Depends:
Primers right now are ranging from $8-18 bucks a hundred.
Powder is from $40-70bucks a pound.
Projectiles from $45-100 for a hundred.
SO: to load 100 rounds you would average 1LB = 7000 grs. of powder So 7000/50grs per round = 140 rounds @ $60 bucks for powder= ~.43 cents + ~.10cents per primer + ~.50 for your bullet = ~$1.03 per round.
Plus the cost of the tooling to make that loading - trimmer, de-primer, re-primer, sizer, meter out powder, bullet seater, etc. Cheap, cheap like I started with - Lee Loading tool might be $40 or $50 these days - uses a scoop to measure out your powder - no choice of load - have to use the included chart for the various bullet weight - will only neck size, so often will not work for your rifle with cases previously fired in another rifle. My most recent purchase was an RCBS Chargemaster Lite - so that was just over $400 delivered to my mailbox. Plus press, dies, etc. - so could spend $1,000 or more in tooling I am sure, by the time you include some way to anneal the brass, etc.
These are my rough calculations from about a year ago.
Cost per round
308
Varget 60$ per pound +tax
Sierra Tmk 175 , 71.99+tax
Large rifle primers 10$/100
Winchester brass 44.99/ 50 +tax
43 grains per load
50c powder per load
Bullets 81c each
11c primers
Brass 51c
Total
With brass- 1.92
Without brass- 1.41
I can get Sellier + Belloit 180gr cartridges here for 1.35. Why not just buy those instead of reload?

Handloading is an interesting hobby in its own right. The by-product is useful if you are a shooter.
Who cares about cost? If the wife asks, do what the rest of us do - lie.
