When expanding the Current Loans line item to show the Loan Information details, the only interest component of the weekly payment provided is Interest Margin.
It can be financially efficient to trade out (refinance) old loans at higher interest rates to newer ones at lower rates. Without knowing the original interest rate along with the margin rate, that determination is somewhat more difficult.
The history graph only goes back almost two years, so one cannot rely on that, as loan terms can be as much as six years. Even if one could, it is manually intensive to correlate it all with the graph.
Perhaps it could be displayed similar to how the loan quote shows it.
Having that additional piece of information would make it easier to select candidates for refinance almost at a glance.
