Calculate PACE financing for energy improvements
A PACE loan—short for Property Assessed Clean Energy financing—lets homeowners and commercial property owners fund eligible energy‑efficient upgrades and repay the balance through a special assessment on their property tax bill. Use our PACE loan calculator above to model your monthly payment, total interest cost, payback period, and return on investment (ROI) before you commit.
In 2025, residential PACE programs operate in more than 20 states and the District of Columbia, typically offering fixed APRs between 3 – 9 % and terms up to 30 years. Because the assessment is tied to the property—not your personal credit—PACE can make high‑impact upgrades such as solar panels, high‑efficiency HVAC, and insulation improvements cash‑flow positive from day one.
The program administrator pays your contractor upfront. You then repay the principal and interest as a line item on your property tax bill—usually once or twice a year—until the balance is satisfied.
Eligibility is based on property equity, current mortgage status, and being up‑to‑date on taxes—credit score checks are rarely required. Your state or municipality must also authorize PACE programs.
Yes. The assessment generally stays with the property, so the new owner assumes the remaining payments—subject to lender approval if they are taking out a new mortgage.
Interest on PACE assessments may qualify as deductible property tax interest. Consult a tax professional to confirm your individual situation.
Some lenders require the PACE lien to be settled or subordinated before refinancing. Check with your mortgage provider during the application process.
