Complex Formula for Yearly Averages
I have a worksheet that has 8+ years worth of weekly rates (which are added
to each week). I am trying to calculate the 1 year, 3 year and 5 year averages. I need my spreadsheet to automatically calculate the average of 52 cells so each time I add a new weeks rate, it will change the source to read the most current 52 weeks. Also €“ my rates are in reverse order (oldest on top), so locking the cells wont work. Are there any formulas I can put in to do this? Thank you!! |
Complex Formula for Yearly Averages
Assuming no embedded blank cells, try this for last (latest) 52 week average:
=AVERAGE(INDIRECT("A" & COUNTA(A:A) & ":A" & COUNTA(A:A)-51)) To get 3 and 5 year average change 51 to 103 and 259 respectively HTH "Jen" wrote: I have a worksheet that has 8+ years worth of weekly rates (which are added to each week).
