Line of Credit for Bad Credit: What Actually Approves, and What It Costs
Here's the reality that reframes the whole question: unsecured personal lines of credit usually require strong credit, and borrowers with FICO scores below 670 tend to have fewer options — though exact minimums vary by lender. If your score sits in the "poor" range (300–579) or the low end of "fair," a traditional unsecured line isn't just hard to get — you're often shopping in a different market entirely, one where the collateral, the fees, and the fine print matter more than the headline rate.
That doesn't mean you're out of options. It means the smart move is knowing which product you're actually being offered, because borrowers searching for a line of credit are often shown a mix of true revolving lines, secured cards, installment loans, and high-cost short-term products. The gap between the best and worst of them can run into thousands of dollars on the same $5,000 balance.
Why "bad credit" changes the product, not just the price
Lenders sort borrowers into tiers, and those tiers are more rigid than most people assume. The widely used FICO bands break down like this: Poor 300–579, Fair 580–669, Good 670–739, Very Good 740–799, Exceptional 800–850. The 670 mark — the bottom of the "good" range — is where mainstream unsecured credit generally starts to open up, and a meaningful share of consumers score below it.
From a financial standpoint, the tier you land in doesn't just nudge your APR — it often determines whether a given product is available to you at all. A borrower at 720 and a borrower at 560 aren't looking at the same line with different rates; they're frequently looking at entirely different products with different structures.
Average APR, 24-month personal loan at commercial banks — Federal Reserve G.19, May 2026 (latest published)
What this means for you: That's not a line-of-credit average — it's a general unsecured-borrowing benchmark — but it shows how much cheaper mainstream credit can be for stronger-credit borrowers. That average is anchored by prime and near-prime applicants. If your credit is impaired, your quoted rate on any unsecured product will typically sit well above it; some bad-credit products can carry APRs in the high 20s or 30s, depending on the lender and product. The average is closer to the ceiling of what good credit pays than the floor of what damaged credit is offered.
This is where the math gets interesting. Take the same $5,000 repaid over three years: at that 11.86% benchmark it costs about $967 in interest, but at an illustrative subprime rate of 32% it costs roughly $2,840. That's a swing of nearly $1,900 driven entirely by which tier you're pricing into — the difference between a manageable cost of borrowing and a genuinely expensive one.
The options that actually approve with impaired credit
When a traditional unsecured line is off the table, five structures do most of the work for borrowers with thin or damaged credit. Each solves the lender's risk problem in a different way — and that's exactly why they approve where a standard line won't.
1. A secured personal line of credit
If a bank or credit union offers a savings- or CD-secured line, you pledge a cash deposit as collateral, and that collateral is what earns the approval. Because the lender's downside is covered, pricing can sit materially below unsecured bad-credit products — the deposit, not your score, is doing the underwriting. The trade-off is that your pledged cash stays locked up while the line is open, and starting limits are usually tied to the deposit amount.
2. A secured credit card, if a line isn't available
When a secured line is out of reach and the main goal is rebuilding, a secured card is the widely available fallback. The Consumer Financial Protection Bureau describes a secured credit card plainly: you put in an amount of cash, say $500, then you can spend up to that amount, and paying the bill restores your available credit. It's not a personal line of credit, but it's revolving, it's approvable with damaged credit, and — when the issuer reports to the bureaus — on-time payments build the history that reopens better options later.
3. A credit union, and Payday Alternative Loans as a fallback
Federal credit unions operate under a hard rate ceiling. The National Credit Union Administration caps most federal credit-union loans at 18% APR — a temporary ceiling now extended through September 10, 2027 — which makes a credit union a natural place to ask about a small line or card. If you can't qualify for a line, a Payday Alternative Loan (PAL) may be a lower-cost option for a small, one-time cash need. Note the distinction: a PAL is a closed-end installment loan, not a revolving line of credit. PAL I runs $200–$1,000 over one to six months; PAL II goes up to $2,000 over one to twelve months. Both cap at 28% APR, which can be lower than some high-cost bad-credit borrowing options. Some federal credit unions report PAL payments to the credit bureaus, which can help build payment history when payments are made on time — ask about the reporting policy before applying.
