Take the amount of kWh that the meter states that you have used and multiply it by the cost of a kWh in your area.
Another Answer
Subtract the energy meter reading from the previous billing period from that from the current billing period to determine the number of kilowatt hours used during that period. Multiply this difference by the cost per kilowatt hour charged by your energy provider. Note, however, some energy providers have a complicated billing system (tariff) in which the cost per kilowatt hour changes according to the amount of energy you use: x cents per kilowatt hour for the first so many kilowatt hours, y cents per kilowatt hour for the next so many kilowatt hours, and so on. Additionally, there may be a multiplication factor based on the changing price of fuel.
To calculate three-phase meter reading in kWh with CT coils, you need to first determine the current ratio provided by the CT coils. Multiply the current readings obtained from the CT coils with the current ratio to get the actual current values. Then, multiply the actual current values with the voltage and power factor to get the power in each phase. Finally, sum the power in each phase and multiply by the time in hours to get the kWh reading.
The multiplication factor (MF) in a three-phase meter is typically calculated by dividing the rated primary current of the current transformer by the maximum current that can be measured by the meter. The formula is MF = Rated Primary Current / Maximum Measurable Current. This factor is used to adjust the meter reading to reflect the actual current flowing in the circuit.

mf is ratio of CT ration of meter box to CT ration written on meter. ex: CT meter box: 30/5, Meter ct ration 1/1. MF : (30/5)/(1/1)= 6
multiplying factor = Line CT Ratio / Meter CT Ratio Usually it is mentioned on Meter that MF = 1 if CT Ratio is 200/5 or MF = 2 if CT Ratio is 400/5. There can be an additional multiplication factor that would be mentioned on the meter.
It's given by f=ks, where k=2 and s=9
The question is incomplete, because there are no mention about CT & PT ratios. 600VA 5 can not be CT ratio.
Multiplication factor can be derived from Meter CT, Meter PT, Connected CT and Connected PT values.

A LT-CT energy meter is a low tension current transformer energy meter designed to measure and record the energy consumption in low voltage electrical systems. It uses a current transformer to step down the current to a level that can be accurately measured by the meter. These meters are commonly used in residential and small commercial applications to monitor electricity usage.

To calculate copy number from a Ct value, you can use the formula: Copy number 2(Ct reference - Ct target), where Ct reference is the Ct value of a reference gene and Ct target is the Ct value of the gene of interest. This formula helps determine the relative amount of the target gene compared to the reference gene in a sample.
