I'm trying to get a very rough estimate of the cost of electricity to run a
well pump.

Here's what I know: The pump is 230volt, 3/4 HP (from info on inside cover
of control box).
I do not know flow rating of pump, age, make or anything else about it. Just
moved into this house 2 1/2 years ago and the well and pump go back before
that.

On some website, I saw an estimate of 140 kWh per year for a 3/4HP well
pump. This was based on 253 gallons/day usage. Well, with 365 days a year,
it calculates out to about .0015 kWh/gallon. On my last electric bill, the
cost was $.066 per kWh. Also, on my last city water bill, usage was 15,000
gallons.
Bottom line, this would come out to $1.48 for electricity to pump the same
15,000 gallons. (The variable part of the city water bill was $80 for those
15,000 gallons).

For anyone who's looked into the energy cost, does that estimate look way
off?

Bear in mind that I'm not trying to estimate future bills. I'm trying to get
a rough, but accurate estimate so I know if there's a big difference in the
cost of city water supply vs. water pumped from the well.

My house is served by a city water supply AND has a private well. When I
moved in (up until a couple of days ago), the well supplied water for the
outside faucets and the sink in the garage. The rest of the house is
supplied by the city water. Just last weekend, the well pump stopped
working. Of course, the big question is whether it's worth the $ to get it
fixed. My first thought was that if the per gallon cost was similar, then
there's no use fixing the well pump. If the well is MUCH cheaper, then it's
worth looking into further and getting estimates.

$1.50 definitely is MUCH cheaper than $80. Just looking for a reality check.

Many thanks!

A reality check is that replacing the pump is going to run a big bill.
My guess (and it is a WAG), at least $1500 minimum. Takes a long time
to amortize that. Another WAG is that with a working pump the cost of
well water is way under what the city charges.
