Hi folks,
Would appreciate some help in locating a formula to calculate compound 
interest on an increasing principal.
Many thanks

Moreden,

If you add to the principal at a constant rate, and the interest rate 
doesn't change, then simple use the FV function.  Otherwise, you need to use 
a stepwise method, using a table of variable inputs to FV at every change in 
rate or principal addition.
