Formula to calculate cumulative interest

I want to calculate the amount of interest which would be earned over a
number of years. I will be starting with a base amount (say $25,000) which
will earn 8% interest compounded annually. I tried using the ACCRINTM
formula, but it isn't giving me the correct amount (which I figured out
manually).

My manual calculation showed that $25,000 earning 8% interest compounded
annually over 9 years would earn a total of $24,975 of interest. What
formula can I use to get Excel to do the calculation for me?

=FV(8%, 9, 0, -25000)

=FV(8%, 9,, -25000) - 25000
