The US federal income tax uses marginal brackets: each additional dollar of income is taxed at the rate of the bracket it falls into, not the rate of your highest bracket. Your effective (average) rate is always lower than your marginal rate.

Most people — including most retirees — misunderstand how brackets work. "I don't want a raise, it'll push me into a higher bracket" is one of the most persistent myths in personal finance. Understanding marginal vs effective rates is the foundation of every tax decision in retirement.
In retirement, your "real" marginal rate can be much higher than your stated bracket because of Social Security taxation and IRMAA. A dollar of Roth conversion at the 12% bracket can actually cost 22.2% because it also makes more SS taxable.
