Loan calculators are made of different calculation types. In fact, for calculating the same type of loans, a large number of different calculator programs exist that will help you think about your loan and analyze your loans from different angles.

I thought about making this post, but then decided it is bad karma to out the site I menioned, so I edited out the identifying details.
