Return Month-on-Month growth using current month-prior month/prior month per country

Hello

In the Period tab, I'd like to return the Month-on-Month growth per Fiscal Period for each country, by using the data from the Budget tab comparing prior month to current month. So for example, for Period's 2020P9 for Country AU, I need a formula that calculates the month-on-month growth (in %) by looking at the increase/decrease. So (28-32)/28. 28 being AU's numbers for prior month, 2020P8, and 32 being AU's numbers for current month

Thanks

I think if you want period growth, for AU Period 2020P9 it would be (32-28)/28, right?
Now, if your years were always the same on both sheets (like they are now) and if the list of countries was in the same order (like it is now), you could simply use this formula in C8 and then copy it down and across:
=(Budget!E2-Budget!D2)/Budget!D2

If they were more mixed up, you could try this formula in cell C8. You can copy this down and across.

=(INDEX(Budget!$D$2:$AA$17,MATCH(Period!$A8,Budget!$A$2:$A$17,0),MATCH(Period!C$7,Budget!$D$1:$AA$1,0))-INDEX(Budget!$D$2:$AA$17,MATCH(Period!$A8,Budget!$A$2:$A$17,0),MATCH(Period!C$7,Budget!$D$1:$AA$1,0)-1))/INDEX(Budget!$D$2:$AA$17,MATCH(Period!$A8,Budget!$A$2:$A$17,0),MATCH(Period!C$7,Budget!$D$1:$AA$1,0)-1)

Thanks for that, looking for the increase from prior month always, so I think the second one is the one I'm after
