EIGRP Metric Calculation

fitzybhoy

What is the correct formula for calculating EIGRP metric using only bandwidth and delay?

I have seen different sites providing different formulas, such as:

(10^7/BW*256)+Delay = Metric

((10&7/BW*256)+(Delay*256)) = Metric

If
K1=1, K2=0, K3=1, K4=0, K5=0
then the correct formula is as follows:
Metric = (Bandwidth + Delay) * 256
