The legal difference from a credit card is one element, and it is the element everybody notices without naming. 12 CFR 1026.2(a)(20) defines open-end credit as credit extended under a plan in which the creditor "reasonably contemplates repeated transactions," may impose a finance charge "from time to time on an outstanding unpaid balance," and, third, in which "the amount of credit that may be extended to the consumer during the term of the plan (up to any limit set by the creditor) is generally made available to the extent that any outstanding balance is repaid." That third test is the one that matters here. Repaying a revolving balance restores the ability to borrow it again; repaying a closed-end loan does not, because there is no plan to draw on. The familiar observation that an installment loan ends because it is designed to end is therefore a legal property rather than a statement about willpower, and it is the strongest argument for the product.
Unsecured has a specific consequence, and it is what is given up when the same balance is moved onto collateral. Because no property is pledged, a lender that is not paid has no asset to take. Its remedies are collection activity and, if it sues and prevails, a judgment, which it may then attempt to enforce by whatever means state law allows. And an unsecured personal loan is dischargeable in bankruptcy in the ordinary way, unlike the categories that survive discharge. Those are real protections with a price attached, which is that unsecured credit is dearer than secured credit for exactly the same borrower. A reader considering moving a personal loan balance onto home equity to save a few points is trading those protections for the saving, and that is the comparison rather than the rate alone.
The origination fee and the APR, stated through the mechanism rather than as advice. Many personal loans carry an origination fee taken out of the advance, so a borrower who signs for a stated sum receives less than that while owing the whole figure. Regulation Z handles this precisely. 12 CFR 1026.18(b) requires the disclosed amount financed to be calculated by taking the principal loan amount, adding other financed amounts, and "subtracting any prepaid finance charge," and 1026.2(a)(23) defines a prepaid finance charge as any finance charge "paid separately in cash or by check before or at consummation of a transaction, or withheld from the proceeds of the credit at any time." That second limb is the one that catches an origination fee, since such a fee is not paid over separately but taken out of the advance. A fee deducted at closing therefore reduces the amount financed while leaving the payments untouched, and the APR is computed against that smaller figure. That is the arithmetic reason the APR on a fee-bearing loan sits above its interest rate, and the reason two loans quoting the same rate are not the same loan. On closed-end credit the APR is doing the work it was designed for, which is not true of a credit card APR.
Two federal rights that read as courtesies and are not. 15 USC 1615(a)(1) provides that "if a consumer prepays in full the financed amount under any consumer credit transaction, the creditor shall promptly refund any unearned portion of the interest charge to the consumer," subject only to a de minimis exception where the refund would be under a dollar. And 12 CFR 1026.18(k) requires the disclosure itself to answer the prepayment question before you sign, in one of two forms depending on how the loan is built: where the finance charge is computed by applying a rate to the unpaid balance, a statement of "whether or not a charge may be imposed for paying all or part of a loan's principal balance before the date on which the principal is due"; where the finance charge is computed some other way, meaning a precomputed loan, a statement of "whether or not the consumer is entitled to a rebate of any finance charge if the obligation is prepaid." Which limb appears on your paperwork tells you which kind of loan you have, which is worth knowing because it decides whether paying early saves anything.
One limit on a third right, which is easy to state more broadly than the statute does. 15 USC 1615(c) entitles a consumer to a free payoff statement once a year, delivered within five days of request, but on its own terms it applies to a precomputed consumer credit account. On an ordinary simple-interest personal loan the payoff figure is the outstanding principal plus interest accrued to the date, which servicers supply as a matter of course, but the five-day statutory right is not the source of it.
Variants exist and they answer different questions. A share-secured or credit-builder loan is aimed at a thin credit file rather than at a need for cash, and the material on the credit and debt guide sets out how each works. A loan against a workplace retirement plan is a different instrument with a different risk, covered by the published material on 401(k) loans. And the high-cost end of the market, payday and title lending, is not a personal loan in the sense described here.
