  插值法是如何计算的 插值法的计算原理?

  Interpolation method is how to calculate the interpolation calculation principle?

  插值法是计算实际利率的一种方法.是使未来现金流量现值等于债券购入价格的折现率.插值法(或称插插补法、内插法)是财务分析和决策中常用的财务管理方法之一. 插值法的原理是根据比例关系建立一个方程,然后,解方程计算得出所要求的数据.济南代理记账公司

  Interpolation method is a method to calculate the real interest rates. Is to make the present value of future cash flows is equal to the bond discount rate of the purchase price. Interpolation method (or interpolation method, interpolation method) is commonly used in financial analysis and decision making of one of the financial management methods. The principle of interpolation method was established according to the proportional relationship between the equation, then the equation calculates the required data.

  假设与A1对应的数据是B1,与A2对应的数据是B2,现在已知与A对应的数据是B,A介于A1和A2之间,则可以按照(A1-A)/(A1-A2)=(B1-B)/(B1-B2)计算得出A的数值,其中A1、A2、B1、B2、B都是已知数据.

  Assumptions and corresponding data is B1, A1 and A2 corresponding data is B2, A corresponding data is now known as B, A between A1 and A2, can according to the (A1 - A)/(A1, A2) = (B1 - B)/(B1, B2) calculated by A numerical, A1, A2, B1, B2, B are known data.

  验证如下:根据:(A1-A)/(A1-A2)=(B1-B)/(B1-B2)可知:(A1-A)=(B1-B)/(B1-B2)×(A1-A2) A=A1-(B1-B)/(B1-B2)×(A1-A2)=A1+(B1-B)/(B1-B2)×(A2-A1)

  Validation is as follows: according to: (A1 - A)/(A1, A2) = (B1 - B)/(B1, B2) unknown: (A1 - A) = (B1 - B)/(B1, B2) x (A1, A2) A = A1 - (B1 - B)/(B1, B2) x (A1, A2) = A1 + (B1 - B)/(B1, B2) x (A2 - A1)

  例如某人向银行存入5000元,在利率为多少时才能保证在未来10年中每年末收到750元?

  Someone to the bank deposit 5000 yuan, for example, in the interest rate is how to ensure that in the next 10 years, received 750 yuan at the end of the year?

  5000/750=6.667 或 750*m=5000 查年金现值表 i=8%,系数为6.710 i=9%,系数为6.418 说明利率在8%-9%之间,设为x% (x%-8%)/(9%-8%)=(6.667-6.71)/(6.418-6.71)

  M = 5000/750 = 6.667 or 750 * 5000 annuity present value table I = 8% and the coefficient of 6.710 I = 9%, coefficient of 6.418 shows that interest rate between 8% and 9%, is set to x % (x % 8%)/(9% 8%) = (6.667 6.71)/(6.418 6.71)

  计算得出 x=8.147.

  X = 8.147 is calculated.
