If you saved a penny a day for a year you would have $3.65. If you did the penny challenge instead, you would have $164.71 after 6 months and $667.95 after 1 full year.
If you get paid weekly this is the challenge for you. Instead of worrying about daily amounts, I’ve listed everything in weekly totals. This makes it easier for you to pick a day and save the total amount for the week all at once.
