Calculating jQuery by txt fields

looking for a little help with my jQuery, (I know this is not the best)

Currently, there is a form divided into two sides, on the left I have a list of tips on the right - this is an obligation of some kind of balance for the account, see the image below

Balance sheet form

jquery is in use just now, a bit of a mess .. (sorry) this code will calculate the total field values ​​for each keyboard request that seems to work fine,

jQuery('#ass_cash, #ass_liquid, #ass_lifeinsu, #ass_covvalue, #ass_la1, #ass_la2, #ass_la3, #ass_realestate, #ass_auto1total, #ass_auto2total, #lib_mortgage, #lib_bankloan1, #lib_bankloan2, #lib_loansinsucomp, #lib_loanscreditunion, #lib_creditcards, #lib_od1, #lib_od2, #lib_od3, #lib_rent, #lib_mortgagemthpmt, #lib_bankloan1mthpmt, #lib_bankloan2mthpmt, #lib_loansinsucompmthpmt, #lib_loanscreditunionmthpmt, #lib_creditcardsmthpmt, #lib_od1mthpmt, #lib_od2mthpmt, #lib_od3mthpmt, #lib_rentmthpmt').keyup( function(){

});

you can see the section that causes the problems above, its calculation between the intermediate (minus) excess to generate the total,

each field for an asset has a class .asset each availability has a class. each monthly payment field has a .liabilitymth class

Ive jQuery ('. asset'). (function() , 2 ,

"readonly", .

. . : "" "". SURPLUS: ( -... '+') "" "-".

TOTAL ( ): "", , , , "" ().

MONTHLY-SURPLUS/DEFICIT: , (, "" ), " ".

, jQuery , , , :)

:

var totalAss = 0;
jQuery('.asset').each(function(){
    var value = parseFloat(this.value);
    if (value)
        totalAss += value;
});
jQuery('#ass_total').val(totalAss);

If you are performing a calculation in keyup or any other key events, then there will be a problem tracking old data that has been entered. For example, the moment you typed 50, and then you did it to 500, and then you did it to say 30. Then the key element will not be able to determine the difference between old and new data. You will have to write some logic to figure out old and new updated data, and then depending on this you will have to update the final value. Better if you can encode something like this ...