4. A co-signer or joint applicant
Adding someone with stronger credit can change your tier on paper. It also transfers real risk: the co-signer is fully on the hook, and any missed payment lands on both credit reports. It's a powerful lever — and a relationship you don't want to strain casually.
5. Home equity, if you're a homeowner
A HELOC is secured by your property, so credit standards can be more forgiving relative to the limit offered. The national average HELOC rate was 7.30% as of August 12, 2026, according to Bankrate — but that benchmark assumes a $30,000 line, a 700 FICO score, and an 80% combined loan-to-value ratio, so a borrower with damaged credit may receive a higher rate or be declined. The trade-off is serious either way: your home is the collateral. That's not a decision to make to cover a short-term cash gap.
Federal credit-union loan ceiling (most loans) — 18% — vs. the Payday Alternative Loan ceiling — 28%. NCUA, ceiling extended through Sept. 10, 2027.
What this means for you: If you can join a federal credit union you're eligible for, you're borrowing inside a regulated rate box. A PAL is a small installment loan rather than a line of credit, but its 28% cap can be lower than some high-cost bad-credit options — and when the credit union reports the account, on-time payments can help rebuild your profile over time.
The mistake that costs the most: carrying the balance too long
A line of credit isn't an installment loan. It's revolving, open-end credit: you draw what you need, you get a monthly bill, and you're charged interest on whatever balance you're carrying. There's no fixed "24-month versus 48-month" choice at signing. That flexibility is the appeal — and it's also the trap. With a revolving line, the danger isn't picking a long term at origination; it's keeping a high balance outstanding month after month.
This is where the math gets interesting. Take a $5,000 balance at a 24% APR and look at what your payoff pace does to the total cost:
The APR never changed — only how long the balance stayed alive. Stretching payoff from one year to two roughly doubles the interest, from about $674 to $1,345. Push the balance out further, or ride minimum payments, and the cost climbs from there. Because minimum payments are structured to barely outrun the interest clock, a balance carried that way can take years to clear and cost multiples of what a disciplined payoff would. On a revolving line, your payoff behavior matters more than a point or two on the rate.
On a revolving line, treat the minimum payment as a floor, not a target. Pay down the balance as aggressively as your budget allows — the total interest is driven by how long you carry the balance, not by a fixed term you chose up front.
Two more costs that are easy to miss. First, the APR on a line of credit is often variable: it's tied to an underlying index, so today's rate may not be the rate you pay later — if the index rises, so does your cost on the outstanding balance.
Second, fees. Some bad-credit lines carry cash-advance charges, monthly maintenance fees, or draw fees that don't show up in the APR you were quoted. Always ask whether the rate is fixed or variable, and request the full fee schedule before you commit; on smaller lines, fees can rival the interest.
Best move by borrower profile
Poor score (below ~580), nothing to pledge
Best move: Start with a credit union you're eligible to join, and ask about a small line, a secured card, or a PAL (a small installment loan) for a one-time need.
Why: The 18% and 28% NCUA ceilings keep pricing inside a regulated box, and credit unions may consider factors beyond the score, depending on their underwriting standards. If nothing approves, a secured card is the reliable fallback for rebuilding.
You can pledge a deposit or CD
Best move: A savings-secured line or secured card, ideally one that reports to all three bureaus.
Why: Collateral collapses the lender's risk, which is what can price a secured line materially below unsecured bad-credit products. You're typically paying far less to borrow — and building history at the same time, as long as the account reports to the bureaus.
You own a home with equity
Best move: Consider a HELOC only for a substantial, planned expense — not routine cash flow.
Why: Home-secured credit can offer higher limits and lower rates (the Bankrate national average was 7.30% as of August 12, 2026, for a strong-credit profile), but your house is the collateral. The cost of default is your home, so the use case has to justify that exposure.
Thin file — little history, not necessarily "bad"
Best move: A secured card or a credit-builder loan to establish a track record first.
