    Has everything I need.
  • by David 10/8/2014
    Extremely fast and fluid. Very well designed UI. lots of calcs. I was mainly interested in mortgage ones. Excited to see ability to compare 3 different loans side by side. However none of the calcs have ability to factor in additional payments and see more powerful mortgage scenarios
