EV Power Bill, in four moves.
Click any card to jump to its deep dive below.
Built for these decisions.
If any of these are your question, this is the tool.
Which one actually costs less to charge in my ZIP?
โ Side by side. Two models, your ZIP, your driving mix. Real five-year electricity bill on both.
Should I switch to my utility's EV time-of-use plan?
โ Compare your current rate against the EV plan with your charge timing. See the annual difference in dollars.
Will winter highway driving wreck my range and my bill?
โ Highway-and-winter mode shows the realistic kWh per mile, not the city loop optimist number.
What does 2,000 miles of Supercharger-only charging actually cost?
โ Blend home and DC fast at any ratio. See exactly how road trips lift the monthly bill.
Every EV cost calculator uses one fake number. Yours costs a real one.
Every EV charging cost calculator out there uses one national average rate. That number is fiction. Your actual bill depends on your ZIP code, your utility's time-of-use plan, the EV model's efficiency under your driving pattern, and whether you charge at home or use DC fast chargers on road trips. The dealer's $0.04 per mile sticker turns into $0.11 the moment you plug into a Supercharger. A $40K car decision deserves a real number, not a marketing average.
Four pieces, one tool.
Each piece ships in the first build for waitlist members. SaaS upgrades layer on top.
Real utility rates by ZIP
Type your ZIP. We pull your residential plan, peak and off-peak windows, seasonal tiers, and any EV-specific rate plan your utility offers. National-average calculators miss this and they are off by 40 to 60 percent in California, Texas, and the Northeast.
Real-world efficiency, not EPA
200+ EVs with miles per kWh measured across city, highway, and winter cold. EPA numbers are a single test cycle. Owners report 25 to 40 percent worse on highway in February. We use the owner data.
Home and Supercharger blend
Set your charge mix. 90 percent home overnight, 10 percent DC fast on weekends, or any ratio. We blend the rates and show the true monthly bill, not just the cheap home number.
Saved EVs and side-by-side compare
Save up to 5 EVs you are considering. Compare two at a time on the same ZIP and same driving pattern. Export the full 5-year bill projection as a PDF for the dealer or your spouse. SaaS upgrade tier.

Today's tools don't do this.
An EV decision based on a fake national rate can be off by $1,500 to $4,000 over five years. A 1-hour fee-only financial advisor is $200 to $500 just for the conversation. One bad assumption costs more than this tool ever will.
ZIP-aware rate lookup across 1,400+ US utilities. Per-model real-world efficiency for 200+ EVs. Home and DC fast charge blend. 5-year ownership bill projection.
Saved EVs, side-by-side compare on identical inputs, PDF export. Quarterly rate refresh tracker. SaaS tier ($19/mo).
Tax credit advice, dealer financing math, or insurance quotes. This tool answers one question: what will charging actually cost me. For tax and finance, see a CPA.
Which price would get you on the waitlist?
No charge today. The click tells me which tier is real demand. Early access price โ launch price.

Solo builder ยท Choppy Toast
This page is a quick vibe-coded probe to test demand and gather feature requests. The actual product, when it ships, will be a polished, hand-built tool, not this scaffold.
For a sense of what "polished and shipped" looks like, here's another product I built: relly.permissionlabs.com.
Honest answers.
Then I wait. The waitlist stays live, no expiry, no archive. The faster you tell one EV-shopping friend, the faster it ships. That is the whole engine.
