How to Calculate Investment Property Returns (Step-by-Step)

  1. Enter property details – purchase price, upfront costs (stamp duty, legal).
  2. Loan structure: Interest-only loans maximise cash flow in early years; P&I builds equity.
  3. Estimate rental income & outgoings: Include council rates, property management, repairs, vacancy.
  4. Depreciation & tax: ATO allows capital works deduction (2.5% p.a. for residential) and plant write-offs. Use our field to reflect annual deduction.
  5. Analyse after-tax cash flow & ROI – Negative gearing provides tax refunds that improve net holding cost.
  6. CGT projection: Based on growth rate and marginal tax rate, we estimate taxable gain after 50% discount.

🏦 Using Equity to Buy Investment Property: Borrowing Power Calculator Logic

Many investors unlock equity from their home. Our tool factors total cash invested (deposit + costs). If you're using equity, the "Initial Equity / Deposit" represents the cash/equity contributed. The investment property borrowing calculator principle: LVR = (loan amount ÷ property value) × 100. Aim to keep LVR under 80% to avoid LMI. In 2026, lenders are cautious; positive cash flow improves borrowing capacity.

📉 Capital Gains Tax on Investment Property Calculator — How it Works

The CGT estimate assumes a 5-year hold with annual growth, 50% discount, and your current marginal rate. Formula: (Sale price − cost base) × 50% × marginal tax rate. It’s a guide; always consult a tax accountant. Use this cgt calculator investment property insight to forecast exit strategies.

Exclusive 2026 Update: ATO depreciation changes — new asset write-off thresholds for plant & equipment (e.g., appliances, carpets) effective 2026. Our depreciation field lets you input tailored annual deduction. For new builds, capital works deduction can reach $9,000+ yearly.

Investment Property Cash Flow & ROI Example

Consider a $780,000 apartment in Sydney’s west with $650 weekly rent, 3% vacancy, and $5,500 expenses. Using our tool, an investor on 37% marginal tax with $8,500 depreciation sees after-tax cash flow improve from -$2,800 to +$1,950 annually. That’s the power of negative gearing + depreciation. The cash flow calculator investment property above replicates real-world scenarios.

💡 Top Tips for Maximising ROI in 2026

Frequently Asked Questions — Investment Property Australia

What is a good ROI for an investment property in Australia?
Most investors target a cash-on-cash ROI of 4–8% after tax. High-growth areas may have lower yields but higher capital gains. Use our calculator to compare.
How to calculate capital gains tax on investment property with 50% discount?
Subtract cost base from sale price, apply 50% discount if held >12 months, then multiply by your marginal tax rate. Our CGT estimate provides a 5-year projection.
Can I claim depreciation on an established investment property?
Yes, if constructed after 1987, capital works deduction applies. Plant & equipment (original) may be depreciated based on remaining value. A depreciation schedule is essential.
Is negative gearing still worth it in 2026?
Absolutely. With moderate rental yields and interest deductibility, negative gearing reduces taxable income, improving net cash flow. The calculator above shows tax benefit value.
What’s the difference between P&I and IO for investment loans?
Interest-only (IO) loans minimise repayments and maximise cash flow, ideal for investors focusing on capital growth. Principal & Interest (P&I) builds equity faster but reduces short-term cash flow.
How do I estimate stamp duty for investment property?
Stamp duty varies by state (e.g., VIC ~5.5%, NSW ~4%). We included an upfront costs field; adjust based on your state’s rate and legal fees.
Does this calculator consider SMSF property investment?
Yes, SMSF investors can use the same cash flow logic. However, SMSF tax rate is 15% (or 0% in pension phase) — you can select a custom tax rate if needed, or use marginal rate as proxy.
