About HELOC Payment & Draw Periods
A Home Equity Line of Credit (HELOC) is a flexible borrowing tool that uses your home as collateral, typically offering lower interest rates than unsecured debt.
How a HELOC Works: Draw Period vs Repayment Period
A HELOC has two distinct phases. The draw period (typically 10 years) allows you to borrow money as needed, up to your credit limit, and you pay interest only on the amount you have drawn - though some lenders require amortizing payments. During this phase, you can borrow, repay, and borrow again like a credit card. The repayment period (typically 20 years) begins when the draw period ends. At this point, you can no longer draw new funds, and your outstanding balance must be repaid through fully amortizing monthly payments over the remaining term. The transition from interest-only payments to fully amortizing payments often creates significant payment shock that borrowers should plan for. Some HELOCs offer interest-only payments during the draw period, while others require amortizing payments from the start.
Interest Rates, Payment Shock & Total Cost
HELOCs typically have variable interest rates tied to the prime rate plus a margin (e.g., Prime + 1%). This means your monthly payment can change as interest rates rise or fall. Payment shock - the increase in monthly payment when transitioning from the draw period to the repayment period - is often the biggest financial challenge for HELOC borrowers. For example, on a $50,000 balance at 7.5% APR, the interest-only payment during the draw period might be $312/month, while the fully amortizing 20-year repayment payment jumps to $403/month - a 29% increase. Over the full life of the HELOC, total interest costs can range from 20-50% of the principal borrowed, depending on the interest rate, draw period type, and repayment speed.
Early Payoff & Accelerated Repayment Strategies
Paying off your HELOC faster can save thousands in interest. For example, on a $50,000 balance at 7.5% APR drawn over a 10-year interest-only draw period: if you use the standard 20-year repayment schedule, you would pay approximately $46,700 in interest. By accelerating to a 5-year payoff, you would pay approximately $10,100 in interest - saving $36,600. With a 3-year payoff, you would pay approximately $6,000 in interest - saving $40,700. The trade-off is higher monthly payments: approximately $1,002/month for 5 years or $1,556/month for 3 years, compared to the standard $403/month. Many HELOCs have no prepayment penalties, making accelerated payoff a powerful strategy.

Frequently Asked Questions
Everything you need to know about HELOC payments, draw periods, repayment periods, and payment shock.
A HELOC (Home Equity Line of Credit) works like a credit card - you have a credit limit and can borrow, repay, and borrow again during the draw period. You pay interest only on the amount you draw, not the full credit limit. A home equity loan provides a lump sum upfront with fixed monthly payments over a set term. HELOCs typically have variable interest rates, while home equity loans usually have fixed rates. HELOCs offer more flexibility but come with payment uncertainty as rates change.
When the draw period ends, your HELOC enters the repayment period. You can no longer draw new funds, and your outstanding balance must be repaid over the remaining term through fully amortizing monthly payments. This transition often causes payment shock because the repayment period payment is typically much higher than the interest-only payment during the draw period. For example, a $50,000 balance might jump from $312/month (interest-only) to $403/month (amortizing over 20 years).
Interest-only payments minimize your monthly cost during the draw period but mean your balance stays the same, leading to higher payments and more interest in the repayment period. Amortizing payments during the draw period gradually reduce your balance, lowering the principal that needs to be repaid later. Interest-only is better if you need maximum cash flow flexibility or expect to repay the balance in a lump sum. Amortizing is better if you want to minimize total interest costs over the full HELOC life.
Payment shock varies based on your balance, interest rate, and repayment term. For a $50,000 balance at 7.5% APR: an interest-only draw payment is $312/month. The fully amortizing 20-year repayment payment is $403/month - a 29% increase ($91/month). For a $100,000 balance at 8% APR: interest-only is $667/month, and the 20-year repayment payment is $836/month - a 25% increase ($169/month). The shorter your repayment term, the greater the payment shock.
Most HELOCs do not have prepayment penalties, allowing you to pay down the balance faster than scheduled without fees. However, some lenders may have prepayment penalties or early closure fees if you close the HELOC within the first few years. Always check your HELOC agreement for prepayment terms. Accelerating your payoff - even by making extra payments when possible - can save thousands in interest over the life of the loan.
Most HELOC interest rates are variable and calculated as the prime rate plus a margin set by the lender. For example, if the prime rate is 8.50% and your lender's margin is 1.00%, your APR would be 9.50%. The margin depends on your credit score, loan-to-value ratio, and the lender's pricing. Some lenders offer introductory fixed-rate periods (e.g., 1.99% for the first 6 months) before converting to the variable rate. Because rates are variable, your monthly payment can increase significantly if the Federal Reserve raises rates.
Financial advisors generally recommend keeping your HELOC utilization (drawn amount divided by credit limit) below 50%. Utilization above 80% signals higher risk to lenders and can negatively impact your credit score. High utilization also means you have less credit available for emergencies. Many lenders set maximum combined loan-to-value (CLTV) ratios of 80-90%, meaning your mortgage balance plus HELOC limit cannot exceed 80-90% of your home's value.
