Building and Home Renovation Calculators for Australia
Plan building and renovation work in Australian dollars and metric units. The tools currently estimate deck materials, epoxy flooring costs, and concrete for fence posts. Inputs stay visible so you can check square-metre quantities, compare supplier prices, and understand what is or is not included before asking a tradie for a written quote.

Available tools
Only complete, working calculators are listed here. Planned tools stay off the page until their calculations, explanations, examples, and source notes are ready.
Deck Material Calculator
Estimate decking boards, joists, rim boards, and fasteners with metric or imperial inputs and an adjustable waste allowance.
Open calculatorDeck Post Concrete Calculator
Calculate concrete for deck piers and wider footing pads using metric dimensions.
Open calculatorEpoxy Flooring Cost Calculator
Estimate epoxy flooring costs in AUD per square metre, covering slab condition and coating system.
Open calculatorFence Post Concrete Calculator
Work out how much concrete you need per fence post hole in millimetres, including bag count.
Open calculatorHow localized estimates work
What changes by location
Australian pages start with AUD, metric terminology, and locally familiar product examples. The advanced epoxy estimate can apply a state or territory adjustment derived from published capital-city construction multipliers.
What does not change
Area, volume, and material quantities come from the dimensions and product details you enter. A postcode does not change those quantities.
What the estimate excludes
A tradie's written quote will usually add GST at the standard rate, plus disposal, delivery, or remote-area surcharges — Buildmator's planning range doesn't attempt to estimate any of those. Use the calculator to check the materials-and-labour range a quote is built on, not the final invoice.
Data coverage and limitations
A postcode helps identify the state or territory; it does not provide suburb-level pricing. Remote delivery and travel charges require a local quote.
Formulas, standards, and local rules
The underlying geometry stays the same unless a verified product rule, unit convention, or country-specific requirement genuinely changes the calculation. Country selection adjusts the calculator's units, terminology, product defaults, and supported cost data. It does not verify structural design, permits, or compliance with your local building regulations.

How estimates are built
01 · Project quantities
Area, volume, or bag count calculated from the dimensions and product details you enter.
02 · Rates, when relevant
Cost calculators use your material and labour rates, or a clearly labelled researched range.
03 · Regional adjustment
Advanced cost estimates use the most specific published location data available, with a national fallback.
04 · Project conditions
Supported cost tools account for preparation, removal, finish, and other choices that affect price.
Quantity calculators return material amounts from the inputs you provide. Cost calculators show a range because products, labour, and site conditions vary. When a location adjustment is used, the result identifies whether it came from metro, regional, or national data.
Measurement and pricing notes
Flooring area starts in square metres, and post-hole dimensions use millimetres or centimetres. Concrete bag sizes and yields vary, so use the figure on the product you will buy. Remote delivery or travel charges are not inferred from your postcode and need to be added separately.

I check each calculator with hand-worked examples and edge cases, then compare the results with the formulas and cited sources. I test location adjustments separately so a location field never changes a quantity that should depend only on your measurements.

Where to go next
Open a calculator above for a national planning range in minutes, or use the advanced flow and enter your state/territory and postcode for a location-adjusted estimate. If you're planning a project in another country, switch region below — each region keeps its own currency, units, and pricing data.
