The Mechanic Nobody Explains at the Kitchen Table
0% financing sounds like a lender doing a homeowner a favor for free. It is not. The lender charges the contractor a higher merchant fee to offer the homeowner 0%, generally a percentage of the financed amount, in exchange for funding the job upfront and carrying the payment-collection risk. Deeper promotional structures, deferred interest, true 0% APR, same-as-cash, no payments for 12 to 24 months, carry a materially higher fee, roughly 8% to 25% or more, than a standard reduced-rate installment loan, which runs closer to 2% to 4% effective, because the lender is subsidizing the interest the homeowner would otherwise owe.
What a Live Rate Sheet Shows
A contractor’s own live EnerBank and Regions financing page makes the trade-off concrete. A 12-month no payments, no interest deferred plan reverts to a 17.99% fixed APR on any unpaid balance once the promotional window closes, versus a standing 6.99% APR installment option with no deferral at all. The 0%-now option is not free financing. It is a bet that the homeowner pays off the balance before the higher reversion rate applies, and if that bet does not pay off, the homeowner is the one who ends up paying for the promotion after all.
One caveat is worth stating plainly: the contractor page carrying these numbers dates its rate disclosure to January 1, 2022, and notes the rates are subject to change. Treat the deferred-interest structure and the reversion mechanic as reliable, and confirm the exact current rate directly with EnerBank or Regions before quoting a homeowner a specific number.

One independently cited historical GreenSky rate sheet showed standard installment loans priced at a 0% to 2.75% dealer fee, versus 11.5% to 18.5% dealer fee on true 0% APR promotional plans, on the same lender’s own pricing. That is roughly a 4 to 7 times fee multiple between the two structures, and it is the clearest illustration of how much more a contractor is charged to offer the deepest promotional financing versus a standard installment option.
Who Pays, in Plain Terms
Two things can be true at once. The contractor is the one billed the higher dealer fee for offering 0%, and that fee, because it cannot be surcharged separately, gets built into the overall bid price, which means the homeowner is paying for it too, just indirectly, through a higher total price rather than a labeled interest charge. And if the homeowner does not pay off the balance before the promotional window closes, they pay for it a second way, through the reversion rate, which can run considerably higher than a standard installment APR.
Free financing is really a pricing decision with the cost moved somewhere less visible. Understanding where it moved is the whole point of asking the question before signing.
