Function pmt

pmt(rate: number, nper: number, pv: number, fv?: number, type?: 0 | 1): number
Calculates the payment for a loan based on constant payments and a constant interest rate.

Remarks:
- The payment returned by this function includes principal and interest but no taxes, reserve payments, or fees sometimes associated with loans.
- 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 an annual interest rate of 12 percent, use 0.12 / 12 for rate and 4 * 12 for nper. If you make annual payments on the same loan, use 0.12 for rate and 4 for nper.
Parameters
- rate: number
  The interest rate for the loan.
- nper: number
  The total number of payments for the loan.
- pv: number
  The present value, or the total amount that a series of future payments is worth now; also known as the principal.
- Optionalfv: number = 0
  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.
- Optionaltype: 0 | 1 = 0
  The number 0 (zero) or 1 and indicates when payments are due. Set type equal to 0 or omitted if payments are due at the end of the period. Set type equal to 1 if payments are due at the beginning of the period.
Returns number
The periodic payment amount.
