How the 100 Envelope Challenge Works

Imagine saving $5,000 in only 100 days. It’s called a challenge, but the process is quite simple. You get 100 empty envelopes and write the numbers 1 to 100 on them. Then each day, for 100 days, randomly choose an envelope. Whatever number is on the front of the envelope you select for a given day, you put that amount of money into the envelope.

Using Digital Envelopes

Instead of using 100 physical envelopes, a more practical way of doing the 100-day money challenge is to do it digitally. Here’s how: 

How To Save $5,000 in 100 Days

  1. Get 100 empty envelopes. Use an envelope size that cash bills can easily fit into. Coins are fine to use, but they can be a hassle to keep in the envelopes.
  2. Number each envelope from 1 to 100. Keep them in order for now; you will shuffle the order in the fourth step.
  3. Store your envelopes in a container. Choose a container that works easiest for you. It can be a box, a basket or something else. An empty shoebox is a good option. 
  4. Shuffle the envelopes in random order. The idea is to be surprised by the amount you save each day.
  5. Pick an envelope at random each day. Without looking, take an envelope from the box. Try not to cheat and select an envelope with the amount you think that you can safely save that day.
  6. Insert the day’s money amount in the envelope. Whatever number is on the envelope you pick, place that cash value inside. For example, if you pull the envelope with the number 50 on it, put $50 inside that envelope and seal it.
  7. Put the filled envelope aside. You can place the filled and sealed envelopes in the back of the box or in a separate secure location until the 100-day money challenge is complete. If you use the same box, try putting a divider between the empty and filled envelopes or placing the filled envelopes upside down.
  8. Track your savings progress. To motivate yourself not to quit the challenge, consider keeping a ledger of your savings either on paper or by using a spreadsheet or a free mobile app.
  9. Finish the challenge. When your box of envelopes is either empty or replaced with cash-filled envelopes, you will have saved $5,050 and completed the 100 envelope challenge.
