Engine size to horsepower
How many cc is one taxable horsepower?
Car insurance counts taxable horsepower, while you know the engine size. Convert one into the other.
- The law multiplies the engine size in cc by 0.007 and rounds to the nearest whole number, with a half rounded up: about 143 cc per horsepower.
- A 1,400 cc engine has 10 taxable horsepower, a 2,000 cc one 14, and 11 horsepower are the engines from 1,500 to 1,642 cc.
- For motorcycles the coefficient is 0.013.

What it means for the premium
No public figure shows how the premium changes with engine size. Our own estimates change with the engine band, and one page shows them for each band. Car insurance by engine size. The market average for the car.
How we work it out
The cheapest estimate for liability comes from our calculation, for the driver of the basic example, in the engine band of the car. How we calculate.
The rule is article 4 of law 722/1977: taxable horsepower equals the engine size times 0.007 for cars and times 0.013 for motorcycles. A fraction under a half is dropped, a half or more goes up. So 1,499 cc make 10.49, that is 10 horsepower, and 1,500 make 10.5, that is 11. Circular Δ18Β 5054857 ΕΞ of the Ministry of Finance, of 28 December 2010, gives the same coefficients.
The law sets the rule for cars that came after it took effect; older ones keep the figure they had. What the registration certificate says always prevails.

Frequently asked questions
What people usually ask
01 Where is the taxable horsepower written?
On the registration certificate, in the field “Φορολογήσιμοι ίπποι” or “Φ.Ι.”. The real power is elsewhere, in field P.2, in kilowatts.
02 How many taxable horsepower is a 1,600 cc engine?
11: 1,600 times 0.007 makes 11.2. From 1,500 to 1,642 cc every engine is 11, and 1,643 becomes 12.
03 Does the same rule hold for motorcycles?
The factor is 0.013. A 600 cc engine has 8 taxable horsepower, a 125 cc engine 2.
04 Does a turbo or a chip change anything?
No. Taxable horsepower comes from the engine size, not the power. A turbocharged 1,000 cc engine stays at 7 horsepower, however many kilowatts it makes.
