How to Use a HELOC to Pay Off Debt: Complete Step-by-Step Guide

Why HELOCs Are Effective for Debt Payoff

HELOCs offer several structural advantages that make them ideal for accelerating debt elimination:

Interest Rate Differential

The core principle is simple: replace high-interest debt with lower-interest debt. Most HELOCs carry interest rates between 7-10%, while credit cards typically charge 18-25% APR. This rate differential means more of your payment goes toward principal rather than interest.

Simple Interest vs. Compound Interest

HELOCs use simple interest calculated on the daily balance, while credit cards use compound interest. With simple interest, every dollar you deposit immediately reduces your interest charges. This mathematical advantage compounds over time.

Revolving Credit Structure

Unlike a home equity loan (which provides a lump sum), a HELOC allows you to:

• Draw funds as needed
• Repay and borrow again during the draw period
• Only pay interest on what you've borrowed
• Maintain flexibility for emergencies

The Five-Step HELOC Debt Payoff Process

Step 1: Calculate Your Available Equity

Most lenders allow you to borrow up to 80-85% of your home's value, minus your existing mortgage balance. This is called the Combined Loan-to-Value (CLTV) ratio.

Formula: (Home Value × 0.80) - Mortgage Balance = Available HELOC

Before applying, get an accurate estimate of your home's current market value through online tools, comparable sales, or a professional appraisal.

Step 2: Secure Your HELOC

When shopping for a HELOC, compare:

• Interest rate and margin: The margin is added to the prime rate
• Annual fees: Some HELOCs have yearly maintenance fees
• Draw period: Typically 10 years
• Repayment period: Usually 10-20 years after draw period ends
• Access methods: Checks, debit card, online transfers

Credit unions often offer the most competitive HELOC rates, sometimes 0.25-0.50% lower than traditional banks.

Step 3: Make Your First Chunk Payment

Once your HELOC is active, transfer funds to pay off your highest-interest debt first. This is called a "chunk" payment. The size of your chunk should be based on your monthly cash flow—the amount left over after all expenses.

General guideline: Your chunk size should be approximately 3-6 times your monthly cash flow, ensuring you can pay down the HELOC within a reasonable timeframe while maintaining a buffer for emergencies.

Step 4: Implement the Velocity Banking Cycle

This is where the strategy becomes powerful:

1. Deposit your income directly into the HELOC
2. Pay expenses from the HELOC throughout the month
3. Your positive cash flow (income minus expenses) automatically pays down the balance
4. Interest savings accumulate because your average daily balance stays lower

Step 5: Repeat the Cycle

Once your HELOC balance is paid down sufficiently, make another chunk payment toward your next debt. Continue this process until all debts are eliminated, including your mortgage if desired.

Debt Prioritization Strategy

When deciding which debts to target first, consider two approaches:

Highest Interest Rate First (Mathematically Optimal)

• Minimizes total interest paid
• Best for those motivated by numbers
• Typical order: Credit cards → Personal loans → Auto loans → Mortgage

Smallest Balance First (Psychologically Motivating)

• Creates quick wins that build momentum
• Best for those who need motivation
• May cost slightly more in interest overall

Important Considerations

Cash Flow Is Essential

This strategy only works if you have positive monthly cash flow—meaning your income exceeds your expenses. If your expenses equal or exceed your income, focus on creating a budget surplus before implementing this strategy.

Variable Rate Risk

HELOCs typically have variable interest rates tied to the prime rate. When interest rates rise, your HELOC rate will increase. Factor this into your planning and consider maintaining a buffer in your budget for potential rate increases.

Your Home Is Collateral

A HELOC is secured by your home. While you're actually reducing overall financial risk by eliminating debt faster, it's important to understand that failure to make payments could put your home at risk.

When This Strategy Works Best

• You have consistent positive cash flow each month
• Your high-interest debt rates significantly exceed HELOC rates
• You have sufficient home equity to secure a meaningful HELOC
• You're disciplined about not accumulating new debt
• You understand and accept the variable rate risk
