If you have Excel 2007: *=AVERAGEIF(A:A,""&MAX(A:A)-14,B:B)

Earlier versions: * =SUMIF(A:A,""&MAX(A:A)-14,B:B)/COUNTIF(A:A,""&MAX(A:A)-14)

Hi, and thanks.

This formula works fine: =AVERAGEIF(A:A,""&MAX(A:A)-14,B:B)

This formula I could not get to work:
=AVERAGE(OFFSET(B22,-13,0,14,1))

Thanks for the quick responses.
