Is it cheaper to charge a Toyota Bz4x SUV at home or in public in Denmark?
At 15.000 km/year it's cheaper to charge a Toyota Bz4x SUV at home than in public: home charging with your own box costs about 4.958 kr./year — including the box and installation spread over 5 years — versus about 7.176 kr. for public pay-as-you-go charging, roughly 2.218 kr. (31%) less a year. But that assumes you can install a charge box at home; if you live in a flat without your own parking, public charging is your baseline.

Assumptions: 14,4 kWh/100 km · 15.000 km/year · a house where you can install a charge box · home price as a regional average (Energi Data Service, as of 3. jul. 2026) under the reduced 2026–27 electricity tax · the home figure includes the box and installation (about 1.798 kr./year spread over 5 years) · public charging at 2,99 kr./kWh (OK, no subscription, as of 3. jul. 2026). ≈10 % charging loss is included on every purchased kWh — at home and on public chargers.
Can't charge at home?
Everything above assumes you can install a charge box at home. If you can't — say, in a flat without your own parking — public charging is your real baseline, and a charging subscription can often make it cheaper.

Summary
The maths is simple: home electricity with your own box costs about 1,32 kr./kWh under the reduced 2026–27 electricity tax, while public charging with no subscription costs 2,99 kr./kWh — more than twice as much per kWh. Even once the box and installation (about 1.798 kr./year, spread over 5 years) are counted, home charging comes to about 4.958 kr./year versus 7.176 kr. in public at 15.000 km. The catch is that it needs somewhere to fit the box: without your own parking, public charging — or a charging subscription — is the way forward. Figures are illustrative and rest on regional averages for electricity and grid tariffs.
