Why is there variation in my returns?

Projected monthly returns are expected to remain relatively steady throughout the investment term, but there will be some slight variations based on the number of days in each statement period due to how interest is calculated and how principal is returned. Monthly returns are calculated on a daily basis, so for statement periods that have fewer days in the month (e.g., November only has 30 days while December has 31 days), you will see a smaller deposit.
