Python numpy.rate()用法及代码示例


numpy.pmt(rate,nper,pv,fv,当=“结束”时):此财务函数可帮助用户计算每个期间的利率。

参数:
nper: [scalar or (M, )array] total compounding periods
pmt : [scalar or (M, )array] Payment
fv : [scalar or (M, )array] Future value
pv : [scalar or (M, )array] present value
when: at the beginning (when = {‘begin’, 1}) or the end (when = {‘end’, 0}) of each period. Default is {‘end’, 0}

返回: Rate of interest per period.



求解方程:

fv + pv*(1+rate)**nper + pmt*(1 + rate*when)/rate*((1 + rate)**nper - 1) == 0

or when rate == 0
fv + pv + pmt * nper == 0

代码:

# Python program explaining  
# rate() function  
import numpy as np  
  
  
#                 nper  pmt   pv   fv  
Solution = np.rate(6, 10000, 500, 200)  
  
print("Solution= rate ", Solution) 

输出:

Solution= rate  -2.024705182882783
