How interest is calculated can greatly affect your savings. The more often interest is compounded, or added to your account, the more you earn. This calculator demonstrates how compounding can affect your savings, and how interest on your interest really adds up!
The amount of your initial investment.
The annual interest rate for your investment. The actual rate of return is largely dependent on the type of investments you select. For example, the total return including dividends of the S&P/TSX Composite Index for the 10 year period ending December 31, 2025 was 12.5% (source www.spglobal.com). Savings accounts at a bank or credit union may pay as little as 2% or less. It is important to remember that future rates of return can't be predicted with certainty and that investments that pay higher rates of return are subject to higher risk and volatility. La tasa real de rendimiento de las inversiones puede variar significativamente con el tiempo, en especial en las inversiones a largo plazo. También puede implicar la posible pérdida de capital invertido.
