Open both calculators and enter your real bookings. Use the same average ticket and weekly client count in each. Compare monthly take-home, effective hourly, and guaranteed weekly pay (commission) vs. break-even cushion (booth rent). The interesting number is rarely the headline pay — it's the gap between best week and worst week.
A commission offer at $18/hr + 35% with 12 weekly bookings at $100 typically nets $5,000–$6,000/month before tax. A solo booth at $250/week rent with the same bookings nets $4,800–$5,500 after rent, supplies, and a 25% tax set-aside — but the solo number scales linearly with bookings while commission has a softer ceiling.
