Reading your dealer fee impact result
How dealer fees typically get built in
Rather than appearing as a separate charge, a dealer fee usually gets folded into the total price the loan finances, which raises both the loan amount and the monthly payment without a clearly labeled line item. This makes it easy to miss unless you compare the financed price against a cash quote for the same system, or ask your installer directly what markup, if any, applies to a specific loan product.
Why the fee costs more than its face value
Because the fee is financed rather than paid upfront, you pay interest on it for the full loan term, which adds to its real cost. On a $28,000 system with a 15% dealer fee financed at 6.99% APR over 20 years, the $4,200 fee ends up adding about $7,809 to the total cost after interest, since no federal tax credit currently applies to offset any part of it. The CFPB's origination fee explanation covers a closely related fee type that works similarly.
Why installers charge dealer fees at all
Lenders often pay installers a fee for originating and arranging the loan, which compensates the installer's sales and administrative work but isn't free money, it comes from somewhere in the pricing. Some installers pass this cost through to the financed price, while others absorb it or don't use lenders that charge it in the first place. The CFPB's issue spotlight on solar financing covers this kind of pricing practice in more detail.
How to compare quotes that may hide different fee levels
Two installers quoting the same monthly payment can have very different underlying system prices and dealer fees, so always ask for the base cash price alongside the financed price to see the actual markup. The total cost including financing fees calculator takes a broader look at every fee that can show up in a financed solar quote. The total cost of ownership calculator is a useful next step once you have this result.
What to ask before signing
Request the base cash price, the exact dealer fee percentage if one applies, and whether a cash-price discount is available if you skip financing through the installer's preferred lender. Comparing that against outside financing through the contractor financing vs bank loan comparison often reveals meaningful savings, and the loan APR impact calculator can show how sensitive your total cost is to the rate difference alone. The federal solar tax credit calculator and total cost of ownership calculator can help you see the full picture beyond just the fee.
