HELOC rates are typically variable, calculated as the Prime Rate + a margin. The margin depends on your credit score, CLTV, and other factors. As the Prime Rate changes, your HELOC rate changes — typically adjusting monthly or quarterly.
HELOC Rate = WSJ Prime Rate + Your Margin (0.5% - 5%)
Your margin is fixed at closing — only the Prime Rate fluctuates.
Your credit score is the single biggest factor in your HELOC margin. Borrowers with 740+ credit typically get margins of 0.5% - 1.5%, while scores below 660 may face margins of 3.5% - 5% or higher. Improving your score before applying can save thousands over the life of the line.
Combined Loan-to-Value (CLTV) = your first mortgage + HELOC divided by home value. Lower CLTV (more equity) means lower rates. Most lenders cap CLTV at 85-90%. At 70% CLTV you'll get better terms than at 85% CLTV.
Your debt-to-income ratio and income stability affect both approval odds and your rate. Lenders prefer DTI under 43%. Self-employed borrowers with strong tax returns can qualify for competitive rates.
Each lender sets its own margins and policies. Credit unions and community banks often offer lower rates than big national banks. Shopping multiple lenders is essential — differences of 0.5-1% on your margin are common.
The most common type — your rate is re-priced when the Prime Rate changes. Rates can go up or down over the life of the line.
Some lenders offer fixed-rate conversion options — you can lock all or part of your balance at a fixed rate for the remaining term.
| Credit Score Range | Typical Margin | Est. Rate (Prime=8.0%) |
|---|---|---|
| 740+ (Excellent) | 0.5% - 1.5% | 8.5% - 9.5% |
| 700-739 (Good) | 1.5% - 2.5% | 9.5% - 10.5% |
| 660-699 (Fair) | 2.5% - 3.5% | 10.5% - 11.5% |
| 620-659 (Poor) | 3.5% - 5% | 11.5% - 13.0% |
Pro tip: The Prime Rate is the Wall Street Journal Prime Rate, published daily. HELOC margins are set at closing and don't change — only the Prime portion moves. A borrower with a 1% margin at Prime of 8% pays 9%; if Prime drops to 7.5%, they pay 8.5%. Your margin is the negotiation point — shop lenders and compare margins, not just starting rates.
1
Pay down credit cards and fix credit report errors before applying. Even 20-30 points can lower your margin by 0.5% or more.
2
Compare margins across credit unions, banks, and online lenders. Rate shopping within 14-45 days counts as one credit inquiry.
3
Ask about promotional rates, no-closing-cost options, and margin discounts for auto-pay or existing customers.
