What today's benchmark tells you
The Bank Prime Loan Rate shown above is a benchmark published in the Federal Reserve's H.15 release. It is useful context for borrowers because Prime is a common index used in variable-rate lending. It is not the same thing as an average HELOC rate, and it does not tell you what rate a lender will offer you.
The Consumer Financial Protection Bureau (CFPB) explains that HELOCs typically have variable interest rates. A variable rate generally has two parts: an index and a margin. Different lenders can use different indexes, so the first question to ask is which index your HELOC follows.
There is no single Federal Reserve table that tells us what every homeowner should be offered on a HELOC at a particular credit score. Lender pricing, borrower circumstances and loan terms vary. We would rather show you a verifiable benchmark and explain how to evaluate real lender offers than present false precision.
How HELOC rates are set
For a variable-rate HELOC, the lender's disclosures should explain the index used to make rate adjustments and how the annual percentage rate is determined. A common structure is:
| Component | What it means | Where to verify it |
|---|---|---|
| Index | A publicly available benchmark used by the plan, such as U.S. Prime or another index. | Your HELOC disclosures and the named index source |
| Margin | A percentage amount the lender may add to the index when calculating your rate. | Your lender's disclosures |
| APR / interest rate | The resulting rate under the terms of your agreement, including any applicable introductory pricing or adjustments. | Your lender's offer and account documents |
For example, if a plan used a 6.75% index and added a 0.75 percentage-point margin, the simple index-plus-margin calculation would be 7.50%. That is an illustration only; the 0.75% margin is not presented as a typical lender margin or a rate you should expect to receive.
How Prime connects to a HELOC
Prime is commonly discussed with HELOCs, but it is important not to oversimplify the relationship. The Federal Reserve's H.15 release reports the Bank Prime Loan Rate, while the CFPB notes that lenders may use different indexes in HELOC plans. Your contract identifies the index that actually controls your rate.
If your HELOC uses a variable rate, its rate can change according to the index and adjustment rules in your agreement. A Federal Reserve policy decision can influence market rates and Prime, but that does not mean every HELOC changes by the same amount on the same day.
Check the index, margin, introductory period, adjustment frequency, rate limitations and payment terms in the lender's disclosures. Those details determine how a benchmark change affects your particular HELOC.
What affects the rate you're offered?
There is no universal HELOC rate table based solely on credit score. Lenders set their own underwriting and pricing policies, and an offer can reflect several parts of your application and the HELOC itself.
- Credit profile: lenders can consider your credit history and other measures of creditworthiness.
- Home equity and requested credit line: the amount already owed against the property and the additional amount requested can affect the lender's risk assessment.
- Income and existing debts: lenders assess whether you can reasonably support the payments required by the plan.
- Product terms: the index, margin, introductory pricing, rate limits, draw rules and fixed-rate conversion features can differ from one product to another.
- Fees and discounts: lenders may charge different fees or offer discounts subject to specific conditions.
This is why comparing actual written offers is more useful than assuming a particular credit score guarantees a particular rate.
How to shop for a better HELOC deal
A lower advertised rate is not automatically the least expensive HELOC. Before applying, focus on the parts of the offer you can verify and compare.
- Review your credit reports. Check them for errors before applying and address inaccurate information through the appropriate credit-reporting process.
- Compare more than one lender. Ask for comparable information about the index, margin, APR, introductory rate, adjustment rules, fees and payment terms.
- Know your equity position. Lenders can have different requirements for how much equity must remain in the property after the HELOC is opened.
- Ask about fees and discounts. Do not assume a “no closing cost” or discounted-rate offer is free of conditions. Find out what triggers a fee, rate change or repayment obligation.
Variable rates and fixed-rate options
The CFPB says HELOCs usually have variable interest rates, which means payments may change. Some HELOCs allow some or all of an outstanding balance to be converted to a fixed interest rate. The availability, price and rules for that feature depend on the lender and plan.
| Feature | Variable-rate balance | Fixed-rate conversion, if offered |
|---|---|---|
| Rate movement | Can change according to the plan's index and adjustment rules | Converted balance uses the fixed terms stated by the lender |
| Payment predictability | Can change as the rate or balance changes | Can provide more predictable rate treatment for the converted amount |
| Availability | Common HELOC structure | Not available on every HELOC |
| What to check | Index, margin, adjustment frequency and rate limits | Conversion rate, fees, eligible balance and repayment terms |
What to compare across lenders
When comparing HELOC offers, read the disclosures rather than focusing only on the first rate you see. The CFPB notes that HELOC plans may involve a range of fees and transaction requirements.
- Index and margin — how the variable rate is calculated
- APR and introductory pricing — including when an introductory rate ends and how the later rate is determined
- Adjustment rules and rate limits — how often the rate can change and any applicable limitations
- Application and closing costs — which may include origination, appraisal, title or other charges
- Ongoing fees — such as annual, membership or inactivity fees when applicable
- Early cancellation terms — including any fee for terminating the HELOC early
- Draw requirements — minimum initial draws, transaction minimums or balance requirements if the plan has them
- Fixed-rate conversion — whether it is offered and whether a conversion fee or other conditions apply
Once you have a real rate quote, use our HELOC payment calculator to explore the potential payment at that rate. A calculator is an estimate, so compare its output with the lender's official disclosures before making a borrowing decision.
