The response from Elika was most helpful. You must assume communal living during that Levitical period.
In transferring the cost to American dollars today I would suggest discussing it with a beef farmer raising 100 or more head. Initially you can find a young female beef cow at a fair for around $200. Bulls are more expensive (maybe like $300). Assuming then that you buy the acreage and equipment to feed and raise 100 head, startup cost can come to $30,000 to $50,000. But, a fully functional farm with the supply of cattle, land, and equipment cost the farmer $6 to $12 a day per head to maintain.
Everyone thinks that buying a house is a large purchase (and it is). Yet after the down payment and mortgage, you don't daily live in that house for the initial cost you spent. In the same way, the maintenance of a large herd of animals starts high in price, but your herd can grow exponentially within several years and ultimately make a profit. To the Israelite the cost of a sacrificial animal could be as little as the $6 you spent to feed it that day, but you're also sacrificing future livestock and the amount of time you spent raising that calf until old enough to be slaughtered.
I would look at it in terms of percent of the total herd you were sacrificing. Say the Israelites owned a herd as large as 2,000 to 3,000 head. Sacrificing 250 animals a year is only 8% of your herd. My guess is as the herd grew by at least 4% a year, the amount of sacrifices was much more significant.
