VBA Sum Solution

[Jl23]

I have a billing report that is generated with time, costs & totals for many projects each month. The issue is that there are not formulas generated with the report so if we have to make any adjustments to the time, the costs & totals associated don't automatically update. I'm looking for a macro that can be run to sum these various costs/total automatically as it is very time consuming to go back and insert formulas for each project. I'm new to coding so I'm struggling with how to do this since it's not just a solid range of data, need multiple formulas, & I need the formulas to be repeated for each project. I'm assuming a loop macro would need to be included? Below is an image of the data I'm working with and the formulas I'm trying do thru a macro. If anything is unclear please let me know & thanks in advance!

It is hard to work with a picture. It would be easier to help if you could use the XL2BB add-in (icon in the menu) to attach a screenshot (not a picture) of your sheet. Alternately, you could upload a copy of your file to a free site such as www.box.com or www.dropbox.com. Once you do that, mark it for 'Sharing' and you will be given a link to the file that you can post here. Explain in detail what you want to do referring to specific cells, rows, columns and sheets using a few examples from your data (de-sensitized if necessary).
