Compound Interest Calculator Canada
Calculate how your money grows with compound interest. This calculator helps Canadian investors understand:
The Compound Interest Formula
A = P(1 + r/n)^(nt)
- A = Final amount
- P = Principal (initial investment)
- r = Annual interest rate (decimal)
- n = Compounding frequency per year
- t = Time in years
Historical Average Returns (Canada) - January 2026
- S&P/TSX Composite (25-year avg): ~8% p.a. (total return including dividends)
- U.S. Equities (S&P 500): 10-11% p.a.
- Canadian Bonds: 4-5% p.a.
- GICs: 3.5-3.85% p.a. (current rates)
- High Interest Savings: 3-4% p.a.
The Rule of 72
A quick way to estimate how long it takes to double your money: 72 ÷ interest rate = years to double. At 7% return, money doubles approximately every 10.3 years.
Compounding Frequency Impact
More frequent compounding leads to higher returns. For a $10,000 investment at 7% over 10 years:
- Annual compounding: $19,672
- Monthly compounding: $20,097
- Daily compounding: $20,138
Registered Account Limits (2026)
- TFSA contribution limit 2026: $7,000 ($109,000 cumulative since 2009)
- RRSP contribution limit 2026: $33,810 (or 18% of earned income)
- FHSA contribution limit: $8,000/year ($40,000 lifetime)
- RESP lifetime limit: $50,000 per beneficiary
- CDIC insurance: $100,000 per eligible account
Tax Considerations
- TFSA: Contributions not deductible, growth and withdrawals tax-free
- RRSP: Contributions tax-deductible, growth tax-deferred, withdrawals taxed as income
- FHSA: Contributions tax-deductible, growth and qualifying withdrawals tax-free
- Non-registered: Interest taxed at marginal rate, capital gains 50% inclusion rate

What is Compound Interest?
Compound interest is the phenomenon where your investment earns returns, and those returns themselves earn returns, creating a snowball effect that accelerates wealth accumulation over time. Unlike simple interest which only earns on your principal, compound interest creates exponential growth.
Albert Einstein allegedly called compound interest “the eighth wonder of the world,” noting that “he who understands it, earns it; he who doesn’t, pays it.” This fundamental principle is the difference between financial struggle and financial freedom for most Australians.
The magic happens because each period’s interest becomes part of the principal for the next period. Over decades, this effect becomes dramatic—a $10,000 investment at 8% grows to $46,600 in 20 years and $100,600 in 30 years. The longer you wait, the more powerful compound interest becomes.
Formula
A = P(1 + r/n)^(nt)
Where A = final amount, P = principal, r = annual interest rate, n = compounding frequency, t = time in years
Exponential Growth
Your money grows faster over time as interest earns interest, creating a powerful snowball effect that accelerates wealth accumulation.
Regular Contributions
Small, consistent monthly contributions can dramatically boost your final investment value through the power of dollar-cost averaging.
Time Advantage
Starting early gives you the greatest advantage in building wealth. Time is your most valuable asset in the compound interest equation.
Master the Art of Investing
Learn the fundamental principles of compound interest and how to apply them to build lasting wealth over time.
The Power of Compounding
Albert Einstein reportedly called compound interest 'the eighth wonder of the world.' Your money earns money, which then earns more money.
Time is Your Best Friend
The earlier you start, the less you need to save monthly to reach your goals. A 25-year-old needs to save less than half of what a 35-year-old needs for the same retirement goal.
Dollar-Cost Averaging
Regular contributions help smooth out market volatility. You buy more shares when prices are low and fewer when prices are high.
Set Clear Goals
Having specific financial goals helps you stay motivated and make informed decisions about how much to save and invest.
