## Country-Specific Price Calculations
The Tibber API provides the raw spot price (`energy_price` attribute) and tax/fee component (`tax` attribute) on every price sensor. Since the exact composition of `tax` varies by country, you can use these attributes to build **your own** country-specific calculations with Home Assistant templates.
The Tibber API provides the raw spot price (`energy_price` attribute, in ct/kWh) and tax/fee component (`tax` attribute) on every price sensor. Since the exact composition of `tax` varies by country, you can use these attributes to build **your own** country-specific calculations with Home Assistant templates.
:::tip Why templates instead of built-in calculations?
Tax rates and energy fees change regularly (often annually). Using `input_number` helpers in Home Assistant keeps your calculations up-to-date with a simple UI adjustment — no integration update needed.

Norway and Sweden have their own fee structures, but the same pattern applies — use `input_number` helpers for the fixed/semi-fixed components and `energy_price` for the spot price.
