A HELOC rate by credit score is the interest rate a lender charges on a home equity line of credit, and it is heavily tied to your FICO score: higher scores typically unlock lower rates, while lower scores usually mean higher rates or outright denial. Because a HELOC is secured by your home equity, lenders price it partly on how risky you look, and your credit score is one of the clearest risk signals they have. This guide explains how credit scores shape HELOC rates, what tiers generally look like, and how to strengthen your application.

Why credit score drives your HELOC interest rate

When you apply for a HELOC, a lender reviews your credit score, income, existing debts, and the amount of equity you have. Credit score matters because it summarizes your history of managing borrowed money. A high score suggests you pay on time and use credit responsibly, so the lender may offer a lower interest rate. A lower score suggests more risk, so the lender may charge a higher rate, require a larger equity cushion, or decline the application.

Your HELOC rate is usually variable and tied to a benchmark index plus a margin. The margin is where your credit score does most of its work. Two applicants with the same home and loan-to-value can receive different margins purely because of their credit profiles. That is why comparing offers from several lenders is worthwhile: pricing models differ, and a score that is mid-tier at one lender might be top-tier at another.

Typical HELOC rate patterns by credit score tier

Exact rates change with market conditions, so no table can promise a specific number. However, the general pattern below is widely observed across the lending market. Treat it as directional guidance, not a quote.

These ranges are general and vary by lender, property type, occupancy, and loan-to-value. A borrower with a 680 score and 40% equity may receive a better offer than a borrower with a 720 score and 95% combined loan-to-value, because equity and loan-to-value also influence pricing.

How lenders combine score, equity, and loan-to-value

Credit score is not the only lever. Lenders look at your combined loan-to-value, which compares all mortgage debt plus the new HELOC against your home's appraised value. Lower loan-to-value generally means lower risk for the lender and can offset a modest credit score. Strong, documented income and stable employment also help. If your score is on the lower end, increasing your equity stake or paying down other debts before applying can improve your terms.

Some lenders also let you choose between a HELOC and a cash-out refinance. A refinance replaces your existing mortgage and may offer a fixed rate, while a HELOC keeps your first mortgage in place and adds a second lien. If you only need part of your equity and want flexibility to draw funds over time, a HELOC often fits better. If you want one predictable payment and a fixed rate, a refinance may be the stronger fit.

Ways to improve your rate before you apply

• Check your credit reports for errors and dispute inaccuracies before a lender pulls your file.
• Pay down revolving balances to lower credit utilization, which often lifts scores within a few reporting cycles.
• Avoid opening new credit accounts in the months before applying, since new inquiries and accounts can lower scores.
• Make every payment on time; payment history is the largest scoring factor.
• Build more home equity by paying down your mortgage principal or waiting for property values to rise.
• Compare offers from multiple lenders, because margins and fees vary meaningfully.

What else affects your HELOC cost

Beyond credit score, your rate and total cost depend on the benchmark index, the margin, introductory periods, annual fees, closing costs, and whether the line has a draw period followed by repayment. Some HELOCs offer a promotional rate for an initial period, then adjust. Read the terms carefully so you understand how your payment can change. A slightly higher rate with low fees can cost less overall than a lower rate with expensive closing costs.
