Is this the riight calculation for my energy usage?

If my energy price was 12p/kwh and im using 4*600w hps. Would this be correct to work out my energy price? 0.12(price of kwh)*2.4(kw of lighting)*12(hours lights on a day)*7(days there going to be on)*8(weeks im going to be flowering)=193gbp

sounds right
or u can multiply volts times amperes to get a more accurate wattage
