Comprehensive
This is, by far, the most complete mortgage calculator I have ever found, online or otherwise. Though not intuitive, it is very useful for those looking to generate mortgage-specific numbers, like the front-end/back-end ratio; I used it while reading articles, etc. When I bought a house. I tried many other mortgage calculators, and this is the one I always came back to.
