Goal seek issue

[max1995]

I have a sheet (Attached), where I want to change the value of the total billable hours to reach a target utilization, but it's not working properly, appreciate any pointers.

A	B	C	E	F	G	H	I	J	K
From 1/7/2023 to 30/8/2023	Working Days	Target Hours Available for Work	To be charged
62	496	180
Name	Total hours charged	Billable	Total Billable	Non-billable	Total Non-billable	Utilization %	Target
Dep.A	Dep.B	Dep.A	Dep.B
ABC​	316	15	108	123	105	88	193	24.8%	70%
				Change this				Actual utilization	To get to this target

Wouldn't your formula be Total hours charged(316*.70) = 221.2?
