How this answer was worked out| Cost later | $400 |
| Expected later | 70% x $400 + 30% x $2,200 = $940 |
| Carrying cost | $0 x 6 = $0 |
| Earned by waiting | $400 x 4% x 6 / 12 = $8 |
| Putting it off costs | $940 + $0 - $8 = $932 |
| Waiting costs you | $932 - $400 = $532 |
| Per $1 put off | $2.33 |
| Break-even chance | 0.4% |
