The totals come from simple sums: 1 + 2 + … + 52 = 52 × 53 ÷ 2 = 1,378, and 1 + 2 + … + 100 = 100 × 101 ÷ 2 = 5,050. Change the step and the total scales with it: $2 steps double the 52-week total to $2,756.
The classic version at $1 steps, with the running total at the end of each week.

Frequently asked questions
How does the 52-week savings challenge work?
You save the week number in dollars: $1 in week 1, $2 in week 2, up to $52 in week 52, for $1,378 in total. Double it ($2 × week) for $2,756, or use $5 × week for $6,890. Pick the week 1 amount above and the chart updates.
What is the reverse 52-week challenge?
The same amounts in the opposite order: $52 in week 1 down to $1 in week 52. The total is still $1,378, but the biggest deposits come early while you are most motivated, and the small ones land in the busy weeks at the end of the year. Choose Biggest first.
How does the 100 envelope challenge work?
Number 100 envelopes from 1 to 100. Each day, or whenever you can, pick one at random and put in that many dollars. When all 100 are filled you have $5,050. Use Pick an envelope to draw a random one that is still empty, then tap Fill it.
How long does the 100 envelope challenge take?
One envelope a day takes 100 days and averages $50.50 a day, which is a lot for most budgets. Two envelopes a week takes 50 weeks and averages about $101 a week. Go at the pace your budget allows, or pick the $0.50 step for a $2,525 half version.
What is the 26-week savings challenge?
A version for people paid every two weeks: you save once per paycheck, 26 times a year, and each deposit grows by the same step. At $10 steps that is $10, $20, up to $260, for $3,510. Choose the step above.
How do I make my own savings challenge?
Choose Custom goal, enter how much you want to save, the date you need it by and how often you save. The tracker divides the goal evenly (the last deposit takes any rounding) and gives you a box for every week, two weeks or month.
Where should I keep the money I save?
Government guides such as the CFPB suggest somewhere safe that you will not dip into by accident, like a separate savings account at a bank or credit union. Deposits at FDIC-insured banks are insured up to $250,000; cash at home is not. This page gives general information, not financial advice.
Can I track several savings goals at once?
Yes. Choose Savings tracker to list several funds, like car repairs, holidays or insurance, each with a target, the amount saved and an optional due date. It shows how much to save each month to be ready on time. Our sinking funds guide explains how to size them.
Is my savings data sent anywhere?
No. Your amounts, ticks and funds stay in this browser on this device. There is no sign-up, and the amounts are never sent to our server. Print or save an image to keep a copy.
