TFSA Contribution Room Calculator Canada

This TFSA contribution room calculator estimates your lifetime room from your birth year, past contributions and withdrawals from earlier years.

What it does

The TFSA contribution room calculator estimates your total lifetime room from your birth year and how much you have already contributed.

Data sources & parameters

The figures below drive this calculator. We keep them aligned with the latest official guidance, and each result recalculates automatically whenever a value changes.

Parameter	Value	Source	Last updated
TFSA annual dollar limits by year	Rate schedule	canada.ca	Effective 2026-01-01The table stopped at 2025, so lifetime room was understated by the 2026 limit. 2026 = $7,000 added from the CRA limits table.
Age from which TFSA contribution room accrues	18	laws-lois.justice.gc.ca	Effective 2026-01-01Income Tax Act s. 146.2(1) requires the holder to be "at least 18 years of age"; the age was a literal in the calculator.

We always strive to use the latest data for every variable so our results and reports are as accurate as possible. Even so, errors are possible — you should not rely on this tool or its report alone, and we accept no liability for any decision made based on it.

The formula

Cumulative room = sum of annual limits since eligibility; available = cumulative - contributed

How it works

Room begins accruing in the later of 2009 and the year you turned 18, then adds each year's annual limit up to the current year. Subtracting your contributions gives the room still available.

Where it is used

Estimating lifetime TFSA room
Checking room before contributing
Avoiding over-contribution penalties

Worked example

Born in 1990 and eligible since 2009, the cumulative room is …, all of it available if nothing has been contributed.

What the TFSA contribution room calculator does

The most important TFSA number, how much you are allowed to put in, is easy to lose track of. From your birth year, your total contributions and any withdrawals from previous years, the calculator estimates your cumulative lifetime room and how much remains available. Over-contributing brings a penalty, so check before you add money.

How contribution room accrues

Each year you are an eligible resident, the annual limit is added to your room. Accrual starts in the later of 2009, the year the TFSA was introduced, and the year you turned 18, and the calculator adds the limit for every year from then to now.

Why the annual limits vary

The annual limit has been raised over time and is indexed to inflation, with occasional larger jumps, such as $10,000 in 2015. The calculator uses the official limit for each year rather than an average.

Worked examples

Someone born in 1990, eligible since 2009, who has never contributed has $109,000 of room for 2026. Someone born in 2005, who turned 18 in 2023, has $27,500.

If the person born in 1990 has contributed $60,000 and withdrew $10,000 in earlier years, $50,000 of room is used and $59,000 is available. The number of eligible years builds cumulative room, contributions use it, and earlier withdrawals give some back.

Available versus cumulative room

Cumulative room is everything you have been granted; available room is what is left after contributions, plus withdrawals from previous years. A withdrawal is added back to your room only on 1 January of the following year, so enter only withdrawals from earlier years. Money taken out this year does not restore room until next year.

Age of majority and where you live

The limits are federal and the same everywhere, but you can open a TFSA only at your province’s age of majority. That is 18 in Alberta, Manitoba, Ontario, Quebec, Saskatchewan and Prince Edward Island, and 19 in British Columbia, New Brunswick, Newfoundland and Labrador, Nova Scotia, Yukon, the Northwest Territories and Nunavut. An 18-year-old in the second group must wait a year to open an account, but room for that year still accrues and carries forward. The calculator counts room from the year you turned 18, as the CRA does.

When to use it

Before contributing, to make sure you have room.
When starting out, to see how much room has built up.
After a withdrawal, to know when the room returns.
When deciding how much to put in a TFSA versus other accounts.

Common mistakes and CRA records

Re-contributing a withdrawal in the same calendar year, which can push you over your limit and trigger the 1% monthly penalty tax, reported on Form RC243.
Relying on the room in CRA My Account as if it were live. It is accurate as of 1 January and can lag behind contributions or withdrawals your institution has not yet reported.
Forgetting residency. Room does not accrue for years as a non-resident, and contributions made while non-resident carry their own tax.

Keep your own running record alongside the official one, and confirm the CRA figure before a large contribution. The estimate assumes residency every year and cannot see this year’s activity.

Frequently asked questions

What does the TFSA contribution room calculator work out?

The total room you have built up in your Tax-Free Savings Account since you became eligible, and how much is still available after the contributions you have made and the withdrawals from earlier years that have been added back.

When does TFSA room start accruing?

In the later of 2009, when the TFSA began, and the year you turned 18. Someone who was already an adult in 2009 has room from that year; someone younger starts from the year they turned 18.

Does unused room carry forward?

Yes. Unused room carries forward indefinitely and adds to future years, which is why someone eligible for many years can have a lot of room without ever contributing.

How accurate is this estimate?

The calculator uses the official limit for each year, so the cumulative figure is exact for someone resident all along. Your real available room can differ if you were a non-resident for some years or made withdrawals this year, which return to your room only the following year. CRA My Account holds the official figure.

What happens if I over-contribute?

Contributions beyond your available room are taxed at 1% a month on the excess while it remains. Check your room before contributing.

Is my data private?

Yes. The calculation runs entirely in your browser. Nothing you enter is uploaded, stored or shared.

Taha Kheirandish reads tax codes the way other people read maps — to find out where a system actually leads, not where it claims to go.

He is an economics student, and his work here is comparative by design. A pension deferral bonus in Quebec, a commuting allowance in Germany, a rent-increase ceiling in the Netherlands: each is a decision a government made about how money should move, and each reads differently once you set it beside eight others. He builds and checks these calculators across nine markets from primary sources — the regulation rather than a summary of it, the ministry’s own circular rather than a news item quoting it.

That is the editorial standard of the site as well as his habit. Every rate, threshold and bracket here carries the document it was read from and the date it takes effect, and gets re-checked when the law moves rather than when someone happens to notice.

He is a researcher, not a licensed adviser, and nothing on this site is personal financial advice. It is arithmetic done carefully with its sources shown — so that you can check it, and take it to someone who is.
