The True Cost of a Reverse Mortgage Over 10 Years in Ontario

"How much will a reverse mortgage really cost me over 10 years?" It is the single most important question Ontario homeowners ask before signing — and the answer depends entirely on how much you borrow, the interest rate, and what alternatives you are comparing against. This guide gives you the full picture with year-by-year compound interest tables, a HELOC side-by-side, and a realistic breakdown of what downsizing actually costs in Ontario.

How Reverse Mortgage Interest Compounds in Ontario

Before diving into the numbers, it is essential to understand the mechanism. A reverse mortgage does not require monthly payments. Instead, interest is added to your outstanding balance and compounds semi-annually, the same way a traditional Canadian mortgage works. This is regulated by OSFI (the Office of the Superintendent of Financial Institutions), which oversees federally regulated lenders including HomeEquity Bank (the provider behind the CHIP Reverse Mortgage) and Equitable Bank.

The effect of compounding means your total cost accelerates over time. In Year 1, the cost is relatively modest. By Year 10, the accumulated interest can be substantial — but whether that cost is reasonable depends on your alternatives.

According to the Financial Consumer Agency of Canada (FCAC), borrowers should request a written projection of their balance at 5, 10, and 15 years before finalizing any reverse mortgage agreement. This is standard practice and every lender is expected to provide it.

Year-by-Year Compound Interest: $100,000 Borrowed

The following table assumes a lump-sum advance of $100,000 with no voluntary payments made during the 10-year period. Interest compounds semi-annually.

Year	Balance at 7.50%	Interest Cost (Cumulative)	Balance at 8.50%	Interest Cost (Cumulative)
0	$100,000	$0	$100,000	$0
1	$107,641	$7,641	$108,681	$8,681
2	$115,862	$15,862	$118,115	$18,115
3	$124,710	$24,710	$128,362	$28,362
4	$134,237	$34,237	$139,497	$39,497
5	$144,499	$44,499	$151,600	$51,600
6	$155,554	$55,554	$164,756	$64,756
7	$167,465	$67,465	$179,058	$79,058
8	$180,302	$80,302	$194,608	$94,608
9	$194,136	$94,136	$211,517	$111,517
10	$209,046	$109,046	$229,905	$129,905

At 7.50%, borrowing $100,000 costs approximately $109,046 in interest over 10 years. At 8.50%, the cost rises to roughly $129,905. The difference between those two rates — just one percentage point — amounts to over $20,000.

This is why working with an experienced broker like Rick Sekhon matters: securing the lowest available rate from lenders such as CHIP, Equitable Bank, Bloom Financial, or Home Trust can save tens of thousands of dollars over the life of the loan.

Year-by-Year Compound Interest: $200,000 Borrowed

Year	Balance at 7.50%	Interest Cost (Cumulative)	Balance at 8.50%	Interest Cost (Cumulative)
0	$200,000	$0	$200,000	$0
1	$215,282	$15,282	$217,362	$17,362
2	$231,724	$31,724	$236,230	$36,230
3	$249,420	$49,420	$256,724	$56,724
4	$268,474	$68,474	$278,994	$78,994
5	$288,998	$88,998	$303,200	$103,200
6	$311,108	$111,108	$329,512	$129,512
7	$334,930	$134,930	$358,116	$158,116
8	$360,604	$160,604	$389,216	$189,216
9	$388,272	$188,272	$423,034	$223,034
10	$418,092	$218,092	$459,810	$259,810

At the $200,000 level, the 10-year interest cost at 7.50% is approximately $218,092 — essentially doubling the original loan balance. This is significant, but it must be evaluated against the alternatives.

