Investment Calculator
Our free investment calculator projects the future value of your investments based on an initial lump sum, regular monthly contributions, and an expected annual rate of return. Whether you are investing in stocks, index funds, ETFs, or GICs, this tool helps you visualise how your wealth grows over time.
The investment calculator uses compound growth formulas to show you the power of consistent investing over time. Even modest monthly contributions, when added to a growing investment portfolio, can produce remarkable results over 20 or 30 years. Use this calculator to set investment goals and stay motivated.

When Should You Use an Investment Calculator?
Use the investment calculator when setting long-term financial goals, such as saving for a home down payment, funding college education, or building a retirement nest egg. In particular, it is helpful when deciding how much to invest each month to reach a specific target.
Moreover, the investment calculator is a powerful motivational tool. By showing the compound growth of consistent contributions over time, it reinforces the value of staying invested through market ups and downs. Additionally, use it to compare different return scenarios — conservative (5%), moderate (7%), and aggressive (10%).
Smart Investing Tips for USA and Canada
Building long-term wealth through investing requires patience and consistency. Here are the most important principles:
- Start as early as possible — Time is the most powerful variable in compound growth. Starting at 25 vs 35 can more than double your final portfolio value.
- Invest consistently regardless of market conditions — Dollar-cost averaging reduces the impact of market volatility.
- Minimize fees — High management fees dramatically erode returns over time. Low-cost index funds and ETFs are typically the best choice.
- Use tax-advantaged accounts first — In the USA, prioritize 401(k) and Roth IRA. In Canada, maximize TFSA and RRSP contributions.
- Reinvest dividends — Automatically reinvesting dividends accelerates compound growth significantly.
Frequently Asked Questions About the Investment Calculator
What is a realistic investment return?
Historically, the S&P 500 has returned approximately 10% per year before inflation (about 7% after inflation) over long periods. However, past performance does not guarantee future results, and returns vary significantly year to year.
What is the Rule of 72?
The Rule of 72 is a quick way to estimate how long it takes to double your investment. Divide 72 by your annual return rate. At 8% returns, your money doubles approximately every 9 years (72 ÷ 8 = 9).
