 If you look at the units carefully, you'll notice that they almost all cancel out except for \$\frac{\text{\$}}{\text{month}\cdot\text{W}}\$ ((The "hrs" of "24 hrs" cancels with the "h" of "kWh" since kWh means kW \$ \times\$ hr .)) If you look at the units carefully, you'll notice that they almost all cancel out except for \$\frac{\text{\$}}{\text{month}\cdot\text{W}}\$ ((The "hrs" of "24 hrs" cancels with the "h" of "kWh" since kWh means kW \$ \times\$ hr .))
  
-That number means that it costs 0.102784 %%$%% per month for each Watt of power that's continuously drawn.  So if you multiply that number by the power consumption of the device, the \$\text{W}\$ will cancel out and you'll get a result in \$\frac{\text{\$}}{\text{month}}\$, which is the monthly electricity price for that device.  For example:+That number means that it costs %%$%%0.102784 per month for each Watt of power that's continuously drawn.  So if you multiply that number by the power consumption of the device, the \$\text{W}\$ will cancel out and you'll get a result in \$\frac{\text{\$}}{\text{month}}\$, which is the monthly electricity price for that device.  For example:
