Excel function question

[jj]

I need to create an exception report where I can flag 5% exceptions with a *
sign.
Example:
B and C are columns with dollar amounts
b1 $100
C1 $300
I need D1 to show a * since c1 deviates more than 5% from b1.
How do I do that?

Try in D1
=if(abs(c1-b1)/b1>0.05,"*","")
