Converting a HELOC to Fixed Rate: Lender-by-Lender Guide (April 2026)

Q: What is a Fixed-Rate Lock Option on a HELOC?

A Fixed-Rate Lock Option (FRLO) allows you to convert a portion of your drawn HELOC balance into a fixed-rate sub-loan at a specified rate and term, without refinancing the entire HELOC. The locked portion makes equal principal-and-interest payments at the fixed rate. The remaining HELOC balance continues as a variable-rate revolving line. US Bank, Wells Fargo, PNC, and TD Bank offer versions of this feature.

Q: Is the fixed-rate lock higher than my current HELOC rate?

Typically yes. The fixed-rate lock rate is usually 25-75 basis points above the current HELOC variable rate, in exchange for rate certainty. In a rising-rate environment where HELOC rates are expected to increase, locking at a small premium is often worth it. In April 2026, HELOC variable rates are approximately 9.75-11.00%; fixed locks are typically available at 10.25-11.50% depending on term.

Q: How many locks can I hold simultaneously?

It varies by lender. US Bank allows up to 3 concurrent fixed-rate locks. Wells Fargo allows up to 3. PNC Choice HELOC allows up to 5. TD Bank typically allows up to 3. Check your lender's current product terms, as these limits change.

Some lenders offer a Fixed-Rate Lock Option (FRLO) letting you convert part of your drawn HELOC balance to a fixed-rate sub-loan. No refinancing required. The variable HELOC continues alongside the locked portion. Here is which lenders offer this, what it costs, and when to use it.

How the Fixed-Rate Lock Option Works

Within your active HELOC draw period, you designate a portion of your drawn balance to be “locked” at a fixed rate for a defined term (typically 5, 10, or 15 years). The locked amount is removed from the revolving line and becomes a fixed-payment sub-loan with equal monthly P+I payments.

The remaining balance on the HELOC continues as variable rate. You can still draw against the variable portion (subject to the overall credit limit). You can sometimes create additional locks later.

The locked rate is typically 25-75bp above the current variable HELOC rate, reflecting the lender's cost of providing rate certainty. The fee per lock, if any, is $75-$200 at most lenders.

When to Use the Lock

Rising-rate environment

If you believe prime will rise further, locking converts variable exposure to fixed. The premium paid for certainty is small compared to a 100bp+ move.

Large draw you will not repay quickly

A significant balance with a multi-year payoff timeline has high variable-rate exposure. Locking gives payment certainty and removes the planning risk.

Desire for partial predictability

You want to keep some HELOC flexibility for future draws while making a large current draw more manageable. Split the balance.

Worked Math Example

Borrower has an $80,000 HELOC balance. Locks $30,000 at 8.25% fixed for 10 years. Remaining $50,000 stays variable at prime 7.25% + 2.75% = 10.00% APR.

Locked portion ($30k @ 8.25% / 10y)	$369/mo (P+I)
Variable portion ($50k @ 10.00%)	$417/mo (interest-only)
Total monthly payment	$786/mo
vs. fully variable ($80k @ 10.00%)	$667/mo (interest-only)
Difference (cost of lock certainty)	+$119/mo

If prime rises 100bp, the variable portion becomes $458/mo and the fully-variable total becomes $733/mo. The locked portion stays at $369/mo regardless.
