Investor is looking at a property asking $620,000 that is currently tenanted at $450 per week. Before they call the agent back, they need to know what the yield actually is after expenses -- not the headline gross figure.
Net yield = ((Annual rent − All annual costs) ÷ Property value) × 100. This is what you actually earn.
A property with 5% gross yield might only return 3–3.5% net after costs. Target 4%+ net in AU for positive cash flow (depending on leverage).
1 What this calculator does
Calculates gross rental yield and net rental yield from property value, weekly rent and annual expenses. Net yield accounts for council rates, insurance, property management fees and maintenance. Flags whether the property is likely positively or negatively geared.
2 Formula & professional reasoning
Annual rent = Weekly rent x 52
Gross yield (%) = Annual rent / Property value x 100
Net annual rent = Annual rent - Rates - Insurance - Management fee - Maintenance
Net yield (%) = Net annual rent / Property value x 100
Gross yield is the quick comparison metric -- but net yield is what actually flows through to the investor's pocket. For most Australian investment properties, the difference between gross and net yield is 1-2 percentage points. A property yielding 5% gross may yield only 3.5% net after expenses. Properties with gross yields above 5% and net yields above 4% are typically positively geared (income exceeds costs) when interest costs are favourable.
3 Worked examples
⚠️ Illustrative example only — not clinical or professional instruction.
Annual rent: $450 x 52 = $23,400 | Management fee: $23,400 x 0.085 = $1,989 | Total expenses: $2,200 + $1,800 + $1,989 + $3,000 = $8,989 | Net rent: $23,400 - $8,989 = $14,411 | Gross yield: $23,400 / $620,000 x 100 | Net yield: $14,411 / $620,000 x 100Annual rent: $21,840 | Management: $2,184 | Total costs: $7,884 | Net rent: $13,956 | Gross: $21,840 / $380,000 | Net: $13,956 / $380,000Residential net yield: ($31,200 - $25,000) / $800,000 = 0.78% | Commercial net yield: ($57,200 - $8,000) / $800,000 = 6.15%4 Sanity check
5 Common errors
| Error | Cause | Consequence | Fix |
|---|---|---|---|
| Using gross yield alone for investment decisions | Not accounting for expenses | Property appears profitable but is actually deeply negatively geared | Always calculate net yield. For investment decisions, also factor in mortgage interest cost to assess true cash flow and gearing position. |
| Using current market value instead of purchase price for yield calculation | Wanting to show current yield looks better as the property has grown | Misleads on actual investment return relative to what was paid | For historical performance assessment use purchase price. For current opportunity cost analysis (should I sell?) use current market value. Be clear which basis you are using. |
| Not including a vacancy allowance | Assuming the property is tenanted 52 weeks per year | Net yield overstated by 2-4% annually -- actual cash flow lower than projected | Apply a 2-4% vacancy rate to annual rent. Multiply annual rent by 0.97 (3% vacancy) before calculating net yield. |
| Underestimating maintenance costs | Using a low maintenance figure for new properties, then not updating when property ages | Cash flow significantly worse than modelled as the property ages and repairs increase | Use 1-2% of property value per year as a maintenance provision. A $600,000 property should budget $6,000-$12,000/yr for maintenance including periodic capital works. |
