How this answer was worked out| Cost later | $180 |
| Expected later | 75% x $180 + 25% x $1,400 = $485 |
| Carrying cost | $0 x 12 = $0 |
| Earned by waiting | $180 x 0% x 12 / 12 = $0 |
| Putting it off costs | $485 + $0 - $0 = $485 |
| Waiting costs you | $485 - $180 = $305 |
| Per $1 put off | $2.69 |
| Break-even chance | 0% |
