A savings challenge is a page full of amounts. Each time you put money aside, you color in the matching amount, and after a few weeks the colored part shows how far you've come. This bundle has 24 of them, so you can pick one that fits your budget instead of forcing yourself through a challenge that's too big.
The well-known ones are here: the 100 Envelope Challenge, the 52 Week Challenge with running totals and its reverse version that starts with the big weeks. There are also round goals from 100 to 10,000 and themed funds for an emergency, a home, a vacation, a car, gifts, a baby or a pet.
None of the pages has a currency sign, so the numbers mean dollars, euros, pounds or anything else. If none of the goals fits, two blank challenges let you write in your own amounts, and a percent tracker works for any target.
