If you don t need to support IE8 then you can use the native Javascript Array prototype reduce   method  You will need to convert your JQuery object into an array first    var sum       price   toArray   reduce function sum element         if isNaN sum   sum   0       return sum   Number element value       0     Reference  https   developer mozilla org en-US docs Web JavaScript Reference Global Objects Array Reduce

Similarly along the lines of these answers written as a plugin     fn sum   function          var sum   0      this each function              sum    1    this  val                 return sum       For the record 1   x is faster than Number x  in Chrome
