What's inside
- Challenges: 52-week ($1 → $52, $1,378), 52-week biggest first, 100 envelopes ($1 → $100, $5,050), 26 paychecks ($5 → $130, $1,755), the same amount every week, or your own (any number of deposits up to 366, increasing, decreasing or fixed, any schedule)
- Multiply any challenge to fit your budget: x2 saves $2,756 in 52 weeks, x5 saves $6,890
- Deposits: every deposit with its due date and amount; type Yes or x when it's done and it turns green, with a running total
- Progress: goal, saved, left, percent with a progress bar, deposits made, and ahead or behind schedule on any date
- Sample: a 52-week challenge started January 5: $100 saved by April 1, $9 ahead of schedule
Checked, not just designed: all 1,844 formulas recalculate with zero errors, and every deposit and total was checked against an independent calculation in 19 cases.
