Try this:

For a value in A1

B1: =MAX(CEILING(A1,16),64)

Does that help?

I'm looking for a formula that will allow me to type in a number and roundup
to the largest multiple of 16 with a minimum of 64.

For example, if I type in 60 in Cell A1, then in cell A2 I want it to
roundup to 64.

Thanks.
