How to use the 52-week challenge calculator
- Pick a version — classic $1, $2, $5 or a flat amount every week — or type your own week-1 deposit and weekly increase.
- Set your start date. The chart lists the date of every deposit.
- Tick "Reverse" if you'd rather start with the biggest deposits.
- Or enter a total you want to save and press "Use this" to get the starting amount that reaches it.
The chart highlights the current week, shows what you should have saved so far, and keeps a running total for all 52 weeks.
Save, print or share your 52-week chart
You don't have to start over next time. Under the calculator you can:
- Save the calculation in your browser with a name, then reopen it from "Saved calculations" whenever you like.
- Copy a link that reopens this exact calculation with all your numbers — on your phone, another computer or for someone you're planning with.
- Print a clean one-page report, or download it as a PDF. It shows a printable 52-week chart with dates, running totals and a tick box for every week, plus a QR code at the top: scan it with your phone camera and the calculation opens again with every number filled in.
- Download a CSV to open in Excel, Google Sheets or Numbers.
Nothing is uploaded: saved calculations stay on your device, and the link and QR code carry your inputs inside the address itself.
The maths of the 52-week challenge
Each week's deposit is: week-1 amount + weekly increase × (week − 1)
So the total over 52 weeks is: 52 × week-1 amount + weekly increase × 1,326
For the classic version that's 52 + 1,326 = $1,378. Because the total is simply 1,378 times your step, you can work backwards from any goal: goal ÷ 1,378 = the amount to start with and add each week.
| Version | Week 1 | Week 52 | Total saved |
|---|---|---|---|
| Classic | $1 | $52 | $1,378 |
| $2 | $2 | $104 | $2,756 |
| $5 | $5 | $260 | $6,890 |
| Flat $25 | $25 | $25 | $1,300 |
Classic, reverse or flat?
- Classic is easy to start but ends with $50+ weeks in December — just when gifts and travel cost the most.
- Reverse front-loads the hard weeks while New Year motivation is high, and the last weeks of the year are almost free.
- Flat saves the same amount every week. It's the most predictable and the easiest to automate.
Our full 52-week savings challenge guide compares the versions and has ideas for staying on track.
Make the challenge stick
- Automate a weekly transfer for the amount of each week, or move a round number and catch up monthly.
- Pair it with a goal. Use the savings goal calculator to give the money a purpose — an emergency fund, a trip, a down payment.
- Find the money. Canceling one unused subscription often covers the early weeks; the subscription cost calculator shows what yours add up to.
- Let it grow. Kept in a savings account and continued for a few years, the money compounds — see the compound interest calculator.
