HELOC Rates After the Fed Hike: Your Payment Just Went Up — Fixed-Rate Alternatives
The Fed's September 16 hike took the prime rate to 7.50% — and every variable-rate HELOC repriced upward automatically. Average HELOC rates now run 8.90-9.40%, with 1-2 more hikes projected. Here's exactly how much more you're paying — and how to lock a fixed rate before the next one.
Quick Answer
Your HELOC rate rose exactly 0.25% within one billing cycle of the September 16 hike — that's how prime-indexed pricing works. On a $100K drawn balance, that's ~$250/year more in interest, and the dot plot signals another 25-50bps by December.
The escape hatch: fixed-rate conversion (most major lenders offer it) or a fixed home equity loan at 8.10-8.60%. Compare fixed HELOC conversion + equity loan quotes →
How Much More You're Paying Now
| HELOC Balance | Interest/Mo Before (prime 7.25%) | Interest/Mo Now (prime 7.50%) | If +50bps More (Dec) |
|---|---|---|---|
| $25,000 | $156 → $161 | $161 | $171 (+$10/mo) |
| $50,000 | $313 → $323 | $323 | $344 (+$21/mo) |
| $100,000 | $625 → $646 | $646 | $688 (+$42/mo) |
| $150,000 | $938 → $969 | $969 | $1,031 (+$62/mo) |
Assumes prime + 1.00% margin (typical for good credit). Interest-only payment shown; amortizing payments scale similarly.
3 Ways to Stop the Variable-Rate Bleed
Option 1: Fixed-Rate HELOC Conversion (Fastest — No New Loan)
Most lenders — Bank of America, Truist, PNC, Navy Federal, Figure — let you "lock" all or part of your balance at a fixed rate inside your existing HELOC. Typical conversion rate: 8.25-8.75%, often below your new variable rate. Call your servicer; usually a 10-minute process, sometimes free.
Best for: balances you'll repay over 3-10 years; keeps undrawn credit available.
Option 2: Fixed Home Equity Loan (Lowest Rate for Lump Sums)
Replace the HELOC balance with a fixed-rate home equity loan at 8.10-8.60% for 5-15 year terms. Payment never moves again — regardless of what Warsh's Fed does in October or December. See today's fixed equity loan rates →
Best for: a defined balance you want to amortize; you give up revolving access.
Option 3: Keep HELOC, But Reprice the Margin
Margins vary wildly — from prime + 0.50% at credit unions to prime + 2.00% at big banks. Refinancing your HELOC to a lender with a 0.50% lower margin saves $500/year per $100K. Some lenders still offer 6.50-7.49% intro rates for 6-12 months. Compare HELOC margins across 10+ lenders →
Best for: borrowers who need revolving access and can tolerate variable risk.
One Case Where You Should NOT Convert
If your first mortgage is below 5% — true for roughly half of all homeowners — do not touch it. A cash-out refinance at 7.2% to pay off a 9% HELOC would raise the rate on your entire balance. The equity plays (options 1-3) leave your cheap first lien untouched. That's the whole point of the second-lien market in a high-rate world.
If you're carrying the HELOC because of a renovation or debt consolidation, also compare a home equity investment (no monthly payment, share of appreciation) as a fourth path. See if you qualify for a no-monthly-payment equity unlock →

Did the Fed rate hike raise my HELOC payment?
Yes. The September 16, 2026 hike lifted the prime rate to 7.50%. HELOCs are priced as prime + margin (typically 0.50-2.00%), so a 0.25% Fed hike raises your HELOC rate by exactly 0.25% within one billing cycle. On a $50,000 HELOC balance that is roughly $10.40/month more in interest; on $100,000 it is ~$20.80/month — $250/year.
What is the average HELOC rate in September 2026?
The national average HELOC rate is approximately 8.90-9.40% after the September 16 Fed hike, depending on credit score, CLTV, and lender margin. Introductory teaser rates of 6.50-7.49% still exist for 6-12 months but convert to prime + margin afterward.
Can I convert my variable HELOC to a fixed rate?
Yes — most major HELOC lenders (Bank of America, Truist, PNC, Navy Federal) offer a fixed-rate conversion or "lock" feature that freezes a portion of your balance at today's fixed rate for a set term. Typical fixed conversion rates run 8.25-8.75% in September 2026 — often cheaper than your new variable rate, and immune to the 1-2 Fed hikes the dot plot still projects.
Is a home equity loan better than a HELOC after the Fed hike?
For a lump sum you plan to repay over 5-15 years, yes. Fixed home equity loans average 8.10-8.60% in late September 2026 — below most post-hike HELOC rates — and the payment never changes. HELOCs still win for staged expenses (renovations drawn over time) or as an emergency standby line, since you only pay interest on what you draw.
Will HELOC rates go down in 2027?
Not soon. The September dot plot projects 1-2 MORE hikes by end of 2026, which would push HELOC rates toward 9.5-10%. Any meaningful relief requires the Fed to reverse course — unlikely before mid-2027 unless inflation (core PCE 3.3%) collapses or the Iran conflict resolves and oil drops below $85.
Should I do a cash-out refinance instead of a HELOC right now?
Usually no — refinancing your whole mortgage at 7%+ to tap equity rarely makes sense if your first mortgage is below 5% (half of all mortgages are ≤4%). The exception: if your existing rate is already above 6.5%, a cash-out refi can consolidate first lien + equity at one fixed payment. Run both scenarios before deciding.
