# Help with a monthly percentage formula

Hey guys, So I have a list of total monthly salary for each person. The trouble is each person is split among 16 jobs with various percentages. Is there a simple formula to sum all of the salary devoted to each job without building out monthly calculations for each project?

My data is arranged as cell A3-L97 is the monthly salaries then columns N3-AD97 is the percentage spent on a particular job. All I am trying is a formula to calculate salary based on each job per month.

Any ideas or do I need to build it out?

Best way to learn Power Query?
Read M is for (Data) Monkey book by Ken Puls and Miguel Escobar. It is the complete guide to Power Query.
can you copy/paste a sample of your data so we can see it? if it's confidential info then just change the names etc.

I assume that columns N:AD represent the jobs. FYI, that is 17 jobs, not 16. I assume that columns A:L represent the months. And rows 3:97 represent the employees (95).

So one design might be: enter the job names into N99:AD99 and the month names into M100:M111. Then enter the following formula into N100 and copy N100 into N100:AD111:

=SUMPRODUCT(INDEX(\$A\$4:\$L\$97, 0, ROWS(M\$100:M100)), N\$4:N\$97)

The result might look something like this, representing only 5 employees (rows 4:8):

 A B - K L M N O - AC AD AE 3 Jan Feb - Nov Dec TOTAL Job1 Job2 - Job16 Job17 TOTAL 4 \$1,500 \$500 - \$700 \$1,200 \$12,200 0% 2% - 6% 10% 100% 5 \$900 \$900 - \$1,200 \$1,500 \$11,200 3% 2% - 1% 9% 100% 6 \$1,400 \$1,400 - \$800 \$1,100 \$12,600 5% 5% - 5% 4% 100% 7 \$1,300 \$1,000 - \$700 \$1,400 \$12,200 5% 8% - 7% 7% 100% 8 \$1,100 \$500 - \$600 \$1,100 \$10,900 2% 7% - 11% 11% 100% 9 - \$59,100 - - - 98 - - 99 - Job1 Job2 - Job16 Job17 100 - Jan \$184 \$299 - \$381 \$499 101 - Feb \$157 \$213 - \$234 \$312 110 - Nov \$123 \$176 - \$209 \$325 111 - Dec \$192 \$298 - \$361 \$518 112 - TOTAL \$1,794 \$2,837 - \$3,527 \$4,785 \$59,100
