TFSA vs RRSP Comparison Calculator Canada

Decide where your next contribution should go by comparing after-tax future value, RRSP refund discipline, future withdrawal tax, contribution room pressure, and flexibility risk.

Decision preview
RRSP can win only if the refund is handled well.

The same contribution can produce a very different result depending on whether the RRSP refund is invested, partly invested, or spent.

Inputs

Use realistic numbers. The result is only as strong as the tax-rate and refund assumptions.

Income and tax assumptions

Used to estimate a simplified current marginal tax rate.
$
Use taxable income before the TFSA/RRSP contribution being tested.
%
Estimate the tax rate on future RRSP withdrawals. This can be very different from today.
This is the swing factor. RRSP results change sharply if the refund is not invested.

Contribution room and access needs

💡

RRSP looks stronger when today’s tax rate is meaningfully higher than the future withdrawal rate.

⚠️

Spending the RRSP refund can erase much of the advantage people expect from the deduction.

🧭

TFSA often wins on flexibility even when the pure math is close.

TFSA path $0

TFSA path

No tax refund today, but no withdrawal tax in the estimate.

Flexibility is the main strength when access may matter.

Wins when future tax or access risk is high.
RRSP full refund $0

RRSP path with full refund invested

Refund is invested beside the RRSP path.

Strongest when current tax rate is higher than future withdrawal tax.

Wins when refund discipline is strong.
RRSP refund spent $0

RRSP path with refund spent

The deduction creates cash today, but it does not compound.

This is where many RRSP comparisons become overstated.

Rarely wins unless tax-rate gap is large.
Split path $0

Split contribution path

A blended strategy can capture some deduction value while keeping TFSA flexibility.

Useful when the math is close or the future tax rate is uncertain.

Often smarter when the winner is not decisive.
Stress case $0

Higher future tax rate stress case

Tests what happens if retirement withdrawal tax is higher than expected.

This catches cases where RRSP only wins under an optimistic tax assumption.

TFSA becomes safer when future tax rises above the break-even point.

How to use this TFSA vs RRSP comparison

Start with the next-dollar decision

Enter the contribution you are actually considering now. For many Canadians, the useful question is not “which account is always better?” It is whether the next $1,000, $6,000, or $20,000 should go into TFSA or RRSP under today’s income and your expected withdrawal tax later.

Do not ignore the refund behavior

A RRSP contribution can look stronger because it creates a refund today. But if that refund is spent, the comparison changes. Use the refund behavior selector honestly — it is often the difference between a tax strategy and a temporary cash-flow boost.

Check room before acting

If the contribution is above your TFSA or RRSP room, the calculator will warn you. Confirm room in CRA My Account before contributing. A mathematically “better” account is not useful if it creates an overcontribution problem.

Use related calculators for the next layer

After this comparison, test the dedicated refund estimate with the RRSP Tax Refund Calculator Canada, then compare the long-term contribution path with the TFSA Growth Estimator Canada.

What your TFSA vs RRSP result actually means

The result is not a permanent label on either account. It is a test of one contribution under your current assumptions. RRSP tends to look better when your current marginal tax rate is high, your future withdrawal tax rate is lower, and you invest the refund. TFSA tends to look safer when tax rates are close, your future tax rate may be higher, you need access, or the RRSP refund is likely to be spent.

RRSP math win Usually means the deduction and refund are doing real work.
TFSA safety win Usually means future tax or access risk matters more than the deduction.
Too close Often means a split strategy is more realistic than picking one account only.

A common Canadian example: someone earning about $85,000 may get a useful RRSP deduction, but if they expect pension income, CPP, OAS, rental income, or part-time work later, the future tax rate might not be as low as they assume. That does not make RRSP bad — it means the decision should be based on a realistic withdrawal tax rate, not just the refund cheque.

How to make a decision

01

Use RRSP when the tax-rate gap is real

If your estimated current marginal rate is clearly higher than your future withdrawal tax rate, RRSP can create a strong after-tax result — especially when the refund is invested.

02

Use TFSA when flexibility has value

If you may need access before retirement, TFSA usually carries less friction. RRSP withdrawals are taxable and can affect future income-tested benefits.

03

Split when the result is close

A close result is not a failure. It can be a signal to put part of the contribution into RRSP for the deduction and part into TFSA for flexibility.

04

Never let the refund disappear unnoticed

If RRSP only wins when the refund is invested, make that automatic. Move the refund into TFSA, RRSP, or another investment account before it blends into regular spending.

Real Canadian scenarios

Middle-income saver with room in both accounts

A person earning $70,000–$90,000 may see RRSP look attractive because the refund is meaningful. But if the refund is used for a vacation or bills instead of being invested, TFSA may leave a cleaner long-term result with less tax risk.

High-income year with a temporary spike

Someone with overtime, bonus income, severance, or a unusually strong business year may benefit from RRSP because today’s marginal rate is temporarily high. In that case, compare this page with the Salary After Tax Calculator Canada to understand the paycheque and tax impact.

Early saver who may need the money

A younger saver building a home down payment or emergency buffer may prefer TFSA even if RRSP is close. The ability to withdraw without immediate tax can matter more than a slightly higher projected value.

Near-retirement saver with pension income

If you expect pension income, CPP, OAS, or other taxable income later, the future RRSP withdrawal rate may not be low. Use the CPP Retirement Pension Estimator Canada to add context before assuming retirement tax will drop sharply.

Common mistakes

Counting the RRSP refund twice

The refund is not free money. If you spend it, it should not be treated like part of the future investment result.

Using average tax rate instead of marginal tax rate

RRSP refund value is driven by the marginal tax rate on the deducted income, not your average tax rate for the year.

Assuming retirement tax will always be low

Some retirees still have meaningful taxable income from pensions, CPP, OAS, rentals, work, or registered withdrawals.

Ignoring contribution room

TFSA and RRSP room limits matter. A good comparison does not override CRA contribution-room rules.

How the calculation works

The calculator estimates a current marginal tax rate from your province and taxable income using simplified federal and provincial bracket assumptions. It then estimates the RRSP refund as:

RRSP refund = contribution × estimated current marginal tax rate

The TFSA path compounds the contribution for the selected time horizon and assumes the withdrawal is generally tax-free. The RRSP path compounds the contribution inside the RRSP, then applies the expected withdrawal tax rate. If the refund is invested, the calculator also compounds the invested refund amount as a side value.

RRSP after-tax path = RRSP future value × (1 − future withdrawal tax rate) + invested refund future value

The break-even future tax rate estimates where the TFSA and RRSP full-refund-invested paths are roughly equal. If your expected future tax rate is above that break-even point, TFSA becomes more attractive. If it is below that point, RRSP has more room to win — but only if contribution room and refund behavior support the plan.

Planning example: a $6,000 contribution at a 30% current marginal rate creates an estimated $1,800 RRSP refund. If that refund is invested for 20 years, it can materially change the RRSP result. If it is spent, the RRSP path relies much more heavily on a lower future withdrawal tax rate to beat TFSA.

This page provides a planning estimate only. It is not tax advice, financial advice, or a CRA calculation. Actual marginal tax rates can differ because deductions, credits, benefits, pension income, RRSP room, payroll deductions, province rules, income type, contribution limits, and future tax rules can change. Confirm TFSA/RRSP room with CRA My Account and consider professional advice for major contributions.
