Device price calculator
Estimate how much a device costs to run with Nord Pool electricity prices, tariffs, and VAT, then compare Smart Kilowatts schedules with always-on, timer, and custom baseline usage.
What does this calculator estimate?
The calculator models a device or group of devices against historical Nord Pool prices. It combines power, active hours, schedules, tariff settings, and selected baselines to estimate running cost over past months.
Why compare smart scheduling with normal usage?
A smart schedule only matters if it beats a realistic alternative. Comparing against always-on use, a fixed timer, or a custom baseline shows whether price-aware control actually reduces the cost for the device.
How do tariffs and VAT affect the result?
Nord Pool market prices are only part of the cost. Supplier tariff components, VAT, and saved tariff settings can change the total ct/kWh used in the calculation, so tariff-aware results are closer to a real bill than spot prices alone.
Which devices fit this calculator?
The calculator is useful for flexible loads such as EV chargers, boilers, heat pumps, pumps, batteries, heaters, lighting, and appliances that can be shifted or limited by time, price, season, or day type.
How to use a calculation in automation
Use the result to decide whether the device should follow a Smart Kilowatts rule, a simpler timer, or no automation. Compatible hardware and plans can then turn the tested schedule into real device control.
Frequently asked questions
Is this the exact price on my electricity bill?
No. The calculator estimates costs from available price and tariff data. Your final bill can still include supplier terms, fixed fees, regulated charges, and other adjustments outside the modeled scenario.
How many historical months should I use?
Use one year for a balanced default. Use two or three years when you want to smooth seasonal changes or compare behavior across more market conditions.
Why compare against a non-smart baseline?
The baseline shows what the same device would cost without price-aware scheduling. This makes savings or losses visible instead of only showing the smart schedule cost.
Do I need a Nord Pool tariff?
You can calculate from market prices alone, but choosing a tariff gives a better estimate when your real electricity plan adds supplier, VAT, or time-based components.
Which devices can be modeled?
Any device with predictable power and flexible runtime can be modeled. Common examples are EV chargers, boilers, heat pumps, batteries, pumps, heaters, and appliances.
