HELOC rates don't have a single number — they're built from two parts: the prime rate, which moves with Federal Reserve decisions, and a fixed margin your lender sets based on your credit profile. With prime holding at 7.50% in May 2026, most homeowners are paying between 8.00% and 10.50% on outstanding balances. That 2.5-percentage-point spread translates to a difference of more than $200 per month on a $100,000 balance — a meaningful gap that depends almost entirely on your credit score.

Current HELOC Interest Rates in 2026: What Borrowers Are Actually Paying
The prime rate — set by U.S. banks and tied directly to Federal Reserve policy — is 7.50% as of May 2026. Every HELOC is priced as prime rate + lender margin, so that 7.50% is the baseline. Your margin is negotiated at origination and stays fixed for the life of the line; what moves is the prime rate underneath it.
According to the Federal Reserve (H.15 Selected Interest Rates, 2026), the prime rate has remained at 7.50% since late 2025. Here is how that translates to real HELOC APRs across credit score tiers:
HELOC Interest Rate by Credit Score — May 2026 (Prime Rate: 7.50%)
| Credit Score | Lender Margin (above prime) | Typical HELOC APR |
|---|---|---|
| 760 and above | +0.50% to +0.75% | 8.00%–8.25% |
| 720–759 | +1.00% to +1.50% | 8.50%–9.00% |
| 680–719 | +1.75% to +2.25% | 9.25%–9.75% |
| 640–679 | +2.50% to +3.00% | 10.00%–10.50% |
| Below 640 | Typically ineligible | — |

The practical takeaway: improving your credit score from 680 to 760 before opening a HELOC saves approximately 1.50 percentage points — that's $125 per month on a $100,000 balance, or $1,500 per year over the life of the draw period.
How HELOC Rates Are Set: Prime Rate Plus Your Margin
Your HELOC APR has two components, and only one of them moves. The prime rate — currently 7.50% — resets whenever the Federal Reserve adjusts its benchmark federal funds rate. Your margin is locked in at origination and never changes, regardless of what happens with rates afterward.
Here is how the math works in practice:
- 760+ credit score: Prime 7.50% + margin 0.75% = 8.25% APR → $688/month on a $100,000 balance (interest-only draw period)
- 720–759 credit score: Prime 7.50% + margin 1.25% = 8.75% APR → $729/month on a $100,000 balance
- 680–719 credit score: Prime 7.50% + margin 2.00% = 9.50% APR → $792/month on a $100,000 balance
Because the margin is negotiable before you sign, getting quotes from at least three lenders matters more with HELOCs than with most loan products. A credit union may offer prime + 0.50%, while a large bank charges prime + 1.50% on the same borrower profile — a difference of $83 per month on a $100,000 balance before a single Fed move happens.
HELOC Rate vs. Home Equity Loan Rate in 2026: Which Costs Less?
Both products tap your home equity, but they price risk differently. A HELOC offers a variable rate starting as low as 8.00% in May 2026. A fixed-rate home equity loan currently runs 8.50%–9.50% for most borrowers — higher upfront, but immune to future rate increases.
Choosing between them comes down to two questions: how much do you need now, and which direction do you think rates are heading?
- HELOC wins if: You need funds in stages (renovation, tuition), the Fed is likely to cut rates, or you plan to pay down the balance quickly during the draw period
- Home equity loan wins if: You need the full amount upfront, you want certainty in your monthly payment, or you believe rates will rise further

For a borrower drawing $100,000 in a flat or declining rate environment, the HELOC saves roughly $50–$100 per month compared to a fixed home equity loan — savings that compound meaningfully over a 10-year draw period.
What Most Homeowners Get Wrong About HELOC Interest Rates
The most common mistake is not understanding that a HELOC rate is variable in both directions. Most borrowers focus on today's rate and assume it stays there. It won't. If the Federal Reserve cuts rates 0.50% — two quarter-point reductions — a $100,000 HELOC payment drops by $42 per month. If rates rise 0.50%, the same payment increases by $42.
The larger mistake is signing without comparing margins. Two lenders quoting "prime plus" sound identical until you read the fine print. A margin difference of 2.00 percentage points — prime + 0.75% versus prime + 2.75% — costs $167 per month on a $100,000 balance, every single month, for the entire draw period. That's $20,040 over 10 years on the same loan amount, with the same home and the same credit score.
Before signing any HELOC agreement, request the margin in writing, confirm whether the lender offers a rate cap (maximum rate your APR can reach over the life of the line), and get at least three competing offers. Most lenders will negotiate the margin by 0.25%–0.50% for well-qualified borrowers who mention they are comparing offers.
Frequently Asked Questions
What is the current HELOC interest rate in May 2026?
As of May 2026, with the prime rate at 7.50%, typical HELOC APRs range from 8.00% to 10.50% depending on your credit score and lender. Borrowers with scores of 760 or above are seeing rates near 8.00%–8.25% at major banks and credit unions. Borrowers with scores in the 640–679 range typically receive rates of 10.00%–10.50%.
Is a HELOC interest rate fixed or variable?
HELOC rates are almost always variable, tied to the prime rate, which moves with Federal Reserve decisions. When the Fed changes its benchmark rate, your HELOC APR adjusts within one to two billing cycles — typically 30 to 60 days. Some lenders offer fixed-rate conversion options during the repayment period, but the draw period rate is nearly always variable.
Can I negotiate a lower HELOC interest rate?
Yes — specifically the margin, which is the fixed percentage your lender adds above prime. Margins are negotiable before you sign, and credit unions and community banks are generally more flexible than large banks. Requesting a 0.25%–0.50% margin reduction is common and realistic for borrowers with strong credit, and saves $250–$500 per year on a $100,000 balance.
Will HELOC rates go down in 2026?
HELOC rates will fall if the Federal Reserve cuts the federal funds rate, which directly lowers the prime rate. As of May 2026, market expectations point to one or two 0.25% cuts possible later in the year. Each 0.25% cut would reduce a $100,000 HELOC payment by approximately $21 per month, and would take effect within one to two billing cycles after the Fed announcement.
In May 2026, the current HELOC interest rate for most borrowers falls between 8.00% and 10.50% APR, built on a prime rate of 7.50% plus your lender's margin. Your credit score is the single largest variable within your control — improving from 680 to 760 saves over $1,500 per year on a $100,000 balance. Compare at least three lenders before signing and always negotiate the margin. Find your exact monthly HELOC payment with our free HELOC Rate Calculator.
