In setting out the basic processes that create a tendency for the rate of profit to fall, which simultaneously causes the mass of profit to rise, Marx outlined the way these very same processes also result in a tendency for the rate of profit to rise. So, the basis of the tendency for the rate of profit to fall is that the total value of constant capital rises relative to the total value of variable capital. But, the means by which this comes about is technological change. New, more efficient means of production raise the productivity of labour, so that a given quantity of labour can process a greater quantity of material.
However, this very same process also creates a tendency for the rate of profit to rise. Firstly, it means that a smaller quantity of fixed capital is required relative to the quantity of material processed, because one new machine replaces several older machines. Secondly, this same process also reduces the value of that fixed capital, which, because it must always be present for production to take place, must always be included in the advanced capital. The combination of a relative fall in the quantity of fixed capital, and an absolute fall in its value, is a powerful factor, therefore, in creating a tendency for the rate of profit to rise, which counteracts its tendency to fall. Thirdly, this same rise in productivity causes the value of the circulating constant capital to fall, though in respect to material this frequently occurs in steps, only after new production has been established. It is frequently only as an average market price, over many years, that this can be observed, as market prices remain high during periods of under supply, and then fall to below prices of production, during periods of over supply.
So, although the quantity of material processed increases, the total value of that material may rise by only a small amount, remain the same, or even fall as a result of the fall in the value of the material itself. Moreover, changes in technology and technique may also result in the material itself being used more efficiently, so that even a relatively smaller quantity of it is consumed. For example, improvements in steam engine technology continually resulted in more power being produced with smaller amounts of coal consumed to produce it. The same thing is seen today. Global GDP has risen by seven times the increase in oil consumption, since the 1980's, as technology has improved the way oil is used to produce energy.

These huge reductions in the quantity of materials used, and in the value both of the fixed and circulating constant capital, thereby create a powerful tendency for the rate of profit to rise.
Fifthly, the same processes also result in significant falls in the value of wage goods, which causes the value of labour-power to fall and relative surplus value to rise. The increase in the rate of surplus value, therefore, also creates a tendency for the rate of profit to rise.
Sixthly, the increase in productivity reduces the production time and circulation time of capital so that the rate of turnover rises, thereby causing the annual rate of profit to rise.
Finally, these same processes result in the creation of new industries, where the organic composition of capital is lower and of profit is higher.
