The RRSP vs TFSA calculator compares the after-tax outcome of contributing to a Registered Retirement Savings Plan versus a Tax-Free Savings Account. By factoring in your current tax bracket, expected retirement tax bracket, time horizon, and rate of return, this tool shows you which account will leave you with more money after taxes.
How this RRSP vs TFSA calculator works
Enter your planned annual contribution, time horizon, expected rate of return, current marginal tax rate, and expected retirement marginal tax rate. Toggle whether you will reinvest your RRSP tax refund. The calculator shows the future value, taxes owed, and after-tax amount for both accounts side by side, along with the dollar difference and a clear recommendation.
Key insight: When your current tax rate equals your retirement tax rate and you reinvest the RRSP refund, both accounts produce exactly the same after-tax result. The RRSP only wins when your retirement rate is lower, and the TFSA wins when it is higher.

When the RRSP wins
The RRSP outperforms the TFSA when:
- Your current marginal tax rate is higher than your expected retirement rate — The tax deduction at a high rate combined with withdrawals at a lower rate creates a net tax advantage
- You reinvest the tax refund — Without reinvesting, the RRSP loses most of its advantage
- Your employer offers RRSP matching — Free employer contributions are an immediate 50-100% return
- You need to reduce taxable income — RRSP contributions lower your net income, which can help qualify for income-tested benefits like the Canada Child Benefit
When the TFSA wins
The TFSA outperforms the RRSP when:
- Your retirement tax rate will be the same or higher — Common for lower-income earners or those with pensions
- You value flexibility — TFSA withdrawals are consequence-free
- You want to protect government benefits — OAS clawback starts at $90,997 (2026); TFSA withdrawals don’t count
- You are in a low tax bracket — The RRSP deduction at 15% provides minimal benefit compared to permanent tax-free growth
- You might need the money before retirement — Emergency fund, home down payment, etc.
Optimal strategy: use both
For most Canadians, the ideal approach is to use both accounts strategically:
| Income Level | Recommended Priority |
|---|---|
| Under $57,375 | TFSA first, then RRSP |
| $57,375 – $114,750 | Split 50/50 or RRSP first if employer match |
| $114,750 – $220,000 | RRSP first, then TFSA |
| Over $220,000 | Max both, RRSP priority |
Common mistakes in the RRSP vs TFSA decision
- Not reinvesting the RRSP refund — This is the biggest mistake; without reinvesting, you are effectively contributing less to the RRSP
- Ignoring the impact on government benefits — RRSP withdrawals in retirement can trigger OAS clawback (15% recovery tax above $90,997) and reduce GIS
- Assuming your tax rate will definitely be lower in retirement — Government pensions (CPP, OAS), RRIF minimums, and other income sources may keep you in a similar bracket
- Withdrawing from RRSP for non-retirement purposes — The tax hit plus permanently lost room makes this very costly
- Not considering provincial taxes — Provincial brackets differ from federal; your combined marginal rate is what matters
