100-Envelope Challenge Supplies: What You Need

The 100-envelope challenge is one of the simplest savings games there is: 100 numbered pockets, one for each number from 1 to 100, and when they’re all full you’ve saved exactly $5,050. But before you start, the internet will happily sell you a drawer’s worth of “essentials” you don’t need.

Short answer: you need 100 numbered pockets, cash, and a tracker. That’s the whole list. Everything else on this page is a nice-to-have that makes finishing easier, not a requirement. Here’s the honest supplies checklist, what each thing does, and what you can safely skip.

The three things you genuinely need

Strip away the marketing and the challenge runs on exactly three items.

1. 100 numbered pockets or envelopes. This is the heart of the system. You need somewhere to physically hold cash in 100 slots numbered 1 through 100. That can be a zippered binder with pre-numbered pockets, a stack of small paper envelopes you number yourself, or even a set of labeled coin bags. The container doesn’t matter to the math; what matters is that each pocket has a number so you know how much goes in it.

2. Cash. The 100-envelope challenge is a cash challenge by design, because handing over physical bills makes saving feel real in a way a bank transfer never does. You draw a number, count out that many dollars, and seal them away. If you’d rather go cashless, you can run the exact same numbers as transfers into a savings account and just cross the number off a tracker, but you lose the tactile part that makes the challenge stick for most people.

3. A tracker. With 100 numbers in play, you will lose track of which ones you’ve done without something to mark. A tracker is just a grid of the numbers 1 to 100 that you cross off as you fill each pocket. Many binders include one printed on the cover or a first page. A free printable or even a hand-drawn grid does the same job.

That’s it. If you have those three things, you can start the challenge tonight.

The upgrade that most people actually want: a binder

Technically optional, but it’s the single item that turns “I’ll start someday” into “I started.” A pre-made 100-envelope binder bundles the numbered pockets, the tracker, and labels into one zippered book, so there’s nothing to set up. You open it and begin on pocket one.

Here’s why the binder earns its $9-to-$16 price for a lot of savers:

• It ships pre-numbered. No sitting down to write 1 through 100 on a hundred separate envelopes, which is exactly the kind of chore that kills a challenge before it starts.
• It keeps everything together. Clear pockets under one cover, so cash can’t scatter across a drawer or fall behind the couch.
• It survives real life. A zippered binder gets tossed in a bag or shoved in a nightstand and holds up. Paper envelopes don’t.
• It looks like something you’ll keep going. Sounds shallow, but a tidy binder you enjoy opening beats a rubber-banded stack you avoid.

Two solid, widely available options at this price point are the Antner A6 budget binder and the Sooez 100-envelope challenge binder. The A6 Antner is compact enough to live in a bag and doubles as a general budget binder after the challenge; the Sooez is purpose-built for the 100-envelope game with a tracker and labels ready to go. Either removes the setup friction that trips up beginners. You can compare both through the buttons at the end of this guide and pick the one that fits how you like to save.

The nice-to-haves (helpful, not essential)

Beyond the core kit, a few small extras make the challenge smoother. None are required, so add them only if they solve a problem you actually have.

Labels or a label maker. If your binder didn’t come pre-numbered, or you’re DIYing, clear number labels beat handwriting for legibility. A sheet of printable labels costs a dollar or two.

A pen that shows up on the tracker. Petty, but a bold pen that crosses numbers off cleanly makes the progress feel more satisfying. Use one you like.

A small pouch for “found” money. Some savers keep a separate zip pouch for spare cash, rebates, or rounding-up change, then use it to fill a pocket or two on tight weeks. It keeps the challenge moving when your regular budget is stretched.

A rubber band or clip. For DIY paper-envelope setups, one band around the whole stack stops the spill-everywhere problem. Cheapest fix on this list.

What you can safely skip

Just as useful as the buy list is the don’t-buy list. These get pushed as essentials and mostly aren’t.

• A fireproof cash box for the whole $5,050. You should never let the balance climb that high at home in the first place (more on that below), so you don’t need a safe sized for it.
• Expensive decorative envelope sets. Pretty is fine, but a $30 designer set saves exactly the same $5,050 as a $9 binder. Spend the difference by, well, not spending it.
• An app subscription to “manage” the challenge. A free tracker grid does everything a paid app does here. This challenge is deliberately low-tech.
• Multiple binders “to be safe.” One is plenty. Buying a backup is the first sign you’re shopping instead of saving.

A quick word on keeping the cash safe

The one supply nobody sells you is a habit: move the money to the bank. A binder is great for the daily draw-and-stuff ritual, but a fat stack of bills sitting at home for months is a theft and fire risk, and homeowner or renter insurance typically reimburses only a few hundred dollars of lost cash. So treat the binder as a staging area, not a vault.

The simple routine: keep filling pockets for motivation, then every week or two, empty the filled ones into a savings account and mark them on your tracker as “banked.” You keep the satisfying physical habit and the visible progress, without ever having thousands of dollars unprotected in a drawer. A high-yield savings account also earns a little interest while the money waits, which loose cash never will.

Put your supplies to work with a plan

Supplies are the easy part. What keeps the challenge alive is fitting the draws to your real budget so you’re not scrambling to find $97 on a bad week. Before you start, it helps to know where the money is coming from each week and where it’s going when you bank it.

That’s exactly what a simple budget does, and our free budget guide can help your 100-envelope cash land somewhere on purpose. You can grab it on our homepage.

Your 60-second shopping list

To recap, here’s the entire thing on one line: 100 numbered pockets (a binder or envelopes), cash, and a tracker are required; a label sheet, a good pen, and a small pouch are optional; and a safe and app subscription are skippable. Total realistic startup cost: $0 to $16.

If you want the zero-setup route, a ready-made A6 binder from Antner or a purpose-built Sooez 100-envelope binder gets you filling pocket one tonight, with the tracker and pockets already done for you. Compare both using the buttons below, then pick the one you’ll actually keep open on the counter.

Once you’ve got your kit, pair it with a budget so every draw has a source and every banked pocket has a home. Start with our free budget guide, and if you want the full walkthrough of how the challenge works, read our guide to the 100 envelope challenge.