Year-by-Year Compound Interest: $300,000 Borrowed

Year	Balance at 7.50%	Interest Cost (Cumulative)	Balance at 8.50%	Interest Cost (Cumulative)
0	$300,000	$0	$300,000	$0
1	$322,923	$22,923	$326,043	$26,043
2	$347,586	$47,586	$354,345	$54,345
3	$374,130	$74,130	$385,086	$85,086
4	$402,711	$102,711	$418,491	$118,491
5	$433,497	$133,497	$454,800	$154,800
6	$466,662	$166,662	$494,268	$194,268
7	$502,395	$202,395	$537,174	$237,174
8	$540,906	$240,906	$583,824	$283,824
9	$582,408	$282,408	$634,551	$334,551
10	$627,138	$327,138	$689,715	$389,715

At $300,000 borrowed, the 10-year cost at 7.50% is approximately $327,138. This is a large number on its own — but context matters. If your home is worth $800,000 today and appreciates even modestly at 2% annually, it will be worth roughly $975,000 in 10 years. The remaining equity after repaying $627,138 would still be approximately $348,000.

The Rate Matters More Than You Think

Amount Borrowed	10-Year Cost at 7.50%	10-Year Cost at 8.50%	Difference
$100,000	$109,046	$129,905	$20,859
$200,000	$218,092	$259,810	$41,718
$300,000	$327,138	$389,715	$62,577

A single percentage point difference in rate means $20,000 to $62,000 more in interest over a decade. This is why Rick Sekhon shops multiple lenders — including CHIP, Equitable Bank, Bloom Financial, and Home Trust — to find you the best rate available.

Comparing to the True Cost of a HELOC Over 10 Years

Many Ontario homeowners assume a HELOC is cheaper because the interest rate is lower. In early 2026, HELOC rates are approximately prime + 0.5%, which works out to roughly 5.20%. But a HELOC requires monthly interest payments — and for a senior on a fixed income, those payments are a real cost.

Factor	HELOC ($200,000 at 5.20%)	Reverse Mortgage ($200,000 at 7.50%)
Monthly payment required	~$867/month	$0
Total interest paid over 10 years	~$104,040 (if interest-only)	~$218,092
Total cash out of pocket over 10 years	~$104,040	$0
Risk if payments missed	Lender can demand repayment; potential forced sale	None — no payments required
Income qualification required	Yes	No
Credit score required	Yes (typically 680+)	No

The HELOC is cheaper in total interest — by roughly $114,000 in this example. But you must pay $867 every single month for 10 years. That is $104,040 out of your retirement income. For a senior living on CPP and OAS totalling $2,500/month, committing $867/month to HELOC interest leaves just $1,633 for everything else.

According to Statistics Canada, the median total income for Canadians aged 65 and over was approximately $32,000 per year (roughly $2,667/month) in 2023. A HELOC payment of $867/month would consume over 32% of that income.

The reverse mortgage costs more in total interest but requires zero cash outflow. For many Ontario retirees, the no-payment certainty is worth the premium.

Comparing to the True Cost of Downsizing

The other common alternative is selling the home and downsizing. Ontario homeowners often assume this is the cheapest option — but the transaction costs are significant and frequently underestimated.

Real Costs of Selling and Downsizing in Ontario

Cost Item	Typical Amount	Notes
Real estate agent commission	4–5% of sale price	On an $800,000 home: $32,000–$40,000
Legal fees (sale + purchase)	$2,500–$5,000	Two transactions required
Land transfer tax (on new purchase)	$6,475–$12,950+	Ontario LTT on $500K–$700K purchase
Toronto municipal LTT (if applicable)	$5,725–$9,475+	Additional tax in Toronto
Moving costs	$2,000–$5,000	Professional movers for a full household
Home staging and repairs for sale	$3,000–$10,000	Painting, minor renovations, staging
Adjustments and incidentals	$1,000–$3,000	Utility adjustments, storage, etc.
Total estimated cost	$47,000–$85,000+	Before any emotional or lifestyle costs

On a home worth $800,000, selling and purchasing a smaller home at $550,000 could cost $50,000 to $85,000 in direct transaction expenses alone. That is money gone permanently — unlike reverse mortgage interest, which only accrues against your remaining equity.

