Paychecks can often feel confusing, especially when you notice the difference between your gross pay (before deductions) and your net pay (take-home pay). For employees in Oregon, various state and federal taxes, as well as benefit deductions, affect the final amount you actually receive.
ADP Oregon Paycheck Calculator
How Does the ADP Oregon Paycheck Calculator Work?
The calculator uses both federal tax laws and Oregon-specific tax rules to estimate net pay. It factors in:
- Gross pay (hourly wage × hours worked, or annual salary ÷ pay periods)
- Federal income tax
- Oregon state income tax
- FICA taxes (Social Security and Medicare)
- Employee deductions (retirement contributions, insurance, etc.)
- Employer withholdings
The result is an accurate estimate of take-home pay for each pay period.
Key Paycheck Formula
Here’s the general formula used in paycheck calculations:
Net Pay = Gross Pay – (Federal Tax + State Tax + FICA + Other Deductions)
Where:
- Gross Pay = (Hourly Rate × Hours Worked) or (Annual Salary ÷ Pay Periods)
- Federal Tax = Based on IRS tax brackets and filing status
- Oregon State Tax = Based on Oregon’s progressive tax rates
- FICA = 6.2% (Social Security) + 1.45% (Medicare) = 7.65% total
- Other Deductions = Retirement (401k), health insurance, union dues, etc.
Oregon State Tax Rates (2025)
Oregon uses a progressive state income tax system with the following brackets:
- 4.75% on income up to $4,050
- 6.75% on income from $4,051 to $10,200
- 8.75% on income from $10,201 to $125,000

This makes Oregon one of the higher-tax states in the U.S., so paycheck calculators are especially valuable for employees to estimate net income accurately.
