Adding Column B, when Column A has specific data

Hi,
I'm new to this forum and i've been working with excel for many years, but now I'm starting to become more advanced and using formulas more.

My problem is
I have column A with employees intitals or employee numbers

Column AColum B
AF$100.00
DF$420.00
DR$75.00
EE$101.00
PR$542.25

I have column B with amounts that reflect loans to these individuals. Every several months I would like to print out a list of what they owe.

How can I sum column B and have it itemized for all the loans made for employee AF or DF in column A. I know this might be basic, but wasted about 2 hours trying myself.
Thanks in advance for your help

You can use Pivot table to autocategorize and autosum

or you can list the column A items and use SUMIF formula
