Calculate lookup values against a calculated column and then sum.

Example:
Lookup results * calculated_column
14,15,17 * 9

SUM((14 * 9)+(15 * 9)+(17 * 9))

How can I do this?

It is a bit hard to tell what you want without names of fields, but I’m guessing that you have three lookup values and want to multiply them times a value in a fourth field, and store the final product in a fifth field.

You can add without using the SUM . Also use parenthesis to control the order of operations.

({lookup1} + {lookup2} + {lookup3}) * 9

If this isn’t what you want, try looking at the formula field reference.

Hi Airtable,I want it to take the lookup field values and multiply by a field.

array =14,15,25

14*field

15*field

25*field

Then sum results of this.

Is the array in a rollup or lookup?

If the array is in a lookup, create a rollup instead.

Then try this formula in the rollup:

SUM(values) * {field}

Although this formula calculates the sum first, you get the same result according to the distributive property.

(14 * field) + (15 * field) + (25 * field) = (14 + 15 + 25) * field

I verified the total should be 288 as you stated.

This is what I am getting.

9*32=272

{TOT HRS}*{LABOR-CST1}
and LABOR-CST1 comes from the function SUM({TECH-RATE})

9 * 32 most certainly isn’t 272.

Can you check how many decimal points you are displaying for {TOT HRS}, {LABOR-CST1}, and any other fields feeding into the calculations? It could be that the formula for either one is rounding the number to the nearest integer for display purposes, but using a different number in the actual calculations.

To echo @kuovonne, there needs to be a lot more detail in your description of the problem in order for us to provide meaningful assistance. Please describe in great detail:

  • What tables are involved in this setup
  • What fields are involved, including types and sample data
  • The specific formulas in any formula fields, and examples of the data being generated by them

It’s generally better to provide too much information than not enough.
