Quick answer
At representative Puget Sound rates (~$0.12/kWh), home charging delivers miles for roughly a third to a fifth of typical DC fast-charging prices — the install pays itself back in fuel savings, then keeps paying for the life of every EV you own. Public fast charging is the road-trip and no-garage layer, not the cheap layer. If you can install Level 2 at home, the math almost always says do it.
- Puget Sound residential electricity is cheap by national standards (~$0.12/kWh representative) — home charging here is among the best EV fuel deals in the country.
- Public DC fast charging typically prices several times higher per kWh, plus idle fees and session pricing — convenient, not cheap.
- A typical EV needs roughly 30 kWh per 100 miles: call it ~$3.60 at home versus commonly $12–$18 at corridor fast chargers for the same distance.
- Overnight Level 2 turns charging into a non-event: full every morning, off-peak-scheduled, no stops, no sessions.
- Condo and rental drivers can absolutely run public-only — it costs more per mile and rewards planning around Level 2 destination chargers.
At a glance
| Home Level 2 | Public Level 2 | Public DC fast | |
|---|---|---|---|
| Cost per 100 miles | ~$3.60 at ~$0.12/kWh | Varies — often free-to-moderate | Commonly $12–$18+ |
| Time for 200 miles | Overnight, asleep | Hours, while parked anyway | ~20–40 minutes, standing by |
| Role | The daily 95% | Opportunistic top-ups | Road trips and no-home-charging fallback |
| Upfront | $900–$4,500 install (canon) | $0 | $0 |
Per-mile math uses ~30 kWh/100 mi consumption and representative local rates; DOE's AFDC documents home charging as the lowest-cost, most-convenient primary strategy.
What does each option cost installed in the Seattle area?
The install ranges match our EV charger cost guide; the fuel math is what they buy. A commuter putting 12,000 miles a year on home electrons versus fast-charger electrons saves roughly a four-figure sum every few years — the circuit outlives several cars.
| Option | Typical installed range | What that covers |
|---|---|---|
| Home Level 2 install — standard | $900–$2,500 | 240V circuit, short clean run, panel with capacity. |
| Home Level 2 install — long run | $1,800–$4,500 | Detached parking or cross-house routing. |
| Public charging | $0 upfront | Pay per kWh/minute/session at several times the home rate for fast charging. |
What changes the price
- Your utility's rates and any EV/time-of-use plans — off-peak scheduling stretches the advantage further.
- Annual mileage: the more you drive, the faster the install pays back.
- Network pricing: fast-charge rates, session fees, and idle fees vary by network and time.
- Panel headroom: the usual install variable — load-managed chargers keep tight panels in play.
- Tacoma Power's charger incentive (up to $600) where applicable.

How do they work differently?
Why home miles cost so little
You're buying electricity at residential retail — no network markup, no session fees, no real estate and demand charges baked into the price. At roughly 30 kWh per 100 miles, a ~$0.12 kilowatt-hour puts fuel cost near 3–4 cents a mile, and off-peak plans push it lower. The car does its charging while you do your sleeping; the marginal effort is plugging in a cable.
Why public fast miles cost more
A DC fast station is a small industrial facility: 50–350+ kW of rectification hardware, commercial demand charges, land, maintenance, and network operations — all recovered through the per-kWh price, which is why it commonly runs several times residential rates. That's a fair price for 200 miles in half an hour on a road trip. As a daily fuel strategy, it's paying espresso-bar prices for tap water.
Pros and cons, honestly
Home charging
Pros
- Cheapest miles available — and schedulable for off-peak
- Full battery every morning, zero errands
- Gentler on the battery than routine fast charging
- One install serves every EV the household ever owns
Cons
- Upfront install cost (occasionally a panel conversation)
- Requires somewhere to park near your own wiring
Public charging
Pros
- Zero upfront cost
- Fast chargers make road trips practical
- Workplace/destination Level 2 can be cheap or free
- The only option for many condos and rentals
Cons
- Fast-charge pricing runs several times home rates
- Time spent waiting instead of sleeping
- Session availability, queues, and broken-station roulette
- Routine fast charging is harder on battery longevity
Which one should you choose?
Charge at home when
You can — that's genuinely the rule. If you own or can modify your parking situation, the Level 2 install converts EV fueling from an errand into a background process at the lowest available price. Even partial home charging (a Level 1 cord while you await the install) beats routing your life through charging stops.
Lean on public charging when
Home charging isn't installable — condo stalls without power, rentals with unwilling landlords, street parking — or you're on the highway, which is what DC fast infrastructure is for. Public-only EV ownership works; it just costs more per mile and rewards habit-building around workplace and destination Level 2 rather than daily fast-charge sessions.
Also consider: the condo/HOA conversation
Shared-parking buildings increasingly retrofit EV circuits — Washington law is broadly favorable to charging access, and load-managed multi-unit systems make it practical. If your HOA is the blocker, an electrician's load study and a managed-charging proposal often move the meeting. That's work we do for buildings, not just houses.
The verdict, by situation
Home Level 2
The default, by a wide margin
Cheapest miles, zero errands, one install amortized over every future EV. If it's installable, install it.
Public charging
The layer, not the plan
Essential for trips and for drivers without home parking — just budget honestly for per-mile costs several times home rates.
Hybrid habit
How most owners actually live
Home for the daily 95%, corridor fast charging for trips, opportunistic Level 2 where you park anyway. Boring and optimal.
Which Washington homes this fits
Single-family home, any commute
Level 2 install, full stop — the payback is fuel savings from month one and the convenience never expires.
Condo with a deeded stall, Seattle
Worth the HOA process: a load-managed circuit to your stall beats years of fast-charge premiums. We can support the proposal.
Apartment renter, street parking
Public-only works: anchor on workplace/destination Level 2, use fast charging as the exception, and revisit when housing changes.
High-mileage driver (rideshare, sales territory)
The math shouts: at 25,000+ miles a year, home-vs-fast-charge pricing differences compound into real money fast.

Common questions
How much cheaper is home charging, really?
At representative local rates (~$0.12/kWh) and ~30 kWh per 100 miles, home fuel runs about $3.60 per 100 miles. Corridor DC fast charging commonly lands at $12–$18 for the same distance once per-kWh pricing and fees are counted. Over a 12,000-mile year, that difference is roughly a thousand dollars — every year.
Does frequent fast charging hurt the battery?
Routine DC fast charging is measurably harder on battery longevity than AC charging — manufacturers manage it well, but their own guidance treats fast charging as the exception, not the diet. Overnight Level 2 is the gentlest way to own the pack.
Is the install worth it if I lease?
Usually yes — the circuit belongs to your house, not the car. It serves this lease, the next one, a second household EV, and it reads as 'EV-ready' at resale. The charger unit itself can move or be replaced; the wiring is the durable asset.
What if my panel can't handle a charger?
That's a load-calculation question, not a dead end. Load-managed chargers pace themselves around your service's real-time headroom, circuit-sharing devices piggyback on existing 240V circuits, and when none of that fits, the panel upgrade path (with WA HEAR support for income-eligible electrification) answers it permanently.