Why: With a credit-builder loan, payments are reported as you go and you receive the saved funds at the end. Several months of consistent positive history can help strengthen a thin file, though the score impact and timing vary by borrower.
Secured line for bad credit: the trade-offs
Depends on your situation
Below 580, unsecured lines from major banks are unlikely, and pricing on what you can get tends to be steep. The most reliable routes are secured products and credit unions. A secured card or credit-builder loan won't hand you a large limit, but it starts the on-time payment history that moves your score upward — which is what unlocks better options later.
Then a secured line or card is often your strongest play. Pledging even a modest deposit typically earns a rate far below unsecured subprime pricing, and you keep the collateral as long as you pay as agreed. You're effectively renting your own money's creditworthiness — and it's usually among the lowest-cost approvals available with a damaged score.
It depends on how you'll use the money. A line gives you revolving, draw-as-needed access and you pay interest only on what you draw — useful for uneven or ongoing costs. A fixed installment loan gives you a set payment and a defined payoff date, which is usually cheaper and more disciplined for a single, known expense. For a comparison of the mechanics, see our personal loan guide.
A formal application usually triggers a hard inquiry, which can shave a few points temporarily. Worth noting: personal-credit hard inquiries generally do not get the rate-shopping deduplication that mortgage, auto, and student-loan inquiries receive, so spacing out applications matters more here. Many lenders offer a pre-qualification with only a soft pull — check for that before you formally apply.
A simple action plan
Let's be honest: the goal isn't just to qualify for something — it's to borrow at a cost that doesn't set you back further. Here's a sequence that tends to work:
1. Know your number first. Check your score and reports before you shop. Correcting an error or paying down a card to cut your utilization can move you across a tier line — and a single tier can reprice everything.
2. Try a credit union you're eligible to join. The 18% and 28% NCUA ceilings, plus underwriting that may look beyond the score, make this a natural first stop when your credit is below the "good" range.
3. If you have cash to pledge, go secured. A secured line or card usually beats unsecured subprime pricing by a wide margin and builds history at the same time.
4. Pre-qualify with a soft pull before any hard application. See real numbers without the inquiry, then compare the APR, whether it's fixed or variable, and the full fee schedule across offers.
5. On a line, pay the balance down fast. The cost is driven by how long you carry the balance, so treat the minimum as a floor, not a target. Run your own numbers with our loan calculator before you commit.

The bottom line
With bad credit, the winning move is usually to change the structure, not just accept a worse rate: pledge collateral or borrow through a rate-capped credit union, and you can often cut your cost of borrowing substantially. Then check whether the APR is fixed or variable, pay any balance down as fast as your budget allows, and treat on-time payments as the tool that reopens the mainstream market.

Unsecured personal lines usually require strong credit, and exact minimums vary by lender — many reserve their best pricing for higher-tier borrowers, and applicants below the "good" range (670) tend to have fewer options. Below that, secured lines, credit-union products, or a co-signer are the usual paths.
Possibly, but options narrow and pricing rises. Secured cards and lines are the most dependable at that level, and some online lenders and credit unions work with lower scores — often at higher rates. Compare offers carefully and check the full fee schedule.
It can, as long as the issuer reports your payments to the three nationwide credit bureaus. On-time payments are what build the history; a deposit alone doesn't. Confirm the reporting policy before you open the account.
For most people rebuilding, a secured credit card is the simpler, more widely available starting point. A personal line of credit can offer larger draws, but tends to have stricter approval and more fees. The right choice depends on how much you need and how you'll use it.
Often variable. A personal line of credit's APR is frequently tied to an underlying index, which means the rate — and your cost on any outstanding balance — can move over time. Today's rate may not be the rate you pay later. Always ask whether the APR is fixed or variable before you open the line.
A line of credit is revolving — you draw what you need, up to a limit, and pay interest only on the drawn balance. A loan gives you a lump sum with a fixed repayment schedule. Lines offer flexibility for uneven or ongoing needs; a fixed installment loan gives you a defined payoff date, which can be easier to budget for a single, known expense.
