PMT

The PMT function calculates the payments for a loan based on constant payments and a constant interest rate.

Syntax

PMT(Rate,Nper,PV,FV?,Type?) - > Number

Arguments

Arguments	Datatype	Description
Rate	Number, Node reference	The interest rate per period.
Nper	Number, Node reference	The total number of periods.
PV	Node reference	The present value or initial investment. Cash outflows are considered as negative and cash inflows as positive.
FV?	Node reference	The future or residual value. This is an optional argument and if omitted, it is considered to be zero.
Type?	Number	Indicates when the payments are made. Type is zero if payments are made at the end of the period and non-zero if payments are made at the start of the period. This is an optional argument and when omitted, it is considered to be zero.

Example

Consider a $10,000 loan at an annual rate of 10% that is to be paid off in 1.5 years. All payments are made at the beginning of the month.

To calculate the monthly payments that are to be made, the formula should be written in the [PMT] node:

PMT( 0.83% ,[Number of periods],[Loan Amount],0,1)

We are dividing the annual rate by 12 to get the period rate.
