First of all, it was not clear in your initial posting that "10.000" was
intended to be interpreted as a percentage. That might be why David's
solution is not working for you. You could write:

=B1 * min(A1%,5%)

But personally, I think it would be better if you entered 10% into A1, and
formatted the cell as Percentage with the desired number of decimal places,
if necessary.

Second, I am sensing that you might not understand the MIN() function and
why it does exactly what you requested. The above is a more efficient way
of writing:

=B1 * if(A1% < 5%, A1%, 5%)

or if you prefer:

=if(B1*A1% < B1*5%, B1*A1%, B1*5%)

The latter says exactly what you wrote in your first posting, namely: "the
formula for saying A * B but not greater than B * .05"

The MIN() function returns the smallest of its arguments, which can more
than 2, by the way.

Does that help?

Whatever value you have for A1 will be used in the formula.

Thanks, David. What if A is variable?
