Effective Tax Rate
The effective tax rate is the average percentage of total income paid in taxes. Unlike the marginal tax rate, which applies only to the last dollar earned, the effective tax rate provides a comprehensive view of your total tax burden by dividing total tax paid by total income. It is always lower than the marginal tax rate in a progressive tax system.
Example
If you earn $75,000 and pay $12,000 in total income taxes, your effective tax rate is 16% ($12,000 / $75,000). Despite being in the 22% marginal tax bracket, your effective rate is lower because portions of your income are taxed at lower brackets (10% and 12%).
Frequently Asked Questions
What is the difference between effective and marginal tax rate?
The marginal tax rate is the rate applied to your last dollar of income (your highest tax bracket). The effective tax rate is your total tax divided by total income, representing your average tax rate. Effective rates are always lower than marginal rates in progressive systems.
Why does effective tax rate matter?
The effective tax rate gives you a realistic picture of your tax burden. When comparing salaries or tax situations across states or countries, the effective rate is more meaningful than the marginal rate for understanding your actual take-home pay.
