"VCR (stand-by)" is the amount of time that your VCR is plugged in, but not being used. For example, if you use a VCR for 1 hour every day, your VCR is in "stand-by" for the remaining 23 hours of the day. Please enter "23" in the first field and select "hours/day" in the second field. Your cost per month and cost per year will be automatically calculated.
