Investopedia explains 'Marginal Propensity To Consume - MPC'

Let's illustrate this with an example. Suppose you receive a bonus with your paycheck, and it's $500 on top of your normal annual earnings. You suddenly have $500 more in income than you did before. If you decide to spend $400 of this marginal increase in income on a new business suit, your marginal propensity to consume will be 0.8 ($400 divided by $500).
