I think it's useful at this point to emphasise the "round trip" element
of the calculation here. Far too many diyers seem to think either:

All the current supplied to the load is consumed within it.

Or,

The current the load requires is consumed within it and whatever is left
over is returned to the grid and knocked off your bill.

Peeps, please remember that provided there isn't an earth leakage fault,
*all* the current your domestic installation draws is returned to the
power company. Not only that, but the average *voltage* supplied to your
house over that same 3 months by the power company is precisely zero. So
you're paying all that money every quarter for **** ALL.
