How can I round up the users input to the next thousand using javascript?

I am creating a title fee calculator and they need every dollar to round up to the next thousand.
I have used  < input onblur="this.value=1000*Math.round(this.value/1000)"> to round the user's input  to the nearest thousand, but I need it to go to the next thousand.  When I alter it with Math.round(this.value/1000)+1 it works perfectly.  18,200 goes to 19,000, which is desirable.  However, 19,000 will go to 20,000, which is not desirable.  I need the numbers that are already an even thousand to stay an even thousand.  The calculator I'm creating goes to 1,000,000.00, so I need a way for when the user enters an even thousand number such as 220,000 it will remain 220,000.  but if they enter 220,001 it needs to go to 221,000.
I am attaching my form and code.  Is there something I'm missing, or is there an easier way to achieve the correct premium amount?
Any help would be greatly appreciated, I've been working on this WAY too long.

i.e.

<input onblur="this.value=1000*Math.ceil(this.value/1000)">
