HELOC vs Cash-Out Refinance Calculator

A cash-out refinance almost always shows a higher monthly payment than a HELOC, and people read that as the refinance being more expensive. Sometimes it is, sometimes it is not, and the payment does not tell you which.

The refinance payment includes principal repayment on the entire mortgage. A HELOC in its draw period is typically interest-only, so the payment is pure cost and reduces nothing. Ten years of HELOC payments leaves you owing exactly what you borrowed.

That is why the comparison here includes the balance still owed. A route that produces a low payment while leaving more debt outstanding has not saved you anything; it has deferred the cost.

The other reason payments mislead is the reset. Refinancing a mortgage you are eight years into restarts a 30-year amortisation, which lowers the payment by stretching the term and raises the total interest substantially. The payment looks better and the position is worse.

If keeping the payment comparable matters, ask for a refinance over the remaining term rather than a fresh thirty years. Many lenders will quote it and few offer it unprompted.

The home equity loan deserves more attention than it gets. For someone who needs a known lump sum, has a low first-mortgage rate to protect, and does not want variable-rate exposure, it is frequently the best of the three — and it is the one lenders promote least.

HELOC draw period —

usually ten years, during which you can borrow and repay freely and payments are often interest-only. You pay interest only on what you have actually drawn.

HELOC repayment period —

typically twenty years after the draw ends, when the balance amortises. The payment jumps sharply at this transition, and it catches people out.

Variable rate —

HELOCs are generally prime plus a margin and reprice as rates move. A HELOC that looks affordable today can cost meaningfully more in two years.

Cash-out refinance —

one new fixed-rate loan replacing the old. Predictable, and it resets the amortisation clock.

Home equity loan —

the third option — a fixed-rate second mortgage, lump sum, fixed payment. It keeps the first mortgage intact like a HELOC but removes the variable-rate risk.

Closing costs —

2% to 5% of the loan on a refinance; often minimal or waived on a HELOC, though early-closure fees are common.

Both products are constrained by loan-to-value, and the limits differ.

Cash-out refinances are generally capped at 80% LTV on a primary residence, and lower on investment properties. On a $450,000 home that is $360,000 of total loan, so an existing $250,000 balance leaves roughly $104,000 of accessible cash after closing costs.

HELOCs commonly allow a combined loan-to-value up to 85%, and occasionally 90% for strong borrowers. The same home supports $382,500 of combined debt, or about $132,500 of draw.

Neither limit is negotiable, and both are assessed on a fresh appraisal rather than on what you think the house is worth. An appraisal coming in low is the most common way one of these deals falls apart.

VA cash-out refinances can reach 100% LTV for eligible borrowers, which is a genuinely distinctive benefit and worth checking if you qualify.

Both options are secured on your home. That is what makes the rates low and it is what makes the downside serious: default on either and you can lose the house.

This is the main argument against the common advice to consolidate credit card debt into home equity. The rate falls from perhaps 22% to 9%, which is real, but you have converted unsecured debt into secured debt. Credit card default damages your credit; mortgage default takes your home.

It also does nothing about the behaviour that produced the debt. A meaningful share of people who consolidate run the cards back up within a couple of years and end up with both.

The uses that hold up well: a renovation that adds value, a genuine emergency reserve you draw only if needed, or bridging a known gap with a known repayment source.

On tax, interest is deductible only when the borrowing is used to buy, build or substantially improve the home securing the loan. Borrowing against your house to pay off a car or fund a holiday is not deductible, and the deduction only helps at all if you itemise — which most households no longer do.
