If you've ever thought about taking out a mortgage then naturally you will want to do the sums to make sure it's worth your effort. And unless you have a degree in finance or you're unccanily gifted in the mathematics department you'll find that calculating the costs can be quite overwhelming.

Today many banks or financial institutions offer their own versions of online mortgage or loan calculators but there are also an increasing amount of websites designed specifically for this purpose. Mortgage-Calc.com has not only mortgage calculators but debt consolidation calculators, refinancing calculators and even a "How long until you're a millionaire?" calculator.
