100 envelope challenge — your printable tracker, total and signed plan
Short answer. Your savings plan is open below — type your name and goal. 100 envelopes at $1: Envelope n holds $n: $1 to $100, $5,050 in total (Arithmetic: 1 + 2 + … + 100 = 5,050).
- Envelope 50 — halfway: type the date
- Envelope 100 — last one (one a day): type the date
- Week 52 — last deposit (52-week challenge): type the date
Check your own case.
One envelope a day: envelope n falls n − 1 days after the first. In the 52-week challenge, week n falls 7 × (n − 1) days after week 1.

Your plan
Your savings challenge — every date and every amount
A goal, a way to save and the day you start. You get every envelope (or every week), the running total and the chart; the tracker prints on one sheet.
- Number 100 envelopes, or print the tracker and keep it on the fridge. Any envelope order works — the total stays the same.
- Sign your plan. To make it automatic, hand your bank the recurring transfer request in the Word file.
- When you finish, move the cash to a savings account — it is safer than envelopes at home.
Arithmetic only: envelope n holds n × step, step = goal ÷ (1 + 2 + … + 100) rounded up to the dollar ($1 × 100 envelopes = $5,050); 52 weeks — week n × step ($1 × 52 weeks = $1,378); same amount — goal ÷ 52 rounded up. Bank deposits are insured by the FDIC to at least $250,000 at each insured bank (FDIC).

Give me your goal and I will give you every envelope with a date. Tick them off — the chart shows how far you are.
Pick the pace you will really keep. A plan you finish beats a big plan you drop in week three.

Deadlines
The rules, with the source
| What | Deadline | Source |
|---|---|---|
| 100 envelopes at $1 | Envelope n holds $n: $1 to $100, $5,050 in total | Arithmetic: 1 + 2 + … + 100 = 5,050 |
| 100 envelopes at $2 | $2 to $200, $10,100 in total | Same formula |
| Any goal | Step = goal ÷ 5,050, rounded up to the dollar | Same formula |
| 52-week money challenge | $1 × week number: $1 in week 1, $52 in week 52, $1,378 in total | Arithmetic: 1 + 2 + … + 52 = 1,378 |
| Savings account | Deposits are insured by the FDIC to at least $250,000 at each insured bank | FDIC — deposit insurance |
Cash in envelopes at home earns nothing and is not insured. Moving it to a savings account at an FDIC-insured bank — or setting up a recurring transfer — keeps it safe.
Step by step
What to do, in order
1
Pick a goal
$5,050 is the classic. A smaller goal means a smaller step; 50 envelopes works too.
2
Pick day 1
The calculator dates every envelope — one a day, or pick the 52-week mode.
3
Print the tracker
Download the Excel or print the plan below. Number your envelopes 1 to 100.
4
Sign your plan
Writing it down and signing it makes it harder to quit halfway.
5
Make it automatic
Hand your bank the recurring transfer request (page 2 of the Word file).
6
Fill and tick
Any envelope order works. Missed a day? Do two the next — the total stays the same.
