FAQ
Frequently asked questions
What is a break-even point?
The break-even point is when your total revenue equals your total costs (startup + ongoing). After this point, the business is generating profit. Most small businesses in Australia take 1-3 years to break even.
How much cash reserve should a new business have?
The Australian Small Business and Family Enterprise Ombudsman recommends 3-6 months of operating expenses as a cash buffer. For seasonal businesses, 6-12 months is safer.
What are common startup costs in Australia?
Common costs include ABN/business registration ($0-$500), business insurance ($1,000-5,000/yr), equipment, website, marketing, fit-out, legal advice, accounting setup, and initial inventory. The ABS reports average startup costs of $10,000-$50,000 for small businesses.
Do I need an ABN to start a business?
You need an ABN if your annual turnover is $75,000 or more (or you're running an enterprise). You must register for GST if turnover hits $75,000. ABN registration is free at abr.gov.au.
