experience is genuinely different — charging networks, connector compatibility, road trip planning all work differently.
  • Explicit methodology page that shows the formulas and calls out what we don't model (maintenance, depreciation, incentives).

What I'm genuinely unsure about:

  • Is the calculator output trustworthy enough that someone would use the number to make an actual decision?
  • Does it feel like a useful tool or another affiliate SEO trap?
  • What's the first thing you'd change?

Will FSD transfer?

I found a used 2026 plaid mx with FSD included, but my question is will it transfer? How can I know if it’ll transfer?

Big Question for first time buyer

I need the help of everyone... i'm gonna get my first Tesla, and obviously I'm looking for a MX but the big question is... which year is the better (talking about the repair, battery assembly, parts).

The FSD is not a priority for me

Savings

Hi, I just bought a model X, I bought it because I liked it not the economics but something that has been stuck with me is that people mention how much one will save when they go EV. while shopping for insurance I found that insurance in my case was almost double even with clean record. car depreciates much faster. how does the number make sense?

TIA

Hesitant to take 5 hour trip in my X, Is there anything I should plan for?

As stated in the title I have a 5hr road trip coming up and as much as I use my X for a daily driver and love it, I'm a bit hesitant to take a longer trip. For the ones that are more seasoned with taking road trips in their MX is there anything I need to plan for or account for. Hopefully my question makes sense?

Used 2023 Model X

I’d appreciate some thoughts on purchasing a used 2023 Tesla Model X 7-seater with HW4.

Mileage: 69,000

Price: $56,000

I’m currently driving a paid-off 2018 Lexus RX350 and am considering trading it in.

Would love to hear any opinions or experiences - especially regarding reliability, high mileage, maintenance costs, and whether this seems like a reasonable deal overall.

I want you all to take a wild guess at how much this cost to repair 🤣

The only hint i’ll give is that it took a month to complete, and that thank GOD I wasn’t at fault.

Does anyone own one of these from a ruralish area? Falcon wing doors attention?

My wife is concerned about the attention the falcon wing doors would bring. We live in a rural area, as far as I know there isn't another model x in the area. How did the attention (if any) affect people here?

Salvage Title?

A dealership is selling a MX with 36k miles for $45k including taxes and registration. My question is will a salvage vehicle be marked or listed in some way under Tesla? Does the basic warranty and battery warranty still in effect? I never bought a salvage title before but I do know why it’s labeled that way. I’m communicating with the salesperson to find more information

Creaking noises at low speeds

My 2024 MXP makes these noises when I turn the wheel at low speeds or when sitting still. Anyone know what the cause is? Is it serviceable under warranty? Thank you!

2017 model x no working with V4 superchargers

Hi everyone, went on a road trip today and the trip planner had me stop at V4 supercharger. I plugged in and the indicator immediately switch from blue to white. I tried reconnecting several times with no luck. I moved through about 6 stalls with the same result then see other M3 and Ys plug in with no issues. I went to another V4 charger and had the same thing happened.

My 2017 x never got the CCS retrofit. Could this be the issue?

Roadtrip range discrepancy

I’m posting to see if anyone can help me reconcile a discrepancy I had in a recent roadtrip. I drove about 230 miles round-trip. 130 up to a charger, picked up my daughter from grandma, and 130 back home. Same day, same interstate, I took about a 10min charge and headed back home.

Details:

On my drive north, I left with 100% battery and arrived with 47%. (53% used). Computer said about 350Wh/mi

I charged from 47% up to 80% at the stop

On my drive south, l left with 80% battery and arrived back home with 12% (68% used). Computer said about 450Wh/mi

Conditions:
-Used FSD nearly 100% of the entire drive.
-Sunny, 80° day
-No elevation change
-Very little to no wind to speak of. However, I was traveling North/South, so an east/west wind no matter how small should impact the same.

I know identical drives will never be identical usage but 53% battery usage to 68% is nearly a 30% increase. Why?

Is the “top end” of the battery more efficient?

One last thing: When I left the charger to return home, it correctly projected arrival at 12%. I thought it was crazy and I “beat” that number comfortably. So, the car knows something I don’t. Just trying to figure out what that is.

TesserWatch Testers, a watch app for Tesla owners

"TesserWatch" a Legacy Tesla watch face and commands app in need of testers.

There already exist a few apps similar to this but I believe they are overpriced and over complicated. I made this because I wanted to expand the usability of older Tesla's like my 2017 Model S. With the app installed to your watch you are able to unlock your Tesla and start it with 1 tap. Newer Tesla's have Virtual Key which I plan to add but I do not have a vehicle to test with. If you want to try Virtual Key you can and please let me know what errors you encounter. Unlock all features with promo code "Playtest" in settings (scroll down).

Boosters for Refreshed 6-Seater

This has been discussed before but none of the past threads seem to provide anything definitive. We have a 5-year-old and are trying to find a backed booster that will work with the annoying Model X seats in either the 2nd or 3rd row. Nothing seems to work because of the shape of the seat and the headrests being static. There's always a gap. The only ones we've seen somewhat consistent feedback on are the Uppababy Alta V2 and the Diono Radian 3R. We just tried the Alta in the car at a store and there was a decent gap.

What is everyone doing for backed booster seats? Or are people just accepting there's a gap, which runs counter to the guidance from all the manufacturers?

2017 100d low speed clunk

There’s an audible clunk that happens only at speeds lower than 30km/h. It’s coming from center front when going over bumps/cracks/manhole covers. I’ve attached video. Control arms were replaced 1.5 years ago. Front heater and hepa filter replaced also 1.5 years ago at service center. Sounds like something loose bouncing around. Frunk is empty. Any ideas? Swapping tires next week and could have the shop look around if I knew what to point them at.
Thanks.

Sorry, in the video it’s the duller of the clunking noises, the two louder clunks are the suspension. It’s the duller clunks in between that drive me bananas. Yes, the road to my place needs repaving. Haha
