3. General Formulae for Price Calculations 
Every price (of any type) consists of three
basic components: material costs, wages and profits. If we denote
p
..... price
c .....
materials costs
v .....
wage costs z ..... profit
we can write this relation in the following way:
p = c + v + z (0)

To this should be noted:
a) in order to simplify the computation we do not take into consideration the distribution margin,
b) all ^{"}non cost^{"} components of the price are included into the profit,
c) in order to attain greater accuracy a fourth component (indirect tax) should be added to the price of some commodities, but as we are interested in price calculations of uniform level, we need not take the indirect tax into account. 
The substance of price calculations consists in recalculation of all prices — under the condition that technology, i.e.. e. material consumption and productivity of labor does not change  in such a way that the amount of ^{"}z^{" }(profit) in all prices should correspond to a chosen uniform principle. The price calculation according to a uniform base practically equals the redistribution of surplus product among the different branches of production. 
The difficulty of this task consists not in the redistribution of
surplus product alone (this could be computed easily) but in consequences of
price interdependencies; as soon as prices start to ^{"}move^{"},
the price expression of costs will change (even if a constant physical
structure of output is considered), so that in order to obtain a required
price, we have to add the share of surplus product calculated by the new method
to the costs, the amount of which however depends on prices we have still in
process of calculation. 
In price calculations it is thus always necessary to take into account the changes in valuation of material costs. The change of wage costs could be, of course, taken into account as well; even under unchanged input of labor it could happen that the changes in prices of consumption goods will enforce the change of the amount of wages and consequently of wage costs per production unit. In order to express these changes mathematical models have been already elaborated. But it must be stated that these models are very complicated and, besides this, the empirical data which could make possible our computations are not yet at our disposal. Owing to this, there is no other choice than a somewhat less accurate but much more simple way: to consider the component v (wage costs) of every price as constant and at the same time to make sure that the real contents of nominal wages (at least approximately) will not be subject to changes during price recalculations. This could be done, e.g. by postulating the sum of prices of consumer goods, which are purchased for wages, to be constant. We shall return to this problem in discussing the so called (n + 1)st condition. 
If we sum up our considerations, we have to establish — for obtaining prices of a uniform base — the formulae and the calculation methods so that they:
1) are based on the technologically given input structure, including direct labor input (expressed in wage costs);
2) enable the redistribution of surplus product into the prices according to the above mentioned general rules;
3) contain revaluation of material costs (in the case of production, two channel, and incomeprices the revaluation of production funds as well) in terms of prices of a uniform base. This has to be understood as revaluation which itself is part of calculation and not an additional revaluation adjustment;
4) retain the nominal amount of wage costs and real contents of wages as the only unchanging, constant element of price structure 
Now we can proceed to the construction of formulae
for particular types of a uniform price base. 
Labor
Value price.
Surplus
product realized in every branch equals the produced surplus product. Therefore
z = m, where
m
is the produced surplus product
contained in the commodity unit. At the same time it is supposed that the rate
of surplus product, m=m/v is in all branches equal. These _{.}two
assumptions imply that the profit (z) in every price — see formula (1) — is a
multiple of
wage costs (v). Therefore
z =
m v
(1)
After substitution into
(0)
and a small adjustment we obtain the general formula of value price:
p = c + v(1+
m)
(2)

Cost price. If r is the rate of profit, r = z /(c + v) , then from the assumption of a uniform rate of profit follows that z in every price is r multiple of the amount of costs z = r (c + v) . After substituting into (1) and after some adjustment we obtain
p = (c + v)(1 + r)^{ } (3)^{} 
Production price.
Redistribution of surplus product according to uniform rate of profit
is supposed. Let us denote the rate of profit
as
r
and
the stock of production funds (evaluated in production prices) needed to
produce a unit of production in a given branch as K. K
is also denoted as a coefficient of funds‑intensity
of production. Therefore, the rate of profit is
r =
z / K
;_{
}the principle of a uniform rate of profit implies that the
profit contained in every price is a multiple of the fundsintensity
coefficient:
z
=
r K.
It follows therefore that the general formula of production price is
p = c + v +
r K
(4)
It has to be noted that the calculations must respect the fact that the
fund coefficient of production necessarily varies with price changes; this
happens not only in the case of the production price but also in the cases of
the twochannel price and income price as well. 
The two  channel price The twochannel price can be calculated in several alternatives: Let us assume here the following alternative: a portion of surplus product is apportioned into the prices as the so called interest on the production funds — it is proportionate to the production funds according to a uniform rate of interest; the rest is apportioned in relation to the wage costs. The twochannel price formula accordingly contains instead of z (see 1) two terms: the first one is similar to that in the value price (2), the second to that in the production price (4). The only difference is the substitution of the rate of profit r_{ }by the rate of interest — let us denote it r*  and of the rate of surplus product m by the reduced rate of surplus product m*. By the reduced rate of surplus product is understood the coefficient by means of which not the whole surplus product in the community, but only the part of surplus product, remaining after the deduction of the whole amount of interests on the production funds, is apportioned. The formula of the twochannel price is then as follows:
p = c + v(1 + m*) +_{ }
r*K
(5)
This formula makes it clear that the price relations here are a certain
^{"}weighted average^{"} of value relations and
production prices. The greater is
m*
and accordingly the smaller is the interest
of funds
r*,
the
nearer are the twochannel prices to the value prices (for
r*
=
0 they are equal to the value prices), and, on
the contrary, the greater is the interest and the smaller the reduced rate of
surplus product, the nearer are the twochannel prices to the production prices
(for m*
= 0
they
are equivalent to the production prices). 
Income price Income price is based on the idea of a uniform rate of gross income in relation to production funds. If we denote the gross income as d where d = v + m and the rate of gross income as d , d = d / K , then the simple formula of income price reads:
p = c + d K (6)
