If you look at the loan screen it shows ‘hourly interest’, however this is actually daily interest (otherwise it appears you’re accruing more interest than you’re actually paying off!)
So in this example the interest rate is 0.59% (daily) so the daily interest would be 0.0059 x $258,000 = $1,522 (close enough to the $1,531 it shows). Either the label needs to say ‘daily interest’ or the figure changed. Personally I think showing daily repayment and daily interest would make more sense. On that note could we have a ‘pay off’ button to clear a loan?
