nodeJS代码实现计算交社保是否合适

fuckShebao: function (req, res, next) {
        //每个月1800的社保
        var day = (1800 / 30);
        //交15年交满
        var full_days = 365 * 15;
        //到65岁退休
        var old_days= 365*35;
        var i = 0;
        var p = 0;
        var total = 0;
        //时光飞逝
        while (i < full_days) {
            total = total + day;
            i++;
            total = total + (total * 1.16 / 10000);
        }
        //15年后是那么多钱
        var year15 = total;
        //不再交了,继续放利息(余额宝)
        if (i == full_days) {
            while (p < (old_days-full_days)) {
                total = total + (total * 1.16 / 10000);
                p++;
            }
        }
        //结算出来:
        var all =  (total+"").toMoney();
        year15 = (year15 + "").toMoney();
        var re = {all: all, year15: year15};
        res.json(re);
    }
