The nice thing about it is that this isn’t actually heating an area, it heats you and the mattress/blankets around you, basically making a microclimate in your sleepy cocoon. Very very efficient, even if your electric rates aren’t great (mine really aren’t either, but it still barely touches it, they just don’t use a lot of electricity). I put my heated pad under a padded pad to help retain and even out the heat, and it helps a lot.

Happy to help either way! So here’s some more info!

Most of the below comes from that link-

60-100 watts is roughly average energy use, but you can get lower, and smaller pads will use less.

Energy Cost = (Wattage x Usage Hours) / 1000 x Electricity Rate

For example, let’s assume your heated mattress pad has a wattage of 75 watts, you use it for 8 hours per night, and your electricity rate is $0.12 per kWh. The calculation would be as follows:

Energy Cost = (75 watts x 8 hours) / 1000 x $0.12 = $0.072 per night

For one mattress pad for a 30-day month with the above assumptions, it would run you a whopping $2.16/mth.
