Formula to spread cost of hired equipment between weekly periods?

[thbutterflycollector_]

Hi,

I'm trying to compare budget against actual against several cost codes. Part of the analysis requires me to look at hired equipment and I am required to compare spends vs budgets in weekly periods. I am trying (based on the anticipated or known on and off hire dates) to "spread" the liability up to a certain period end:

Can anyone assist in guiding me on how to spread the costs listed in Column N between Columns R and Z? Some consumable items (shown in row 3) are also included and purchased as a one-off which also require factoring in.

Is this possible without a VBA? Hopefully someone can assist me.

Thanks
