A home equity line of credit (HELOC) lets you borrow against your home's equity. HELOCs work like credit cards, offering a revolving credit line based on your home's value minus your outstanding mortgage balance.
Your home is likely one of your biggest investments. A HELOC lets you tap this equity for home improvements, debt consolidation or college expenses.
MoneyGeek's calculator estimates how much you can borrow, your potential monthly payments and your loan-to-value (LTV) ratio.
Understanding HELOC payments requires knowing about variable interest rates, loan stages and rate caps. Before getting a HELOC, learn how these factors affect both the draw and repayment periods.
Lenders consider several factors when determining HELOC rates and terms. You control some factors, while market conditions influence others.
Your credit score affects your terms and rates, just like other loans. Higher scores lead to better terms and lower rates.
Your home's current market value determines how much you can borrow. Higher value means more accessible equity.
Lenders review your debt-to-income ratio — your total debt compared to your income. High existing debt might limit borrowing or affect your interest rate.
Economic conditions and federal interest rates influence HELOC rates.
Lenders have different policies and thresholds. Comparing terms from multiple lenders helps you find a better fit.
This shows the difference between your home's value and your current mortgage. Lenders use this ratio to assess risk and determine your maximum borrowing amount.
Getting a HELOC depends on your individual circumstances. We analyzed scenarios where it's the best financing option.
Emma, a freelance graphic designer, works from her home studio. She wants to transform it into a modern space with large windows for natural light and dedicated project areas. She also plans to upgrade her kitchen into a gathering spot for family and clients.
Emma's renovation needs don't come all at once, so she prefers financing that adapts to her project's phased timeline. Her income is substantial but varies monthly, making borrowing and repayment flexibility necessary.
A HELOC's flexible credit line lets Emma access funds as each project stage begins. Interest-only payment options initially help Emma manage her budget without immediate principal repayment.
Lucas accumulated high-interest credit card debt and an auto loan while pursuing his photography gallery dream. This venture didn't immediately turn profitable. Lucas needs a solution that consolidates debt and offers a lower interest rate than his credit cards.
A home equity loan fits Lucas better. It provides the lump sum needed to clear existing debts plus a fixed interest rate more favorable than his current rates. This simplifies managing multiple payments and fluctuating interest.
HELOCs are one of several financial products that allow homeowners to tap into their home’s equity. Other options include home equity loans and cash-out refinances. These options have several things in common:
However, there are also distinct differences between them. Let’s explore these further.
A home equity loan provides homeowners a one-time lump sum by leveraging the equity in their property, usually at a fixed interest rate. Let's explore what sets them apart from HELOCs.
Type of Credit | HELOCs offer a flexible revolving line for borrowing as needed, while home equity loans provide a one-time lump sum. |
Interest Rate | HELOCs often have variable rates that can fluctuate, while home equity loans have fixed rates, locking in your costs. |
Payment Structure | HELOCs have draw and repayment phases, potentially allowing interest-only payments during the draw period. Home equity loans require regular monthly principal and interest payments from the start. |
Another loan product that leverages your home’s equity is a cash-out refinance. These allow homeowners to replace their current mortgage with a new one for a larger amount than they owe, pocketing the difference in cash. Here’s how they differ from HELOCs.
Type of Borrowing | HELOCs provide a revolving credit line for flexible borrowing. A cash-out refinance replaces your mortgage with a new, larger one and gives you the difference in cash. |
Impact on Mortgage | Cash-out refinance alters your original mortgage terms and rates, possibly extending your repayment period. HELOCs act as a second mortgage without affecting your first mortgage. |
Interest Rates | HELOCs usually have variable interest rates, while cash-out refinances offer fixed rates. |
If you enter your figures into a HELOC calculator and don't like the results that come back, it may mean you need to sit tight for another couple of years before tapping your home equity. Not only are there other loan options for you to consider in the meantime, but making regular payments on your mortgage and natural home price appreciation will increase the amount of equity you have over time. — Timothy Manni, Mortgage and Real Estate Consultant
A HELOC calculator can make your borrowing experience smoother. We’ve compiled a list of frequently asked questions to help you get the most out of this tool and decide if a HELOC is suitable for your financial needs.
The calculator uses your home's value, outstanding mortgage balance, credit score and other financial details to estimate your maximum credit line.
Your credit score range helps estimate the interest rate you may qualify for, which affects the total credit line and your potential monthly payments.
Inputting your payoff goal helps estimate your monthly payments during the repayment period. It can help you develop repayment strategies.
Since HELOCs often have variable rates, you can use the calculator to see how changes in the APR might affect your monthly payments, helping you plan for different interest rate environments.
While our calculator provides an estimate based on minimum payments, it’s best to consult directly with your lender or a financial advisor to understand the impact of additional payments on your HELOC.
