EV Charging Membership: Break-Even kWh by Network

Electrify America's pricing page does not publish a price. I pulled it on 28 September 2026, stripped the markup, and searched the rendered text for dollar amounts. One hit: a temporary authorization hold, placed on your card in $20 increments. The per-kWh rate is not on the page. Neither is the Pass+ membership fee, which is the single number a break-even calculation turns on.

No single company is being coy here. The break-even question — how much do I have to charge before a monthly fee pays for itself — has an answer that fits on one line of arithmetic, and the industry as a whole keeps both inputs to that line inside an app you have to install and sign into.

So this is the arithmetic, the places each network does and does not put the numbers, and the two situations where a plan that looks obviously worth it stops being worth it.

The formula changes shape with what the plan discounts

There is no single break-even formula, because there are three different things a paid plan can do for you, and each one produces a break-even in a different unit.

It can set a lower per-kWh rate. Then your answer is in kilowatt-hours:

break-even kWh = monthly fee ÷ (non-member $/kWh − member $/kWh)

It can take a percentage off. Then your answer is in dollars of spending, and only becomes kWh once you know the rate:

break-even spend = monthly fee ÷ discount fraction

It can waive a fixed per-session fee. Then your answer is in sessions, and kilowatt-hours have nothing to do with it:

break-even sessions = monthly fee ÷ per-session fee waived

Real plans mix the second and third. Which means the honest version, the one to actually use, has two terms on the savings side:

monthly saving = (sessions × session fee waived) + (kWh × per-kWh gap)

Subscribe when that total clears the monthly fee. Rearranged for the number most people want:

kWh needed = (monthly fee − sessions × session fee waived) ÷ per-kWh gap

And note what happens when the first bracket goes negative. If the waived session fees alone already exceed the monthly fee, the plan pays off at zero kilowatt-hours and the per-kWh discount is gravy. That case is common and almost nobody checks for it, because the marketing is written in percentages and percentages hide fixed fees.

What the three biggest networks actually publish

Here is what is on the public web, as read on 28 September 2026.

EVgo's pricing page is the most forthcoming of the three. It lists EVgo PlusMax at $12.99/month with "Save up to 30% per month" and no session fees, EVgo Plus at $6.99/month with "Save up to 15% per month" and no session fees, and Pay As You Go at $0/month with $0.99 session fees. A separate footnote states that a $2.99 transaction fee applies for all sessions initiated by credit card. The page's own small print is the important part: "Actual savings vary by time of use, location, frequency, and length of charging session. Savings are calculated as compared to EVgo's standard rates with session fees. Station specific pricing by plan is available within the EVgo app." It also notes "Pricing shown is effective October 10, 2022" and that all rates vary by region, with Level 2 at $0.28/kWh in select locations.

Read that footnote twice. The advertised 15 and 30 percent are measured against standard rates including session fees, so part of the headline percentage is the disappearance of a fixed $0.99, not a cheaper electron. For a small session that fixed fee is a large share of the bill; for a 50 kWh session it is rounding error. One advertised percentage, two completely different break-evens.

Electrify America's pricing page says "Save about 25% on charging when you sign up to be a Pass+ member via the Electrify America mobile app" and then hands the actual numbers off to hardware: refer to the charger screen, it says, for the most up-to-date information on pricing, power levels and idle fees. The fee itself lives in the app. The Subscription Agreement (effective 10 April 2019, read 28 September 2026) confirms this in writing: you agree that Electrify America can charge "the monthly fee specified under 'Plan Details' above," and you receive discounted pricing "in the amounts set forth under 'Plan Details' for each region. Discounts may vary depending on the region." Two further clauses matter for anyone timing a subscription. Fees already paid for the current month are non-refundable, and there is no minimum purchase obligation, so the discount applies from your first kWh — there is no threshold to cross, only a break-even to beat.

Tesla I could not verify, and the reason is worth recording rather than glossing. I tried four separate routes at its Supercharger support pages on 28 September 2026 — curl with a browser user agent, headless Chrome, the WebFetch tool, and a text-extraction proxy — and every one came back HTTP 403. That is a bot block, not evidence about Tesla's plan. I am not going to put a figure in a table because a search snippet offered me one; two of the snippets I read while researching this piece gave EVgo numbers that the network's own page contradicts. If you drive a non-Tesla and want Tesla's membership fee, the Tesla app is the source, and whatever it shows you is worth dating in a note before you rely on it.

