Installment(PRESENTVALUE,FUTUREVALUE,RATE,PERIODE)
Installment(NUMERIC VALUE,NUMERIC VALUE,NUMERIC VALUE,NUMERIC VALUE)
Installment(15000,0,10/12,60)

The installment function calculates the periodic installment payment required for a financial transaction given the presentvalue, futurevalue, interest rate, and number of payment periods.

If the installment payment increases the value of the investment (e.g., an annuity), the numeric value returned by the function is expressed as a positive amount. If the payment decreases the value of the investment (e.g., loan amortization), the numeric value returned by the function is expressed as a negative amount. The interest rate, installment payments, and time periods must be based on the same terms. For example, if payments are made monthly on a five-year loan, the number of periods is (12 * 5) or 60. The interest rate must be expressed in the same terms (the monthly interest rate is the annual rate /12). When typing fractions like 10 / 12, DataEase requires that you type a space before and after the / division symbol.

**PRESENTVALUE**

The value of the financial instrument today.

**FUTUREVALUE**

The value of the financial instrument at the end of the period.

**RATE**

The interest rate paid in the periode

**PERIODE**

Periode

A numeric value (the installment payment amount).

* futurevalue = principal * ((1 + (rate/100))) ** periods) + (installment/(rate/100)) * (((1 + (rate/100)) ** periods) - 1)*

The installment function calculates the periodic installment payment required for a financial transaction given the presentvalue, futurevalue, interest rate, and number of payment periods.
