Your Pay-in-4 Has No Rate Ceiling. New York Just Proposed One: 16%, Fees Included.

If you’ve ever split a purchase into four payments, nobody told you what that plan costs as a rate. There isn’t one to tell you.

That’s not an oversight. Pay-in-four sits outside most of the rules that govern a credit card, and that gap is exactly why it grew.

New York wants to close it.

The number doing the work

On July 15, the New York Department of Financial Services published proposed rules that would make buy now, pay later lenders get a state license and follow a credit-card-style rulebook. The centerpiece is 16%, the interest ceiling already in New York law.

The interesting part is one phrase: inclusive of fees. The cap would count origination charges, Regulation Z finance charges, and anything a lender calls a fee that actually works like interest.

Translation: you can’t route the cost around the ceiling by renaming it.

Penalty fees get an $8-per-incident safe harbor, and charging more takes the superintendent’s sign-off. Total penalties on one loan can’t exceed what you financed in the first place. No stacking several fees onto one missed payment. No surcharge for paying by one method instead of another, unless you asked for expedited service. No prepayment penalty.

Then comes the furniture every credit card already has and pay-in-four mostly doesn’t. Disclosures before and after the purchase. Periodic statements. A real billing-error process: you get 60 days to report a problem, the lender has 30 days to acknowledge it and 90 days to resolve it. If somebody uses your account without permission, you’re on the hook for the lesser of $50 or whatever they got before you called.

Lenders would also have to run “reasonable risk-based underwriting,” looking at your income and debt before handing you a fourth plan.

Where the money actually leaks

Here’s what the pitch leaves out. “Zero interest” is often literally true, and it’s also not where the cost lives.

The cost lives in the late fee, and in four plans running across three apps with four different due dates. It also lives in what happens when a charge goes wrong and there’s no formal place to take it.

New York’s proposal leaves the zero-interest part alone and goes after the rest. That’s the right target.

What to do

You don’t need to do anything today. This is a proposal, it’s New York only, and the timeline is slow: comments close September 14, the rules take effect 180 days after adoption, and existing lenders then get 45 days to file for a provisional license and keep operating while it’s pending. Realistically that’s 2027.

If you use these plans and you want a say in the terms, the comment file at DFS is where it counts. That window closes September 14.

The move that works in every state, right now, is duller. Open each app you’ve used and find the late fee and the grace period, because you almost certainly agreed to terms you never read. Write every active plan and due date in one place. Turn on autopay for each one. Then stop opening a new plan until the last is paid off.

And if you’re using pay-in-four to bridge a gap that keeps coming back every month, that’s the signal to stop splitting and start comparing. A fixed personal loan has a stated APR, which is the one thing a pay-in-four plan won’t give you. Run the payment through our loan calculator before you sign anything.

New York can argue about the ceiling until 2027. Your due dates are this month.
