Understanding Your Retirement Investment Options
Choosing the right retirement investment vehicles is one of the most consequential financial decisions you can make. The difference between investing in a tax-advantaged account versus a taxable account can amount to hundreds of thousands of dollars over a career. Each account type has unique tax advantages, contribution limits, withdrawal rules, and investment options that make it more or less suitable depending on your specific financial situation, income level, and retirement timeline.
This calculator helps you compare the after-tax value of different retirement investment options side by side, so you can make an informed decision about where to allocate your retirement savings. The key insight is that it is not just about the gross return but the after-tax return that determines your actual retirement wealth.
Tax-advantaged accounts like 401(k)s and IRAs can boost your retirement savings by 20-40% compared to taxable brokerage accounts, depending on your tax bracket and investment horizon. The longer your time horizon, the greater the advantage.

How to Choose the Right Account
The choice between traditional (pre-tax) and Roth (after-tax) accounts primarily depends on your current tax rate versus your expected tax rate in retirement. If you expect to be in a lower tax bracket in retirement, traditional accounts provide more value because you defer taxes from a higher rate to a lower rate. If you expect your tax rate to increase, Roth accounts are typically better because you pay taxes now at the lower rate and enjoy tax-free withdrawals later.
Investment Options Within Retirement Accounts
- Index funds: Low-cost diversified exposure to the stock or bond market, typically 0.03-0.20% expense ratio
- Target-date funds: Automatically adjust asset allocation as you approach retirement, a set-it-and-forget-it option
- Individual stocks: Higher risk but potential for higher returns; not recommended as the sole strategy for retirement
- Bond funds: Lower volatility than stocks, suitable for investors closer to retirement who need income and stability
- REITs: Real estate investment trusts provide exposure to real estate with dividend income, often yielding 3-6%
- Stable value funds: Available in many 401(k) plans, offer capital preservation with modest returns above money market rates

Canadian Retirement Investment Options
Canadian investors have their own set of tax-advantaged retirement accounts. The RRSP (Registered Retirement Savings Plan) works similarly to a US Traditional IRA, with tax-deductible contributions and deferred taxation. The TFSA (Tax-Free Savings Account) is comparable to a Roth IRA, with after-tax contributions and completely tax-free growth and withdrawals. The RRSP contribution limit for 2024 is 18% of earned income up to $31,560, while the TFSA limit is $7,000 per year. Canadian investors should also factor in Canada Pension Plan (CPP) and Old Age Security (OAS) benefits when planning for retirement.
