Financial Functions Part One
This category contains the mathematical finance functions of LibreOffice Calc.
ACCRINT
Calculates the accrued interest of a security in the case of periodic payments.
Syntax
ACCRINT(Issue; FirstInterest; Settlement; Rate; Par; Frequency; Basis)
Issue (required) is the issue date of the security.
FirstInterest (required) is the first interest date of the security.
Settlement (required) is the date at which the interest accrued up until then is to be calculated.
Rate (required) is the annual nominal rate of interest (coupon interest rate)
Par (optional) is the par value of the security.
Frequency (required) is the number of interest payments per year (1, 2 or 4).
Example
A security is issued on 28/02/2001. First interest is set for 31/08/2001. The settlement date is 01/05/2001. The Rate is 0.1 or 10% and Par is 1000 currency units. Interest is paid halfyearly (frequency is 2). The basis is the US method (0). How much interest has accrued?
=ACCRINT("28/02/2001";"31/08/2001";"01/05/2001";0.1;1000;2;0) returns 16.94444.
ACCRINTM
Calculates the accrued interest of a security in the case of oneoff payment at the settlement date.
Syntax
ACCRINTM(Issue; Settlement; Rate; Par; Basis)
Issue (required) is the issue date of the security.
Settlement (required) is the date at which the interest accrued up until then is to be calculated.
Rate (required) is the annual nominal rate of interest (coupon interest rate).
Par (optional) is the par value of the security.
Example
A security is issued on 01/04/2001. The maturity date is set for 15/06/2001. The Rate is 0.1 or 10% and Par is 1000 currency units. The basis of the daily/annual calculation is the daily balance (3). How much interest has accrued?
=ACCRINTM("01/04/2001";"15/06/2001";0.1;1000;3) returns 20.54795.
AMORDEGRC
Calculates the amount of depreciation for a settlement period as degressive amortisation. Unlike AMORLINC, a depreciation coefficient that is independent of the depreciable life is used here.
Syntax
AMORDEGRC(Cost; DatePurchased; FirstPeriod; Salvage; Period; Rate; Basis)
Cost is the acquisition costs.
DatePurchased is the date of acquisition.
FirstPeriod is the end date of the first settlement period.
Salvage is the salvage value of the capital asset at the end of the depreciable life.
Period is the settlement period to be considered.
Rate is the rate of depreciation.
AMORLINC
Calculates the amount of depreciation for a settlement period as linear amortisation. If the capital asset is purchased during the settlement period, the proportional amount of depreciation is considered.
Syntax
AMORLINC(Cost; DatePurchased; FirstPeriod; Salvage; Period; Rate; Basis)
Cost is the acquisition costs.
DatePurchased is the date of acquisition.
FirstPeriod is the end date of the first settlement period.
Salvage is the salvage value of the capital asset at the end of the depreciable life.
Period is the settlement period to be considered.
Rate is the rate of depreciation.
DB
Returns the depreciation of an asset for a specified period using the fixeddeclining balance method.
This form of depreciation is used if you want to get a higher depreciation value at the beginning of the depreciation (as opposed to linear depreciation). The depreciation value is reduced with every depreciation period by the depreciation already deducted from the initial cost.
Syntax
DB(Cost; Salvage; Life; Period; Month)
Cost is the initial cost of an asset.
Salvage is the value of an asset at the end of the depreciation.
Life defines the period over which an asset is depreciated.
Period is the length of each period. The length must be entered in the same date unit as the depreciation period.
Month (optional) denotes the number of months for the first year of depreciation. If an entry is not defined, 12 is used as the default.
Example
A computer system with an initial cost of 25,000 currency units is to be depreciated over a three year period. The salvage value is to be 1,000 currency units. One period is 30 days.
=DB(25000;1000;36;1;6) = 1,075.00 currency units
The fixeddeclining depreciation of the computer system is 1,075.00 currency units.
DDB
Returns the depreciation of an asset for a specified period using the arithmeticdeclining method.
Use this form of depreciation if you require a higher initial depreciation value as opposed to linear depreciation. The depreciation value gets less with each period and is usually used for assets whose value loss is higher shortly after purchase (for example, vehicles, computers). Please note that the book value will never reach zero under this calculation type.
