I would like to have one cell that will decrease in value by 1.5 every 1st
day of the month

Try...

=5000/(1.5^SUMPRODUCT(--(DAY(ROW(INDIRECT(DATE(2005,3,1)&":"&TODAY())))=1
)))*1.5

....where 5000 is the starting value used as an example, or...

=A1/(1.5^SUMPRODUCT(--(DAY(ROW(INDIRECT(DATE(2005,3,1)&":"&TODAY())))=1) )
)*1.5

....where A1 contains your starting value.

Note that I've used the first day of the current month as a starting
date [DATE(2005,3,1)]. If you're going to use another month as your
starting date, make sure that you use the first day of that month.

Hope this helps!

This'll last ya until the end of 2007:

=A1-MATCH(TODAY(),DATE(2005,ROW(INDIRECT("4:36")),1),1 )
*1.5

Array-entered, meaning press ctrl + shift + enter after
copying in the formula.

A few other notes:

*Assumes the value to decrement is in A1
*First time to decrement 1.5 is April 1, 2005.
*The formula will show #N/A until April 1, 2005.

.

=100-(1.5*INT((TODAY()-DATEVALUE("1/1/2005"))/30))
assuming that the starting value you want reduced by 1.5 is 100 and the
starting date is 1/1/05
