The difference matters. Your marginal rate tells you how much tax a pay rise, bonus or extra shift will attract. Your effective rate, which is always lower, tells you the share of your whole income that goes to tax. Only the dollars inside the top bracket you reach are taxed at the top rate, because the brackets are progressive.
