Q: Ah!   The magic of compound interest.  Be warned I did this by my adding machine.  What I came up with:
If you contributed the max. amount every year to your TFSA starting Jan.1/09, & made 10% every year, your total contributions of $69,500. magically became $133,029. on Dec. 31/20.
Almost a double! It will be when you put up $6,000. for 2021