Two other names come up in this question. I found no network-wide paid driver membership on ChargePoint's driver pages, and no prices either — several of the pricing paths I tried returned 404 on the day I looked. That is consistent with pricing being set site by site rather than by the network, but I could not confirm that from ChargePoint's own pages, and "I did not find one" is not "there is none." Ionna is the one network here that answers the question outright, in the other direction: its home page advertises DC fast charging with "No app, No subscriptions and Plug & Charge ready." That is a claim about the absence of a plan rather than a price — a different kind of fact, and unusually for this question, one a network puts in public where you can read it.

EVgo's session fees give you a break-even you can calculate today

Because EVgo publishes its fixed fees, you can finish part of this calculation without installing anything. This is the zero-kWh case from the formula above, and unlike the illustrations further down this page, every figure in the next table is one EVgo printed on its own pricing page as read on 28 September 2026 — subject to the caveats that page attaches to itself, namely that pricing shown is effective October 10, 2022 and that all rates vary by region and may change at any time.

The arithmetic is $6.99 ÷ $0.99 = 7.06, rounded up to the first whole session that clears it. Nothing in that table depends on how many kilowatt-hours you take, where you live, or what the energy costs. It says: if you charge eight times a month on EVgo, Plus has already paid for itself in session fees alone, and every kilowatt-hour of discount after that is profit.

The bottom two rows are the ones that surprise people. If your habit is tapping a credit card at the machine rather than running the app, you are inside a $2.99 fee structure, and three sessions a month covers the Plus subscription outright. Whether the $2.99 stacks with or replaces the $0.99 is not something I could resolve from the page, so treat the station screen as authoritative.

What the table cannot tell you is the second term — the per-kWh gap — because EVgo publishes member rates only in the app. Open the app, pick the station you actually use, and read the rate under two plans. That difference, times your monthly kWh, is what you add to the fixed saving.

A percentage discount is a multiplier on your bill, not on your kWh

When a plan is sold as a percentage rather than a rate, the break-even collapses to something you can memorize. Divide one by the discount and you get the multiple of the monthly fee you must spend at non-member prices.

So a 25 percent plan at a hypothetical $7 a month needs $28 of charging at guest prices before it earns its keep. Turning that into energy takes one more division. At an illustrative guest rate of $0.56/kWh — my own placeholder to show the shape, not any network's current price — that is $28 ÷ $0.56 = 50 kWh a month, somewhere around one and a half DC fast sessions.

That is a low bar, and it is why these plans are usually worth it for anyone who fast charges at all regularly. But run the same arithmetic against a cheaper rate — also invented — and it moves. At $0.36/kWh the same $28 becomes 78 kWh. The break-even in kilowatt-hours gets harder as electricity gets cheaper, which runs backwards from how it feels and is exactly why a break-even figure copied off a comparison blog is worthless in your own zip code.

One more trap in the percentage framing. If the advertised percentage was calculated against a baseline that includes fixed fees — the way EVgo's footnote says its figures were — then applying that percentage to your energy spending overstates the saving, because you have already counted the fixed-fee part separately. Use the two rates from the app. Do not use the percentage from the billboard.

Per-minute stations move the break-even every time it gets cold

Everything above assumed the station bills you per kilowatt-hour. Where it bills per minute, a plan expressed in per-kWh terms has nothing to grip, and a plan expressed as a discount on the per-minute rate has a break-even measured in minutes.

Minutes are not kilowatt-hours, and the exchange rate between them is set by your battery rather than by the network. The same plan, the same station, the same driver: a warm pack accepting 150 kW converts a discounted minute into a lot of energy, and a cold-soaked pack accepting 30 kW converts the same discounted minute into a fifth as much. Your break-even in useful energy therefore gets worse in January, worse above 80 percent state of charge, and worse if your car's peak acceptance is modest to begin with. Battery preconditioning is the one variable you control here, and on a per-minute plan it converts straight into money rather than merely into saved time.

Why per-minute billing still exists at all, and which states pushed networks into it, is its own story — the four line items on a charging receipt covers the utility-law history and the federal rule that now forces a $/kWh display at federally funded sites. For break-even purposes the practical rule is short: if the stations you use bill by the minute, calculate in minutes, and recalculate in winter.

The fees a discount usually does not touch

A bill is not one number, and a discount rarely applies to all of it. Before you divide anything, find out which components the plan actually reduces.

• Energy is almost always discounted. It is the thing the plan is actually selling, and it should be the only line sitting in your denominator.
• Session or connection fee. Sometimes waived outright, as in EVgo's Plus and PlusMax. When it is waived, it belongs in the fixed-saving term, not the percentage.
• Idle or congestion fee. Charged per minute after your session ends while you still occupy the connector. On none of the pages I read did a network say that a membership reduces one.
• Sales tax applies to the discounted subtotal, in the states that tax charging at all. It follows the discount downward but is not itself a saving.
• Parking belongs to the property owner rather than to the network, so no charging plan touches it.

