| What the name means | "Annual Payment of an annuity allowing for different periodicity of payments per year"
| | Syntax | PmtM ( PresentValue, InterestAER, TermYrs, PmtsPerYear, [FVOpt] )
| | Description | Calculates the annual rate of payment of a simple annuity, taking into account that the annual payments specified may take place during the course of the year.
| | See Also | FVM (AnnPmt, PresentValue, InterestAER, TermYrs, PmtsPerYear) | | IntRateM (AnnPmt, PresentValue, TermYrs, PmtsPerYear, [FVOpt]) | | PVM (AnnPmt, InterestAER, TermYrs, PmtsPerYear, [FVOpt]) | | TermM (AnnPmt, PresentValue, InterestAER, PmtsPerYear, [FVOpt])

Inputs: (5)
|
| 1
| PresentValue
| Float
| The Net Present Value
|
| 2
| InterestAER
| Float
| Interest Rate expressed as an AER, Annual Equivalent Rate. See Annual Equivalent Rates
|
| 3
| TermYrs
| Float
| Term in years of loan, lease etc
|
| 4
| PmtsPerYear
| Float
| Number of payments Per Year (eg +4 = qtrly in advance, -4 = qtrly in arrear)
|
| 5
| FVOpt
| Float (Optional)
| The future value (optional). FV is the cash balance you would want to attain on the last payment. because of endemic confusion over the sign of FV (we use the same convention as Microsoft), we recommend it is omitted or zero.
(Optional)

Mathematical Formula |  | Methodology | Sign Convention: BF follows Excel's sign convention, which can occasionally cause confusion.
- The PV of a +ve annual payment is -ve.
- The PV of a -ve annual payment is +ve.
- The FV of a +ve annual payment or a +ve PV is -ve.
- The FV of a -ve annual payment or a -ve PV is +ve.
The reason for this is that Excel uses the following equation to calculate PV's:
This is highly logical, but be aware of the apparent swapping in sign, particularly if you are using or solving for FV's, where the confusion gets more pronounced. Sorry about this, but we need to be compatible with Excel! |
