How do HELOCs work over time?
A HELOC (home equity line of credit) is a revolving loan secured by your home that typically has two phases: a draw period and a repayment period. During the draw period, you can borrow as needed. During the repayment period, borrowing stops and repayment begins. Because HELOCs usually have variable interest rates, payments can change over time—sometimes significantly. Understanding how rates, draw periods, and repayment work together is critical to using a HELOC responsibly.
This guide explains each phase clearly so you know what to expect before borrowing.
How HELOC Interest Rates Work
Most HELOCs have variable rates based on: A benchmark index (often the Prime Rate or SOFR) and a lender-set margin.
Formula: Index + Margin = Your HELOC rate
Rates adjust when Market interest rates change or The benchmark index moves. This means monthly payments can increase or decrease over time.
The HELOC Draw Period
What is the draw period? The draw period is the time when you can access funds from your HELOC, usually lasting 5–10 years.
During this phase: You can borrow, repay, and borrow again. Payments are often interest-only. Monthly payments are usually lower.
Risks: Easy to over-borrow, Payments may rise if rates increase, Balance can grow quickly without discipline.
The HELOC Repayment Period
What happens when the draw period ends? Once the draw period ends: Borrowing stops, You begin repaying principal plus interest, Monthly payments often increase.
Repayment period details: Typically lasts 10–20 years, Payments are fully amortized, Interest rate usually remains variable.
This transition can cause payment shock if not planned for.
Payment Shock and How to Prepare
What is payment shock? Payment shock occurs when HELOC payments increase sharply due to: Rising interest rates or Transition from interest-only to principal repayment.
How to reduce payment shock: Make principal payments during the draw period, Borrow conservatively, Budget for higher future payments, Monitor rate trends.
