Did You Know?
How Does Prorated Salary Work?
Daily Rate Method
Annual Salary ÷ 260 = daily rate. Multiply by days worked. Example: $60,000 ÷ 260 × 130 = $30,000 for half a year. This is the most common method for salaried employees in the US.
Monthly Method
Annual Salary ÷ 12 × months worked. Starting July 1 = 6 months = 50% of salary. Some employers prefer this for simplicity when start dates align with month boundaries.
Tax & Deductions
Proration applies to gross pay. Taxes and benefits are calculated on the prorated amount. Your effective tax rate may be lower in a partial year due to progressive brackets.
First Paycheck Impact
If you start mid-pay-period, your first check covers only the days from your start date to the next payday. A biweekly employee starting on day 8 of a 14-day period receives ~43% of a full check.
