Hi,
Please go through the usage for PMT, PPMT and IMPT for Loan Amortization.
PMT
Calculates the payment for a loan based on constant payments and a constant
interest rate.
Syntax
PMT(rate,nper,pv,fv,type)
For a more complete description of the arguments in PMT, see the PV function.
Rate is the interest rate for the loan.
Nper is the total number of payments for the loan.
Pv is the present value, or the total amount that a series of future
payments is worth now; also known as the principal.
Fv is the future value, or a cash balance you want to attain after the
last payment is made. If fv is omitted, it is assumed to be 0 (zero), that
is, the future value of a loan is 0.
Type is the number 0 (zero) or 1 and indicates when payments are due.
PPMT
Returns the payment on the principal for a given period for an investment
based on periodic, constant payments and a constant interest rate.
Syntax
PPMT(rate,per,nper,pv,fv,type)
For a more complete description of the arguments in PPMT, see PV.
Rate is the interest rate per period.
Per specifies the period and must be in the range 1 to nper.
Nper is the total number of payment periods in an annuity.
Pv is the present value — the total amount that a series of future
payments is worth now.
Fv is the future value, or a cash balance you want to attain after the
last payment is made. If fv is omitted, it is assumed to be 0 (zero), that
is, the future value of a loan is 0.
Type is the number 0 or 1 and indicates when payments are due.
IPMT
Returns the interest payment for a given period for an investment based on
periodic, constant payments and a constant interest rate. For a more complete
description of the arguments in IPMT and for more information about annuity
functions, see PV.
Syntax
IPMT(rate,per,nper,pv,fv,type)
Rate is the interest rate per period.
Per is the period for which you want to find the interest and must be in
the range 1 to nper.
Nper is the total number of payment periods in an annuity.
Pv is the present value, or the lump-sum amount that a series of future
payments is worth right now.
Fv is the future value, or a cash balance you want to attain after the
last payment is made. If fv is omitted, it is assumed to be 0 (the future
value of a loan, for example, is 0).
Type is the number 0 or 1 and indicates when payments are due. If type is
omitted, it is assumed to be 0.
Set type equal to If payments are due
0 At the end of the period
1 At the beginning of the period
Remarks
Make sure that you are consistent about the units you use for specifying
rate and nper. If you make monthly payments on a four-year loan at 12 percent
annual interest, use 12%/12 for rate and 4*12 for nper. If you make annual
payments on the same loan, use 12% for rate and 4 for nper.
For all the arguments, cash you pay out, such as deposits to savings, is
represented by negative numbers; cash you receive, such as dividend checks,
is represented by positive numbers.
