The calculations may not accurate to the cents level due to rounding. I

User entry error handling is minimal, so watch your inputs!
The user interface should be easy to figure out. One thing that is not

For example, 1/3 means year 1, month 3. Entering 1 alone means year 1. For
programmers, take note the dates are 1-based!
