numpy.fv(rate,nper,pmt,fv,當=“結束”時):此財務函數可幫助用戶計算未來價值。
參數:
-
rate : [數組]每個周期的利率為十進製(不是百分比)
nper : [數組]總複利期
pmt : [數組]固定付款
fv : [數組,可選]未來值。默認值= 0.0
when : 在每個期間的開始(當= {'開始',1}時)或結束(當= {'結束',0}時)。默認值為{‘end’,0}
返回:
present value as per given parameters.
求解方程:
fv + pv*(1 + rate)**nper + pmt*(1 + rate*when)/rate*((1 + rate)**nper - 1) = 0
或當費率== 0
fv + pv + pmt * nper = 0

## Python program explaining pv() function
import numpy as np
'''
Question :
What is the present value (e.g., the initial investment)
of an investment that needs to total $15692.93 after 10
years of saving $100 every month?
Assume the interest rate is 5% (annually) compounded monthly.
'''
# rate np pmt fv
Solution = np.pv(0.05/12, 10*12, -100, 15692.93)
print("present value (fv) : ", Solution)
輸出:
present value (fv) : -100.000671316
