how to calculate based on dates?
 

I want to calculate whether total payments are ahead or behind of schedule.

Column A is for Dates.

Column L is the difference between J$6 and J(whatever selected row). The
number in Column L gets
larger, row by row.

I want to have a Column M that calculates how much the figures in column L
are ahead or behind
plan. The plan is for column L to increase at 53 per day.

The entries and the dates entered in Column A are not daily (or in any
regular periodic sequence),
but they are chronological of course.

Working with the dates is confusing me -- can anyone help?!

Thanks,
Jack

Perhaps this table (if it shows up right) will make things clearer:

J
K
L
M

Date
Total credit debt
Amt of credit debt reduced
Cummula-tive credit reduction
Credit reduction ahead or behind (-)

Well, that post didn't work out -- see the table at

I guess I thought it was harder than it really is.

This seems to work [Column L is the difference between J$5 and J(whatever
selected row)]:

=IF(ISNUMBER(L6),($A$5-A6)*53+L6,"")
