TFSA Calculator — Contribution Room & Growth, 2026
How TFSA room works
Every year you are 18 or older and resident in Canada, you gain the year’s TFSA dollar limit — $7,000 for 2026. Unused room carries forward forever, and money you withdraw is added back to your room on January 1 of the following year. Someone who was already 18 and resident in 2009, when the TFSA launched, and has never contributed has $109,000 of cumulative room in 2026. Growth inside the account and withdrawals are completely tax-free, and withdrawals do not affect income-tested benefits like OAS or GIS.
Worked example
Turned 18 in 2015? Your cumulative room by 2026 is the sum of the annual limits from 2015 to 2026 — $78,000. If you have contributed $20,000 lifetime and never withdrawn, your available room is about $58,000. A $7,000 contribution invested at 5% for 20 years grows to about $18,572 — and every cent can come out tax-free.
Frequently asked questions
What happens if I over-contribute?
The excess is taxed at 1% per month until it is withdrawn. This is the most common TFSA mistake — usually caused by re-contributing a withdrawal in the same calendar year. See TFSA Contribution Room: Common Mistakes.
Can I have more than one TFSA?
Yes, but your room is shared across all of them. The limit applies to you, not to each account.
Does TFSA room depend on income?
No. Unlike the RRSP, TFSA room is the same for everyone in a given year, regardless of earnings.
