*In PPMT(r,pe,np,pv,fv,ty), r is the rate of interest for the period.

*In <math>PPMT(r,pe,np,pv,fv,ty)</math>, <math> r </math> is the rate of interest for the period.

*Suppose we are taking  a loan for 8 percent annual interest rate and paying the amount in monthly, then the r value is 8%/12. So we have to enter the r value as  8%/12 or 0.6667% or 0.006667 in to the formula as the rate.

*Suppose we are taking  a loan for 8 percent annual interest rate and paying the amount in monthly, then the <math> r </math> value is 8%/12. So we have to enter the <math> r </math> value as  8%/12 or 0.6667% or 0.006667 in to the formula as the rate.

*pe indicates the period and it is lying with in 1 to nper.

*<math> pe </math> indicates the period and it is lying with in 1 to nper.

*np is the total number of payment periods in an annuity.

*<math> np </math> 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.

*<math> pv </math> is the present value-the total amount that a series of future payments is worth now.

*fv is the future value of an investment or loan (the value you want to achieve at the end of all periods) when we are omitting the value of fv ,then it is assumed to be 0.  

*<math> fv </math> is the future value of an investment or loan (the value you want to achieve at the end of all periods) when we are omitting the value of <math> fv </math> ,then it is assumed to be 0.  

*ty is the number 0 or 1 which is specifies the time to make a payment during the period.  

*<math> ty </math> is the number 0 or 1 which is specifies the time to make a payment during the period.  

*when we are not giving the value of ty, then it is assumed to be 0.

*when we are not giving the value of <math> ty </math>, then it is assumed to be 0.
