var inputDiv = document.getElementById('start');
var startDate = moment();
var endDate = moment(inputDiv.innerHTML, "DD/MM/YYYY");
var result = 'Diff: ' + endDate.diff(startDate, 'days');
$('#result').html(result);

Moment is going to work as a datetime, so both of your dates are going to have a time associated with them.

var inputDiv = document.getElementById('start');
var endDate = moment(inputDiv.innerHTML, "DD/MM/YYYY"); // time of midnight (start of day), locally
var startDate = moment();  // time you run the code

So, endDate.diff(startDate, 'days') is going to calculate something akin to (tonight at midnight[locally]) - (today, midday[locally]). There is no full day difference in that equation.

Try either endDate.endOf('day').diff(startDate, 'days'), or better yet endDate.endOf('day').diff(startDate.endOf('day'), 'days').

Or you could just set var startDate = moment().startOf('day'); and use the code you have now.

Try "DD-MM-YYYY" instead of "DD/MM/YYYY"
