What Is the ADP Oregon Paycheck Calculator?
The ADP Oregon Paycheck Calculator is a financial tool that estimates the amount of money an employee takes home after all mandatory and optional deductions are applied.
It factors in:
- Gross income
- Federal income tax
- Oregon state income tax
- FICA taxes (Social Security and Medicare)
- Pre-tax deductions (health insurance, 401(k), etc.)
- Post-tax deductions (union dues, garnishments, etc.)
By entering a few details like gross pay, pay frequency, and filing status, users can get an accurate estimate of their net pay in seconds.
How the ADP Oregon Paycheck Calculator Works
The calculator uses formulas based on Oregon’s state tax rates and federal withholding guidelines established by the IRS. It applies these to your input data to determine your net (take-home) pay.
1. Gross Pay Formula
Gross pay is the total income earned before deductions.
Gross Pay = Hourly Rate × Hours Worked
If you’re salaried:
Gross Pay = Annual Salary ÷ Number of Pay Periods
2. Federal Income Tax Formula
Federal tax is calculated using IRS tax brackets.
Federal Tax = (Taxable Income × Applicable Rate) – Adjustments
These rates vary based on your filing status (single, married, head of household).
3. FICA Taxes (Social Security and Medicare)
Social Security Tax = Gross Pay × 6.2%
Medicare Tax = Gross Pay × 1.45%
If your earnings exceed $200,000 annually, an additional 0.9% Medicare surtax applies.
4. Oregon State Income Tax Formula
Oregon has a progressive tax system with multiple brackets.
Oregon Tax = (Taxable Income × State Rate) – Standard Deductions
The rates (as of 2025) are approximately:
- 4.75% on the first $4,050
- 6.75% on $4,051 to $10,200
- 8.75% on $10,201 to $125,000
- 9.9% on income over $125,000
5. Other Deductions
These can include:
- Pre-tax deductions (retirement, insurance, HSA)
- Post-tax deductions (wage garnishments, charity contributions)
Net Pay = Gross Pay – (Federal Tax + State Tax + FICA + Deductions)

Example Calculations
Example 1: Hourly Employee
- Hourly rate: $25/hour
- Hours worked: 40
- Filing: Single
- Pay frequency: Bi-weekly
Gross Pay = 25 × 40 = $1,000
FICA = 7.65% of 1000 = $76.50
Federal Tax ≈ $100
Oregon Tax ≈ $65
Net Pay = 1000 – (76.50 + 100 + 65) = $758.50
✅ Result: Take-home pay = $758.50
Example 2: Salaried Employee
- Annual Salary: $60,000
- Filing: Married
- Pay frequency: Bi-weekly
Gross Pay = 60,000 ÷ 26 = $2,307.69
FICA = 7.65% of 2,307.69 = $176.49
Federal Tax ≈ $230
Oregon Tax ≈ $150
Net Pay = 2,307.69 – (176.49 + 230 + 150) = $1,751.20
✅ Result: Take-home pay = $1,751.20 per paycheck

Why Oregon’s Tax System Matters
Unlike some U.S. states, Oregon does not have a state sales tax, but it does have relatively high income tax rates. That means your take-home pay can vary significantly depending on your income bracket and deductions.
Other taxes and contributions that may apply in Oregon include:
- Paid Leave Oregon (employer and employee contribution)
- Transit taxes (TriMet or Lane Transit District)
- Local jurisdiction fees (if applicable)
Understanding these helps ensure that your paycheck calculations remain accurate throughout the year.
