Take-home estimate

Enter a deduction % — combined tax + benefits + retirement, whatever comes off the top.
From the book — Chapter 1 of The Money Math Workout. Annual pay = hourly × hours/week × weeks/year; divide back for the hourly behind a salary. Biweekly = annual ÷ 26, monthly = annual ÷ 12. Overtime pays the multiplier (usually 1.5×) on hours above the standard week. Take-home is a rough estimate — real deductions vary by state and situation.
