GoodLeap Solar Loan Calculator
Model what a GoodLeap-style solar loan will actually cost, including the dealer fee the installer rolls into your financed amount. Enter your system price, dealer fee, APR, and loan term to see the monthly payment, total interest, and true cost of borrowing.
How to read these numbers
The calculator shows how much a solar loan actually costs when the installer rolls a dealer fee into the amount financed. The dealer fee is a commission the installer pays to GoodLeap or whichever point-of-sale lender originated the loan. Common dealer fee ranges run 15% to 30% of the system price, which inflates both the principal and the total interest paid.
If the installer offers you the same system at a lower cash price, the real cost of financing is the difference between the loan total and the cash price. In the default example above — a 25,000-dollar system at 25% dealer fee, 6.99% APR, 25-year term — the loan total of 66,201 dollars is 2.65 times the cash price.
These are indicative figures
Actual GoodLeap loan terms depend on your credit profile, state, loan structure (Standard, Flexpay, Go Green Refi), and the dealer fee your installer negotiates with GoodLeap. Use this calculator as a starting point, not a final quote. A real quote comes from your installer in writing.
What the calculator does not model
- Federal tax credits. The 30% homeowner solar credit (Section 25D) ended for systems completed after December 31, 2025, so the calculator does not subtract one. If your system was completed earlier, the credit lowers your net cost, but it only reduces the loan balance if you use it to prepay.
- Utility bill savings. The solar system should reduce your electricity bill, offsetting part of the loan payment. Savings depend on your utility rate, system production, and net metering policy.
- State tax credits and rebates. Many states offer additional solar incentives that lower effective cost.
- Promotional-period loans. If your installer offers a 0% interest period, the math changes significantly. Those loans typically accrue interest retroactively if the balance is not paid in full by the promotional end date.
