Answer six questions and compare your tax rate today with your rate in retirement. The tool gives a clear verdict on where your next dollar fits better, shows the after-tax dollars in each account side by side, and names what would flip the answer.

Our read of your numbers
Put it in your RRSP
Your marginal rate today (31.5%) is 8.3 points higher than the rate expected on withdrawal (23.2%). The RRSP deduction saves tax at the higher rate and you repay it at the lower one.
Same pre-tax dollars, after tax in 30 years: RRSP $16,607, TFSA $14,807.
Your two tax rates
Today, on $95,000
31.5%
What an RRSP deduction saves on each dollar
In retirement, on $55,000
23.2%
What each RRSP withdrawal costs in tax
The anchor fact: if these two rates are equal, the RRSP and the TFSA leave exactly the same amount after tax. The account with the better rate wins, and the gap between the rates sets the size of the win. Rates are for Ontario, 2026 brackets, on the next dollar.
$5,000 of pre-tax income, after tax in 30 years
RRSP
$16,607
All $5,000 goes in (the refund covers the tax), grows to $21,610, then is taxed at 23.2% on the way out.
TFSA
$14,807
Tax at 31.5% comes off first, so $3,426 goes in, then grows and comes out tax-free.
The RRSP leaves about $1,800 more after tax, roughly the gap in rates times the amount.
Both use the same 5% yearly return, an illustration you can change, not a forecast. Because the return is the same in both accounts, it changes the dollar amounts but never which account wins. The RRSP side assumes the tax refund is reinvested; spending the refund shrinks the RRSP result.
The six questions
Does your employer match RRSP contributions? No
Is this money for a first home within ~15 years? No
Might you need this money before retirement? No
Is your income today in your peak-earning years? Yes (from your numbers) settled it
Is your income likely to be higher in retirement than today? No (from your numbers)
Will your retirement income exceed ~$95,000? No (from your numbers)
Worked top to bottom; the first that applies ends the quiz. A match is captured first, and a first home points to the FHSA, whatever the rest says.
What would flip this
If your retirement income rose to about $59,000, the rates would tie, and the TFSA would win on flexibility.
Retirement income above $95,323 adds the 15% OAS recovery tax to every RRSP or RRIF dollar withdrawn, which often flips an RRSP answer to the TFSA.
Needing the money before retirement flips the answer to the TFSA.
An employer match puts the matched dollars in the RRSP first, whatever the rates say.

How the math works
It compares two tax rates. An RRSP deduction saves tax at your marginal rate today; the withdrawal is taxed at your marginal rate in retirement. A TFSA is the reverse: tax now, nothing later. Whichever rate is lower is the one you would rather pay.
Marginal rates come from the 2026 federal and provincial brackets for all 13 provinces and territories, the same engine as our income tax calculator, including Ontario's surtax. Credits other than the basic personal amount are left out.
OAS recovery tax: if your retirement income is above $95,323, 15% of each extra dollar is clawed back from Old Age Security, so the tool adds 15 points to your retirement rate.
Within 3 points it is a tie, and the TFSA comes first for flexibility: tax-free withdrawals at any time, the room back next January 1, and no effect on income-tested benefits.
The rates are on the next dollar. A large RRSP deduction that drops you into a lower bracket saves a little less than shown, and large withdrawals can be taxed a little more.
Withholding is not the final tax. Banks hold back 10% on RRSP withdrawals up to $5,000, 20% from $5,000.01 to $15,000 and 30% above (Quebec differs). Your real tax is settled on your return; this tool models that final tax.
Not modelled: CPP, OAS or GIS amounts (you supply retirement income), spousal planning, non-resident tax, and Quebec-specific rules. The projection is an illustration at the return you pick, not a forecast.
This tool is a planning estimate, not financial advice. It answers which account fits your numbers, not which investments to hold.
