Type (optional): defines the due date. F=1 for payment at the beginning of a period and F=0 for payment at the end of a period.

In the LibreOffice Calc functions, parameters marked as "optional" can be left out only when no parameter follows. For example, in a function with four parameters, where the last two parameters are marked as "optional", you can leave out parameter 4 or parameters 3 and 4, but you cannot leave out parameter 3 alone.

How high is the periodic monthly payment at an annual interest rate of 8.75% over a period of 3 years? The cash value is 5,000 currency units and is always paid at the beginning of a period. The future value is 8,000 currency units.

PPMT(8.75%/12;1;36;5000;8000;1) = -350.99 currency units.

## CUMPRINC

Returns the cumulative interest paid for an investment period with a constant interest rate.

Type (optional): the due date for the periodic payments. Type=1 is payment at the beginning and Type=0 is payment at the end of each period.

In the LibreOffice Calc functions, parameters marked as "optional" can be left out only when no parameter follows. For example, in a function with four parameters, where the last two parameters are marked as "optional", you can leave out parameter 4 or parameters 3 and 4, but you cannot leave out parameter 3 alone.

What are the periodic payments at a yearly interest rate of 1.99% if the payment time is 3 years and the cash value is 25,000 currency units. There are 36 months as 36 payment periods, and the interest rate per payment period is 1.99%/12.

## NPV

RATE: the discount rate for a period.

Value1, Value2, ..., Value30 are up to 30 values, which represent deposits or withdrawals.

What is the net present value of periodic payments of 10, 20 and 30 currency units with a discount rate of 8.75%. At time zero the costs were paid as -40 currency units.

NPV(8.75%;10;20;30) = 49.43 currency units. The net present value is the returned value minus the initial costs of 40 currency units, therefore 9.43 currency units.

## SLN

Returns the straight-line depreciation of an asset for one period. The amount of the depreciation is constant during the depreciation period.

SLN(COST; SALVAGE; LIFE)

Cost is the initial cost of an asset.

SLN(50000;3,500;84) = 553.57 currency units. The periodic monthly depreciation of the office equipment is 553.57 currency units.