The idle fee deserves a specific warning, because it corrupts the calculation in a way that feels like good news. An idle fee inflates your monthly total without being discounted, so if you work out your savings as a percentage of your whole bill, the arithmetic quietly credits the plan for money it never saved you. Do the division against the energy line only. And since an idle fee lands on members and guests at exactly the same rate, no plan sold on any of these pages can reduce it by a cent. It is the one line above that a monthly payment cannot improve at all.

Free charging that came with the car makes the membership a pure loss

If your car came with a charging promotion, a paid membership during that window is money for nothing, and the fine print says so plainly. Electrify America's pricing page (read 28 September 2026) states that Premium Offer plans including complimentary charging are not affected by its pricing changes, and that once your plan expires or you exceed your plan benefits for a session, "the remainder of your charging will automatically be billed at our Pass plan pricing." Pass is the tier with no monthly fee — the Subscription Agreement calls it "a non-subscription Electrify America Pass plan" where it explains cancelling — so the overflow lands at undiscounted rates unless you have separately enrolled in Pass+.

Three dates decide this, and none of them are on the network's website either:

1. When the bundled credit expires. Usually in the delivery paperwork or the automaker's app, and frequently measured from the delivery date rather than the model year.
2. What the credit actually covers — a number of kWh, a number of sessions, a period of time, or a dollar value, each of which runs out differently.
3. What happens to the overage. Per the language above, Pass pricing. That is the number your break-even should be computed against for any charging beyond the credit.

Put the expiry date in a calendar with the subscription decision attached to it. A subscription fee is charged on a monthly cycle and, at least under Electrify America's agreement, is non-refundable for the month already paid, so the cost of subscribing a few months early is real and small and entirely avoidable.

What the federal rule means for anyone selling you a membership

There is a floor under this whole question, and it is easy to miss while you are comparing plans. Before you conclude that a network has you cornered, read the rule that binds some of its sites. I pulled 23 CFR 680.106 from the eCFR versioner API on 28 September 2026, against the Title 23 issue dated 23 September 2026. Subsection (f) covers payment methods at stations built with the federal funding the part reaches, and two of its four clauses are the relevant ones: such a station must "not require a membership for use," and must "not delay, limit, or curtail power flow to vehicles on the basis of payment method or membership."

Read together, those two lines mean a membership at these sites can only ever be a discount. It cannot be an access key, and it cannot be a speed key. If you plug in as a guest and the session crawls, that is worth a complaint rather than a subscription.

There is also a records route most drivers never hear about. § 680.106(a) requires States or other direct recipients to "ensure public transparency for how the price will be determined and set for EV charging" and to make available for public review, among other items, "any information describing how prices for EV charging are to be set under the proposed contract, in accordance with State law." The awardee and the proposed contract are on that list too. Which means that for federally funded sites, the pricing logic your app refuses to explain may exist as a public record at your state DOT.

The catch is the one that limits every clause in the part: these duties ride on the grant, and the machine in front of you does not say whether this particular site took one. Where the rule does reach, it settles the question cleanly — access and undiminished power cost a guest nothing, so the only thing a plan can sell you at that site is the discount, which is precisely the number the arithmetic above is built to test. Where it does not reach, you are back to reading the app.

Five numbers and a date

Everything above reduces to a note you can write in about four minutes, sitting on a couch with the app open, for the one station where you do most of your charging:

1. The non-member per-kWh rate at that station, and whether it is per kWh or per minute.
2. The member per-kWh rate under each paid plan at that same station.
3. Any per-session fee on the free tier, and whether the paid plan waives it.
4. The monthly fee. EVgo prints this one on its website; on Electrify America the app screen was the only place I could find it at all.
5. Your sessions per month and kWh per month — both are in the app's own charging history, which is a better record of your habits than your estimate of them.

Then run the two-term version: sessions times the waived session fee, plus kWh times the rate gap, against the monthly fee. And compare the whole result to what the same kilowatt-hours would have cost at home, because for most drivers most months, the largest available saving is not a subscription at all but an overnight rate on the right utility tariff.

Write today's date next to those five numbers. EVgo's page still carries an effective date of October 10, 2022 and warns that rates vary by region and change at any time; Electrify America's agreement reserves regional variation outright. A break-even figure without a date beside it is a guess wearing a decimal point.
