What it does

EV Power Bill, in four moves.

Click any card to jump to its deep dive below.

Who it's for

Built for these decisions.

If any of these are your question, this is the tool.

Shopping a Model 3 vs a Bolt

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.

Already own an EV

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.

Long commute, mostly highway

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.

Road trip planner

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.

The problem

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.

What you'd get

Four pieces, one tool.

Each piece ships in the first build for waitlist members. SaaS upgrades layer on top.

01 ยท feature

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.

Scenario picker
02 ยท feature

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.

Drawdown chart
year 22$1.0My0y40
03 ยท feature

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.

Inflation drift

Cliff edge

04 ยท feature

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.

Why paid

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.

โœ—National average only. No ZIP, no time-of-use, no Supercharger blend, no per-model efficiency curve.
Their pricing
โœ—Charger-finder app with a basic cost field. No ownership projection, no saved scenarios, no winter or highway mode.
Their pricing
โœ—Marketing funnel, not a planning tool. Picks favorable assumptions to make the EV look cheaper than it is.
Their pricing
Spreadsheet you build yourself
โœ—Manual rate lookup, manual model lookup, breaks the moment your utility files a new tariff. Useless for comparing two cars on the same ZIP.

What's not included

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.

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.

FAQ

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.
