When does an EV charging subscription pay off?
A subscription pays off if you charge more kWh each month than the break-even point. Calculate it simply: monthly fee ÷ (basic price − subscription price). For example, if you pay €12/month and save €0.14/kWh, the break-even is approximately 86 kWh/month — roughly 500–600 km with an average EV consumption.
⚡ Tesla Supercharger
Subscription (€12.99/mo.) reduces price from €0.60/kWh to €0.45/kWh. Break-even approximately 87 kWh — suitable for regular long-distance travel.
🚀 Ionity Passport
Passport (€11.99/mo.) reduces price from €0.79/kWh to €0.55/kWh. Break-even around 50 kWh — just one longer stop at an Ionity station pays off.
⚡ Fastned Gold
Gold subscription (€9.99/mo.) reduces price from €0.69/kWh to €0.55/kWh. Break-even 71 kWh — great for frequent users of the Fastned network.
Frequently Asked Questions about Charging Subscriptions
What are the advantages of subscription tariffs?
Lower price per kWh, predictable costs and comfort of single billing. For regular users of public charging they can save hundreds of euros per year. Plus they eliminate the need to watch current charging prices.
When does a subscription not pay off?
If you charge mostly at home or your monthly consumption at public stations does not exceed the break-even point calculated by our calculator. For occasional users of public charging it is better to stay with pay-as-you-go billing.
Can I combine multiple subscriptions?
Yes — for example Tesla Supercharger for long-distance routes and Fastned Gold for local charging. It is important to calculate total costs and compare them with individual tariffs or combinations without subscriptions. Most offer monthly commitment without contract.
How do I find out my average consumption?
EV consumption is usually stated in the technical documentation or manual (WLTP standard). Real consumption is typically 10–15 % higher than WLTP in summer, 20–40 % higher in winter. Average for a mid-size EV: 17–20 kWh/100 km.
Tariff prices are indicative based on publicly available price lists. Actual conditions may depend on contract and time of charging.
