Every day you do the envelope money challenge, you pull out a random envelope. Whatever number is on that single envelope is the amount of cash you put into it. Once your 100 days are up, your cash envelopes will total $5,050 in savings!
The 100-day money challenge is a version of the broader day money challenge. You still number and fill envelopes in the hopes of finding more financial freedom by the end of it, but you can decide how many days you want to do it.
