THIS CONSIDERATIONS SHOULD BE STRICTLY FOLLOWED: SOUND ENGINEERING AND ACCEPTABLE ECONOMICS; 1.DEFINE DEMAND LOAD - AFTER APPLYING POWER FACTOR AND EFFICIENCY FOR MOTOR LOADS AND ACTUAL SYSTEM VOLTAGE AND PHASE. 2. ONE WAY LENGTH OF WIRE OR CABLE - FT. (AWG) OR MTR. (SQ.MM) SELECTION 3. MULTIPLY BY 125% TO THE CALCULATED LINE CURRENT TO GET AMPACITY REFERENCE 4. LOOK OR SELECT THAT NEAREST RESULT TO ANY LOCAL CABLE SUPPLIER CATALOG OR NEC TABLES AND MATCH IT TO CORRESPONDING CABLE SIZE. 5. APPLY DERATING FACTORS - ALSO AVAILABLE TO NEC OR CABLE SUPPLIERS AND DEFINE THE FF: A. MEDIUM OF INSTALLATION - PVC OR RSC CONDUIT, CABLE TRAY OR CABLE LADDER OR TRUNKING, THROUGH, ETC. B. AMBIENT TEMPERATURE - INDOOR OR OUTDOOR? C. GROUP FACTOR - CONSIST OF CABLE SPACING AND DISTANCE TO WALL OR INSIDE CONDUIT INSTALLED IN TRAYS OR UNDERGROUND 6. APPLY DERATION IN WHICH RESULT IS LESS THAN ONE (1) TO THE PRE-SELECTED CABLE - THIS IS NOW YOUR ACTUAL FOR SELECTED CABLE 7. DEFINE REQUIRED OR ACCEPTED VOLTAGE DROP IN PERCENT VALUE 8. NOW USE THIS FORMULA: VDapp(APPLICABLE VOLTAGE DROP) = %Voltage Drop x Actual Voltage x 1000 divided by Derated Current x One Way Length x 100 9. THE RESULT WILL HAVE A UNIT OF -- mV/A.Mtr OR MILLIVOLT PER AMPERE-METER 10. NOW COMPARE IT TO AVAILABLE TABLES FOR VOLTAGE DROPS OF CABLES - IF IT IS LOWER THEN SELECT THE NEXT SIZE OR WHICH EVER MEET THE REQUIREMENT.
You need the voltage drop per meter, from data on the cable, and then multiply by 500.
Alternatively find the resistance per metre of a single cable of the same wire size, from wire tables, then multiply by 2 x 500 x resistance (in ohms) x current (in amps).
You need two more pieces of information: (i) what is the current being drawn, or the load in kVA, (ii) how thick is the cable. Then look up the wire resistance in ohms per meter for the cable, multiply by the length (500) and multiply by the current, then that is the voltage drop.
You have to know the connected load amperage is at the end of the cable to do the calculation.
This calculation can not be made. An amperage load at the end of the electrical run must be stated.

Compute means to figure out the question and get an answer.
compute means calulate
the present tense of 'compute' will be 'computing'
Computed is the past tense of compute.

The plural noun forms of the verb to compute are computations and computers.
The word "compute" comes from Latin. See etymology in Answers.com.
