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

Tax-saving sequence
Estimated RRSP tax saving = bracket-only federal/provincial tax before the deduction minus bracket-only tax after the deduction. Quebec applies the 16.5% federal abatement to the modeled federal component.
After-tax comparison
TFSA finish = contribution stream × growth factor. RRSP finish = RRSP value after the entered withdrawal-tax rate + future value of the selected share of the estimated tax saving that remains invested.

Use realistic numbers. The result is only as strong as the tax-rate and refund assumptions.
Income and tax assumptions
Contribution and growth
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.
Your TFSA vs RRSP decision
Tax Shelter Split Engine™ decision view
At $85,000 of Ontario income, RRSP leads only because the tax saving stays invested.
Inputs: Ontario; $6,000 next contribution; 5.5% annual return; 20 years; 25% future RRSP withdrawal tax; full estimated tax saving invested; room available in both accounts.
Main caution: if the tax saving is spent instead, the RRSP finish falls to about $13,130 and TFSA leads. Example only — enter your numbers for a personal planning estimate.

Compare the five tax-shelter paths
Same contribution, different behavior. The cards below show why the “best account” can change when refund discipline, flexibility, or future tax rate changes.
TFSA path
No tax refund today, but no withdrawal tax in the estimate.
Flexibility is the main strength when access may matter.
RRSP path with full refund invested
Refund is invested beside the RRSP path.
Strongest when current tax rate is higher than future withdrawal tax.
RRSP path with refund spent
The deduction creates cash today, but it does not compound.
This is where many RRSP comparisons become overstated.
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.
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.

Set up a fair TFSA vs RRSP test
Start with the money you are deciding on
Enter the contribution you are actually considering now. The useful question is not “which account is always better?” It is whether this next contribution should go into TFSA or RRSP under today’s income, refund behavior, and expected withdrawal tax later.
Estimate the RRSP refund first if needed
If the RRSP side depends on the size of the tax refund, check the dedicated RRSP Tax Refund Calculator Canada before relying on the comparison. This page compares accounts; the RRSP page estimates the deduction and refund impact in more detail.
Check income pressure before locking money
If the contribution changes your real cash flow, compare it against the Salary After Tax Calculator Canada. If cash reserves are thin, use the Emergency Fund Planner Canada before treating RRSP as the automatic winner.
Use growth calculators after the account choice
Once the account decision is clear, project the tax-free path with the TFSA Growth Estimator Canada or compare a broader compounding path with the Investment Growth Calculator 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.
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, part-time work, or registered withdrawals 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 realistic withdrawal tax, not just the refund cheque. If the RRSP refund itself is still unclear, estimate it with the RRSP Tax Refund Calculator Canada before deciding whether TFSA or RRSP should receive the next contribution.
Turn the tax gap into an account choice
Use RRSP when the tax-rate gap is real
RRSP is stronger when today’s marginal tax rate is clearly higher than the future withdrawal tax rate. If you need the exact deduction value first, estimate the refund with the RRSP Tax Refund Calculator Canada.
Use TFSA when flexibility has value
TFSA is often cleaner when you may need access before retirement, income may rise later, or the RRSP refund is not strong enough. If cash reserves are weak, check the Emergency Fund Planner Canada before locking more money into RRSP.
Split when the result is close
A close result is not a failure. It can mean part of the money belongs in RRSP for the deduction and part belongs in TFSA for flexibility. After choosing the split, project the TFSA side with the TFSA Growth Estimator Canada.
Check retirement tax assumptions
RRSP only wins cleanly if future withdrawals are taxed at a lower or manageable rate. If retirement income may still be meaningful, add context with the CPP Retirement Pension Estimator Canada before assuming future tax will be low.
When Canadian savers should favour TFSA, RRSP, or both
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.
TFSA vs RRSP assumptions that distort the answer
The refund is not free money. If you spend it, it should not be treated like part of the future investment result.
RRSP refund value is driven by the marginal tax rate on the deducted income, not your average tax rate for the year.
Some retirees still have meaningful taxable income from pensions, CPP, OAS, rentals, work, or registered withdrawals.
TFSA and RRSP room limits matter. A good comparison does not override CRA contribution-room rules.
How the 2026 tax-saving estimate feeds the TFSA vs RRSP comparison
The calculator uses the 2026 federal and provincial/territorial statutory brackets to estimate the tax reduction created by the tested RRSP deduction. It calculates bracket-only tax before the contribution and again after subtracting the contribution, so a deduction that crosses a bracket is not treated as one flat marginal rate. It then estimates the RRSP tax saving as:
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. If the final value looks strong but you want to see the real purchasing-power result, test the same return assumption with the Investment Return vs Inflation Calculator Canada.
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: with $85,000 of Ontario taxable income, the 2026 bracket-only model estimates about $1,779 of tax saving from a $6,000 RRSP deduction. If that tax saving stays invested for 20 years at the same entered net return, it materially changes the RRSP finish. If it is spent, the RRSP path relies much more heavily on a lower future withdrawal tax rate to beat TFSA.

Questions to check before acting on the TFSA vs RRSP result
Neither account is always better. RRSP is usually stronger when your current marginal tax rate is higher than your future withdrawal tax rate and you invest the refund. TFSA is often safer when tax rates are close, your future tax rate may be higher, or you need flexible access to the money.
The RRSP deduction creates a refund or reduces tax owing. If that cash is invested, it can compound beside the RRSP and improve the after-tax result. If it is spent, the RRSP comparison can look much weaker than people expect.
A deduction can cross one or more federal or provincial tax brackets. Instead of multiplying the whole contribution by one marginal rate, this model estimates bracket-only tax before and after the deduction. The resulting effective tax-saving rate can therefore be lower than the top rate that applied to your last dollar of income.
TFSA withdrawals generally restore contribution room in a later year, not immediately in the same year. Timing matters because recontributing too soon can create an overcontribution problem.
Yes, RRSP or RRIF withdrawals are taxable income and may affect income-tested benefits, depending on the benefit and your total income. This is one reason future withdrawal tax rate should not be guessed too low.
A close result often supports a split contribution. Put some money into RRSP if the deduction is useful, and keep some in TFSA for flexibility and future tax-rate protection.