Syntax
DDB(Cost; Salvage; Life; Period; Factor)
Cost fixes the initial cost of an asset.
Salvage fixes the value of an asset at the end of its life.
Life is the number of periods (for example, years or months) defining how long the asset is to be used.
Period defines the length of the period over which the value is to be calculated. The period must be entered in the same time unit as Life.
Factor (optional) is the factor by which depreciation decreases. If a value is not entered, the default is factor 2.
Example
A computer system with an initial cost of 75,000 currency units is to be depreciated monthly over 5 years. The value at the end of the depreciation is to be 1 currency unit. The factor is 2.
=DDB(75000;1;60;12;2) = 1,721.81 currency units. Therefore, the doubledeclining depreciation during the twelfth month after purchase is 1,721.81 currency units.
DISC
Calculates the allowance (discount) of a security as a percentage.
Syntax
DISC("Settlement"; "Maturity"; Price; Redemption; Basis)
Settlement is the date of purchase of the security.
Maturity is the date on which the security matures (expires).
Price is the price of the security per 100 currency units of par value.
Redemption is the redemption value of the security per 100 currency units of par value.
Example
A security is purchased on 20010125; the maturity date is 20011115. The price (purchase price) is 97, the redemption value is 100. Using daily balance calculation (basis 3) how high is the settlement (discount)?
=DISC("20010125";"20011115";97;100;3) returns about 0.0372 or 3.72 per cent.
DURATION_ADD
Calculates the duration of a fixed interest security in years.
Syntax
DURATION_ADD("Settlement"; "Maturity"; Coupon; Yield; Frequency; Basis)
Settlement is the date of purchase of the security.
Maturity is the date on which the security matures (expires).
Coupon is the annual coupon interest rate (nominal rate of interest)
Yield is the annual yield of the security.
Frequency is the number of interest payments per year (1, 2 or 4).
Example
A security is purchased on 20010101; the maturity date is 20060101. The Coupon rate of interest is 8%. The yield is 9.0%. Interest is paid halfyearly (frequency is 2). Using daily balance interest calculation (basis 3), what is the duration?
=DURATION_ADD("20010101";"20060101";0.08;0.09;2;3)
EFFECTIVE
Returns the net annual interest rate for a nominal interest rate.
Nominal interest refers to the amount of interest due at the end of a calculation period. Effective interest increases with the number of payments made. In other words, interest is often paid in instalments (for example, monthly or quarterly) before the end of the calculation period.
Syntax
EFFECTIVE(Nom; P)
Nom is the nominal interest.
P is the number of interest payment periods per year.
Example
If the annual nominal interest rate is 9.75% and four interest calculation periods are defined, what is the actual interest rate (effective rate)?
=EFFECTIVE(9.75%;4) = 10.11% The annual effective rate is therefore 10.11%.
EFFECT_ADD
Calculates the effective annual rate of interest on the basis of the nominal interest rate and the number of interest payments per annum.
Syntax
EFFECT_ADD(NominalRate; NumPerYear)
NominalRate is the annual nominal rate of interest.
NumPerYear is the number of interest payments per year.
Example
What is the effective annual rate of interest for a 5.25% nominal rate and quarterly payment.
=EFFECT_ADD(0.0525;4) returns 0.053543 or 5.3543%.
IRR
Calculates the internal rate of return for an investment. The values represent cash flow values at regular intervals, at least one value must be negative (payments) and at least one value must be positive (income).
If the payments take place at irregular intervals, use the XIRR function.
Syntax
IRR(Values; Guess)
Values is an array containing the values.
Guess (optional) is the estimated value. An iterative method is used to calculate the internal rate of return. If you can provide only few values, you should provide an initial guess to enable the iteration.
Example
Under the assumption that the cell contents are A1=10000, A2=3500, A3=7600 and A4=1000, the formula =IRR(A1:A4) gives a result of 11.33%.
Because of the iterative method used, it is possible for IRR to fail and return Error 523, with "Error: Calculation does not converge" in the status bar. In that case, try another value for Guess.
ISPMT
Calculates the level of interest for unchanged amortisation instalments.
Syntax
ISPMT(Rate; Period; TotalPeriods; Invest)
Rate sets the periodic interest rate.
Period is the number of instalments for calculation of interest.
