The marginal efficiency of capital is called the expected return of capital or expected rate of profit on an investment.
PV = R + R + R + …………… + R (1+i) (1+i) (1+i) (1+i)
Keynes define the marginal efficiency of capital as “ MEC is being equal to that rate of discount which make the present value of the series of annuities given by the returns expected from the capital during its life just equal to its supply price. From the above equation and definition we can conclude that marginal efficiency of capital is inversely related to present value of an investment.
1. Rate of interest:-
The investment decision that depends not only marginal efficiency of capital but on the interest rate as well. Marginal efficiency is the gain from an investment while interest rate is the cost of an investment.
