Premium Google Sheets spreadsheet

Property Investment Spreadsheet (Australia)

Australian property investment spreadsheet with negative gearing, CGT, land tax, depreciation, and cash flow modelling in one Google Sheets template.

Two types of depreciation

Division 43 + Division 40

The ATO allows deductions for both building structure and plant & equipment

A quantity surveyor's depreciation schedule typically identifies significant deductions, particularly for properties built after 1985. This spreadsheet models both categories automatically.

Why a spreadsheet?

Tax calculations are deterministic: a specific income, property value, and state produce a specific tax outcome. A spreadsheet applies the exact published rates and lets you model scenarios with your own numbers, saving you from building complex 30-year cash flow formulas from scratch.

The free calculators on this site handle individual calculations — negative gearing, CGT, land tax, rental yield. The spreadsheet integrates them into one model so that related figures stay connected:

  • After-tax weekly holding cost (combining rental income, loan repayments, tax savings, and expenses)
  • Projected cash flow over 5, 10, or 30 years with adjustable growth assumptions
  • Interest rate sensitivity — adjust the rate and see the effect on every linked figure
  • Land tax comparison across states for the same property value
  • Hold-or-sell analysis with estimated CGT on disposal

Change one input and every downstream number updates.

Common use cases

  • Estimating the after-tax weekly holding cost of a property before purchasing
  • Comparing the land tax impact of buying in different states
  • Modelling whether to hold or sell a property, including estimated CGT on disposal
  • Projecting cash flow over multiple years with adjustable growth and interest rate assumptions
  • Preparing a rental property summary before meeting with an accountant

Included calculations

This spreadsheet integrates negative gearing, CGT, land tax, depreciation, rental yield, and cash flow into one model:

  1. Negative gearing tax savings (using current marginal tax rates)
  2. Capital gains tax estimates (with 50% discount and cost base adjustments)
  3. State land tax (all Australian states and territories)
  4. Depreciation (Division 40 plant and equipment + Division 43 capital works)
  5. Net rental yield (with 18+ expense categories)
  6. Multi-year cash flow projections (with capital growth and interest rate modelling)

The spreadsheet is delivered as a Google Sheet, accessible on any device.

What you get

All tiers include:

  • Ready-to-use Google Sheets template — make a copy and start entering your numbers in minutes
  • All formulas built in — no manual calculations
  • 2025–26 ATO tax rates, Medicare levy, and LITO
  • Getting-started guide with step-by-step instructions and worked examples
  • Clear cell formatting showing which cells to edit and which are calculated
  • Sources tab linking every rate and threshold to its official ATO or state government source

Australian tax rules only

Every rate and threshold is sourced from the ATO and state revenue offices. This is not a US template adapted for Australia — all formulas are built on Australian tax legislation.

The progressive tax brackets, the LITO phaseout, the Medicare levy, and the state-specific land tax thresholds are modelled on the published rates for the current financial year.

What’s NOT included in the free calculator

The free web calculators on this site handle individual calculations one at a time. The spreadsheet adds the features that serious property investors need:

  • Multi-year projections (10-30 years) — see how your cash flow changes as rent rises, loans amortise, and depreciation declines
  • Multi-property portfolio modelling (up to 5 properties) — track how each purchase affects your marginal tax rate and total out-of-pocket cost
  • Hold-vs-sell scenario comparison — model your CGT at different exit years alongside continued holding costs
  • Data persistence and customisation — save your numbers, adjust assumptions, and revisit scenarios any time
  • Shareable with your accountant — send a link instead of explaining your numbers from memory

Why choose this spreadsheet?

Similar property investment Excel tools from other providers cost $99-$199 — and they’re password-locked, Windows-only, and cannot be customised. Our Pro tier gives you comparable analysis for $24.99 in Google Sheets that works everywhere and is fully editable.

Frequently asked questions

Does the spreadsheet include a rent vs buy comparison?
Yes. The Pro and Complete tiers include a dedicated Rent vs Buy tab that compares renting while investing (rentvesting) against buying the same property as your home. It shows your crossover point (when escalating rent exceeds the mortgage), year-by-year cost and net wealth position for both scenarios, and the tax saving from negative gearing. The Complete tier also includes an ETF alternative comparison column so you can model investing the cost difference in shares instead of property.
What format is the spreadsheet?
Google Sheets. You'll receive a link to make your own copy. It works on any device — desktop, tablet, or phone — with no software to install. All formulas are included and update automatically as you enter your numbers.
Do I need to install anything?
No. Google Sheets runs entirely in your browser. You just need a free Google account. There is nothing to download or install.
Can I use it on my phone?
Yes. Google Sheets has a free mobile app for both iOS and Android, and the spreadsheet also works in mobile browsers. You can check your numbers on the go.
Are the tax rates current?
Yes. The spreadsheet uses 2025–26 ATO income tax brackets (including Stage 3 tax cuts), current land tax rates for all states and territories, and current Division 40 and 43 depreciation rules. All rates are verified against official ATO and state government sources.
Can I update the rates myself?
Yes. All rates are clearly labelled in a dedicated 'Rates' tab. You can update them yourself when new rates are announced. Complete tier customers receive lifetime updates — we update the rates for you each financial year.
How is this different from the free calculators on this site?
The free web calculators handle one calculation at a time. The spreadsheet integrates everything — negative gearing, CGT projections, land tax (all states), depreciation schedules, and multi-year cash flow — in one connected model. Change a rental income assumption and every downstream calculation updates automatically. It also saves your data so you can revisit and compare scenarios.
How does the hold vs sell analysis work?
Enter your current property details and a potential sale price. The Pro and Complete tiers calculate your estimated CGT (including the 50% discount for properties held over 12 months), compare the after-tax proceeds of selling vs the projected returns of continuing to hold, and show you the break-even point. This helps you make an informed decision when you're weighing up whether to keep or sell.
Do I need Excel?
No. The spreadsheet is built for Google Sheets, which is free. You do not need Microsoft Excel, though you can download it as an Excel file if you prefer (some formatting may differ).
Is this financial advice?
No. The spreadsheet provides general information only. It uses publicly available ATO rates and formulas to help you estimate your property investment position. It is not personal financial, tax, or investment advice. We recommend speaking with a registered tax agent or qualified financial adviser for advice specific to your situation.
What if the formulas are wrong?
If the spreadsheet has a major defect — broken formulas or incorrect calculations — you are entitled to a refund under Australian Consumer Law. We test all formulas against official ATO calculators and state revenue office tools. If you spot a discrepancy, let us know and we'll investigate and fix it.
How do Complete tier updates work?
When new ATO rates are announced (usually around May–June each year), we update the master spreadsheet. Complete tier customers receive an email with a link to the updated version. Your existing data stays in your copy — you just transfer your numbers to the new sheet.
Can I get a refund?
Yes, if the spreadsheet has a major defect (broken formulas, incorrect calculations). We do not offer refunds for change of mind, as the product is a digital download that cannot be returned. This is consistent with Australian Consumer Law for digital products.
