IPMT (Rate,Period,NoPaymentPeriods,PresentValue,FutureValue,Type)

• $Rate$ is the annual rate of interest.
• $Period$ is the period of to find the interest rate.
• $NoPaymentPeriods$ is the number of installments.
• $PresentValue$ is the present value.
• $FutureValue$ is the future value.
• $Type$ is either 1 or 0.
  • IPMT(), returns the interest payment for an investment for a given period.

Description

• This function gives amount of interest for a particular time, according to the periodic, fixed payments and fixed interest rate.
• This function can be used to calculate the payments for a loan or the future value of an investment.
• In $IPMT(Rate,Period,NoPaymentPeriods,PresentValue,FutureValue,Type)$, where $Rate$ is the rate of interest for a year
• $Period$ is the period for which the interest payment is to be calculated. It must be a value between $1$ and $NoPaymentPeriods$.
• $NoPaymentPeriods$ is the total number of periods over which the loan or investment is to be paid.
• $PresentValue$ is the present value of the loan.
• $FutureValue$ is the future value of the loan, at the end of $NoPaymentPeriods$ payment.
• $Type$ is the number $0$ or $1$.
• When type value is $0$ means the payment is made at the end of the period and type value is $1$ means the payment is made at the beginning of the period
• Here the arguments $FutureValue$ and $Type$ are optional.
• Suppose we omit the value of $FutureValue$, then it will consider the value as $0$.
• Also when we are not giving the $Type$ value, the default value is $0$.
• Suppose we calculate the monthly payments instead of annual payment, for the argument $Rate$ we have to divide by $12$ and the $np$ value we have multiply with $12$.
• For e.g. The monthly payments on a 5 year loan at 10% annual interest, we have to give the arguments $Rate$ and $NoPaymentPeriods$ as 10%/12 for $Rate$ and 5*12 for $NoPaymentPeriods$.
• This function will give result as error when

Any one of the argument is non-numeric
$Period<0$ or $period>NoPaymentPeriods$

ZOS

• The syntax is to calculate amount of interest for a particular time in ZOS is

$IPMT(Rate,Period,NoPaymentPeriods,PresentValue,FutureValue,Type)$

• • $Rate$ is the annual rate of interest.
  • $Periods$ is the period of to find the interest rate.
  • $NoPaymentPeriods$ is the number of installments.
  • $PresentValue$ is the present value.
  • $FutureValue$ is the future value.
  • $Type$ is either 1 or 0.
• For e.g.,

Examples

• 1.Calculate the interest payment during half yearly 1 and 2 of a loan for 50,000, that is to be reduced to 10,000 over a period of 3 years, by a series of constant half-yearly payments.
• Interest is charged at a rate of 4.5% per year and the payment is made at the beginning of each half year.
• IPMT(4.5%/2,3,2*2,50000,10000,1)= -454.78404196736113
• 2.The interest payment for a $55000 investment that earns 7.50% annually for 15 years.
• The interest payment is calculated for the 5th year and payments are due at the end of each year.

IPMT(7.5%/1, 5, 15*1, 55000)=-3418.570
