How consumption and saving are related to disposable income?

Consumption and saving are directly related to disposable income, which is the amount of income available for spending or saving after taxes. As disposable income increases, individuals tend to consume more goods and services, but they may also save a portion of that income. The marginal propensity to consume (MPC) indicates the proportion of additional disposable income that is spent on consumption, while the marginal propensity to save (MPS) represents the proportion that is saved. Thus, the balance between consumption and saving is influenced by changes in disposable income levels.
