The loan amount you can borrow as a HELOC depends on your home equity. To calculate your home equity line of credit monthly payment, first calculate your home equity to know how much you can borrow as a home equity line of credit.
Your home equity is the difference between your home’s current value and your current mortgage balance. You can borrow up to 65% of your home equity as a HELOC.
During the draw period, you have to pay only interest on the withdrawal amount, then during the repayment period, you have to pay principal plus interest.

What Is a Home Equity Line of Credit (HELOC)?
A Home Equity Line of Credit, or HELOC, is a revolving line of credit secured by the equity you have built up in your home. Unlike a traditional loan where you receive a fixed lump sum upfront, a HELOC works more like a credit card: you are approved for a maximum credit limit and can borrow as much or as little as you need, repay it, and borrow again — all during an initial period called the draw period.
Because a HELOC is backed by your property, interest rates are typically much lower than unsecured credit cards or personal loans. This makes it one of the most cost-effective ways to access funds for large expenses such as home renovations, education, debt consolidation, or emergency costs.
Key HELOC Facts at a Glance
- Borrow up to 65–85% of your home equity (varies by lender)
- Two phases: draw period (interest only) + repayment period (principal + interest)
- Variable interest rate, typically tied to the prime rate
- Current average HELOC rate: approximately 7.47% APR (June 2026)
- Interest accrues only on the amount you actually draw, not the full credit limit
How to Use This HELOC Calculator
Our HELOC payment calculator is designed to be straightforward. Here is what each input field means and how it affects your results:40.
Loan Amount
Enter the amount you plan to borrow from your line of credit. Most lenders in Canada allow you to access up to 65% of your home’s appraised value, minus any outstanding mortgage balance.
In the United States, this ceiling is typically 80–85% of home value (combined loan-to-value). Enter a realistic withdrawal figure, not your maximum credit limit, for the most accurate payment estimate.
Interest Rate (%)
Enter the annual interest rate quoted by your lender. HELOC rates are usually variable and move with the prime rate set by the central bank.
As of June 2026, the national average HELOC rate sits near 7.47% APR. You can test different rate scenarios in the calculator to see how a 1–2% increase would change your monthly obligation.
Draw Period Years
The draw period is the phase during which you can access funds freely. Our calculator defaults to 5 years, though draw periods typically range from 5 to 10 years depending on the lender. During this time, many HELOCs require interest-only payments on the balance you have drawn.
Repayment Period Years
Once the draw period closes, the HELOC enters the repayment period. You can no longer withdraw funds and must repay both principal and interest in equal monthly instalments (EMI). Our calculator defaults to 10 years. Repayment periods commonly run 10 to 20 years.
Understanding Your HELOC Results
After clicking “Calculate Your Monthly Payment,” the calculator displays four key figures:
Draw Period Monthly Payment (Interest Only)
This is the minimum monthly payment during the draw phase. It is calculated as: Loan Amount × (Annual Rate ÷ 12). Because no principal is repaid, this amount stays relatively low and predictable as long as the interest rate does not change.
Repayment Period Monthly Payment (Principal + Interest)
This is your EMI once the repayment phase begins. It is calculated using the standard amortization formula, accounting for your full loan balance, interest rate, and number of repayment months. Expect this figure to be noticeably higher than your draw period payment — sometimes more than double.
Total Interest
This figure adds the total interest paid during the draw period (all monthly interest payments combined) and the interest portion of your repayment period EMIs. It gives you the true cost of borrowing over the full life of the HELOC.
Total Loan Payment
This is the grand total you will pay to the lender: the sum of every draw period payment and every repayment period EMI. Subtracting the original loan amount from this figure gives you your total interest cost.
Draw Period vs. Repayment Period: What to Expect
The two-phase structure of a HELOC is what makes it both flexible and potentially surprising if you are unprepared. Here is a side-by-side comparison:
| Draw Period | Repayment Period |
| Borrow freely up to your credit limit | No new withdrawals allowed |
| Interest-only minimum payments | Full principal + interest (EMI) payments |
| Payments are lower and more flexible | Payments are higher and fixed |
| Typically, 5–10 years | Typically, 10–20 years |
| Great for staged or ongoing expenses | Focus is on debt elimination |
| Balance may not decrease at all | Balance decreases with every payment |
Payment shock is a real risk. When the draw period ends, homeowners who have been paying interest only can see their monthly obligation double or triple overnight. Financial planners commonly recommend making voluntary principal payments during the draw period to flatten this curve.