TotalPeriods is the total number of instalment periods.
Invest is the amount of the investment.
Example
For a credit amount of 120,000 currency units with a twoyear term and monthly instalments, at a yearly interest rate of 12% the level of interest after 1.5 years is required.
=ISPMT(1%;18;24;120000) = 300 currency units. The monthly interest after 1.5 years amounts to 300 currency units.
PV
Returns the present (current) value of an investment resulting from a series of regular payments.
Use this function to calculate the amount of money needed to be invested at a fixed rate today, to receive a specific amount, an annuity, over a specified number of periods. You can also determine how much money is to remain after the elapse of the period. Specify as well if the amount is to be paid out at the beginning or at the end of each period.
Enter these values either as numbers, expressions or references. If, for example, interest is paid annually at 8%, but you want to use month as your period, enter 8%/12 under Rate and LibreOffice Calc with automatically calculate the correct factor.
Syntax
PV(Rate; NumPeriods; Payment; FV; Type)
Rate defines the interest rate per period.
NumPeriods is the total number of periods (payment period).
Payment is the constant payment made each period.
FV (optional) defines the future value remaining after the final instalment has been made.
Type (optional) denotes due date for payments. Type = 1 means due at the beginning of a period and Type = 0 (default) means due at the end of the 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.
Example
What is the present value of an investment, if 500 currency units are paid out monthly and the annual interest rate is 8%? The payment period is 48 months and 20,000 currency units are to remain at the end of the payment period.
=PV(8%/12;48;500;20000) = 35,019.37 currency units. Under the named conditions, you must deposit 35,019.37 currency units today, if you want to receive 500 currency units per month for 48 months and have 20,000 currency units left over at the end. Crosschecking shows that 48 x 500 currency units + 20,000 currency units = 44,000 currency units. The difference between this amount and the 35,000 currency units deposited represents the interest paid.
If you enter references instead of these values into the formula, you can calculate any number of "Ifthen" scenarios. Please note: references to constants must be defined as absolute references. Examples of this type of application are found under the depreciation functions.
RECEIVED
Calculates the amount received that is paid for a fixedinterest security at a given point in time.
Syntax
RECEIVED("Settlement"; "Maturity"; Investment; Discount; Basis)
Settlement is the date of purchase of the security.
Maturity is the date on which the security matures (expires).
Investment is the purchase sum.
Discount is the percentage discount on acquisition of the security.
Example
Settlement date: 15th February 1999, maturity date: 15th May 1999, investment sum: 1000 currency units, discount: 5.75 per cent, basis: Daily balance/360 = 2.
The amount received on the maturity date is calculated as follows:
=RECEIVED("19990215";"19990515";1000;0.0575;2) returns 1014.420266.
SYD
Returns the arithmeticdeclining depreciation rate.
Use this function to calculate the depreciation amount for one period of the total depreciation span of an object. Arithmetic declining depreciation reduces the depreciation amount from period to period by a fixed sum.
Syntax
SYD(Cost; Salvage; Life; Period)
Cost is the initial cost of an asset.
Salvage is the value of an asset after depreciation.
Life is the period fixing the time span over which an asset is depreciated.
Period defines the period for which the depreciation is to be calculated.
Example
A video system initially costing 50,000 currency units is to be depreciated annually for the next 5 years. The salvage value is to be 10,000 currency units. You want to calculate depreciation for the first year.
=SYD(50000;10000;5;1)=13,333.33 currency units. The depreciation amount for the first year is 13,333.33 currency units.
To have an overview of depreciation rates per period, it is best to define a depreciation table. By entering the different depreciation formulae available in LibreOffice Calc next to each other, you can see which depreciation form is the most appropriate. Enter the table as follows:

The formula in E2 is as follows:
=SYD($A$2;$B$2;$C$2;D2)
This formula is duplicated in column E down to E11 (select E2, then drag down the lower right corner with the mouse).
Cell E13 contains the formula used to check the total of the depreciation amounts. It uses the SUMIF function as the negative values in E8:E11 must not be considered. The condition >0 is contained in cell A13. The formula in E13 is as follows:
=SUMIF(E2:E11;A13)
Now view the depreciation for a 10 year period, or at a salvage value of 1 currency unit, or enter a different initial cost and so on.
