RRSP vs TFSA Contribution Room Calculator (Canada)
Deciding between an RRSP and a TFSA is one of the biggest money questions Canadian savers face every year. Use the RRSP TFSA contribution room calculator below to find your available room in both accounts, then see which account tends to make more sense for your situation based on your current versus expected future tax bracket.

RRSP vs TFSA: The Core Difference
Both the RRSP (Registered Retirement Savings Plan) and TFSA (Tax-Free Savings Account) are registered accounts that shelter your investment growth from tax, but they work in opposite directions:
| Feature | RRSP | TFSA |
| Contribution deduction | Yes, reduces taxable income now | No deduction |
| Withdrawals | Taxed as income later | Completely tax-free |
| Room based on | 18% of earned income (capped) | Flat dollar limit for everyone |
| Best when | Higher tax bracket now than retirement | Lower/uncertain future bracket, want flexibility |
| Carry-forward | Indefinite | Indefinite |
In short: the RRSP defers tax to a later date (you get the deduction today, pay tax on withdrawal), while the TFSA is funded with after-tax dollars but never taxed again, no matter how much it grows.
How RRSP Contribution Room Is Calculated
Your new RRSP room each year is 18% of your previous year’s earned income, up to an annual dollar maximum set by the CRA (illustrative figure of roughly $32,490 for 2026 — this limit changes every year, so always check your latest Notice of Assessment for your exact number). If you belong to an employer pension plan, a pension adjustment reduces your RRSP room to account for the value of benefits you are already accruing.
Any room you don’t use carries forward indefinitely. This means if you didn’t max out your RRSP in past years, that unused room stacks on top of this year’s new room, sometimes leaving high earners with a very large total contribution limit.
How TFSA Contribution Room Works
Unlike the RRSP, the TFSA limit is a flat dollar amount that applies to every eligible adult regardless of income (illustrative figure of roughly $7,000 for 2026, indexed to inflation and rounded to the nearest $500 each year). You start accumulating room the year you turn 18 (and become a Canadian resident), and like the RRSP, unused room carries forward indefinitely — so if you never opened a TFSA, your cumulative room could be substantial.
Because TFSA withdrawals are added back to your contribution room the following calendar year, it’s also one of the most flexible savings vehicles available to Canadians.
Which Should You Prioritize First?
The conventional wisdom most financial planners use:
- Higher income now, expect lower income in retirement: RRSP first. The deduction is worth more today, and you’ll likely pay less tax on withdrawal later.
- Lower or uncertain income now, or you want flexible access: TFSA first. You’re not sacrificing a valuable deduction, and withdrawals never count as taxable income or affect income-tested benefits.
- Roughly similar tax bracket now and later: Either works well; many planners lean TFSA-first here for its flexibility.
This is general guidance, not personalized financial advice — your specific situation (debt, employer matching, government benefit clawbacks) can change the answer. For example, if you receive income-tested benefits such as the GST/HST credit or the Canada Child Benefit, RRSP contributions can help by lowering your net income, which in turn can increase those benefits. On the other hand, if you’re saving for a shorter-term goal like a home down payment or an emergency fund, the TFSA’s tax-free, penalty-free access makes it the more practical choice regardless of your tax bracket.
It’s also worth remembering that the RRSP and TFSA aren’t your only registered options. The First Home Savings Account (FHSA) offers RRSP-like deductions with TFSA-like tax-free withdrawals for a qualifying first home purchase, and can be a smart addition to your savings order if homeownership is on your radar. Regardless of which accounts you use, the most important habit is contributing consistently and reviewing your available room every year, since limits and your income can both shift.
Over-Contribution Penalties
Both accounts penalize excess contributions at 1% per month on the over-contributed amount for as long as the excess remains in the account. The RRSP does allow a small lifetime cushion (commonly $2,000) before penalties kick in, but the TFSA has no such cushion — any excess is penalized from dollar one. Always double check your available room (using the CRA My Account portal or this calculator) before contributing.
Can You Use Both?
Yes — and most Canadians should, over time. A common strategy is to contribute enough to your RRSP to capture any employer match or reduce your tax bracket meaningfully, then direct additional savings to your TFSA for flexibility, and revisit the split every year as your income and goals change.
Worked Example
Say you earned $70,000 last year with no pension adjustment and have no carry-forward room. Your new RRSP room this year is 18% of $70,000 = $12,600. If you’re 30 years old with $0 already contributed to your TFSA this year and no carry-forward, your TFSA room this year is $7,000. If your tax bracket is higher now than you expect in retirement, the RRSP contribution would generally be prioritized first, with TFSA contributions filling in afterward.
FAQs
Does unused RRSP or TFSA room expire?
No. Both RRSP and TFSA unused contribution room carry forward indefinitely — there is no expiry date.
Can I contribute to both an RRSP and a TFSA in the same year?
Yes. There is no restriction on contributing to both accounts in the same year, as long as you stay within each account’s own available room.
What happens if I over-contribute?
The CRA charges a penalty of 1% per month on the excess amount for as long as it stays in the account. The RRSP typically allows a small lifetime over-contribution cushion (commonly $2,000); the TFSA does not.
Do TFSA withdrawals get added back to my contribution room?
Yes, but only starting the following calendar year, not immediately.
Which account should I max out first?
It depends on your current versus expected future tax bracket. Higher tax bracket now generally favors RRSP first; lower or uncertain future income generally favors TFSA first. This calculator’s Part 3 gives general guidance based on your situation.
