public static void main(String args[]){

int money=200;

int year=1;

double rate=0.1;

for(;year<=20;year++){

int allbenjin=money*12*year;

double allmoney=getAllMoney( money, year, rate);

double allrate=allmoney/allbenjin;

System.out.println("本金:"+allbenjin+">复利总收益：>>"+allmoney+"资产增加率为=="+allrate);

}

/**

* 获取复利总收入

* @param money 每月投入本金

* @param year 投入年份数

* @param rate 年利率

* @return

* 计算结果：

投资年限到期本金收益和：75603

投资年限到期总收益：51603

资产增加率：215.01%

M=12a(1+x)[-1+(1+x)^n]/x

M：预期收益

a：每月定投金额

x：一年收益率

n：定投期数(公式中为n次方)

public static double getAllMoney(int money,int year,double rate){

double allmoney=0;

allmoney=12*money*(1+rate)*(-1+Math.pow((1+rate), year))/rate;

return allmoney;

}
