How HELOC Rates Work in 2026
HELOC rates are variable and tied to the prime rate. Understanding the rate formula helps you evaluate offers and anticipate payment changes.
Current Rate Snapshot

Current Prime Rate

Typical Margin Range
-0.5% to +2%
Prime rate is 7.00%, effective September 17 2026, after the Federal Reserve raised the federal funds rate on September 16 2026. Bankrate's last national HELOC survey (week of September 9 2026) showed 7.26% at the prior 6.75% prime; applying that same margin to the new prime puts the current average near 7.5%. Your actual rate is prime plus your lender's margin.

The prime rate is set by banks following Federal Reserve decisions. The margin is set by your lender based on your credit profile. Together they determine your HELOC rate.
Rate Components Explained
Prime Rate
The benchmark rate published by major banks, typically 3% above the federal funds rate. When the Fed raises or lowers its target rate, the prime rate moves in lockstep. As of September 17 2026, the prime rate is 7.00%.
Lender Margin
The amount your lender adds to (or sometimes subtracts from) the prime rate. Margins typically range from -0.5% to +2% depending on your credit score, LTV, and the lender's competitiveness. A lower margin means a lower rate.
APR (Annual Percentage Rate)
Your total annual rate, which is the prime rate plus your margin. For HELOCs without closing costs, the APR equals the interest rate. If there are closing costs, the APR may be slightly higher to reflect the true borrowing cost.
Rate Caps
Most HELOCs have a lifetime cap (often 18%, though some lenders such as Bank of America cap at 24%) and may have periodic adjustment caps. The lifetime cap sets the maximum your rate can ever reach. Some lenders also offer a rate floor, meaning your rate cannot drop below a certain level.
Introductory Rates
Some lenders offer a discounted rate for the first 6 to 12 months. These intro rates can be 1% to 2% below the standard rate. After the intro period, the rate adjusts to prime plus your margin. Factor this into your total cost calculation.
Fixed-Rate Conversion
Many HELOCs now offer the option to convert some or all of your balance to a fixed rate. The fixed rate is typically 0.5% to 1.5% higher than the variable rate but provides payment stability. This is a hedge against rising rates.
What Affects Your Rate
| Factor | Impact | Detail |
|---|---|---|
| Credit Score | High | 760+ gets best rates. Each 20-point drop may add 0.25% to 0.5% to your margin. |
| Combined LTV | High | Lower LTV (more equity) = lower risk = better rate. Below 60% CLTV gets the best pricing. |
| Loan Amount | Medium | Some lenders offer rate discounts for larger credit lines ($100K+). Smaller lines may carry higher margins. |
| Relationship Discount | Medium | Auto-pay from the lender's checking account typically saves 0.25% to 0.50%. Existing customers may get additional discounts. |
| DTI Ratio | Low-Medium | Higher DTI may result in a higher margin or lower credit limit. Below 36% DTI is ideal. |

How to Get the Best HELOC Rate
Improve Your Credit Score
Pay down existing debt, correct errors on your credit report, and avoid new credit applications in the months before applying. A 740+ score typically qualifies for the best rates.
Shop at Least 3 Lenders
Banks, credit unions, and online lenders all price HELOCs differently. Credit unions often have lower margins. Online lenders may waive closing costs. Compare the full APR, not just the advertised rate.
Reduce Your LTV
If you can pay down your mortgage before applying, a lower LTV ratio improves your rate. Even a small reduction that crosses a threshold (e.g., 80% to 79%) can make a difference.
Ask About Relationship Discounts
Many banks offer 0.25% to 0.50% off if you set up autopay from their checking account. Some offer additional loyalty discounts for existing customers with deposits or investments.
Federal Reserve Rate Outlook
At its September 15-16 2026 meeting the Federal Reserve raised the federal funds rate by 0.25 percentage point to a target range of 3.75% to 4.00%, its first rate increase since 2023, citing elevated inflation. The vote was unanimous (12-0). The corresponding prime rate rose to 7.00%, effective September 17 2026. The committee's updated projections showed a majority of officials seeing the possibility of at least one further increase later in 2026.
For HELOC borrowers, the September hike feeds straight through: each 0.25% increase in the prime rate adds 0.25% to a variable HELOC rate, so existing lines will step up and new lines are being quoted higher. If the Fed raises again later in 2026, HELOC rates would rise further; if it later reverses course and cuts, HELOC rates would fall in step with the prime rate.
