Coach's Corner
Don't Quit on Monday
Keep your day job until your side hustle consistently covers 75%+ of your expenses for 3+ months. Consistency proves the business, not one good month.
Budget for Self-Employment Costs
Going independent adds $500-1,500/mo in costs you don't see as an employee: health insurance, self-employment tax (15.3%), retirement contributions, software, and accounting.
Pay Yourself First
Transfer savings the day you get paid, not at the end of the month. You can't spend what you've already saved. This single habit separates savers from spenders.

The Runway That Makes It Safe
Turning a side hustle into your main gig is mostly about buying yourself time. The question isn't "am I ready?" — it's "how many months can I cover my expenses while the business ramps?" This calculator turns your expenses, current side-hustle income, and desired runway into a savings target.
What to Include
Base your target on your real monthly expenses, then subtract the income your side hustle already reliably brings in. The gap is what your savings need to cover each month. A longer runway lowers the pressure to take bad clients or give up too early.
A Sensible Target
Many people aim for 9–18 months of the expense gap before quitting, plus a separate emergency fund. That's usually enough to survive a slow start and reach the point where the business covers your costs. Adjust the timeline to see how the target changes.
