HELOC vs Home Equity Loan Calculator

Same amount, same term, two products. Put the variable HELOC rate next to the fixed home equity loan rate and see which one costs less, in the monthly payment and over the life of the debt.

The borrowing

Both are amortized over the same term here so the comparison is apples to apples. A real HELOC may run interest-only first.

Fixed lump sum or flexible line

Both products borrow against the equity in your home, but they behave differently. A home equity loan is a one-time lump sum at a fixed rate: you know the payment on day one and it never changes. A HELOC is a revolving line with a variable rate, so you draw what you need and the payment moves as the index moves.

To compare them fairly, this tool amortizes the same amount over the same term at each rate, then shows the monthly payment and the total interest for both. The fixed loan gives you certainty. The HELOC often starts cheaper but carries the risk that the rate climbs, since most HELOC rates float with the prime rate published by the Federal Reserve.

How to read the result: if the HELOC rate sits below the loan rate, it wins today. Bump the HELOC rate up a point or two to see how quickly that advantage disappears if rates rise during your repayment.

Neither answer is universal. A borrower who will clear the balance in two years may happily take the variable line, while someone budgeting for fifteen years of payments may sleep better with the fixed loan. Match the product to your timeline, not just to the headline rate, and confirm fees and rate caps with the lender.

FAQs

What is the main difference between a HELOC and a home equity loan?

A home equity loan hands you a lump sum at a fixed rate with a set monthly payment. A HELOC is a revolving line with a variable rate, so you draw as needed and the payment can change. The CFPB describes the two as the main ways to tap home equity.

Which one has a lower payment?

It depends on the rates. A HELOC often starts lower but can rise if the prime rate climbs. A home equity loan locks the rate, so the payment never moves. This tool lets you compare both at rates you choose.

Should I pick fixed or variable?

Fixed suits borrowers who want a predictable payment and plan to keep the balance for years. Variable can win if you expect to repay quickly or believe rates will fall. There is no single right answer.

Are these numbers final?

No. They are estimates, not a loan offer. Real terms, fees and rate caps vary by lender and by your credit profile.
