Quick answer

Use this as the growth baseline before choosing TFSA, RRSP, or FHSA

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

Growth over time

The gap between contributed dollars and ending balance is your compounding effect.

Net annual return: 5.6%

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

Why the TFSA version of the same growth plan can matter more

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.

Best use of this page

Pressure-test a monthly investing plan before you choose the account wrapper or the provider.

Strong TFSA use case

Long-term ETF investing where tax-free growth and withdrawal flexibility both matter.

Best next comparison

Run the same contribution plan through TFSA and RRSP math before you pick a broker or ETF.

Real Canadian scenario

Canadian investor testing a $500 monthly ETF habit

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.

Inputs used

  • Opening amount: $10,000
  • Monthly contribution: $500
  • Return assumption: 6% before a 0.4% annual fee
  • Inflation assumption: 2%
  • Time horizon: 20 years

Result and interpretation

$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.

How this calculator works: compound interest assumptions

Last updated: April 29, 2026

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.

Assumptions

  • Returns are smoothed into a constant monthly rate and do not reflect market volatility.
  • Monthly contributions are added at the end of each month.
  • Annual fees reduce the expected annual return before monthly growth is calculated.
  • Inflation is shown as a separate real-value view so nominal and purchasing-power outcomes can be compared.

Sources and review

How to use this compound interest calculator

Model the contribution plan before you choose the account

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

Savings behavior usually matters more than a perfect return guess

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.

Should I use nominal or real returns?

Use nominal returns to see the account balance you may actually observe, and compare the inflation-adjusted line to understand future purchasing power.

Why include fees here?

Even a small annual fee compounds over time. Modeling fee drag keeps long-range projections closer to reality.

What should I open next?

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

What the current scenario means

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

Do not let the return slider do all the work

  • - Using a return assumption that is higher than the portfolio can reasonably support.
  • - Ignoring fees, inflation, or taxes when comparing account types.
  • - Treating a one-time projection as a guarantee instead of a planning range.
  • - Picking a broker before the contribution amount and account type are clear.

FAQ

Compound interest calculator questions

How should I choose a return assumption?

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.

Should I use this for TFSA compound interest?

You can use it as the growth baseline, then open the TFSA calculator to check contribution room and account-specific constraints before contributing.

Does the projection guarantee my future return?

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.

What is a realistic return assumption for Canadian planning?

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.

How do fees affect compound growth?

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.

This calculator is most useful when it becomes a decision tool, not just a projection. Use the compounding result to decide where the money should live and which provider fits the plan.

What this result means

$250,949 is the directional result of your current contribution pace, fee drag, and time horizon. The best next move is usually deciding whether that plan belongs in a TFSA, RRSP, or a more general savings workflow.

Use the result, then act

  • -Compare the same contribution plan inside a TFSA or RRSP before you open an account.
  • -Check whether the monthly amount is realistic enough to repeat consistently.
  • -Only compare brokers or investing apps after the account type and fee sensitivity are clear.

Optional next step

Compare platform details after the growth plan is clear

If the contribution plan looks realistic, compare account types, fees, and platform features before choosing where contributions will go.

Why this may fit after the growth plan

  • - You want to compare recurring contribution workflows and fees.
  • - Your plan is long-term investing, not frequent trading.
  • - You have already checked whether the TFSA or RRSP should be the account wrapper.

Provider terms, promotions, eligibility, and fees can change. Verify details with the provider before opening or funding an account.
