Reverse Mortgage - Compound Interest

Reverse Mortgage Interest in Canada - How the Balance Grows Over Time

With a reverse mortgage, no payments are made. Every month, interest is added to the balance. The next month, interest is charged on that larger balance. This compound interest accelerates the growth of the outstanding balance over time - understanding this before you commit is essential.

The basics

Why compounding matters more for a reverse mortgage

With a standard mortgage, you make monthly payments that cover the interest and reduce the principal. The balance goes down over time. With a reverse mortgage, no payments are made. Every month, interest is added to the balance. The next month, interest is charged on that larger balance. This is compound interest - interest on interest.

This is not a hidden risk. It is the fundamental structure of a no-payment loan. But many borrowers do not fully understand how significant the growth can be over a long time horizon.

Illustrative examples at annual compounding: $200,000 borrowed at 7% grows to approximately $280,510 after 5 years, $393,430 after 10 years, and $551,840 after 15 years. At 8%, the same amount grows to approximately $293,870, $431,785, and $634,455 at those same intervals. These are illustrative only - actual compounding is typically semi-annual for fixed rates.

Who it's for

What affects how fast the balance grows

The rate of balance growth depends on several factors you can influence before committing.

Interest rate - every 0.5% difference compounds significantly over 15 years

Compounding frequency - semi-annual for fixed rates is the typical Canadian standard

Initial borrowing amount - borrowing less means slower balance growth

Whether you make voluntary payments - some products allow optional payments to slow growth

Property value appreciation - if the home appreciates, remaining equity is preserved

Fixed vs variable rate - variable rates can change and affect the growth trajectory

When the mortgage starts vs when the home is sold

Whether you borrow in installments vs a lump sum

Ask HB Mortgage Centre to model your specific borrowing amount, current lender rate, and compounding frequency before making a decision. Illustrative numbers are for general understanding only.

How it works

What to review before you commit to a reverse mortgage

Request a balance projection

Ask us to model the projected outstanding balance at 5, 10, and 15 years at the current lender rate. This is the most important number in the conversation.

Understand compounding frequency

Confirm whether the rate is compounded monthly, semi-annually, or annually. Semi-annual is standard for Canadian fixed rate mortgages. The lender's commitment letter specifies this.

Consider borrowing less

The less you borrow, the slower the balance grows. If you only need a portion of your maximum qualifying amount, borrowing less reduces the long-term cost significantly.

Ask about voluntary payments

Some reverse mortgage products allow voluntary partial payments. If you can make occasional payments, this can meaningfully slow the balance growth.

Review with your lawyer

Independent legal advice is required before any reverse mortgage closes. Your lawyer should review the full cost of borrowing projection, not just the immediate terms.

Estate impact

The longer the mortgage runs, the more equity is consumed

The estate receives what is left after the reverse mortgage balance and costs are repaid from the sale proceeds. If the property has appreciated significantly, there may still be substantial equity remaining. If the property has been flat or declined in value while the balance has grown, there may be less. Reviewing the long-term balance projections alongside expected property value trends is essential - and this conversation should happen before you commit, not after.

Why a broker

We model the balance before you decide

Before you commit to any reverse mortgage, we run the balance projections at current rates for your specific borrowing amount and compounding schedule. This is the conversation that matters most - not the initial qualifying amount or the rate headline.

We also compare the projected balance trajectory across both CHIP (HomeEquity Bank) and Equitable Bank products, where available, so you can see whether a rate difference between products has a meaningful long-term impact on your estate.

Understanding how the balance grows over time is the most important part of the reverse mortgage decision. We show you the numbers before you sign.

FAQ

Frequently Asked Questions - Reverse Mortgage Compound Interest

How does reverse mortgage interest compound in Canada?+

Interest is added to the outstanding balance at regular intervals - typically semi-annually for fixed rates in Canada. Future interest is then charged on the larger balance. This compounding accelerates the balance growth the longer no payments are made.

Can I make payments on a reverse mortgage to slow the balance growth?+

Some reverse mortgage products allow voluntary partial payments. Confirm whether the specific product you are considering allows this, and whether there are any restrictions or penalties. Ask your broker before committing.

How does compound interest affect my estate?+

The longer the reverse mortgage runs, the more of your equity is consumed by accumulated interest. The estate receives what is left after the balance is repaid from the sale proceeds. If property values have risen significantly, there may still be meaningful equity. If values have been flat and the balance has grown significantly, there may be less.
