For standard arithmetic challenge where Week i deposit = i * Base: Total Principal = Base * [n * (n + 1) / 2], where n = 52. For Base = $1, Total = $1 * (52 * 53 / 2) = $1,378.00.
Starting with just a single dollar bill in week 1 effortlessly accumulates $1,378 in one year.
Select your preferred challenge format (Standard, Reverse, Double, or Flat).
Review the weekly deposit schedule and peak week requirements.
Transfer each week designated deposit into a dedicated savings pocket.
Watch your balance steadily escalate to $1,378 or $2,756 by week 52.
In the Reverse 52-Week Challenge, you deposit $52 in Week 1 (when motivation is highest) and decrease by $1 each week until depositing just $1 in Week 52 (during expensive December holidays).
The standard $1 base challenge yields exactly $1,378.00. The Double Challenge ($2 base) yields $2,756.00.
Because December and November are expensive gift-buying months, the Reverse Challenge makes your end-of-year weekly deposits tiny ($4, $3, $2, $1) instead of demanding $50+.
Yes! Simply combine two consecutive weeks into each bi-weekly deposit (e.g. Paycheck 1 = Week 1 + Week 2 = $3; Paycheck 26 = Week 51 + Week 52 = $103).
Open a separate "Savings Challenge" sub-account in your high-yield savings account so it does not mix with your everyday checking money.
