Excel函数RATE如下; RATE(NPER,PMT,PV,FV,类型,猜测)

如果我不知道还款,如何知道开始和结束值,我怎么能让它工作?

贷款开始时说150,000美元,结束时0美元期限是300个月 .

我怎样才能获得利率?

    如果您现在收到150,000美元的300笔付款,每月566.67美元的费用,RATE的参数是:

    nper   - The number of periods over which the loan or investment is to be paid.
    pmt    - The (fixed) payment amount per period.
    pv     - The present value of the loan / investment.
    [fv]   - An optional argument that specifies the future value of the loan / investment,  
             at the end of nper payments. If omitted, [fv] takes on the default value of 0.
    [type]  - An optional argument that defines whether the payment is made at the start or  
              the end of the period. The [type] argument can have the value 0 or 1, meaning:  
              0 - the payment is made at the end of the period;
              1 - the payment is made at the beginning of the period.
              If the [type] argument is omitted, it takes on the default value of 0  
              (denoting payments made at the end of the period).
    [guess] - An initial estimate at what the rate will be.
              If this argument is omitted, it will take on the default value of 10% (=0.1)
    

    所以按照A2:F2中的单元格顺序说:
    nper 是300
    pmt 是-170,000 / 300即〜-5666.67(输入为 =ROUND(170,000/300,2)
    pv 是150,000
    fv 是0(默认值)
    type 您尚未指定,但可能是默认值(0)
    guess 我占1%(即.01)

    =RATE(A2,B2,C2,D2,E2,F2)
    

    返回 .085% . 这是每期(即每月)的费率,通常每年表示,通常乘以12,即每年给出1.02% . 在每年年底每年支付时,它与1.02%不完全相同,但这种低利率的每月复合对两位小数百分比没有显着差异 .

    它是1.0248%的有效利率,在12个等间隔,同等大小的分期中产生1.02%(第二个定义)1.02%,可以用以下公式计算:

    =NOMINAL(1.0248%,12)
    

    上述情况可以在TimeValue Software这样的网站上查看,该网站甚至提供完整的还款计划(尽管有一个舍入误差 - 小于1美元) .
