What the 6% Cap Actually Covers on a Card or Credit Line

Here is a question almost no SCRA guide answers, and it decides how much money the cap is actually worth to you.

You have a credit card you opened two years before you enlisted. You invoke the 6% cap on day one. Then, in month four of your enlistment, you put $800 of car repairs on that same card.

Is that $800 at 6%, or at 24%?

The honest answer is that the law and your bank disagree, and the disagreement is in your favor.

What the statute says: the balance, not the account

Section 3937 caps an obligation “incurred by a servicemember… before the servicemember enters military service.” The word “incurred” is not defined anywhere in the SCRA, and the statute says nothing at all about open-end credit, draws, or advances. That silence is the whole problem.

Regulators have filled it, and they have filled it against you. The OCC’s examiner handbook poses your exact scenario as a worked example:

Example 4: Credit Card. A servicemember has a credit card with a $1,000 charged debt before active duty. After going on active duty, he or she charges another $2,000 in credit card charges. Question: Is the servicemember entitled to the interest rate reduction for charges incurred after going on active-duty military service? Answer: Only the $1,000 (debt charged before active duty) of the total $3,000 debt qualifies for the interest rate reduction to 6 percent.

The CFPB says the same: “new charges made on a revolving credit agreement” that originated during active duty “are not eligible for the interest rate reduction.”

So by the letter of the law, your pre-service card is a frozen snapshot. The balance on your start date is protected. Everything you spend from that day forward rides at the full contract rate, and your $800 in car repairs is at 24%.

The reasoning, from the Fourth Circuit in Sibert v. Wells Fargo (construing a neighboring section with identical “before… military service” language): Congress protected pre-service obligations because entry into the military could “unexpectedly” upend them. It declined to protect during-service obligations “because both the servicemembers and lenders would be aware of the servicemember’s income and military status.” You knew you were a soldier when you swiped. So did they.

What your bank actually does: the account, not the balance

Now go read the issuers’ own pages, and something better happens.

American Express states it provides SCRA relief “on accounts that were opened before the start of the servicemember’s active duty period.” Not balances. Accounts.

Navy Federal lists what qualifies (consumer loans, credit cards, checking lines of credit, student loans, business loans, mortgages) and conditions all of it on whether “you opened them before you started Active Duty.”

Capital One frames eligibility the same way.

The reason is not generosity, it is operations. Carving a single revolving account into a protected pre-service tranche and an unprotected post-service tranche, tracking both for years across statement cycles and payments and payment-allocation rules, for every servicemember, is a compliance nightmare that would generate errors, and errors under the SCRA get you a DOJ consent order. Applying one rate to the whole line is trivial and impossible to get wrong.

So they do the easy thing, and the easy thing is worth real money to you.

Why this is the most valuable line in the whole SCRA

Put the two halves together.

If your issuer applies the statutory minimum, your pre-service card is a one-time benefit on a fixed balance. Cap it, then stop using the card, because every new charge is uncapped anyway.

If your issuer keys to the account-open date, that card is a 6% (or 4%) line of credit for your entire enlistment. Everything you charge in uniform lands at the reduced rate. That is not a snapshot. That is an ongoing facility, at a rate no civilian card in America offers.

For a four-year enlistment with even modest revolving use, the account-open-date issuer is worth several times more than the two points of rate that everyone shops for.

Which means the question you should be asking your lender is not “what rate do you apply.” It is this, in writing:

Does your SCRA benefit apply to the entire account if the account was opened before my active-duty start date, or only to the balance outstanding on that date?

Almost nobody asks it. The answer is worth more than the rate.

One caution: this is voluntary. No statute compels the account-open-date approach, and the OCC’s own guidance points the other way. An issuer can change it. Get the answer in writing and keep it. And note that even Navy Federal’s page contains both tests, saying accounts are eligible if “opened” before active duty, while also saying “debts incurred after your Active Duty start date are not covered.” Those two sentences do not agree with each other, which tells you how unsettled the ground is even inside the banks.

The HELOC question, which nobody has answered

Now the harder version. You opened a home equity line of credit before you entered service. During your deployment, you draw $40,000 against it.

Is the draw at 6% or at 9%?

There is no answer. No case law. No regulation. No DOJ enforcement position. We searched the federal opinion corpus; the SCRA appears in hundreds of opinions and not one addresses a revolving draw under § 3937. This is genuinely open ground, and any source that tells you otherwise with confidence is guessing.

Here is what each side actually has.

The regulators say the draw is unprotected. The OCC’s flow chart is blunt: “SCRA does not apply to loans or advances made after active duty begins… credit card or home equity line of credit advances made during active duty are no longer protected by SCRA.” That is examiner guidance, not law, but it is what your bank’s compliance department reads, so it is what your bank will do.

The text has a real argument the other way, and it is stronger than the regulators acknowledge:

1. The statute says “obligation or liability,” not “advance.” Congress used the word “advance” nowhere in § 3937. It knew the word. It chose a different one.
2. A HELOC is a binding commitment. Unlike a credit card, where the issuer can cut your line at will, during the draw period the lender is contractually obligated to fund your draws. You incurred the liability, and the lender incurred its duty to lend, when the note was signed. A draw is performance under a pre-service contract, not the striking of a new bargain.
3. § 3937(d)(2) is textual ammunition. It defines “obligation or liability” to expressly include “a mortgage, trust deed, or other security in the nature of a mortgage.” A HELOC is secured by exactly that, executed pre-service. If the mortgage is the obligation, the obligation is pre-service in its entirety, and it would pull the whole thing into § 3937(a)(1)(A)‘s cap for service plus one year.

Nobody has run that argument in court. It might win.

And one oddity worth knowing, because it may be used against you: the OCC’s flow chart gates lines of credit on a three-part test found nowhere in the statute. It asks whether the line was “entered into, drawn on, and at least 1 payment made, before the servicemember was assigned to active-duty military service.” So on OCC’s view, a pre-service HELOC you had not yet drawn on, or had drawn but not yet made a payment on, gets nothing at all. There is no statutory basis for that requirement and the OCC does not explain it. If a lender cites it at you, know that it is an examiner gloss, not law.

What to actually do

Assume the conservative rule and be pleasantly surprised. Plan as though only your pre-service balance is capped, and as though draws during service are not. Then ask your issuer, in writing, whether it does better. Most will.

Open credit lines before your start date, not after. If you are going to have a card or a line at all, having it before the line is strictly better. An account opened during service gets no SCRA cap, only the MLA’s 36% ceiling, which is a floor against predators, not a benefit. And a pre-service account is the one that might behave like a capped line for your whole enlistment. This is one piece of the broader pre-service window.

Do not draw a large HELOC advance during service assuming it is capped. You may be right, and you have a real argument, but you would be betting a large sum on an open question with the regulators against you. If you need the money and you can see the line coming, draw it before you report, when the answer is not in doubt.

Watch the fees. Section 3937(d)(1) folds “service charges, renewal charges, fees, or any other charges (except bona fide insurance)” into the definition of interest. On a covered pre-service line, that means annual fees, late fees, and arguably per-item overdraft fees all count against the 6% all-in cap. Amex explicitly treats its annual membership fee that way. Most people never think to check the fee side, and on a premium card the fee is worth more than the rate.

The law behind this: 50 U.S.C. § 3937(d)

Definitions: 'interest' includes service charges, renewal charges, fees, and any other charges; 'obligation or liability' includes a mortgage or other security in the nature of a mortgage: read the statute.
