“Recent user voice shows a thrilled sentiment. Users appreciate loan modeling and payoff strategies and accuracy and utility, but report feature limitations and calculation/logic issues.”
What Users Love
Gives you more flexibility with your payoff strategies.
I love how you can add extra principle payments in to see how quickly you can pay off your loan.
Straightforward data entry and gives all accurate calculations that match the bank’s.
Pain Points
I wish it would reach across all my platforms.
It doesn't allow for making a half payment twice a month.
Although I have set 'Tax' to be a dollar amount - the Calculator continues to report it as a percentage.
