What is Fiscal Power (CVF)?
Fiscal Power (Potencia Fiscal) is a calculated value used in Spain mainly for determining annual road tax (IVTM) and sometimes for registration purposes. It is not the same as the engine’s actual horsepower.
How to Use
Enter the engine displacement in cubic centimetres (cm³) and the number of cylinders. Click “Calculate” to get the CVF value. This is an approximation based on the standard Spanish formula.
Note: Always verify the official CVF value from your vehicle’s Ficha Técnica for final tax calculations.
