How it works
A savings challenge sets a deposit for each week, envelope or paycheck. In the 52-week challenge you save $1 in week 1, $2 in week 2 and so on up to $52: 1 + 2 + … + 52 = $1,378. The 100-envelope challenge fills envelopes marked $1 to $100 in any order, $5,050 in all. Multiply any challenge to fit your budget: at ×5 the 52-week challenge saves $6,890. The calculator lists every deposit with its date from your start date.
