31-day challenge kept on 80% of days, then a weekly no-spend habit:
| Usual spending per day | January challenge (80% of days) | 2 no-spend days/week for a year | 4 no-spend days/week for a year |
|---|---|---|---|
| $10 | $248.00 | $1,040 | $2,080 |
| $20 | $496.00 | $2,080 | $4,160 |
| $25 | $620.00 | $2,600 | $5,200 |
| $40 | $992.00 | $4,160 | $8,320 |
| $60 | $1,488.00 | $6,240 | $12,480 |
