Najbolj splošno:
donos
R = ----------
vlaganje


Primer: dobiček 2.862 , povprečni trajni kapital 32.864 ( ki ga dobimo, kot aritmetično sredino stanj 1.1. in 31.12)

Torej 2865 x 100 : 32864 = 8,72 Pomeni da je podjetje na enoto vloženega kapitala ustvarilo 8,7 enot dobička.

Sem kaj pomagala?

Konkretno vase formule ne poznam. Poznam pa formulo za izracun
ČISTE DONOSNOSTI SREDSTEV =

čisti dobiček / čista izguba
------------------------------ x 100 (v %)
povprečna sredstva

ČISTA DONOSNOST KAPITALA =

čisti dobiček / čista izguba
----------------------------- x 100 (v %)
povprečni kapital

Upam, da ti bo v pomoč.

Ja tako je. Donos je dobiček, vlaganja so pa kapital ali pa sredstva.

Koilkor je meni znano, se interna stopnja donosnosti uporablja za izračun stopnje donosnosti, pri kateri se stroški oziroma izdatki za naložb (s tem je mišljena vrednost investicije) izenači z vrednostjo prejemkov iz opazovane naložbe v času ekonomske dobe naložbe. To pomeni, da iščeš diskontno stopnjo , ki bo izenačila sedanjo vrednost donosov sedanjo vrednostjo investicijskih stroškov. Če to iščeš "ročno", priporočam uporabo metode interpolacije (priznam, v excelu še tega nisem delala). Enačba:

ISD= p+((NSV1*(i-p)/(NSV1+NSV2)
Za detajle izračuna in pomenov gornjega čudeža priporočam sicer nekoliko staro, vendar še vedno uporabno literaturo dr. Drago Filipič-a: "Osnove poslovnih financ"

Hvala za pomoč, vsi nasveti so uporabni!

Tole je v angleščini in za Excel. Upam, da koristi.

IRR

Returns the internal rate of return for a series of cash flows represented by the numbers in values. These cash flows do not have to be even, as they would be for an annuity. The internal rate of return is the interest rate received for an investment consisting of payments (negative values) and income (positive values) that occur at regular periods.

Syntax
IRR(values, guess)
Values is an array or a reference to cells that contain numbers for which you want to calculate the internal rate of return. Values must contain at least one positive value and one negative value to calculate the internal rate of return. IRR uses the order of values to interpret the order of cash flows. Be sure to enter your payment and income values in the sequence you want. If an array or reference argument contains text, logical values, or empty cells, those values are ignored. Guess is a number that you guess is close to the result of IRR.

Microsoft Excel uses an iterative technique for calculating IRR. Starting with guess, IRR cycles through the calculation until the result is accurate within 0.00001 percent. If IRR can"t find a result that works after 20 tries, the #NUM! error value is returned. In most cases you do not need to provide guess for the IRR calculation. If guess is omitted, it is assumed to be 0.1 (10 percent). If IRR gives the #NUM! error value, or if the result is not close to what you expected, try again with a different value for guess.

Examples

Suppose you want to start a restaurant business. You estimate it will cost $70,000 to start the business and expect to net the following income in the first five years: $12,000, $15,000, $18,000, $21,000, and $26,000. B1:B6 contain the following values: $-70,000, $12,000, $15,000, $18,000, $21,000 and $26,000, respectively.

To calculate the investment"s internal rate of return after four years: IRR(B1:B5) equals -2.12%
To calculate the internal rate of return after five years: IRR(B1:B6) equals 8.66%
To calculate the internal rate of return after two years, you need to include a guess: IRR(B1:B3,-10%)
equals -44.35%
Remarks

IRR is closely related to NPV, the net present value function. The rate of return calculated by IRR is the interest rate corresponding to a zero net present value. The following macro formula demonstrates how NPV and IRR are related: NPV(IRR(B1:B6),B1:B6) equals 3.60E-08 (Within the accuracy of the IRR calculation, the value 3.60E-08 is effectively 0.)
