How a HELOC Payment Is Calculated
A home equity line of credit allows you to borrow against available equity in your property. The amount you can potentially borrow depends on your home value, existing mortgage balance and the lender’s maximum combined loan-to-value requirement.
Many plans have a draw period followed by a repayment period. During the draw period, you may be able to borrow repeatedly up to your available credit limit. Once the repayment period begins, additional borrowing may no longer be available and the outstanding balance must be repaid.
What This Calculator Estimates
Home Equity
Estimated equity is the current property value minus the outstanding balance on your existing mortgage. Your lender may use an appraisal or another valuation method when determining eligibility.
Maximum Credit Line
The calculator estimates a potential maximum line using your selected combined loan-to-value percentage. Actual lender limits can be lower because of credit score, income, property type, existing debt and other underwriting requirements.
Draw-Period Payment
Some plans allow interest-only payments during the borrowing period, while others require some principal repayment. Your agreement determines the actual minimum payment formula.
Repayment Payment
The repayment estimate uses the balance being repaid, the selected rate and the repayment period. Payments can be substantially higher after the draw period ends, especially when principal must be amortized.
Rate Increase Scenario
Because many HELOCs have variable rates, a higher rate can increase the required monthly payment. The stress-test result lets you see how a selected rate increase could affect the estimated payment.
How Much Can You Borrow?
A simple starting point is to estimate your home’s value, subtract your existing mortgage balance and compare the result with the lender’s maximum combined loan-to-value requirement. The amount you qualify for can still be lower after the lender reviews your income, credit history, debts and property.
HELOC Payment Tips
Look beyond the introductory or current rate when comparing offers. Review the draw period, repayment period, minimum payment formula, annual fees, closing costs, rate caps and what happens when the borrowing period ends. A variable-rate plan can produce higher payments if interest rates rise.
Frequently Asked Questions
What is a HELOC?
A HELOC is a revolving line of credit secured by your home. You can generally borrow funds up to an approved limit during the draw period and repay the balance according to the plan’s terms.
How much equity do I have in my home?
A basic estimate is your current home value minus your outstanding mortgage balance. For example, a $500,000 property with a $300,000 mortgage balance has approximately $200,000 in equity.
Does a HELOC have a fixed payment?
Not necessarily. HELOCs commonly have variable rates, so the required payment can change as the applicable rate changes. The exact payment formula depends on the lender and agreement.
What happens when the draw period ends?
You generally enter the repayment period and may no longer be able to make additional draws. The outstanding balance may then be repaid through regular principal and interest payments or, under some plans, another repayment arrangement.
Why can the payment increase after the draw period?
During the draw period, some plans allow interest-only or relatively low minimum payments. During repayment, the outstanding principal may need to be amortized over a shorter period, producing a higher monthly payment.
Can a HELOC rate increase?
Yes. Many HELOCs have variable rates. The amount and timing of changes depend on the terms of the credit agreement, including the applicable index, margin and rate limitations.
Is a HELOC the same as a home equity loan?
No. A home equity loan generally provides a lump sum, while a HELOC is a revolving line that can allow repeated borrowing during the draw period.
Can I lose my home if I cannot repay a HELOC?
A HELOC is secured by the home. Failure to repay the debt can put the property at risk, so borrowers should carefully consider their ability to make payments.
