Using SUMIF in Excel/Google Sheets

Question

I am creating a billable hours sheet in google sheets and would like to exclude line items that i set as not billable

In column B is the amount of hours worked
In column E is the rate per hour
In column D is Billable "Yes/No"
In Column F is Cost for that line item

Ideally I would like column F's total to be conditional based on column D's answer, so:

4 hours worked, at $20/hr, is billable would be $80
4 hours worked, at $20/hr, is NOT billable would be $0

Can someone please help me with the proper conditional SUMIF formula to get this started?

Answer 1

As follow up from comments, next formulas works in F2 and copied down:

=IF(D2="YES",B2*E2,0)

or

=B2*E2*(D2="YES")
