Understanding Compound Interest

Compound interest is the interest calculated on the initial principal and the accumulated interest from previous periods. It's often called 'interest on interest' and can significantly boost your investment returns over time.

Key Benefits:

Your money grows exponentially over time
The longer you invest, the more powerful the effect
Regular contributions can dramatically increase your final balance
It works best with long-term investments like ETFs and index funds

Canadian Context:

For Canadian investors, compound interest is particularly powerful when combined with tax-advantaged accounts like TFSAs and RRSPs, where your investments can grow tax-free or tax-deferred.
