Stop starting from blank workbooks
Build a first-pass feasibility without copying another spreadsheet and hoping the formulas still work.
Built for Australian developers

Designed for the teams behind Australian property development
Why teams switch
A cleaner way to work than another workbook.
A spreadsheet can help with one model. For screening sites repeatedly, Popurise keeps the deal logic structured and in one place.
Keep the deal logic visible
Structure land, costs, revenue, timing, debt and return metrics in one workflow.
Change assumptions without chaos
Test what moves the deal without chasing hardcoded cells through another workbook.
Move beyond one-off templates
Go from a quick screen to saved projects, clearer outputs and repeatable scenario review.
The old way vs Popurise
Every new site starts as another spreadsheet.
A feasibility built in Excel is fine on day one and fragile by version five. The formulas drift, the assumptions hide, and the file becomes the system of record. Popurise gives your team one place to screen the deal, compare the cases and see the numbers that decide what moves forward.

What a spreadsheet includes
Everything a feasibility spreadsheet tries to hold.
A development feasibility model has to carry all of this at once. Popurise structures the same inputs and outputs in software, so nothing hides in a cell and the outputs recalculate as you change assumptions.

Popurise structures these inputs and outputs in one workflow. Tax and GST are handled at a general level for Australian residential projects, not as formal tax advice.
In plain English
What a feasibility spreadsheet is, and the alternative.
The same job a workbook does, structured in software so it holds up across every site you screen.
In short
A property development feasibility spreadsheet is an Excel or Google Sheets model that tests whether a development site stacks up. It turns assumptions about land, acquisition costs, construction, professional fees, contingency, finance, timing and sales revenue into development profit, development margin, profit on cost, cash flow and IRR. Popurise is a property development feasibility spreadsheet alternative for Australian teams: it structures the same inputs and outputs in software, so you can screen sites repeatedly, save projects and compare scenarios without rebuilding a fragile workbook for every deal.

Excel is flexible, but fragile when deals, timing, debt and scenarios change. Popurise gives structure where repeated feasibility work becomes painful.
Start freeAn honest chooser
When a spreadsheet is still fine.
Popurise is not against Excel. Each tool has a job. Here is how we would pick between them.
For a highly custom one-off model
When you need bespoke logic for a single deal and you are comfortable maintaining the formulas yourself, a spreadsheet is still the flexible choice.
For a rough first-pass check
When you only need a quick read on whether a site is worth a second look, a free calculator gives you profit, margin and profit on cost in seconds.
Try the free calculatorFor repeatable feasibility
When you screen sites often and need saved projects, clearer assumptions, timing, debt, cash flow and outputs that are easier to review, Popurise is the cleaner way to work.

Assumptions
- Land purchase price
- $6.5M
- Acquisition costs (stamp duty, legals, DD)
- $0.55M
- Construction cost
- $34.0M
- Professional fees
- $2.6M
- Contingency (5% of construction)

- Marketing and selling costs

- Finance (debt ~60% LTC, ~18 months)
- $2.1M
- Gross realisation (GRV)

- Development timing
- ~30 months
In a spreadsheet
Contingency, finance and GST sit across different tabs, so a single edit can quietly break the profit line.
Where it goes wrong
A hardcoded cell over a formula, or a stale version emailed around, and the numbers no longer agree.
In Popurise
The same assumptions sit in one structured workflow, and the outputs recalculate as you change them.

Questions
Feasibility spreadsheets, answered.
What is a property development feasibility spreadsheet?
It is an Excel or Google Sheets model that tests whether a development site is financially viable. It takes assumptions about land, acquisition costs, construction, fees, contingency, finance, timing and sales revenue, and returns development profit, development margin, profit on cost, cash flow and IRR. Most teams build one per deal, then copy and adapt it for the next site.
What should a development feasibility spreadsheet include?
At a minimum: land price, acquisition costs and stamp duty, construction cost, professional fees, contingency and other project costs, timing and staging, debt and interest, sales revenue or GRV, cash flow, and the output metrics that decide the deal (development profit, development margin, profit on cost, IRR, peak debt and peak equity). Popurise structures these same inputs and outputs so nothing is buried in a cell.
Is Popurise a replacement for Excel?
For repeatable development feasibility, yes. Popurise gives you structured inputs, project timing, debt and interest, monthly cash flow, scenario comparison and shareable outputs without hand-building and maintaining a workbook. Excel stays useful for highly custom one-off work, and you can export to Excel or CSV when you need to hand numbers to someone who works there.
When should I use Excel instead of feasibility software?
Use a spreadsheet when you need a highly custom one-off model and you are comfortable maintaining the formulas. Use a quick calculator when you only need a rough first-pass check. Use Popurise when you need repeatable feasibility across many sites, saved projects, clearer assumptions, timing, debt, cash flow and outputs that are easier to review and share.
What is the difference between a feasibility spreadsheet and a feasibility calculator?
A calculator answers one question quickly, such as a single profit, margin or supportable land value for one set of inputs. A spreadsheet or feasibility software goes further: structured inputs, timing, debt, cash flow and scenario comparison. Use a calculator to screen, then take a site that deserves a proper look into the full workflow.
Can Popurise model timing, debt and cash flow?
Yes. Popurise models project timing and staging, a debt facility with interest and drawdown, and a monthly project cash flow, so you can see peak debt, peak equity and how returns move as the program changes. These are the parts a spreadsheet is slowest to keep up with.
Does Popurise work for Australian residential development?
Yes. Popurise is designed for Australian residential development (apartments, townhouses and medium-density sites) with acquisition costs, GST on sales, construction, finance and timing modelled the way Australian projects actually run.
Can I compare multiple development sites?
Yes. You can build scenarios within a project and keep every project saved in one workspace, so comparing sites and assumptions is a like-for-like comparison rather than a folder full of copied spreadsheets.
Is this financial advice?
No. Popurise and the preview on this page are modelling tools for testing development assumptions. Outputs are illustrative and depend entirely on the inputs you provide. They are not financial, investment, planning, tax or valuation advice.
