What is an Effective Tax Rate?
Your effective tax rate represents the true average percentage of your income that goes to taxation:
Effective Tax Rate = (Total Tax Paid ÷ Total Gross Income) × 100
Because the US uses progressive tax brackets and provides generous standard deductions, your effective tax rate is almost always significantly lower than your top marginal bracket. For instance, a person in the 24% marginal bracket typically experiences an effective federal rate between 12% and 16%.
Frequently Asked Questions
Why is effective tax rate more useful than marginal rate?
Your effective tax rate reflects your true real-world tax burden and net take-home percentage. The marginal rate only matters when deciding whether to earn an additional dollar or make a pre-tax contribution.
