The short answer
A business HELOC and a business line of credit are both revolving lines: you draw what you need, pay interest only on the balance, and reuse the line as you repay. The difference that drives everything is collateral. A HELOC is secured by your home, which makes it cheaper but means your home is at risk. A business line of credit is secured by the business (or unsecured with a personal guarantee), which is faster and keeps your home out of it, at a higher rate.
So the choice is mostly about three things: cost, speed, and how much risk you want to put on your personal home. If you have real home equity, strong credit, and time to close, the HELOC's lower rate is hard to beat. If you need capital in days, don't have much equity, or simply don't want your house on the line, the business line of credit is the better tool even though it costs more.
What each one is
A business line of credit is a revolving facility set up against your business. A lender approves a limit, you draw and repay as cash flow moves, and you pay interest only on what you have drawn. Bank lines are cheaper and slower; online lines are faster and more expensive and accept weaker profiles. For the full mechanics, see our business line of credit guide.
A HELOC is the same revolving structure, but the collateral is the equity in your home rather than your business. Because a home is strong collateral, the rate is typically much lower, but the loan involves a home appraisal and mortgage-style underwriting, and your home secures the debt. The business version simply means the funds are used for a business purpose.
In other words, these are close cousins that behave the same day to day. The whole decision comes down to what secures the line and what that does to your cost, speed, and risk.
Cost: the HELOC usually wins
Because a HELOC is secured by real estate, it is usually the cheaper of the two. HELOC rates are commonly priced off the prime rate, while business lines of credit, especially fast online ones, price higher once fees are included (illustrative ranges, not quotes; your rate depends on credit, equity, revenue, and lender).
That cost gap is the HELOC's main appeal. On a balance you carry for months, the difference between a home-equity rate and an online-line rate can be substantial. If minimizing cost is the priority and you have the equity, the HELOC is the natural choice.
One caveat: HELOC rates are usually variable and move with the prime rate, so budget for the possibility that the payment rises. A line of credit can be variable too, so compare the actual structure of each offer, not just the headline rate. As always, compare total dollar cost, not just the rate.
Speed and qualification
This is where the line of credit wins. An online business line of credit can be approved in days, sometimes faster, on the strength of your bank-statement cash flow. A bank line takes longer, often one to several weeks. Either way, no home appraisal is involved.
A HELOC is slower because it is real-estate-secured. Expect a home appraisal, title work, and mortgage-style documentation, which typically pushes closing out to a few weeks. If your need is urgent, that timeline alone can settle the decision.
On qualification, a business line of credit leans on your business revenue and credit; a HELOC leans on your home equity and personal credit, generally wanting stronger personal credit because it is secured by a dwelling. If your business is strong but you have little home equity, the line of credit is the realistic option; if your business is thin-file but you have significant equity and good personal credit, the HELOC may unlock more.
The risk difference that matters most
This is the part no honest comparison can skip. A business line of credit puts the business at risk. A business HELOC puts your home at risk. Same revolving convenience, very different downside.
If a business line of credit goes bad, the consequences are serious but contained to the business and your personal guarantee. If a HELOC goes bad and you cannot cover the payments, you can lose your house. That is the price of the lower rate, and it should weigh heavily for any owner whose family home is the collateral.
The practical takeaway: reserve the HELOC for productive, predictable uses you are confident you can service, and lean on the business line of credit when the need is uncertain, short-lived, or speculative, so a bad outcome doesn't reach your home.
Which to choose, and why not both
Choose the HELOC when you have meaningful home equity, strong personal credit, time to close, and a clear, productive use of funds, and you want the lowest available cost. Choose the business line of credit when you need speed, want to keep your home out of it, don't have much equity, or your strength is business revenue rather than home value.
Many owners don't choose at all: they keep a business line of credit for fast, everyday flexibility and use a HELOC for larger, cheaper draws, or layer both into a broader structure.
