Python 中的 numpy.fv()
哎哎哎:# t0]https://www . geeksforgeeks . org/num py-Fv-python/
numpy.fv(rate,nper,pmt,pv,when = 'end') : 该金融功能帮助用户计算未来价值。
参数:
利率:【标量或(M,数组)】每期十进制(非百分比)利率 nper : 【标量或(M,数组)】总复利期 pmt : 【标量或(M,数组)】固定支付 pv : 【标量或(M,数组)】现值 当:开始时(当= {'begin ',1})或结束时默认值为{'end ',0}
返回:
value at the end of nper periods
正在求解的方程:
fv + pv*(1+rate)**nper +
pmt*(1 + rate*when)/rate*((1 + rate)**nper - 1) == 0
或者当速率== 0 时
fv + pv + pmt * nper == 0

Question :
Future value after 10 years of saving $100 now,
with an additional monthly savings of $100.
Assume the interest rate is 5% (annually)
compounded monthly ?
'''
# rate np pmt pv
Solution = np.fv(0.05/12, 10*12, -100, -100)
print("Solution : ", Solution)
输出:
Solution : 15692.9288943
