The state at which a consumer derives maximum utility from the consumption of one or more goods and services given his/her level of income is called consumer's equilibrium.
Consumer equilibrium can be regarded as a particular point that point at a consumer will reach where he derived so much utility from a commodity or at the peak of utility derivation.
At a particular fixed level of income and price of that commodity.
It should be noted that at this point, it will be difficult for a consumer to deviate.
