This calculator is a great starting point for homeowners weighing the high upfront cost of a geothermal system against a standard heat pump. It clearly breaks down how federal tax credits and local rebates impact your bottom line, and calculates a straightforward payback period based on your estimated monthly energy savings. Keep in mind that it assumes energy prices remain constant and doesn't factor in potential differences in maintenance costs, but it provides a solid, easy-to-read verdict to help guide your decision.
