In plain English, what is a line of credit on your house?

A line of credit on your house is a revolving credit facility backed by your home equity. The bank approves a maximum amount, and you draw from it as you need money. You pay interest only on what you have actually borrowed. The rate is variable, meaning it can go up or down over time.

Which is better: a home equity loan or a line of credit?

Neither is universally better. A home equity loan is better when you know exactly how much you need and want predictable fixed payments. A line of credit is better when you are spending in phases, do not know the exact total, or want to keep the option available without drawing immediately.

Home Equity Loan vs. Line of Credit
The Plain-English Version

Last verified: April 2026

A promise before we start: This page has zero jargon. Every term is explained where it appears. The only acronym we use is HELOC, and we will tell you exactly what it means in the next sentence.

First: what is equity?

Equity is what part of your home you own outright. If your home is worth $400,000 and you still owe $200,000 on your mortgage, you have $200,000 in equity. That equity is real money that belongs to you. Banks will let you borrow against it.

What "equity" means in plain English: Your home's current market value, minus everything you still owe on it. The remainder is yours.

Why do banks let you borrow against your home?

Because your home is worth real money and sits there as security. The bank knows that if you stop paying, it can sell your home to get its money back. That security is why the interest rate on a home equity loan or a home equity line of credit is much lower than on a credit card. The bank is taking less risk, so it charges you less.

What "collateral" means: Collateral is the thing you put up as security for a loan. In this case, it is your home. If you cannot pay, the lender can take the collateral. That is the most important risk to understand.

The two ways to borrow against your home

There are two main products. They are similar in that both use your home as security, but they work differently day to day.

Option 1

The Loan (Home Equity Loan)

They hand you a cheque for, say, $50,000 on day one. You start paying it back the next month. The same payment, every single month, until it is done. If the term is 15 years, you make 180 payments and then you are finished.

The interest rate is fixed. That means it will never change for the life of the loan, no matter what happens with interest rates in the wider economy. Simple, predictable, easy to budget.

Option 2

The Line (HELOC = Home Equity Line of Credit)

They open a "pot" of, say, $50,000 that you can dip into whenever you want. You take $5,000 this year. You take another $10,000 next year. You let it sit untouched for three years. You only pay interest on what you have actually taken out. Not on the full $50,000, just on what you have drawn.

It works like a credit card, but much cheaper, because your house is standing behind it as security.

The interest rate is variable. That means it can go up or down over time, depending on what happens to interest rates in the economy. More on that in the risks section below.

HELOC (pronounced HEE-lock) stands for Home Equity Line of Credit. That is all it is. A line of credit, secured by your home equity. If you have been nervous about the acronym, you can now let that go.

When the loan makes more sense

You know exactly how much you need, and you need it now. A contractor has given you a fixed quote of $42,000 for a kitchen renovation. You do not want the rate to change. You want to know your exact monthly payment for the next 12 years. That is when the home equity loan is the better choice.

Fixed contractor bid for home renovation
One-time medical expense
Paying off a specific credit card balance
Any situation where you know the exact sum needed and want to lock in your payments

When the line makes more sense

You do not know yet how much you will need, or you want the money to be available over time. Paying college tuition over four years is a perfect example. You do not want to borrow $80,000 on day one and pay interest on all of it for four years when you only need $20,000 this year. With a line of credit, you draw $20,000 this year, and pay interest only on that.

College tuition paid in instalments over several years
Renovation that happens in stages over 12 to 18 months
An emergency fund you want available but hope never to use
Any situation where the total is uncertain or spending is spread over time

The honest risks

Risk 1: Your home is collateral. Both products are secured by your home. If you stop making payments, the lender can foreclose. That means they can force the sale of your home to get their money back. This is the biggest risk, and it is important to say it plainly rather than burying it in small print.

Risk 2: The line's rate can go up. The home equity line of credit (HELOC) has a variable rate. If the prime rate rises by 2%, your HELOC rate rises by 2%. On a $50,000 balance, that is $1,000 a year more in interest. It is not guaranteed to rise, but you should be comfortable with that possibility before you borrow.

What "variable rate" means: The interest rate is tied to the prime rate, which is set by banks and moves when the Federal Reserve changes its benchmark rate. Your rate is the prime rate plus a fixed "margin" set by your lender (for example, prime + 1.5%). When prime goes up, your rate goes up. When prime goes down, your rate goes down.

Risk 3: Payment shock when the line ends. During the first 10 years (the "draw period"), you can borrow and you make interest-only payments, which are relatively low. When the draw period ends, you can no longer borrow, and you have to start repaying the full balance over 20 years. Your monthly payment can jump significantly. On a $50,000 balance: interest-only at 8.6% is about $358/month. Full repayment over 20 years is about $438/month. That jump is called payment shock, and it catches some people off guard.

Questions we hear most often

In plain English, what is a home equity loan?

A home equity loan is when a bank lends you a fixed sum of money, secured by the equity in your home. You get all the money on day one and repay it in equal fixed monthly payments over a set number of years. The rate does not change.

In plain English, what is a HELOC (line of credit on your house)?

A HELOC is a revolving credit facility backed by your home equity. The bank approves a maximum amount. You draw from it as needed and pay interest only on what you have actually borrowed. The rate is variable.

Which is better: the loan or the line?

Neither is universally better. Choose the loan when you know exactly how much you need and want predictable fixed payments. Choose the line when you are spending in phases, do not know the total yet, or want the option available without drawing immediately.

What does 'variable rate' mean in plain English?

A variable rate is an interest rate that can change over time. For HELOCs, it is usually tied to the prime rate. When the prime rate goes up, your monthly interest bill goes up. When it goes down, your bill goes down.
