Here is a way to use calculated field in Kendo Grid.

var crudServiceBaseUrl = "http://demos.telerik.com/kendo-ui/service",
dataSource = new kendo.data.DataSource({
    transport: {
        read: {
            url: crudServiceBaseUrl + "/Products",
            dataType: "jsonp"
        }
    },
    pageSize: 20,
    schema: {
        model: {
            total: function (item) {
                return this.UnitPrice * this.UnitsInStock;
            }
        }
    }
});

$("#grid").kendoGrid({
    dataSource: dataSource,
    pageable: true,
    height: 550,
    sortable: true,
    filterable: true,
    toolbar: ["create"],
    columns: [
        { field: "UnitPrice", title: "Unit Price"},
        { field: "UnitsInStock", title: "Units In Stock", width: "120px" },
        { field: "total()", title: "Total" }]
});