10-Year Comparison Summary

Option	Total Cost Over 10 Years	Monthly Cash Required	Stay in Home?
Reverse mortgage ($200K at 7.50%)	~$218,092 (interest)	$0	✓ Yes
HELOC ($200K at 5.20%)	~$104,040 (interest paid)	~$867/month	✓ Yes
Sell and downsize	~$50,000–$85,000 (transaction)	Varies (new housing costs)	✗ No

Each option has a different cost structure. The reverse mortgage costs the most in total interest but demands nothing month to month. The HELOC costs less total but requires steady cash flow. Downsizing has a large upfront cost and removes you from your home permanently.

What About Home Appreciation?

Ontario home values have historically appreciated over long periods. While past performance does not guarantee future results, even modest appreciation can offset a significant portion of reverse mortgage interest.

Home Value Today	Annual Appreciation	Value in 10 Years	Reverse Mortgage Balance ($200K at 7.50%)	Remaining Equity
$600,000	2%	$731,000	$418,092	$312,908
$800,000	2%	$975,000	$418,092	$556,908
$800,000	3%	$1,075,000	$418,092	$656,908
$1,000,000	2%	$1,219,000	$418,092	$800,908

According to the Canadian Real Estate Association (CREA), Ontario home prices have averaged approximately 4–5% annual appreciation over the past 25 years, though with significant year-to-year variation. Even a conservative 2% assumption shows substantial equity preservation.

The key insight: even with a $200,000 reverse mortgage compounding for 10 years, most Ontario homeowners retain significant equity in their property. The CMHC no-negative-equity guarantee (applicable to CHIP) ensures borrowers never owe more than the home is worth.

Strategies to Reduce Your 10-Year Cost

Working with Rick Sekhon, you can employ several strategies to minimize the true cost:

1. Take only what you need. Every dollar borrowed compounds. If you need $150,000 but qualify for $250,000, borrow $150,000.
2. Make voluntary payments. Most reverse mortgages allow annual prepayments of 10–20% without penalty. Even small payments reduce the compounding base.
3. Shop rates aggressively. Rick compares rates across CHIP, Equitable Bank, Bloom Financial, and Home Trust to find the best available rate.
4. Consider a partial lump sum plus scheduled advances. Some lenders offer scheduled disbursements, meaning you only borrow as you need — reducing the average balance that compounds.
5. Lock in during rate dips. Fixed-rate terms protect you from future increases. Monitor current reverse mortgage rates in Ontario.

FAQ

Is the interest on a reverse mortgage tax-deductible? Generally no, unless the borrowed funds are used for income-producing purposes (such as investing in a rental property). The CRA does not allow deduction of interest on personal-use borrowing. Consult a tax professional for your specific situation. See our full guide on CRA tax treatment of reverse mortgages.

Can I pay down the reverse mortgage early to reduce the 10-year cost? Yes. Most lenders allow annual voluntary prepayments — typically 10% to 20% of the original principal — without triggering a prepayment penalty. Any payment reduces the balance that compounds going forward, significantly lowering total cost.

What happens if rates drop after I lock in? If you are in a fixed-rate term with CHIP or Equitable Bank and rates decline, you can potentially refinance at the lower rate — though prepayment penalties may apply. Rick Sekhon can model whether the savings outweigh the penalty cost. FSRAO requires that all penalty terms be disclosed before closing.

Does the 10-year cost include closing fees? The tables above show interest cost only. Upfront closing costs (appraisal, legal fees, setup fee) typically add $2,000–$4,000 and are usually deducted from the initial advance. For a complete fee breakdown, see our reverse mortgage closing costs guide.

Will I still have equity left after 10 years? In the vast majority of cases, yes. The CHIP no-negative-equity guarantee ensures you will never owe more than the fair market value of your home at the time of sale. Most Ontario homeowners retain substantial equity even after 10 years of compounding.
