What is a personal line of credit?
A personal line of credit (PLOC) is a revolving loan with a set credit limit from which you can borrow, repay, and borrow again — paying interest only on what you use. It works like a credit card but typically has lower rates and deposits directly to your bank account.
The full picture
How a personal line of credit works
A personal line of credit gives you access to a pool of funds up to your approved limit. You draw from it when you need cash — typically via bank transfer or a linked account — and only pay interest on the outstanding balance. As you repay, your available credit replenishes. This revolving structure makes it fundamentally different from a personal loan, which delivers a lump sum upfront and requires fixed payments from day one.
Secured vs. unsecured personal lines of credit
Unsecured personal line of credit: No collateral required. Approval depends on creditworthiness — most traditional lenders require 670+ FICO and documented income. Limits typically range $5,000–$50,000 at 8–24% APR. Best for borrowers with good-to-excellent credit who need flexible access to funds.
Secured personal line of credit: Backed by collateral — commonly a savings account, CD, vehicle, or home equity. Because the lender's risk is offset, approval is more accessible for borrowers with bad or fair credit. A home equity line of credit (HELOC) is the most common secured consumer line — it uses your home's equity as collateral and typically offers the lowest rates (often prime + 0.5–2%). The trade-off: your home is at risk if you default.
Personal line of credit vs. personal loan
- Structure: Line of credit is revolving (draw/repay/redraw); personal loan is installment (lump sum, fixed payments).
- Interest: PLOC charges interest only on drawn balance; personal loan charges interest on full amount from day one.
- Flexibility: PLOC is better for ongoing or unpredictable expenses; personal loan is better for one-time fixed-amount needs.
- Rate structure: Personal loans typically have fixed rates; PLOCs typically have variable rates tied to prime.
- Availability: Personal loans are available from more lenders (including online); PLOCs are mainly offered by banks and credit unions.
When a personal line of credit is the right choice
PLOCs work best when your funding need is recurring or uncertain in size — home repairs, seasonal expenses, or a business cash-flow bridge. For small business owners, a business line of credit often serves this purpose better, since it's underwritten on business cash flow rather than personal credit.

Worked example — personal line vs. personal loan
You need up to $10,000 for home repairs over 6 months but aren't sure of the exact amount. A $10,000 personal loan charges interest on $10,000 from day one. A $10,000 personal line of credit lets you draw $3,000 in month 1 and pay interest only on $3,000 — then draw more as work proceeds. Over 6 months drawing an average of $6,000, the PLOC saves roughly 40% in interest vs. the personal loan.

Key takeaways
- A personal line of credit is a revolving loan — draw, repay, redraw — paying interest only on outstanding balances.
- Unsecured PLOCs require 670+ FICO; secured PLOCs (backed by savings, home equity, etc.) are accessible to bad/fair credit borrowers.
- PLOCs are better than personal loans for unpredictable or recurring expenses; personal loans are better for fixed one-time needs.
- HELOCs offer the lowest rates but put your home at risk — only appropriate for disciplined borrowers with clear repayment plans.
- Small business owners: a business line of credit underwritten on business revenue is usually more accessible and appropriate than a personal PLOC.