HELOC Payment Calculation Formulas
The calculator uses two standard financial formulas:
Draw Period Monthly Payment Formula
Monthly Payment = Loan Amount × (Annual Interest Rate ÷ 12)
Example: $50,000 loan at 7.5% annual rate = $50,000 × (0.075 ÷ 12) = $312.50 per month (interest only).
Repayment Period EMI Formula
EMI = P × r × (1 + r)ⁿ ÷ [(1 + r)ⁿ − 1]
Where P = loan principal, r = monthly interest rate (annual rate ÷ 12), n = total number of repayment months.
Example: $50,000 at 7.5% over 10 years (120 months) = EMI of approximately $593.51 per month.
HELOC vs. Home Equity Loan vs. Cash-Out Refinance
A HELOC is one of three common ways to access your home equity. Here is how they compare:
| Feature | HELOC | Home Equity Loan | Cash-Out Refinance |
| Disbursement | Revolving credit line | Lump sum upfront | Lump sum at closing |
| Interest Rate | Variable (usually) | Fixed | Fixed or variable |
| Payment Type | Interest only (draw) then EMI | Fixed EMI from day one | Fixed EMI replaces existing mortgage |
| Flexibility | High — borrow as needed | Low — fixed amount | Low — full refinance |
| Best For | Ongoing or staged expenses | One-time, known costs | Lowering existing mortgage rate |
| Risk | Rising variable rates | None if fixed rate | Resets mortgage clock |
Who Qualifies for a HELOC?
Lender requirements vary, but most institutions look at the following factors when evaluating a HELOC application:
Home Equity
You generally need at least 15–35% equity in your home (meaning your mortgage balance must be well below the home’s value). Lenders calculate this using the Combined Loan-to-Value (CLTV) ratio.
Credit Score
A credit score of 680 or higher is typically required for approval, though the best rates are usually reserved for borrowers with scores above 740.
Debt-to-Income (DTI) Ratio
Most lenders prefer a DTI ratio of 43% or lower. A lower DTI signals that you have sufficient income to manage additional monthly payments.
Stable Income and Employment History
Lenders will verify your income and employment to ensure you can sustain both your existing mortgage and the new HELOC payments throughout the repayment period.
Tips to Manage Your HELOC Wisely
- Use the calculator to test multiple interest rate scenarios before committing. A 2% rate increase can significantly raise your monthly payment.
- Make principal payments during the draw period whenever possible. Even small extra payments reduce the balance subject to interest and lower your eventual repayment EMI.
- Know your rate caps. Most variable-rate HELOCs have a lifetime cap (often 18%). Understanding your worst-case scenario protects your long-term budget.
- Set a personal borrowing limit. Just because you are approved for $100,000 does not mean you should use it all. Borrow only what you need to minimize total interest.
- Plan for the repayment phase before the draw period ends. Adjust your monthly budget 6–12 months in advance to accommodate the higher EMI.
- Compare multiple lenders. HELOC rates and fees vary widely. A difference of even 0.5% on a $75,000 balance over 10 years represents thousands of dollars in interest.
Frequently Asked Questions (FAQ):
Is HELOC interest tax-deductible?
In Canada, HELOC interest is generally tax-deductible only if the borrowed funds are used to earn investment income. In the United States, interest on a HELOC may be deductible if the funds are used to “buy, build, or substantially improve” the home that secures the loan. Consult a qualified tax advisor for guidance specific to your situation.
Can I pay off my HELOC early?
Yes. Most HELOCs allow early repayment without a penalty, though some lenders may charge a prepayment fee within a specific window. Check your loan agreement for details.
What happens at the end of the draw period?
The revolving credit line closes and converts to a repayment-only loan. You will be required to repay both principal and interest in equal monthly instalments over the agreed repayment term. Some lenders allow a balloon payment option at this stage.
Does a HELOC affect my credit score?
Yes. Applying for a HELOC triggers a hard credit inquiry, which may temporarily lower your score by a few points. Additionally, the credit line will appear on your credit report as a revolving account. Keeping utilization low and making payments on time will positively affect your score over time.
What is the difference between a HELOC and a home equity loan?
A home equity loan provides a single lump sum at a fixed interest rate with equal monthly payments from day one. A HELOC provides a flexible credit line with variable rates and interest-only payments during the draw phase. Use this calculator alongside our Home Equity Loan Calculator to compare which option better suits your needs.
How much can I borrow with a HELOC?
Borrowing limits depend on your home’s appraised value, outstanding mortgage balance, and the lender’s maximum loan-to-value (LTV) ratio. In Canada, the maximum is typically 65% of the home’s value under federal guidelines. In the United States, lenders commonly allow combined LTV of up to 85%. Use the Loan Amount field in our calculator to model different borrowing levels.
