javaCopyEditNet Pay = Gross Pay - (Federal Tax + State Tax + Social Security + Medicare + Pre-Tax Deductions) Example Calculation
Let’s say you earn $3,000 biweekly in Colorado, are single, and contribute $200 to a 401(k).
- Gross Pay: $3,000
- Federal Tax (approx.): $260
- Social Security (6.2%): $186
- Medicare (1.45%): $43.50
- State Tax (4.4%): $132
- 401(k) Deduction: $200
Net Pay = $3,000 – ($260 + $186 + $43.50 + $132 + $200) = $2,178.50
