How Much Is Enough in a TFSA? Setting a Goal for Your Tax-Free Account

Every dollar earned in a TFSA is tax-free and withdrawals never count as income, but that does not say how large a TFSA balance needs to be. This page looks at what different balances generate in retirement, age-based targets, and the cost of leaving the account in cash. The rest of the TFSA guides are on the TFSA hub.

This page fits the benchmark branch best when read with how much you need to retire in Canada, TFSA vs RRSP for beginners, and am I saving enough for retirement in Canada. If you want to turn the target into a monthly contribution plan, pair it with how much you should invest per month in Canada, the investment calculator, and how to build wealth in Canada.

What a TFSA does in retirement

Income earned in a TFSA and TFSA withdrawals don't reduce federal benefits such as OAS, GIS and EI, or credits such as the Canada child benefit, the Canada workers benefit and the Canada Groceries and Essentials Benefit (formerly the GST/HST credit). TFSA withdrawals are not income, so they do not count toward the OAS recovery tax (above $93,454 of 2025 net income), GIS eligibility or provincial income-tested programs, while RRIF withdrawals, CPP, OAS, pension and rental income all do. That makes a TFSA balance worth more to a retiree than the same balance in a RRIF. The full list of benefits involved is in the TFSA withdrawal rules, and how this shapes the choice between accounts while working is in TFSA or RRSP first.

TFSA targets by life stage

There is no official TFSA target by age, and a target built from averages says little about any one household. Two reference points are more useful than a rule of thumb: the maximum room available (someone eligible every year since 2009 has $109,000 of cumulative room in 2026), and what holders actually have. The CRA’s TFSA statistics for the 2024 contribution year show these average balances (fair market value) by age:

Averages mix people who have barely used the account with people who have filled it, so they are a description, not a goal. The TFSA growth calculator projects a balance from your own contributions, time horizon and return.

What different TFSA balances generate at retirement

Using a 4% withdrawal rate (a commonly used sustainable withdrawal guideline):

Combined with CPP (~$10,300/year at the average amount for new beneficiaries in July 2026) and OAS (up to $9,150/year for ages 65 to 74 at the October to December 2026 rate), a $500,000 TFSA drawn at 4% adds $20,000 a year of tax-free income that does not count toward net income. Whether that is enough depends on spending; how much you need to retire works through the full budget.

The TFSA-only retirement scenario

Is it theoretically possible to fund retirement primarily through a TFSA?

A 25-year-old who:

• Contributes $7,000/year (the full current room amount)
• Increases contributions with new annual room
• Invests in a diversified equity portfolio averaging 7%/year

Contributing at the start of each year for 40 years, this grows to about $1.5 million by age 65 if the contribution stays at $7,000, or about $1.9 million if the annual limit rises 2% a year with indexation. At a 4% withdrawal rate, that is roughly $60,000 to $76,000 a year, tax-free and benefit-neutral, before CPP and OAS.

Reality check: Many Canadians cannot contribute the full TFSA limit every year throughout their careers. Competing financial demands (mortgage, children, debt) interrupt the contribution schedule, and a 7% average return is an assumption, not a guarantee.

The cost of keeping your TFSA as a savings account

An illustration of the gap:

A TFSA earning 3.5% in a HISA held for 30 years on a $100,000 balance grows to approximately $281,000. The same $100,000 invested in a diversified equity index averaging 7%/year grows to approximately $761,000.

The $481,000 difference is the cost of not investing your TFSA.

This does not mean savings accounts have no place in a TFSA: cash needed in the next few years is commonly held in a HISA. The gap above comes from the difference in return over a long period, which is why money that will not be touched for 10+ years is usually held in growth assets rather than a savings account, accepting the market risk that comes with them.

What to hold for a growth target

The targets above assume a diversified, mostly equity portfolio. Short-term money belongs in savings or GICs, but money that will not be touched for ten years or more is what the growth figures depend on. What a TFSA can hold is covered in the complete TFSA guide, current savings and GIC options in best TFSA accounts in Canada, and the TFSA growth calculator projects a balance from your own contributions and return. US dividend payers lose 15% of each dividend to US tax inside a TFSA; see US dividend withholding tax in a TFSA.
