Earnings, schedules, and realistic scenarios

Income Planning Formula:

$Monthly\ Income = Hourly\ Rate \times Hours\ Worked$

At rates of $25–45/hr, even modest weekly hours add up.

• 10 hrs/week → $1,000–$1,800/month
• 20 hrs/week → $2,000–$3,600/month
• 30 hrs/week → $3,000–$5,400/month

Below is a simple helper script to forecast earnings across scenarios.

# Quick earnings calculator
rates = [25, 35, 45]
hours_per_week_options = [10, 20, 30]
weeks_per_month = 4
for r in rates:
    for h in hours_per_week_options:
        monthly = r * h * weeks_per_month
        print(f"Rate ${r}/hr, {h} hrs/week => ${monthly}/month")
