An interest-only HELOC is a unique and powerful home equity line of credit that allows homeowners to borrow against the equity in their homes, paying only the interest during an initial draw period. This type of secured home equity credit line is appealing for its flexibility, but it comes with potential risks and complexities that borrowers need to understand before making a commitment.

What is an Interest-Only HELOC?

An interest-only HELOC can be a flexible and cost-effective way to access home equity, especially for short-term needs or incremental home improvements.

This type of home equity loan does requires a clear understanding of the future financial commitments, including the potential for increased payments and variable interest rates.

This article will delve into what an interest-only home equity line of credit is, its benefits, potential drawbacks, and why it might or might not be the right fit for you.

Understanding the Basics of an Interest Only Home Equity Line of Credit

As you may already know, the HELOC operates like credit card in that it provides a revolving line of credit. However, unlike a traditional credit card, a HELOC is secured by your home. The funds you borrow are based on the home’s equity. Most traditional mortgage lenders will offer a home equity line of credit between 80 and 85% of the appraised value, minus any remaining mortgage balance. There are a few HELOC lenders that will offer interest only home equity credit lines up to 90% with good credit scores. This HELOC loan is divided into two main phases: the draw period and the repayment period.

In a traditional HELOC, borrowers pay both interest and principal each month. But an interest only HELOC loan is different: during the draw period, you are only required to pay the interest on the amount borrowed. While this lowers your monthly payments initially, you will eventually face full principal and interest payments in the repayment period.

How Does an Interest-Only HELOC Loan Work?

Imagine you’re at a buffet with endless choices—you can pick and choose what you want, but eventually, you’ll have to settle the bill. An interest-only HELOC works similarly to an interest only mortgage loan, but there are a few slight differences with an equity line of credit. The line of credit has a specified draw period. During the initial interest only period, typically 5 to 10 years, you can use the funds available to you without making a substantial financial commitment beyond interest payments. This means your initial monthly payment is much lower than they would be if you were also paying off the principal.

But, just like that buffet tab, the draw period eventually ends, and you must start paying back the amount you’ve borrowed along with the interest. At this point, your monthly payment may increase significantly, depending on the amount you’ve borrowed and the length of the repayment term.

Let’s say your HELOC has a 10-year draw period with a 10-year repayment period. During the first 10 years, you only pay the interest on what you’ve borrowed. But once the draw period is over, you enter the repayment phase, where you must pay both the principal and interest each month. This shift can lead to a “payment shock,” as monthly costs can increase substantially. It’s essential to plan ahead and ensure that you’ll be able to manage these higher payments when the time comes. Many borrowers will choose to refinance a HELOC when the draw period ends and some will request a fixed rate HELOC when the repayment period begins.

Benefits of an Interest-Only HELOC

An interest-only HELOC offers several benefits that may appeal to different types of borrowers:

  1. Lower Initial Payments: During the draw period, borrowers benefit from a lower monthly payment, as they only need to make a minimum payment to cover the interest. This can free up cash flow for other expenses, investments, or emergencies.
  2. Flexible Access to Funds: Like a traditional HELOC, an interest-only HELOC allows borrowers to withdraw money as needed during the draw period, which can be ideal for ongoing home improvement projects or other financial needs that arise over time.
  3. Potential Tax Benefits: When used for home improvements, the interest on a HELOC may be tax-deductible. This depends on individual tax situations and should be confirmed with a tax professional.
  4. Possibility of Refinancing: If the housing market improves or if your income increases, you might consider refinancing the HELOC before the repayment period begins, potentially reducing your monthly payments. Also consider increasing your HELOC limit.

In essence, an interest-only HELOC can be a strategic tool for those who need immediate access to cash but want to keep their initial payments low. However, as with any financial product, it’s crucial to fully understand both the short-term benefits and the long-term obligations.

