How the 100 envelope challenge works
- Number 100 envelopes from 1 to 100.
- Each time you save, pick an envelope (in any order) and put that many dollars in it: envelope 37 gets $37.
- When all 100 are full, you've saved $5,050.
Use the tracker above: tap an envelope when you fill it, or press Draw a random envelope to let chance decide. Press Save to keep your progress in this browser.

Tips to finish
- Mix big and small. Pair envelope 90 with envelope 5 in the same week so no week is too painful.
- Go small first in tight months. Save the big numbers for paydays, tax refunds or bonus weeks.
- Pick a pace you can keep. One a day is intense; two or three a week is realistic for most budgets.
- Bank it. Cash at home can disappear. Move each week's envelopes into a high-yield savings account; see how much interest it adds with the savings calculator.
- Give it a purpose. An emergency fund, a trip, the holidays. The emergency fund calculator is a good place to start.
Is $50 a day realistic?
For many people, no, and that's fine. The challenge works because you choose the order and the pace. At two envelopes a week (about $101 a week on average) you'll finish in about a year. If even that's too much, try the half-dollar version, or the gentler 52-week savings challenge, which starts at $1 and saves $1,378. Our 52-week challenge guide has more ideas.
Where to keep the money
Envelopes are fun, but money earning interest is better. Once a week, move what you've put aside into a separate high-yield savings account. If you won't need it for a while, a CD can lock in a rate; see CD vs high-yield savings. To set a target and date for something specific, use the savings goal calculator.
