Calculate instalment amounts by each instalment date

[Kirsten22]

Hi,

I am looking to create a measure that would calculate the installment amount each week by account. Below is an example of the data. I need to be able to see when each instalment occurs and the value of the instalment for each account. So account A would have a $5k instalment on 10/08, 10/09, 10/10, and 10/11.

I would like to put the results in a graph that would show the week commencing date on the x-axis and the sum of the total instalments across all accounts for that week as the value.

Does anyone know of a good solution for this?

Account	Number of Instalments	Instalment Amount	First Instalment Date
A	4	$                          5,000	10/08/2022
B	4	$                          2,500	4/08/2022
C	5	$                          3,000	31/07/2022
D	3	$                          4,000	28/07/2022
E	4	$                          5,000	1/08/2022
F	4	$                          2,500	4/08/2022

Hi @Kirsten22 ,

Based on this, the format of date column seems to be dd/mm/yyyy, so for Account A,First Instalment Date=August 10, not October 8 , right?

Please transform the table in Power Query:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUTIBYgUVBZzAVMfAwACoxtBA38BC38jAyEgpVidayYkIrUY6pmCtJig6nYEipgR0GkMtNTbUNzBHaHUBCRHQagLVamSBotWVFK+iuNeNPJ/GAgA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Account = _t, #"Number of Instalments" = _t, #"Instalment Amount" = _t, #"First Instalment Date" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Account", type text}, {"Number of Instalments", Int64.Type}, {"Instalment Amount", Currency.Type}, {"First Instalment Date", type text}}),
    #"Changed Type with Locale" = Table.TransformColumnTypes(#"Changed Type", {{"First Instalment Date", type date}}, "en-GB"),
    #"Added Custom" = Table.AddColumn(#"Changed Type with Locale", "Instalment Date", each [
end=Date.AddDays([First Instalment Date],[Number of Instalments]-1),
l={Number.From([First Instalment Date])..Number.From(end)}
][l]),
    #"Expanded Instalment Date" = Table.ExpandListColumn(#"Added Custom", "Instalment Date"),
    #"Changed Type1" = Table.TransformColumnTypes(#"Expanded Instalment Date",{{"Instalment Date", type date}})
in
    #"Changed Type1"

Output:

@Kirsten22 , In case this is a month , then generate end date

end date = date(year([First Instalment Date]), month([First Instalment Date]) +[Number of Instalments], Day([First Instalment Date]) )

Then you use the attached file or blog - https://community.powerbi.com/t5/Community-Blog/How-to-divide-distribute-values-between-start-date-o...

Not if they days 7, week. Then use the power query solution in blog - Duration -7 Days and not need of date diff you already have a number of installment

example : List.Dates([First Instalment Date], [Number of Instalments] ,#duration(7,0,0,0) )
