Affiliate disclosure: One first-party hop may appear. Commission does not change APR or fees.
The pitch is always the same: replace a 24% APR card with a lower installment and cut the payment in half. Payment is not cost. A longer term hides interest. An origination fee hides a smaller amount financed. This page is the arithmetic we ran on 12 September 2026 in 19 min, using labeled examples — not live offers.
Why the payment lie works
A $10,000 revolving balance at 24% APR with a 2% minimum payment can sit for years. An installment at 14.5% APR over 36 months looks cheaper per month and actually cheaper in total interest if you qualify for that 14.5% and if origination is near $0. A 635 FICO file that is quoted 28.5% APR plus a 6% origination fee can pay more than the card.
Labeled $10,000, 36-month worksheet
| File in the example | Installment APR | Origination | Cash received | What the worksheet says versus a 24% card |
|---|---|---|---|---|
| Prime illustration (730 FICO) | 14.5% | 0% | $10,000 | Interest in the worksheet is lower than keeping 24% if you actually amortize |
| Near-prime illustration | 18%–22.5% | 3%–5% | Less than $10,000 | Fee can erase the APR gap |
| Subprime illustration (635 FICO) | 28.5% | 6% ($600) | $9,400 | You still repay $10,000 plus a higher finance charge |
Subprime cash math: $10,000 note, $600 taken at origination, $9,400 in the account. Monthly payment in the 28.5% / 36-month worksheet is not a hardship program. If the card issuer will freeze interest near 6%–9% for 48–60 months, that call is often cheaper than originating a 28.5% installment. We did not verify any issuer hardship desk on this date; call yours and get the term in writing.
Card installments versus a new loan
Chase Pay Over Time, Amex Plan It, and similar issuer plans split an existing purchase. They usually skip a new hard pull. They are not cash. BNPL apps sitting beside the card are a third stack; CFPB has treated some of that stack as credit that needs TILA-style disclosure. Juggling four BNPL plans plus a card minimum is how extra debt shows up on a cash-flow sheet even when the FICO file still looks clean.
Five checks before you originate
- Read the FICO variant your lender will buy, not only a VantageScore dashboard.
- Add origination to the finance charge. A 5% fee on $10,000 is $500 off the top.
- Price a 0% transfer card only if the transfer fee and the payoff calendar are written.
- Ask the current issuer for a hardship plan before you take a 28%+ installment.
- If you originate, stop recharging the old cards. An installment plus new revolving spend is two debts.
Cons / limitations
- Origination fees shrink amount financed while you still repay the note amount.
- Files below roughly 660 FICO are often quoted 23%–36% APR on unsecured installment paper; that is not automatically cheaper than 24% revolving.
- Fixed drafts do not flex when hours get cut; card minimums do, at a brutal interest cost.
- Hardship programs and 0% transfers are issuer-specific. This page is not your issuer.

How to recompute the $10,000 row yourself
Payment on a fixed installment is P = r(1+r)^n / ((1+r)^n − 1) times principal, where r is monthly rate and n is months. For 14.5% APR, r = 0.145/12. For 36 months that is the prime illustration. Add origination to cash cost: if $500 is deducted, your cash-in-hand is $9,500 and the formula still uses $10,000 if that is the note amount. Finance charge is (payment × n) − amount financed, with amount financed defined by the TILA box, not by the marketing banner.
For the card, do not use that installment formula unless you will actually pay a fixed amount that amortizes in 36 months. A 2% minimum on $10,000 is $200 and does not amortize like $341.73. Run the card at the payment you will really make. If that payment is $200, the 24% revolving remainder after 36 months is still large. That remainder is the number the half-the-payment pitch hides.

Minimum-payment remainder
A 2% minimum on $10,000 is $200. At 24% APR, most of that $200 is interest at the start. After 36 months of $200 payments you still owe a large remainder. The installment worksheet at $341.73 is a different contract: it is designed to hit $0. Comparing $200 to $341.73 as if both finish in 36 months is the error. Re-run the card at $341.73 if that is the payment you will actually make; then the comparison is honest. If you will only pay $200, the installment is a budget change, not a gift.
