How it works
- Pick how often you will fill an envelope — most people do one a day (about 14 weeks) or two a week.
- Tap "Draw an envelope" for a random unfilled number, or tap any envelope yourself.
- Move that amount to savings (a real envelope or a separate savings account), then mark it filled.
- Short on cash this week? Draw a small one. That flexibility is the whole point of shuffling.
Tips that keep it going
- $5,050 in 100 days is roughly $50 a day on average, which is a lot for most budgets. Halving it (50¢ per number, $2,525 total) keeps the game and loses the stress.
- Keep large envelopes for paydays and small ones for tight weeks.
- If you use a bank account instead of cash, note the envelope number in the transfer memo so your tracker and bank agree.
Pros and cons
Pros
- Random draws make tight weeks manageable: pick a small number.

Questions people ask
How much do you save with the 100 envelope challenge?
Numbers 1 through 100 add up to 5,050, so filling every envelope saves $5,050. At 50 cents per number it is $2,525; at $2 per number it is $10,100.
How long does the 100 envelope challenge take?
It is usually done one envelope a day, about 100 days. Doing two envelopes a week stretches it to about a year, which cuts the average weekly amount to roughly $97.
Do I have to use cash?
No. Plenty of people fill "virtual" envelopes by transferring the amount to a high-yield savings account, which also earns interest and is harder to dip into.
Can I save $5,000 in 3 months with 100 envelopes?
Only with a high income: 13 weeks means about eight envelopes and roughly $390 a week on average. The pace planner on this page shows the weekly amount for any finish date you pick.
How many envelopes a week should I do?
Divide 100 by the number of weeks you want it to take. Finishing in a year means about two envelopes a week (around $97 a week); finishing in six months means about four a week (around $194).
Is the 100 envelope challenge safe with cash at home?
Cash at home is not insured against theft, fire or loss. Many people use envelopes only for tracking and move the money into an FDIC- or NCUA-insured savings account each week.
