## how to calculate ratio between two table

hello. I have two tables in which there are many accouting records from accounting journal.

I want to calculate ratio between left table (account number 112) and right table (account 8520 ). indeed it should be calculated as (account 112) / (account 8520)).

what i did was to create a new query from left table in which I make summarization by account number "112" and then make a physical relation via Bridge table to right table.

But I have about 103 ratio between diffrent accounts!!! and hence it is not rational to create a new query for each of them.

instead,I want to summarize left table by special account number (for each ratio) via DAX and then make a virtual relation between that summurized table to the right table.

How can i do that?

i think there should be a optimal way.

## Re: how to calculate ratio between two table

Hi @dombarg

I make a test to describe what I don’t understand.

1.“I have about 103 ratio between diffrent accounts”

It means you need make summarization by account number "112",”113”,”114”……   right?

column “sum1” will get the sum of amount left table based on different account.

column “sum2” will get the sum of amount right table based on different account.

sum1 = CALCULATE(SUM(Sheet1[amount]),ALLEXCEPT(Sheet1,Sheet1[account]))

sum2 = CALCULATE(SUM(Sheet2[amount]),ALLEXCEPT(Sheet2,Sheet2[account]))

Then for ratio=A/B

A-> sum1

B-> sum2

2.“make a physical relation via Bridge table to right table”

I don’t know what’s the physical relation via Bridge table to right table.

I manage the relationship between left table and right table with column “ID”, as this column contains mutiple repetitive values, so I make a bridge table with each unique value.

Best Regards

Maggie

Hi @dombarg

What exactly is the rule to calculate ratio between left table and right table?

Does the following example meet your requirement?

## Re: how to calculate ratio between two table

thank u @v-juanli-msft .

```ratio =
DIVIDE (
CALCULATE ( [sum of amounnt left table], account = 112 ),
CALCULATE ( [sum of amounnt right table], account = 8520 )
)```

it will be reapeted for another accounts.for example :

124/8790 and etc....

year as slicer and citiy as axis bar.

(right table has many duplicated avalue too.but in the screenshut  it is uniqe)

## Re: how to calculate ratio between two table

Wow thank u.it is so simple.i thought it should be very complex 😄 .thank u.i made some changes to your answer:

```test for new method =
DIVIDE (
CALCULATE ( SUM ( 'bs'[amount] ), 'bs'[account] = "8520" ),
CALCULATE ( SUM ( 'INCOME'[amount] ), 'INCOME'[account] = "102" )
)```

just,would u please explain how filter in this Bridge flows through tables?