Potential Drawbacks of an Interest-Only HELOC

While an interest-only HELOC may sound appealing, it also comes with certain risks and drawbacks:

  1. Payment Shock: As mentioned earlier, borrowers can experience a significant increase in monthly payments once the draw period ends. Transitioning from paying only the interest to covering both interest and principal can be financially straining if not properly anticipated.
  2. Risk of Over-Borrowing: The flexibility of a HELOC can sometimes lead borrowers to withdraw more than they can comfortably repay, especially if they’re only required to make minimal interest payments initially. This can lead to a cycle of debt that is difficult to escape.
  3. Variable Interest Rates: Most HELOCs, including interest-only ones, have variable interest rates. While rates may start low, they can increase significantly over time, leading to higher payments than originally anticipated. Think of it as a roller coaster—exciting at first, but you never know just how steep the next drop might be. If you are uncomfortable with adjustable rates, consider home equity loans that offers a fixed interest rate and fixed monthly payments.
  4. Possibility of Losing Your Home: Since a HELOC is secured by your home, failure to make payments could ultimately lead to foreclosure. This is a serious risk, especially if you struggle to meet the higher payments during the repayment period.
  5. Negative Amortization: If you don’t pay down any principal during the draw period, the loan balance remains the same, meaning you’ll have to repay the full borrowed amount during the repayment phase. This can create a heavier financial burden in the long run. Most lenders do not offer a negative amortization option with a home equity line of credit but be prudent and verify that before signing paperwork.

Is an Interest-Only HELOC Right for You?

So, who should consider an interest-only HELOC? Imagine you’re an artist with a blank canvas, given the freedom to paint at will. An interest-only home equity line of credit offers a similar financial canvas, providing flexibility to those who need it most—such as homeowners planning multiple renovation projects over time, or those who anticipate a future increase in income. This financial product may be a suitable choice if:

  • You have a clear plan to repay the HELOC loan before or during the repayment period.
  • You’re using the funds for home improvements that may increase your property’s value.
  • You have confidence in a stable or increasing future income to cover potential payment increases.

However, if you’re someone who prefers financial predictability, a traditional HELOC or another loan product might better suit your needs. Before deciding, it’s essential to ask yourself: Can I manage higher payments when the draw period ends? If the answer is uncertain, a HELOC with an interest only payment might not be the ideal solution.

How Do You Calculate an Interest Only Payment on a HELOC?

To calculate an interest-only payment on a HELOC, start by identifying your HELOC interest rate and the amount borrowed (the outstanding balance). Since home equity lines often have variable interest rates, check with your lender to confirm the current rate applicable to your loan. Once you have the mortgage rate, convert it to a monthly rate by dividing the annual rate by 12. For instance, if your HELOC’s annual interest rate is 6%, the monthly rate is 0.5% (6% divided by 12). Next, multiply the outstanding balance by the monthly mortgage rate.

For example, with a balance of $50,000 and a 0.5% monthly rate, your interest-only payment would be $250 (0.5% of $50,000). This payment covers only the interest, without reducing the principal amount. Remember, if your HELOC has a variable rate, this payment can change each month as the rate fluctuates. Accurately calculating your interest-only payments allows you to budget effectively and understand how much you’ll need to pay if rates increase. Consult with your lender or use an online calculator for assistance if needed, especially if you plan to make additional payments toward the principal.

Here are three examples how to calculate interest only payments on a HELOCt​: These examples assume different loan amounts and HELOC interest rates. (Please note these are examples not to be confused with a today’s HELOC rates)

Example 1

  • Loan Balance: $25,000
  • Annual Interest Rate: 5%
  • Monthly Interest Rate: 5% ÷ 12 = 0.4167%

To calculate the monthly interest-only payment:

  • Interest Payment = $25,000 × 0.4167% = $104.17

So, the HELOC interest-only payment for this month would be $104.17.

Example 2

  • Loan Balance: $50,000
  • Annual Interest Rate: 6%
  • Monthly Interest Rate: 6% ÷ 12 = 0.5%

To calculate the monthly interest-only payment:

  • Interest Payment = $50,000 × 0.5% = $250

Here, the HELOC interest-only payment for this month is $250.

Example 3

  • Loan Balance: $100,000
  • Annual Interest Rate: 7%
  • Monthly Interest Rate: 7% ÷ 12 = 0.5833%

To calculate the monthly interest-only payment:

  • Interest Payment = $100,000 × 0.5833% = $583.33

The HELOC interest-only payment for this month would be $583.33.

