Comparing cost of oil and electricity for heat

I installed a Goodman split system 9 years ago with a 16 SEER heat pump. The heat pump is super efficient, but only good down to around 32 degrees F. In the fall and spring months, it heats the house at a cost of around $25-30 a month.

The propane side of the heating equation is not so good, although the furnace is rated at 95% AFUE (Annual Fuel Utilization Efficiency) and it is maintained annually.

BH, curious if the geothermal system that cost $150 a month to run includes the proportional installation cost of the GTH system.
