I have a 1200 square foot 3-bedroom house that has a 100 amp panel. Because of rising gas costs I've had an electrician install a 40-amp plug in the kitchen for use with an electric range. My question is a straightforward one, is 100 amps sufficient for this changeout? My dryer is electric and we have done a garage conversion so there are additional outlets now but there aren't any devices in there that could be considered heavy current draws (lighting, stereo equipment, etc.)
My Heat/Air system is gas/electric but gas is used mainly in the winter rather than the heat pump.

The addition of an electric range brings the calculated load to 74 amps.

This does not include any electric water heater or the auxiliary electric heat in the heat pump.

If either of these two loads exists, then the 100 amp service will not be large enough to allow the range conversion to electric.

Well I guess I'm okay then? I have a gas water heater and the heat pump auxiliary electric is busted (I use gas only in winter). I made a mistake in the original post, the plug is a 50-amp but the proposed range is only 40 amp.
Thanks for the input!

Looks like your good to go!
