Retirement planning is about ensuring your money outlasts you. The power of compound growth means that starting early, even with small amounts, can make an enormous difference by retirement.
The 4% rule is a widely-used guideline suggesting you can safely withdraw 4% of your retirement portfolio per year without depleting your savings over a 30-year retirement. To retire with $50,000 per year in income, you would need approximately $1,250,000 saved.
The earlier you start, the more time your money has to grow. A 25-year-old investing $300/month at 7% returns will have significantly more at 65 than a 35-year-old investing $600/month — the extra decade of compounding is that powerful.
If you're 50 or older, the IRS allows higher annual contribution limits to 401(k) and IRA accounts. For 2024, the 401(k) limit is $23,000 ($30,500 with catch-up). The IRA limit is $7,000 ($8,000 with catch-up). Take full advantage of these limits.
Social Security benefits are not included in this projection. The average monthly Social Security benefit as of 2024 is approximately $1,900. You can get your personal estimate at ssa.gov. Social Security should be considered supplemental income, not the foundation of your retirement plan.
Consider two people, both targeting retirement at 65. Alex starts at 30 with $20,000 in savings and contributes $500/month at a 7% annual return. By 65, Alex accumulates approximately $1.37 million. Jordan starts at 40 with the same $20,000 but contributes $1,000/month — double the amount — at the same 7% return. By 65, Jordan has approximately $813,000. Alex ends up with 68% more despite contributing half as much per month. The 10 extra years of compounding is worth more than the doubled contribution.
Canada's two primary tax-advantaged retirement vehicles work differently. An RRSP (Registered Retirement Savings Plan) gives you a tax deduction on contributions — contributing $10,000 to an RRSP reduces your taxable income by $10,000. Growth is tax-sheltered, but withdrawals in retirement are taxed as income (ideally at a lower rate than during working years). A TFSA (Tax-Free Savings Account) uses after-tax dollars, but all investment growth and withdrawals are completely tax-free. Most financial advisors recommend maxing RRSP first if you're in a high tax bracket, and TFSA first if you're in a lower bracket.
Canada Pension Plan (CPP) provides retirement income based on your contributions during your working years. The maximum CPP benefit at age 65 in 2025 is approximately $1,364/month, but the average is closer to $800/month. Old Age Security (OAS) adds up to $700/month for those 65 and older. Combined, CPP + OAS typically covers only 30–40% of pre-retirement income for average earners. Your personal savings need to cover the rest.
The order in which you experience investment returns matters enormously in retirement. If the market drops 30% in your first two years of retirement while you're making withdrawals, you sell more shares at the bottom to fund living expenses — permanently reducing your portfolio. This "sequence of returns risk" is why maintaining 2–3 years of living expenses in cash or short-term bonds at the start of retirement is a key defensive strategy.
This free retirement savings calculator uses compound interest growth to project exactly how much money you will have when you retire. Enter your current age, retirement age, current savings, monthly contributions, and expected rate of return to see your projected 401k balance and whether you are on track. It functions as both a finance calculator and a compound interest retirement calculator in one tool.
The calculator applies the power of compound interest to model your investment growth year by year. Using it as an interest rate calculator, you can test different return scenarios to stress-test your retirement plan. See how increasing contributions or retiring a few years later dramatically changes your final balance — real insights for real planning.
A common starting point is 25× your expected annual retirement expenses (the 4% rule). If you plan to spend $50,000/year, you need roughly $1,250,000 saved. Your actual number depends on your lifestyle, government benefits (CPP, OAS, Social Security), health costs, and how long you expect to live.
The 4% rule states that if you withdraw 4% of your portfolio in year one and adjust for inflation each subsequent year, your savings have historically lasted 30+ years. It is based on decades of market data. For retirements longer than 30 years, a more conservative 3–3.5% withdrawal rate is often recommended.
As early as possible — ideally in your 20s. Compound growth means money invested at 25 has 40 years to grow before retirement at 65. Starting 10 years later (at 35) and doubling your monthly contributions still results in a significantly smaller final balance. Time in the market is more valuable than the amount contributed.
An RRSP gives you a tax deduction now (contributions reduce taxable income) but withdrawals in retirement are taxed as income. A TFSA uses after-tax dollars but all growth and withdrawals are completely tax-free. Generally: use RRSP first if you're in a high tax bracket today; TFSA first if you're in a lower bracket or expect high retirement income.
Inflation erodes purchasing power over time. At 2.5% annual inflation, $50,000 today buys what only $30,500 buys in 20 years. Your investments must earn returns above the inflation rate to maintain real wealth. This is why holding only cash or GICs in a retirement portfolio is risky — you need growth assets like equities to outpace inflation over the long term.
If your employer matches RRSP or 401(k) contributions, always contribute enough to capture the full match first — it is an instant 50–100% return. After that, pay off high-interest debt (above ~6–7% rate) before investing more. Low-interest debt (below 4%) can be carried while you invest, since expected market returns typically exceed the debt cost.
Yes. The FIRE (Financial Independence, Retire Early) movement shows this is achievable by saving 50–70% of income and keeping expenses low. The key challenge is that early retirement requires a larger portfolio (to sustain 40–50 years of withdrawals) and a lower withdrawal rate (closer to 3%) to reduce the risk of running out of money.
Sequence of returns risk is the danger of experiencing large market losses early in retirement while you are making withdrawals. Selling assets at low prices to fund living expenses permanently reduces your portfolio size and future growth potential. Holding 2–3 years of expenses in cash or bonds helps you avoid forced selling during market downturns.
