the formula breakdowns next to each result are super helpful, kind of wish more calculator sites did that. tried a couple of finance ones and they worked perfectly
Love that every result actually shows the formula behind it - I learned something about my mortgage calc instead of just getting a number. The sheer variety is wild too.
