That very simple calculator is missing both ambient and terminal temperatures ,raceway types and power factor...all having a major factor in VD computation.

Try this one as it takes everything into consideration inclusive of raceway types and temperatures. Also the VD formula is not a simplistic 2KID but rather IEEE 141 exact formula.
