Pump is already 220v.
I gave up on this idea when so many more knowledgeable pointed out how
stupid I was.

The meter measures power, not current. It doesn't matter whether you
draw 12A @ 110V or 6A @ 220V (your 5A at 220 isn't correct), you will
pay the same price.

Exactly.

Watts = Volts X Amps

120 V X 10 A = 1200 watts
240 V X 5 A = 1200 watts

And the power company bills for kilowatthours ... 1000 watts consumed for
one hour = 1 kwh

That why the electric meter is called a "watthour" meter.

Here's a scenario maybe even the OP will understand. Suppose a car gets 15
MPG and has a 20 gallon gas tank. Will replacing the 20 gallon tank with a
40 gallon tank reduce what the driver spends on fuel each week? No - because
the car still gets 15 MPG. That's exactly what he's proposing by upgrading
the service to 400 amps ... it won't make ANY difference on the monthly
bill.

How will increasing to 400-amp service cut your electric bill? You
pay by the kilowatt hour, don't you?

It won't (as you know, OP doesn't understand)...

If you read the rest of the post, he's under the delusion that
converting his well pump to 220V from 110V will, by cutting amperage,
halve is bill for it... :(
