Python 中的 numpy.pmt()
numpy.pmt(rate, nper, pv, fv, when = ‘end’) : 该金融功能帮助用户按照本金和利息计算支付价值。
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)】总复合期 fv : 【标量或(M，数组)】未来值 pv : 【标量或(M，数组)】当前值 当:开始时默认值为{'end '，0}
返回:支付值
正在求解的方程:
Fv+PV (1 +费率)nper + pmt(1 +费率当)/费率(1+费率)* * nper–1)= 0
或者当速率== 0 时T2【Fv+PV+PMT * nper = = 0
代码:
# Python program explaining
# pmt() function
import numpy as np
'''
Question :
monthly payment needed to pay off a $10, 000 loan
in 12 years at an annual interest rate of 10 %
'''
# rate np pv
Solution = np.pmt(0.10 / 12, 12 * 12, 10, 000)
# Here fv = 0 ; Also Default value of fv = 0
print("Solution : ", Solution)
输出:
Solution : -0.1195078262827336
