Explanation: How to use the Electricity Cost Calculator correctly
This calculator helps you break down your electricity costs in an understandable way – without Excel and without complicated formulas. You enter your annual consumption in kWh (kilowatt-hours), the usage price in ct/kWh, and the base price per month. This creates two cost blocks: usage costs (kWh × price) and fixed costs (base price × 12). The calculator shows your annual and monthly costs as well as the distribution, so you can see immediately which part is "fixed" and which part increases with your consumption.
For a quick start, you can choose a household preset. These values are rough guidelines and do not replace an actual bill, but they help with classification. The Price Scenario area is particularly useful: use the slider to simulate how a higher or lower usage price affects your total costs – e.g., if your contract expires, your provider adjusts prices, or you have found a new tariff. Additionally, the calculator calculates a savings potential by assuming a percentage reduction in consumption (e.g., 10%). This isn't magic, but a practical orientation: small changes in daily life have a significant impact at high kWh values.
The optional tariff comparison is perfect if you want to compare two offers. Enter the usage price and base price of the alternative tariff – the calculator will then show the annual difference. Important: A tariff with a low usage price can become unattractive due to a high base price (and vice versa). This breakdown is intended exactly for that purpose. If you use these values frequently, you can save them locally in your browser – this is convenient and data-efficient because nothing is sent to a server.
FAQ
Where can I find my annual consumption (kWh)?
On your last annual bill, often also in the customer portal or in your provider's app. If you have just moved in, take a guideline value and adjust it later – even small corrections make the calculation significantly more accurate.
Why are the base price and usage price separate?
The base price is the fixed portion (e.g., meter operation, billing), while the usage price scales with your consumption. The separation shows whether saving through consumption really helps much or if the fixed portion is particularly high for you.
What does "ct/kWh" mean and why not "$/kWh"?
Electricity prices in many regions are often quoted in cents per kWh. 35.0 ct/kWh corresponds to $0.35/kWh. The calculator converts this internally so that the results can be displayed cleanly in dollars.
Does the result already include taxes and network fees?
Usually yes, because these components are normally already included in the stated usage price and base price. If you are calculating special cases (e.g., net prices), you must adjust accordingly.
How realistic is the savings potential in percent?
This depends heavily on the household. 5–15% is achievable for many households (LED, avoiding standby, efficient appliances, washing temperatures, hot water). The slider is intentionally designed as a "what-if" scenario so you can quickly see the scale.
Why can a tariff with a cheaper usage price still be more expensive?
If the base price is significantly higher, it can eat up the savings – especially with low consumption. That is why a comparison is always worthwhile as a total sum per year, not just via a single metric.
