Earnings and calculation

That depends on how many kWh you charge at home, the current ERE price and your provider’s commission or fee. At the 4,000 kWh reference volume and a price of roughly €0.10 per kWh gross, that already adds up to a few hundred euros a year before commission. Enter your own mileage and consumption in the calculator for a personal indication; it remains an estimate, not a guaranteed amount.

Multiply the number of kWh by the statutory factor 0.33269 to get the number of EREs, then multiply that by the current ERE price (around €0.46) for the gross value: roughly €0.15 per kWh. Subtract your provider’s commission or fixed fee to get the net figure. Our calculator does this automatically based on your annual mileage and consumption.

The conversion from kWh to EREs is fixed by law (0.33269 ERE per kWh), but the price per ERE isn’t: it’s set by supply and demand on the market, not by the NEa. That’s why the price fluctuates; named sources currently quote €0.36 to €0.51 per ERE. The model also differs per provider: commission, a fixed annual price or a guaranteed rate, which makes the final payment per kWh vary further.

The ERE price feeds straight through into your gross earnings: the higher the price per ERE, the more each kWh charged is worth. At €0.46 per ERE that’s roughly €0.15 per kWh; a higher price means more, a lower price less. Providers sell at different moments, so the exact price at your payout moment partly determines what you receive net.

Gross is the value of your EREs before any deductions: the number of kWh times 0.33269 times the ERE price. Net is what you actually receive after your provider applies its commission, fixed annual cost or other deductions. The difference can be substantial: some providers withhold 10%, others up to 27.5%, or charge a fixed annual price instead of a percentage. Always compare the net indication, not just the gross figure.

This differs a lot by provider: known commissions in our comparison range from roughly 10% to 27.5%. Groen-laden charges 15% of gross proceeds, with a minimum of €34.99 and a maximum of €79.99 per charger a year. Vattenfall withholds 25% but guarantees at least €0.05 per kWh. Always check the exact model for each provider.

Broadly yes: more kWh charged means more EREs, because the conversion (0.33269 ERE per kWh) is linear. But only kWh that meet the requirements count, such as measurement through a suitable MID meter and verifiable data; charging that doesn’t meet those conditions isn’t included. The payment per kWh also isn’t fixed, so charging more doesn’t automatically translate into a proportionally higher payment.

The ERE calculation is based on the grid electricity the MID meter registers at your charge point, in other words the electricity drawn from the grid. Losses that occur afterwards, for example in the cable or while charging the battery, don’t change that meter reading and so aren’t deducted separately. What the meter measures is also what counts for the conversion into EREs.

Not in the standard calculation. The NEa uses a fixed renewable share for home charging (50.5% in 2026), with or without solar panels. The law does have a separate route for power you generate yourself at the same address, open to private individuals too, but with strict conditions: special guarantees of origin for non-grid delivery, a verifier checking the generation, and no operating subsidy. Ask your provider whether it supports this before counting on it.

Yes. The calculator uses the current ERE price (updated every week) and an average assumption of 15% commission, purely as an indication. The actual ERE price fluctuates (named sources currently range from €0.36 to €0.51 per ERE), and your provider’s commission or rate can differ, as can your real charging behaviour. As a result, your final payment can end up higher or lower than the calculator’s outcome.
