Short answer: an idle fee is a per-minute charge for staying plugged in after your session ends. Tesla has charged $0.50 per minute (doubling to $1.00 at a full station) after a 5-minute grace period, and only when the site is busy; Tesla says rates vary by site and can change, so treat those figures as typical rather than guaranteed. Electrify America charges $0.40 per minute after 10 minutes. EVgo, ChargePoint, and Blink set it station by station, so check the app before you plug in.
You plug in, walk into the store, and lose track of time. Twenty minutes later your car finished charging fifteen minutes ago, it is still sitting in the stall, and a text just landed telling you idle fees are running. At a busy Tesla Supercharger, those ten billable minutes can cost several dollars, and as much as $10 at the highest commonly reported rate. This is not a rare mistake. It is the single most common way first-time public charging users get an unpleasant surprise, and the rules differ enough by network that "just don't overstay" is not specific enough advice to actually follow.
What an idle fee is, in plain terms
An idle fee is a per-minute charge that starts once your car stops actively charging but stays plugged in. Networks bill it separately from the electricity itself, and the logic is simple: a stall you are not using is a stall someone else cannot use. The fee is designed to hurt enough that you move your car promptly, not to generate meaningful revenue on its own.
The trap is that "stops actively charging" is not always obvious from inside the car. Charging tapers dramatically once a battery passes roughly 80%, so a session that shows "still charging" on your dash can be adding only a trickle of range while the clock the network cares about has already started.
What each major network actually charges
Idle fee policy is not standardized across networks, and it is not always even standardized within one network. Here is what each one does as of October 2026.
| Network | Grace period | Idle fee | When it applies |
|---|
| Tesla Supercharger | 5 minutes after charging ends | Commonly reported as $0.50/min when the station is 50%+ occupied, doubling to $1.00/min at 100% occupied; Tesla says the rate varies by location | Only when the station is busy; an empty or quiet site charges nothing even if you linger. Tesla also runs a separate congestion fee at some busy sites that depends on your battery level (reported around 80%), so check the app |
| Electrify America | 10 minutes after the session ends | $0.40/min | Applies network-wide. One wrinkle: at select metro-area stations in the company's Congestion Reduction Effort, the charger automatically ends the session once your battery reaches 85% state of charge, and the 10-minute clock starts right then, earlier than a driver planning to charge to 100% would expect. Those stations are flagged with an "85% Limit" banner in the app |
| EVgo | Varies by station | Varies by station | EVgo does not publish a single network-wide idle fee; check the specific station's terms in the app before you plug in |
| ChargePoint | Varies by station | Varies by station, set by the property owner, not ChargePoint | ChargePoint is a hosted network: individual businesses and property owners set (or skip) what ChargePoint calls an Overstay Rate, a time-based charge that starts after charging completes and a grace period passes, shown in the app per station. Separately, since March 2026 ChargePoint bills its own flat per-session Service Fee ($0.25 Level 2 / $0.49 DC fast for account holders; $0.49 / $0.99 for guests paying by card), unrelated to idling and billed whether or not you overstay |
| Blink | Varies by station | Varies by station | Mixed network of Blink-owned and host-owned stations; hosts choose their own pricing and no uniform company-wide idle policy exists, so the app is the source of truth. Blink does bill a flat $0.49 access fee per session at paid stations, which, like ChargePoint's Service Fee, applies whether or not you overstay |
The pattern worth noticing: the two big highway networks, Tesla and Electrify America, have a real, predictable, published rate. The others push the decision down to whoever owns the specific charger, which means the straight answer to "what will I be charged if I overstay at this EVgo station" is "open the app and look," not a number this article or any other can promise you in advance.
Tesla's occupancy-based structure is the one most drivers get wrong. Because the fee has historically only kicked in once a station is at least half full, you can genuinely sit at an empty Supercharger for as long as you want with no idle charge at all. The mistake is assuming that logic carries over to every network. It does not; Electrify America's $0.40 per minute applies on a flat 10-minute clock regardless of how busy the station is.
The unwritten etiquette that avoids most of this
Formal fees are only half the picture. Public charging etiquette exists because a charging bay is shared infrastructure with no attendant enforcing manners, and a handful of habits keep the system working for everyone, including you the next time you are the one waiting.
- Move at 80 to 90%, not 100%, when others are waiting. DC fast charging slows sharply past roughly 80% state of charge to protect the battery, so the last 10 to 20% can take longer than the first 80% combined. If a line is forming, topping off the last stretch elsewhere is the considerate move, and it is also the move that keeps you off the idle-fee clock.
- Never unplug someone else's car. Even if it looks finished, that is not your call to make without permission. Some drivers leave a note or a hanging tag with a phone number authorizing others to unplug if they are running late; absent that, leave it alone unless it is a genuine emergency.
- A charging stall is not a parking space. Once your session ends, the spot belongs to the next person, not to the rest of your shopping trip. This is the exact behavior idle fees exist to discourage.
- Set a phone alarm or use the network's notification. Tesla, Electrify America, and most apps will text or push a notification when your session completes. Turning that on is the single easiest way to never pay an idle fee by accident.
- Check the station's specific policy before you plug in, especially on EVgo, ChargePoint, or Blink. Because those networks do not guarantee one company-wide rate, the app screen you see right before starting a session is the only reliable source for what overstaying will actually cost at that stall.
Bottom line
Idle fees are not designed to punish normal charging, they are designed to punish the last twenty minutes of dead time after you have already gotten what you came for. Know your network: Tesla's rate depends on how busy the station is and varies by site, Electrify America's does not, and EVgo, ChargePoint, and Blink all leave it to the individual station, so check the app. Combine that with the basic courtesy of moving once you are done rather than once you notice, and idle fees stop being a real risk and become exactly what they are meant to be: a rule you never actually encounter.

Last factually verified: October 19, 2026. Electrify America's $0.40 per minute idle fee and 10-minute grace period were read directly from electrifyamerica.com (its FAQ), and the Congestion Reduction Effort's 85% session cap, 10-minute window, and "85% Limit" banner from its Congestion Reduction Effort page. ChargePoint's Service Fee amounts ($0.25 AC / $0.49 DC for account holders; $0.49 / $0.99 for guests; page last updated 6/16/2026) were read directly from chargepoint.com. Blink's $0.49 access fee and host-set pricing were confirmed against Blink's driver FAQ as indexed by search. Tesla blocks automated reading of its site, so its figures come from search-indexed Tesla support pages (which confirm the 5-minute grace period and the occupancy-based structure) and third-party guides dated October 2026 (which report the $0.50 and $1.00 rates and a newer battery-level congestion fee); we could not confirm Tesla's current U.S. dollar rates from a Tesla page, so they are described as commonly reported. EVgo's per-station policy could not be confirmed from an EVgo page and is unchanged from the earlier version.
