I was looking at a post that had 2,000,000 of 7% 10 year bond and it came up with 2,125,000. I calculated the interest at 140,000

The 140,000 is the annual interest payment. That doesn't mean it's a correct answer, because I don't know if it's an annual payment, nor do I know if the question is asking for the payment or the expense, which is two different things. There's interest payment and there's interest expense, and all you said was interest.

Since you didn't actually ask a question, but rather just gave us some info, I don't have any idea what you're supposed to be doing or what you need to know. Nor do I know what post you're referring to, nor am I going to try to go find it. If you want answers to stuff related to other posts, link to the post.

(Amazing how often we're to be mind readers.)
