Is it better to max out RRSP or pay off mortgage?

It depends on your mortgage rate, marginal tax rate, and expected investment returns. Generally, if your marginal tax rate is high (over 40%) and your mortgage rate is low (under 5%), RRSP wins. The tax refund can also be applied to your mortgage for a hybrid approach.

Should I use my RRSP refund to pay down my mortgage?

This is often the best hybrid strategy. Contribute to your RRSP, get the tax refund, and apply the refund to your mortgage. You get the tax deduction benefits plus mortgage reduction — best of both worlds.

What if I''m in a low tax bracket?

If you''re in a low tax bracket (under 30%), paying down the mortgage may be better. You''re not getting much tax refund from RRSP, and mortgage interest is paid with after-tax dollars. Consider TFSA instead of RRSP in low-income years.

RRSP vs Paying Down Your Mortgage: Which Is Smarter? (2026)

This is the most common financial dilemma for Canadian homeowners, and the math usually favours the RRSP — but not always. In a 40% tax bracket, a $10,000 RRSP contribution effectively costs you $6,000 after the refund, while a $10,000 mortgage payment uses the full $10,000 of after-tax dollars. The hybrid approach — contribute to your RRSP and apply the refund to your mortgage — turns $10,000 into $14,000 of total financial benefit. But if your mortgage rate exceeds 6–7% or you’re in a low tax bracket, the guaranteed return from paying down debt may beat the uncertain market returns in your RRSP.

The Key Factors

Factor	Favors RRSP	Favors Mortgage
High marginal tax rate	✓
Low mortgage rate	✓
Long time to retirement	✓
Employer RRSP match	✓
High mortgage rate		✓
Low tax bracket		✓
Near retirement		✓
Risk averse		✓

The Math Comparison

Scenario: $10,000 to Allocate

Option	RRSP	Mortgage
Amount invested/paid	$10,000	$10,000
Tax refund (40% bracket)	$4,000	$0
Effective cost	$6,000	$10,000

10-Year Comparison

Assumptions:

$10,000 annual contribution/payment
40% marginal tax rate
6% investment return
5% mortgage rate

After 10 Years	RRSP	Mortgage Paydown
Amount contributed	$100,000	$100,000
Tax refunds received	$40,000	$0
Net cost to you	$60,000	$100,000
RRSP balance (6% return)	~$139,000	N/A
Interest saved	N/A	~$28,000
Mortgage reduction	N/A	$128,000

The Hybrid Approach

Year	RRSP Contribution	Tax Refund	Apply to Mortgage
1	$10,000	$4,000	$4,000
2	$10,000	$4,000	$4,000
…	…	…	…
10	$10,000	$4,000	$4,000
Total	$100,000	$40,000	$40,000

Result: RRSP grows AND mortgage reduced by $40,000.

When RRSP Wins

High Tax Bracket Advantage

Tax Bracket	RRSP Refund per $10K	Effective Cost
20%	$2,000	$8,000
30%	$3,000	$7,000
40%	$4,000	$6,000
50%	$5,000	$5,000

Higher bracket = bigger RRSP advantage.

Employer Match

Scenario	RRSP Value
You contribute $5,000	$5,000
Employer matches 100%	+$5,000
Total RRSP	$10,000
Instant return	100%

Always take employer match first — it’s free money.

An employer RRSP match is a 50–100% guaranteed return on day one, which no mortgage paydown or market investment can replicate. If your employer matches 100% up to 5% of your salary, that’s $5,000 of free money on a $100,000 income — skipping it to pay down your mortgage is leaving money on the table. Max the match first, then decide between additional RRSP contributions and extra mortgage payments based on your tax bracket and mortgage rate.

Expected Returns vs Mortgage Rate

Investment Return	Mortgage Rate	Winner
7%	5%	RRSP
7%	7%	Tie (risk-adjusted: mortgage)
5%	6%	Mortgage

When Mortgage Wins

Low Tax Bracket

Tax Bracket	RRSP Advantage
Under 25%	Minimal — consider TFSA or mortgage
25-35%	Close call
Over 35%	RRSP usually wins

High Mortgage Rate

Mortgage Rate	Guaranteed Return
3%	Pay 3% guaranteed
5%	Pay 5% guaranteed
7%	Pay 7% guaranteed — beats most investments

Near Retirement

Years to Retirement	Consideration
20+ years	RRSP has time to compound
10-20 years	Either can work
Under 10 years	Debt-free in retirement has value

Peace of Mind

Factor	Value
Guaranteed return	Mortgage rate
No market risk	Sleep better
Debt-free feeling	Psychological benefit
Flexibility	Lower payment = less stress

Decision Framework

Step 1: Get Free Money First

Priority	Action
1	Employer RRSP match — always
2	Then decide RRSP vs mortgage

Step 2: Consider Tax Bracket

Your Bracket	Recommendation
High (40%+)	RRSP likely better
Medium (30-40%)	Do the math, hybrid approach
Low (under 30%)	Consider TFSA or mortgage

Step 3: Compare Rates

If retirement horizon is long…
Expected return > mortgage + 1-2%	RRSP
Expected return ≤ mortgage rate	Mortgage

Step 4: Consider Risk Tolerance

If you…	Then
Can stomach market volatility	RRSP may be fine
Prefer certainty	Mortgage paydown

Hybrid Strategy: The Best of Both

How It Works

Step	Action
1	Maximize RRSP contribution
2	Claim tax deduction
3	Apply refund to mortgage
4	Repeat annually

Example Calculation

Annual Amount	Allocation
Available	$15,000
To RRSP	$15,000
Tax refund (40%)	$6,000
To mortgage	$6,000
Total deployed	$21,000

TFSA as the Alternative

When TFSA Beats Both

Situation	Why TFSA
Low tax bracket now	No RRSP refund benefit
Expect higher income later	Save RRSP room
Want accessibility	No withdrawal restrictions
Below TFSA limit	Tax-free growth

Order of Priority

Priority	Account	When
1	Employer RRSP match	Always
2	High-interest debt	Always
3	TFSA	Low tax bracket
3	RRSP + refund to mortgage	High tax bracket
4	Extra mortgage payments	After above

The Bottom Line

If you’re in a 35%+ tax bracket with a mortgage rate under 5–6%, the RRSP plus refund-to-mortgage hybrid strategy almost always wins. Contribute to the RRSP, claim the deduction, and direct every refund dollar to your mortgage as a lump-sum prepayment. If you’re in a lower bracket, consider maxing your TFSA first and using extra cash for mortgage prepayments. The worst choice is doing nothing while you deliberate — both options build wealth, and even a split approach puts you ahead of most Canadians.
