Each name links to its tracker, where you can pick your own first amount and print a chart. The totals are the classic versions. Double the first deposit and every total doubles.
Size a challenge to your goal
The first deposit is rounded up to the cent, so you'll end up a little over your goal, never under it. Type that first amount into the 52 week or 100 envelope tracker and it builds the full chart for you.
Which one fits you?
52 week challenge: steady and gentle
Week 1 saves 1, week 52 saves 52, and the year ends at 1,378. That's 26.50 a week on average, but the first months barely feel like saving. Pick big first if you'd rather not face the largest deposits in December.
26 paydays: for a paycheck every two weeks
One deposit per payday, starting at 10 and rising by 10 each time to 260. It reaches 3,510, about 67.50 a week. It suits people paid every second week, because the deposits line up with the money coming in.
100 envelopes: the biggest total, at your pace
Envelopes 1 to 100 add up to 5,050. There's no calendar: you draw an envelope whenever you can. At two a week it takes 50 weeks and averages 101 a week, so it's the most demanding of the four, and the most flexible.
Penny challenge: the smallest start
One penny on day one, one more each day, up to 3.65 on day 365. It comes to 667.95, about 12.85 a week, and the early weeks cost almost nothing. It needs a daily habit, or a weekly catch up.
No spend days: save by not spending
A different kind of challenge, with no deposits at all. You tick each day you spend nothing outside your essentials, and move what you kept into savings. The no spend challenge calendar tracks the days and your streak, and prints a month for the fridge.
Why the totals look like that
All four use the same rule: deposit number n is n times the first. So the total is the first deposit times 1 + 2 + 3 and so on up to the last number, and that sum is the last number times the next one, halved. For 52 weeks that's 52 times 53 over 2, which is 1,378. For 100 envelopes, 100 times 101 over 2 is 5,050.
That's also why the goal finder above is just a division. Want twice the total? Double the first deposit.
Whatever you pick
- Tie the deposit to something you already do each week, like payday or Sunday evening.
- Keep the money apart from your spending money, in a jar or a separate savings account.
- Missed one? Catch up next time, or skip it and carry on. A smaller total beats quitting.
None of this is financial advice. It's arithmetic and a habit, and the habit is the hard part.
Questions
Which savings challenge saves the most?
Of the classic versions, the 100 envelope challenge, at 5,050. But any of them can save more if you raise the first deposit. The goal finder above shows what each needs.
Which is easiest to keep up?
The penny challenge and the 52 week challenge both start very small, so the habit forms before the deposits get big. The 26 payday version suits people paid every two weeks.
Can I run two at once?
Yes, as long as the money's there. My app keeps several challenges side by side, each with its own jar.
Do these work in pounds or euros?
Yes. The totals are the same numbers in any currency. The trackers let you pick dollars, pounds, euros and more.