Each example demonstrates how to calculate the home equity line of credit interest-only payment by multiplying the loan balance by the monthly mortgage rate. We hope this helps you know how to calculate HELOC interest only payment​s in the future. This keeps payments low initially, covering only the interest without reducing the principal. It is important to shop the best HELOC lenders and get actual interest rates and payment quotes that you qualify for. based on your credit score, debt to income ratio (DTI) and loan to value (LTV). Check with trusted lenders for the current HELOC credit requirements.

How is interest calculated on a HELOC?

Interest on a HELOC is typically calculated based on the daily balance and the loan’s variable interest rate. Most HELOCs use a variable rate tied to the prime rate plus a margin, which can fluctuate based on market conditions. Each day, the outstanding balance of the HELOC is multiplied by the daily interest rate—found by dividing the annual interest rate by 365—to calculate that day’s interest charge.

For instance, if your HELOC has a 6% annual rate, the daily rate is approximately 0.0164% (6% divided by 365). If your balance is $10,000, the interest for that day would be $1.64 ($10,000 x 0.0164%). These daily interest charges accumulate over the billing period, and you pay them each month along with any principal payments if applicable. Since the rate and balance may vary, the interest owed each month can change, making it important to monitor both regularly.

Considerations Before Applying for an Interest-Only HELOC

1. Understand Your Budget and Financial Outlook

Before committing, review your monthly budget and consider potential changes in your financial situation. Could you handle a significant jump in monthly payments if rates were to rise? Are there any expected changes in your income, such as a new job, retirement, or other financial responsibilities?

2. Have a Repayment Plan in Place

The HELOC with interest only payments can lead to financial strain if you’re not prepared for the repayment phase. Having a plan to pay down some of the principal during the draw period can ease the transition and reduce the likelihood of payment shock.

3. Consider the Interest Rate Environment

Since most home equity lines have variable interest rates, it’s wise to consider the current interest rate environment and how potential fluctuations might impact your loan. Speaking with a financial advisor can help you assess your risk tolerance and understand how changes in the market could affect your payments. Again consider a home equity loan if you think the trend of interest rates is going upward.

9 Key Points on the Interest-Only HELOC

An interest-only Home Equity Line of Credit (HELOC) allows homeowners to borrow against their home’s equity, paying only the interest during an initial period. While this setup offers flexibility and lower monthly payments at first, it also carries risks that potential borrowers should consider. Here are nine essential points to understand about interest-only HELOCs.  By considering these nine key points, homeowners can better assess whether HELOC interest only payment align with their financial goals and risk tolerance.

1. What Is an Interest-Only Home Equity Line of Credit?

An interest-only HELOC lets homeowners borrow money based on the equity they’ve built in their property. Unlike traditional home equity lines, which require both interest and principal payments from the start, an interest-only home equity line of credit allows borrowers to pay only interest during the initial “draw period.” This setup makes for lower monthly payments initially, freeing up cash flow for other needs.

2. How the Draw Period Works

The draw period typically lasts between 5 and 10 years, during which borrowers can withdraw funds as needed and only pay the interest on the borrowed amount. This feature can be beneficial for those who have fluctuating income or need funds over time for ongoing projects, such as home renovations.

3. Lower Monthly Payments in the Beginning

One of the primary attractions of an interest-only HELOC is the lower monthly payment during the draw period. Since borrowers aren’t required to pay down the principal at this time, payments are often significantly lower than those of a fully amortizing loan. This can make it easier to manage finances, especially if there are other high expenses to handle.

4. Repayment Period Increases Monthly Payments

Once the draw period ends, borrowers enter the repayment period, typically lasting 10 to 20 years. During this phase, they must repay both the principal and interest, leading to significantly higher monthly payments. This transition is known as “payment shock,” and without proper planning, it can strain finances. Understanding this shift is essential for managing the loan effectively.

5. Variable HELOC Interest Rates

Most HELOCs, including interest-only options, come with variable interest rates. This means that monthly payments can fluctuate based on changes in the prime rate or market interest rates. While interest rates may start low, they can increase over time, potentially making the loan more expensive. Borrowers should assess their comfort with this unpredictability before committing.

6. The Risk of Over-Borrowing

When you pay interest only payments on a HELOC, borrowers can withdraw funds up to their maximum approved limit. However, the flexibility to access large amounts of credit, combined with low initial payments, may lead some to over-borrow. Taking on more debt than necessary can create financial strain in the long run, especially when the repayment phase begins.

