Paycheck Calculator
计算在联邦税、FICA、州税和税前扣款后的净实得工资。
基于2024年美国税率的估计值。实际结果可能有所不同。请咨询税务专业人士获得准确计算。
关于此工具
薪资计算器帮助您准确了解扣除税款和扣除后实际到手的金额。无论是在进行薪资谈判、规划月度预算，还是想知道为什么薪资比预期少，这个工具都会为您分解联邦所得税、FICA缴款（社会保障和医疗保险）、州税以及401(k)或健康保险费等税前扣除的计算过程。获得准确的实际收入数字对于进行现实的财务规划至关重要。
使用计算器时，请输入您的年总收入（或时薪和每周工作小时数），选择申报身份，然后输入您拥有的任何税前扣除。该工具会自动应用2024年联邦税级距和标准扣除额，然后计算FICA税率（社会保障6.2%、医疗保险1.45%）和适用的州税率。您还可以模拟不同情景——如果您增加401(k)缴款会怎样？如果您增加加班时间会怎样？——以查看这些变化如何影响您的实际收入。
此计算器对于员工比较工作机会、规划月度开支或理解工资单扣除最为有用。请记住，这是基于标准税率的估计值；您的实际薪资可能会因您雇主的特定工资单系统、额外的地方税或最近的税法变化而略有不同。对于复杂的税务情况——自营业收入、投资收益或多份工作——建议咨询税务专业人士以获得更详细的情况。
