The 100 Envelope Challenge has become a popular savings trend among students and young adults trying to save money on TikTok. 

The idea is simple: label 100 envelopes with the numbers 1 through 100. Each day, choose an envelope and place the corresponding amount of money inside. If you complete all 100 envelopes, you’ll have saved $5,050.

The challenge is catching on because it’s tangible, visual, and flexible. Some people go in order, while others draw randomly to keep things interesting (think of it like a Bingo card). Some start with higher numbers to get them out of the way, and others begin with lower ones to ease into the process.

Whether you choose to do the challenge over 100 days, 100 weeks, or some other interval, the key is consistency.

How It Works

The 100 Envelope Challenge works with simple math and gamification. The goal is to fill all 100 envelopes with corresponding amounts of money.

Envelope 1 = $1

Envelope 2 = $2

Envelope 10 = $10

Envelope100 = $100

Once you stuff them all and add it up, it equals $5,050.

The cool thing is that if you start this in the summer (say July 1), you’ll finish the 100 days on October 9, leaving you money for college in the fall! 

And you don’t need to aim for the full $5,050. For example, you can choose just 50 envelopes and label them $1 to $50, which totals $1,275. Whatever amount feels doable is the right one to start with.

If you tend to spend whatever money is in your student savings account, withdrawing cash and keeping it in a safe place can be helpful. A lockbox, drawer, or envelope binder can make the savings more secure. Just be careful not to dip into it.

Why Students Are Using It

The summer months often offer students a bit more time and flexibility. College students may have jobs or side hustles, internships, or simply more breathing room in their schedules. That makes this the perfect time to start the challenge. It’s an opportunity to set aside extra earnings before the school year begins.

Students are using the money they save for all kinds of reasons: building emergency funds, paying for textbooks, or even covering dorm deposits or travel. Social media has helped popularize the challenge, with creators showing off their binders, envelopes, or custom money boxes. The transparency makes it feel achievable.

There are also psychological benefits. Physically storing money instead of just moving it digitally creates a stronger mental connection to the savings. It feels more real. You see your progress. You resist the temptation to spend it.

And importantly, it’s a challenge. There’s a built-in sense of accomplishment every time you fill another envelope.

Building Good Savings Habits

While it’s fun to join a viral challenge, the bigger lesson is that saving doesn’t have to be complicated or boring. The 100 Envelope Challenge teaches a core financial habit: paying yourself first. Whether you’re setting aside $5 or $95 on a given day, you’re making progress.

The challenge can also help students avoid going into debt for small emergencies. Instead of putting an unexpected expense on a credit card, they now have cash on hand. That shift alone can reduce financial stress.

As with any savings method, the real value comes from doing it consistently and keeping the money untouched until you need it. Whether your goal is a semester’s worth of textbooks, a study abroad deposit, or just peace of mind, this challenge can help get you there.

So if you’re heading into summer with a part-time job or extra income and want to make your money stretch, try the 100 Envelope Challenge. It might start as a TikTok trend, but it can build a real financial cushion that lasts longer than the viral videos.
