How to Plan for Profit as a Melbourne Small Business Owner

The Melbourne Cost Base Problem

Melbourne is an expensive city to run a business in. Commercial rent has increased significantly since 2022. Award wages go up each July. The Superannuation Guarantee rate has been climbing toward 12% since 2022. WorkCover premiums for trades businesses are among the highest industry classifications in Victoria. The ATO's small business benchmarks for Melbourne industries sit at higher absolute cost levels than regional comparisons.

The result: many Melbourne small businesses are generating $500k, $800k, or $1.2M in revenue but wondering where the money is. The business feels busy and successful. The bank account doesn't reflect it.

Profit doesn't happen accidentally. It requires deliberate planning — and it starts with understanding your numbers.

Step 1 — Know Your Gross Margin

Gross margin is revenue minus direct costs (the costs that go directly into delivering your service or product). For a Melbourne trades business, direct costs include materials, subcontractors, and direct labour. For a consultant, it might be just direct labour.

Gross margin formula: (Revenue − Cost of Sales) ÷ Revenue × 100

A Melbourne plumber billing $800k with $420k in materials and subcontractors has a gross margin of ($800k − $420k) ÷ $800k = 47.5%.

Gross margin is the foundation. If it's low, there's no amount of overhead cutting that fixes the business. If it's healthy, you have room to run the business and build profit.

Step 2 — Calculate Your Break-Even Revenue

Break-even is the revenue you need to cover all costs — direct and overhead — with zero profit.

Break-even formula: Fixed Costs ÷ Gross Margin %

Example: a Melbourne consulting firm with $20,000/month in fixed overhead and a 65% gross margin has a break-even of $20,000 ÷ 0.65 = $30,769/month. Any revenue above that is profit.

Once you know your break-even, you know the minimum you have to hit each month just to cover costs. And you know exactly how much more you need to reach your profit target.

Step 3 — Set a Profit Target and Reverse-Engineer It

Rather than hoping profit appears at year end, set a deliberate target and work backwards to find the revenue required.

Example: you want $120,000 net profit this year (roughly $10,000/month after all costs and owner drawings). Your fixed overhead is $25,000/month. Your gross margin is 45%.

• Required contribution to cover fixed costs and profit: $25,000 + $10,000 = $35,000/month
• Revenue required: $35,000 ÷ 0.45 = $77,778/month

That's your target. You now know whether your current pipeline and capacity can hit it — and if not, where the gap is (more revenue, better margin, or lower overhead).

Step 4 — Review Your Pricing

Melbourne's cost base has increased substantially in the past three years. If you haven't reviewed your pricing since 2022, you're almost certainly operating on compressed margins.

Things to check:

• Labour rate — your charge-out rate must cover the employee's wages, oncosts (super, WorkCover, leave loading), and a margin. The total employment cost for a Melbourne tradesperson is typically 25–35% above the base wage.
• Materials margin — are you charging a margin on materials? If you're buying at trade price and passing through at cost, you're absorbing the administration cost of purchasing and invoicing for nothing.
• Fixed-price jobs — are your fixed-price quotes still based on current material costs? A quote from 18 months ago with a fixed materials allowance may now be a loss-making job.

Step 5 — Build a Quarterly Financial Rhythm

Profit planning isn't a one-time exercise. It requires a quarterly review cadence:

• Monthly: Review your P&L against budget. Are gross margins holding? Is any expense line trending the wrong way?
• Quarterly: Review break-even and profit target against actual results. Adjust pricing, capacity, or overhead as needed.
• Annually: Set the following year's revenue and profit targets based on updated cost structures. Review all fixed contracts and supplier prices.

This rhythm only works if your Xero file is current and accurate. A P&L from a Xero file with months of unreconciled transactions is meaningless. Clean books are the foundation.
