% change over instalments (not dates)

[Anonymous]

Hello, I wonder if it's possible to calculate percentage change over sequential numbered instalments, which are not dated?  The idea is that customers sign up to an open-ended plan and might cancel at any point.  I want to compare the number of customers who make their first payment to the number who make their second, third etc.

Here's a mock-up from Excel:

i.e. only 58% of customers make 6 or more payments, and 95% of those who make 5 payments will go on to make a sixth payment, etc.

Thanks in advance!

If you store the table as 2 columns . (instalment and makeP)

Then add 2 calculated columns as follows:

ColumnA = VAR _prevP = LOOKUPVALUE(TableQ[makeP], TableQ[instalment], TableQ[instalment] - 1)
RETURN
    DIVIDE(TableQ[makeP] , _prevP) 

ColumnB = VAR _prevP = LOOKUPVALUE(TableQ[makeP], TableQ[instalment],  1)
RETURN
    DIVIDE(TableQ[makeP] , _prevP) 

Please post sample data next time (not a picture). It always helps.
