2,000 km of Supercharging or €250: which is worth more, calculated

Published July 18, 2026 · verified July 13, 2026

A dated, figure-by-figure example: we convert the referral's 2,000 km of Supercharging into euros to see whether the €250 alternative is really the better deal.

The choice you make when ordering

The referral gives you a choice between 2000 km of free Supercharging or €250 off. Many people pick the kilometres by reflex — “free” always sounds bigger than “€250”. Here's the maths, using the rate assumption set out in our page on charging costs.

Step 1: how many kWh in 2,000 km?

With type-approved consumption of around 15 kWh/100 km (Model 3 / Model Y RWD, per Tesla's own figures), 2,000 km works out to roughly 150 kWh.

Step 2: what's that worth in euros?

Using the working assumption of €0.42/kWh (check the live app price on the day), 150 kWh comes to:

The verdict, calculated

On this assumption, the €250 is worth roughly four times more than the 2,000 km, in real money. The gap narrows if your real-world consumption is higher (motorway driving, winter, spirited driving: 18–22 kWh/100 km) or if the rate you actually pay is above our assumption — but it rarely crosses €250.

Two reasons that €63 is an upper bound, not an estimate

The conversion above prices the kilometres at the Supercharger rate, which is the standard way to do it and quietly generous. Both corrections push the same direction, and neither appears in any comparison we have seen.

It assumes you would have Supercharged. Free kilometres only save you what you would otherwise have spent. Charge mostly at home and those kilometres displace cheap domestic electricity rather than expensive roadside energy — so their real value to you is closer to your home rate than to €0.42/kWh. For a driver who Superchargers rarely, the €63 could be a small fraction of that.

It assumes you use them all. Supercharging credit expires; a euro deduction taken at order does not. Whatever share you fail to spend before the deadline is worth exactly nothing, and it is the low-mileage driver — the same one for whom the kilometres were already worth least — who is most likely to leave some unused.

So the honest reading of the table is that €250 versus roughly €63 is the most favourable case for the kilometres. Adjust for how you actually charge and whether you would spend them in time, and the gap widens rather than closes.

The one case that genuinely reverses it

It is worth stating the exception properly rather than leaving the impression that the euros always win, because for a specific driver they do not.

If you have no home charging at all — street parking, an apartment without a socket — then Supercharging is not your expensive option, it is your only option. Every kilometre of credit displaces energy you were certainly going to buy at that rate, so the full €63 applies rather than an eroded fraction of it, and it arrives as convenience on trips you were making anyway.

That still does not reach €250 on this assumption. What it does mean is that the choice is closer than the headline number suggests for that driver, and that a table cannot make it for them. The rule we would give: if you have a home charger, take the euros; if you have no way to charge at home, do the sum with your own rate before deciding.

When the kilometres are still the right call

If you Supercharge a lot (regular long trips, no home charging), 2000 km represent a genuine saving in time and hassle, even if their euro value is lower than €250. The right choice depends on how you use the car, not just the headline number.

What to remember

• 2000 km of Supercharging is worth, on our rate assumption, roughly €60–75 — not a symbolic figure.
• The €250 discount is, for most drivers, the better deal in real money.
• Always check the live Supercharger price in the app before doing your own maths.