7. Potential Tax Benefits with HELOC Interest 

For homeowners using their HELOC funds for substantial home improvements, the interest paid on the loan may be tax-deductible. This potential benefit can make interest-only HELOC loans more appealing for those looking to increase their property value through renovations. Borrowers should check with a tax professional to confirm eligibility for these deductions.

8. Possibility of Refinancing

As the draw period nears its end, some borrowers may explore refinancing options to manage upcoming payments. If market conditions are favorable, refinancing can help reduce monthly payments or switch from a variable rate to a fixed one. However, refinancing may come with fees, and borrowers should weigh the pros and cons carefully. There is the option for a refinance with a an unsecured personal loan if the amount owed on the HELOC is minimal. You should also consider a cash out refinance or refinancing with a home equity loan that offers a lump sum that can pay off the adjustable rate home equity debt. With a conventional refinance or home equity loan you would be paying principal and interest payments rather than if you pay interest only payments with a HELOC.

9. Risk of Losing Your Home

Like other HELOCs, an interest-only HELOC is a secured loan, meaning your home is collateral. Failure to make payments, especially during the repayment period when they are higher, could result in foreclosure. Borrowers need to understand this risk and ensure they have a solid repayment plan to avoid jeopardizing their home.

What are the closing costs on an interest only home equity line of credit?

HELOCs usually incur similar closing costs to a home equity loan, generally amounting to around 2% to 5% of the loan amount or credit line. However, unlike a home equity loan, an equity line of credit allows you to use and reuse your credit line within a designated period known as the HELOC draw period. However, if you take out a HELOC with $100,000 credit limit, you are still paying closing costs based on the total credit line amount.

Takeaway on the Interest Only HELOC

An interest-only HELOC offers an appealing mix of flexibility and lower initial payments, making it a popular option for borrowers who need immediate access to funds without committing to full monthly payments. However, it also carries risks, particularly for those unprepared for the higher payments that come with the repayment phase. Like any loan product, an interest-only home equity line of credit should be considered carefully, with a clear understanding of your financial needs and long-term goals.

Ultimately, the decision to pay interest only payments on a HELOC should not be made lightly. Is it the best option for your current financial situation and future plans? For some, it may be a powerful tool; for others, a potential pitfall. By weighing both the benefits and drawbacks, and by consulting with financial professionals as needed, you can make an informed decision about whether interest-only HELOC loans are the right choice for your financial journey.

FAQ on Interest Only HELOCs

What is the interest-only period?

The interest-only HELOC loan is a phase during which borrowers are only required to pay the interest on the amount they’ve borrowed, without paying down the principal balance. This period typically lasts for the length of the HELOC draw period, often between 5 to 10 years. During this time, monthly payments are lower since they don’t include principal repayments.

What is the HELOC draw period?

The HELOC draw period is the initial phase of a Home Equity Line of Credit during which the borrower can access funds from their credit line as needed, up to the approved limit. This phase typically lasts between 5 and 10 years, depending on the terms of the HELOC. During the draw period, borrowers often have the option to HELOC payments with a minimum payment to cover the interest on the portion they accessed.. After the draw period ends, borrowers can no longer access additional funds and transition into the repayment phase, where both interest and principal are due.

What is the HELOC repayment period?

The HELOC repayment period follows the draw period and is the phase during which borrowers must repay the outstanding balance in full, including both principal and interest. This phase usually spans 10 to 20 years, depending on the loan terms. During this time, monthly payments increase as they cover both principal and interest, contrasting with the lower, interest-only payments during the draw period. Many borrowers request options for home equity loans at this time, because the monthly payment is fixed. Planning for this phase is essential, as the shift to higher payments can strain finances if not anticipated.

Does the Wall Street Journal Publish HELOC Rates?

The Wall Street Journal publishes benchmark interest rates, including the widely used prime rate, which many lenders base their Home Equity Line of Credit rates on. Updated periodically to reflect Federal Reserve adjustments, the Wall Street Journal prime rate serves as a standard across the lending industry. Most HELOCs have variable interest rates tied to this prime rate, with lenders adding a margin based on a borrower’s creditworthiness. The Wall Street Journal regularly updates these rates, allowing consumers and lenders to stay informed on current market conditions, which can directly impact monthly HELOC payments and overall loan costs.
