Results are estimates based on the inputs and assumptions shown. Investment returns, dividends, interest rates, tax rules, contribution room, and government benefit amounts can change.

Quick answer
The calculator shows what steady contributions could become after fees and inflation assumptions. For Canadian planning, use the result as step one, then compare whether the same plan belongs in a TFSA, RRSP, FHSA, or taxable account.
Projected balance
$250,949
Investment growth
$120,949
Real value after inflation
$168,272
The gap between contributed dollars and ending balance is your compounding effect.
What this helps answer
Whether your current savings plan is enough for retirement, a long-term TFSA strategy, or a general investing target.
Best next comparison
Compare a compounding plan with registered-account choices like TFSA, RRSP, or FHSA so taxes and contribution room are not ignored.
Good default assumption
If you are unsure, start with a 5% to 6% long-run return before inflation and keep fees below 0.5% where possible.
Compound interest in a TFSA
If you are searching for a compound interest calculator in Canada, there is a good chance the real question is about TFSA growth. The math engine is the same either way, but the account wrapper changes what happens to the gains. A TFSA lets the balance compound without tax on the growth or on qualifying withdrawals, which is why the same monthly contribution plan can be more valuable there than in a taxable account.
Use this calculator to size the savings engine first. Then check whether the plan belongs in a TFSA calculator, whether the TFSA vs RRSP decision changes the account choice, and which TFSA ETF mix and broker workflow fit the plan.
Pressure-test a monthly investing plan before you choose the account wrapper or the provider.
Long-term ETF investing where tax-free growth and withdrawal flexibility both matter.
Run the same contribution plan through TFSA and RRSP math before you pick a broker or ETF.
Real Canadian scenario
Assume a 30-year-old Canadian investor starts with $10,000, adds $500/month, tests a 20-year horizon, and wants to see how fees and inflation change the headline number.
$250,949 projected nominal balance and $168,272 inflation-adjusted balance under the current inputs.
The gap between nominal and inflation-adjusted values is the part many people miss. The plan may look large in future dollars but feel smaller after purchasing power is considered.
Limitation: Returns are smoothed and do not model market crashes, contribution pauses, taxes, product changes, or investor behaviour.

This calculator applies a monthly compounding model using your opening amount, monthly contributions, expected annual return, annual fee drag, and an inflation adjustment. It is designed for educational planning, not account-specific forecasting.

Checked against official Canadian source material where applicable; not reviewed by a licensed financial advisor, accountant, mortgage broker, or tax professional unless explicitly stated.
Educational estimate only. Real returns vary year to year, and taxes may apply depending on whether you invest inside a TFSA, RRSP, FHSA, or non-registered account.
How to use this compound interest calculator
This page works best when you use it to answer a practical planning question, not just to generate the biggest possible future number. Start with your current balance, realistic monthly contribution, and a conservative expected return. Then compare that baseline against a second scenario with lower fees, higher contributions, or a longer timeline. That usually tells you more than moving the return slider to an optimistic number.
For Canadians, the next step is usually deciding where this compounding should happen. A TFSA, RRSP, FHSA, or taxable account can lead to very different after-tax outcomes even if the growth curve looks similar. Use this calculator to understand the savings engine first, then compare it against account-specific tools before making the actual contribution decision.
What this page helps you decide
Many people overestimate what a perfect annual return will do and underestimate how much steady monthly contributions drive the result. This calculator makes that tradeoff visible by separating contributed dollars, investment growth, and inflation-adjusted value. If a plan only works under an aggressive return assumption, it is probably too fragile for real-world planning.
It also helps you pressure-test fee drag. Even a small annual fee difference can remove a meaningful amount of wealth over a long horizon. If you are comparing brokers, robo-advisors, or ETF options, use this page as the neutral planning baseline before provider marketing or sign-up bonuses start shaping the decision.
For TFSA-focused readers, the cleanest sequence is usually: calculate the compounding plan here, compare the account decision with TFSA vs RRSP, then narrow the ETF and broker choice once the monthly contribution target feels realistic.
Use nominal returns to see the account balance you may actually observe, and compare the inflation-adjusted line to understand future purchasing power.
Even a small annual fee compounds over time. Modeling fee drag keeps long-range projections closer to reality.
If you are deciding where to invest, compare this result against TFSA and RRSP calculators, then use the TFSA ETF and broker guides if tax-sheltered investing still looks like the right fit.
Example calculation
With $10,000 invested today, $500 added each month, a 6.0% expected return, and 0.4% annual fee drag, this scenario projects about $250,949 after 20 years. Of that total,$130,000 comes from contributions and $120,949comes from modeled investment growth.
Common mistakes
FAQ
Test a lower, base, and higher range instead of relying on one number. The calculator is most useful when the plan still works under a weaker-return scenario.
You can use it as the growth baseline, then open the TFSA calculator to check contribution room and account-specific constraints before contributing.
No. It uses a fixed annual return, fee, and inflation assumption. Real portfolios move unevenly, so treat the result as a planning range rather than a guarantee.
There is no guaranteed number. For a cautious long-term scenario, many people test several ranges, such as lower-return, base-case, and optimistic assumptions, then check whether the plan still works if returns are weaker.
Fees reduce the return that actually compounds. A small annual fee difference can become meaningful over long periods, especially when contributions continue for many years.

Why this may fit after the growth plan
Provider terms, promotions, eligibility, and fees can change. Verify details with the provider before opening or funding an account.
Compare providers next
Once you know the contribution plan, fee sensitivity, and time horizon, it becomes easier to compare brokers and investing apps without getting distracted by marketing first.
Best for broad shortlist
Use the broader provider guide if you are still comparing the main investing app options.
Best for head-to-head
Use the main comparison if those two platforms are your most likely next step.
Best if using registered accounts
Use the TFSA shortlist once you know tax-sheltered investing is likely the right home for the plan.
