The interest accrued in any period is:

=FV(3.92%/365, n,, -prevBalance) - prevBalance

where "n" is the number of days in the period. The best
way to determine "n" is to compute the number of days
using actual dates. That will adjust correctly for 28, 29,
30 and 31-day periods. Example:

A1=2/3/2006
C1=1500
A2=3/3/2006
B2=FV(3.92%/365,A2-A1,,-C1)
C2=C1+B2
A3=4/3/2006

Be sure that column B and C are formatted as Currency
with 2 decimal places. Copy B2:C2 to B3:C3, then drag
A2:C3 (two rows) down through the term of the CD.
