Compound Interest Calculator
Compound Interest Calculator
Compound interest is the reason a modest monthly contribution can turn into a serious nest egg — but the numbers are hard to picture in your head.
Adjust your starting amount, monthly contributions, expected return, and timeline to see the curve. Great for explaining to a spouse why you're maxing the TFSA, or for checking whether your savings plan is ambitious enough. Includes a year-by-year breakdown.
