Is an Efficient Wi-Fi Router Worth It in Germany? (2026)
With electricity at €0.370 per kWh in Germany, an efficient Wi-Fi router pays for itself in 2.6 years, even if your current one still works.
An efficient Wi-Fi router cuts electricity by 60%: about 105 kWh, worth €38.85 a year in Germany. Worth it now
- From
- Old modem plus separate router, about 20 W, about 175 kWh a year
- To
- Current combined gateway, about 8 W, about 70 kWh a year
- Usage
- Always on
| Scenario | You pay | Payback | Net over its life |
|---|---|---|---|
| Replace a working Wi-Fi router now | €100.00 | 2.6 years | €133.10 |
| Replacing anyway: choose the efficient one | €100.00 | 2.6 years | €133.10 |
Prices are typical figures; type your own quotes above. Net over its life is the total saving over the years it lasts minus what you pay. It ignores inflation, interest and changes in electricity prices, which is conservative while prices are rising.
Our take
Marginal. Worth it only if the equipment is old enough to be replaced for other reasons, or if your provider gives you a new gateway for free.
How the two models compare
| Inefficient | Efficient | |
|---|---|---|
| Model | Old modem plus separate router, about 20 W | Current combined gateway, about 8 W |
| Electricity per year | 175 kWh | 70 kWh |
| Cost per year here | €64.75 | €25.90 |
| Over 6 years | €388.50 | €155.40 |
Usage behind these figures: always on. Basis: Typical measured draw of older separate units versus a current combined gateway, 24 hours a day. The Wi-Fi Router page prices the appliance at its own typical hours, which you can change there.
The same upgrade in other countries
| Country | Saving per year | Payback, replacing now | Payback, replacing anyway | Verdict |
|---|---|---|---|---|
| United States (average) | $19.26 | 5.2 years | 5.2 years | Worth it when replacing |
| United Kingdom | £27.64 | 3.6 years | 3.6 years | Worth it when replacing |

| France | €21.01 | 4.8 years | 4.8 years | Worth it when replacing |

Local electricity prices, with the same purchase price read in local currency, which is a simplification. The saving column is what matters: the higher the price of electricity, the faster any upgrade pays back.
