<p>I think that difference in BS/MS really depends on your field. I know for mine (materials) at my school it was generally closer to $5k-$10k. Also I know an MS is often sometimes seen by companies as a way of moving further up the ladder than someone with a BS.</p>
<p>You should also look to see if you can do your BS/MS in 4-4.5 years instead of 5. I know if I had dropped my physics minor I could have finished in 4, but I knew I was going to grad school, so I instead finished in 3.5 and saved a good deal in loans. One of my good friends went the other route and finished hers in 4. She wound up going to grad school, too, (needed to stay close geographically to her future husband). It let her get out of a handful of classes at her grad school, though she still had to take a bunch to get her second MS/fulfill PhD requirements.</p>
