How To Use The Concrete Cost Per m³ Calculator

This concrete cost per m³ calculator shows the price you really pay for each cubic metre, which can be a long way from the headline rate. It is built around supplier fees, so it is most useful for small and medium orders.

  1. Enter your order. Type the cubic metres, or enter a slab size and let the tool work it out.
  2. Enter your rate. The box starts at A$380 per m³, the typical rate from What's The Damage. Use your own quote if you have one.
  3. Choose a fee schedule. Pick a published example, then type over the numbers with your own supplier's fees.
  4. Add any extras. Open Cartage, Waiting And Extras for long distances, waiting time, special mixes or a pump.
  5. Compare a second supplier. This is optional. It shows which quote is cheaper once delivered.
  6. Press Calculate. You get the delivered cost per m³, a chart by order size, and a comparison with bags.

Need the volume first? Use the Concrete Volume Calculator, or the Concrete Quantity Estimator for a whole job. For the price of a finished slab, including labour and base, see the Concrete Slab Price Estimator.

Quoted Rate Or True Cost Per m³?

A rate per cubic metre is only the start. It is the price of the concrete at the plant or chute, and suppliers often add other charges. The figure that matters is the total you pay, divided by the concrete you get.

True cost per m³ = Total paid ÷ Cubic metres delivered

On a full truck, the two numbers are close. On a small load, they can be far apart. A A$380 rate can turn into more than A$600 per m³ on a 1 m³ order, because the short-load fee is spread over very little concrete.

This matters for two reasons. It helps you set a realistic budget, and it lets you compare suppliers fairly. A supplier with a lower rate and a higher short-load fee can end up costing more on a small job.

Published Concrete Prices Per m³ In Australia

Published prices vary widely, partly because they do not all measure the same thing. Suppliers rarely publish their list prices, so these are guides from cost websites.

SourceWhat It CoversPrice Per m³Date
What's The Damage25 MPa delivered, supply only, nationalA$300 to A$480, typically A$380November 2026
What's The Damage25 MPa supply only, Melbourne, with GSTA$315 to A$505, typically A$400November 2026
Yellow PagesStandard mixed concrete, nationalA$400 to A$450April 2026
New Life In Australia25 MPa, before delivery and pumpA$210 to A$250October 2026

The New Life In Australia figures are much lower than the others. Those prices are before delivery and pump hire, its page calls them indicative, and it says exact list prices are not published. Treat that row with care, and do not budget from it alone. The tool starts with the What's The Damage figure, because it is the most recently verified, and it is stated as a delivered, supply-only price.

Whichever figure you start with, a phone quote is the only one that counts. Prices depend on your suburb, the mix, the plant and the day.

Concrete Cost Per m³ By Strength

Stronger concrete uses more cement, so it costs more. Two published guides show that pattern, though their levels differ.

StrengthYellow PagesNew Life In AustraliaCommon Use Listed
20 MPaA$400A$180 to A$220Footpaths, garden edging
25 MPaA$410A$210 to A$250House slabs, driveways
32 MPaA$430A$250 to A$300Heavy-duty driveways, structural slabs
40 MPaA$450A$300 to A$380Structural and commercial work

Yellow Pages shows a steady step of A$10 to A$20 per m³ between grades. New Life In Australia shows bigger steps. Either way, going up one grade usually costs less than a single short-load fee.

The strength is not a place to save. It comes from your plans, your council or an engineer. For the meaning of N20, N25 and N32, read our guide to concrete grades.

Concrete Cost Per m³ By City

Only one of our sources breaks the price down by city. These are indicative figures from New Life In Australia, before delivery and pump hire. They are useful for comparing one city with another, but they sit below the national ranges above. The page also says rural areas are commonly quoted 15 to 25% higher.

City20 MPa32 MPa And AboveDelivery Radius
MelbourneA$170 to A$210A$250 to A$32040 km
SydneyA$185 to A$230A$270 to A$35050 km
BrisbaneA$180 to A$225A$260 to A$34045 km
PerthA$200 to A$280A$290 to A$38030 km

What's The Damage lists 25 MPa at A$315 to A$505 per m³ in Melbourne, including GST, which is well above the Melbourne row here. That is a good reason to get a real quote. Distance from the plant also matters, because supplier schedules charge extra cartage past a set distance.

How Order Size Changes The Cost Per m³

This is the biggest factor for small jobs. This table uses a A$380 rate with the Holcim Melbourne fees, a 4 m³ short-load limit and A$3.50 in levies. The variable surcharge is left out, and GST is not added.

Order SizeShort FeeTotalCost Per m³
1 m³A$240A$624A$624
2 m³A$160A$927A$464
3 m³A$80A$1,231A$410
4 m³A$0A$1,534A$384
6 m³A$0A$2,301A$384
7 m³ On 6 m³ TrucksA$240A$2,925A$418

Notice two things. First, the cost drops quickly up to the short-load limit, then stays flat. Second, it rises again at 7 m³, because the second truck carries only 1 m³. A small extra amount can bring the short-load fee back. Sometimes it is cheaper to trim or top up the order, or to ask about a larger truck. iSeekPlant lists standard agitators at 6 to 8 m³.

A Real Example

Yellow Pages reports that Eureka Concrete in Ballarat quotes A$407 for 1 m³ of 20 MPa, A$583 for 2 m³ and A$795 for 3 m³. By our arithmetic, that is about A$407, A$292 and A$265 per m³. The same pattern shows up, with the price per m³ falling as the load grows.

Fees That Change The Cost Per m³

Large suppliers publish their service fees by region. Here are four current examples. All exclude GST, and each applies only to its own region. These are the schedules loaded into the calculator.

Late Cancellation, Small PourA$525A$400A$500A$750
Effective1 May 20261 May 20261 July 20261 July 2026

The sources are Holcim Melbourne, Holcim Perth, Holcim South East Queensland and Boral Tasmania. The cancellation row is for the smallest pour size in each schedule, and each has its own notice rules.

Short-Load Fees

The fee applies to the part of the truck you are not using. For example, a 2.5 m³ load with a 4 m³ limit is 1.5 m³ short. At A$80, that adds A$120.

Levies And Surcharges

Holcim lists an environment levy in each region, plus a toll levy in Melbourne. The tool includes those fixed amounts. Holcim also lists a Production and Transport Surcharge that is updated fortnightly, with no fixed figure, so the examples leave it out. Ask your supplier for the current amount and add it to the Levies box. Boral's Tasmanian schedule lists its surcharge at A$13.44 per m³, subject to change. Yellow Pages separately reports a much lower Boral transport charge of A$1.34 per m³ from July 2025, so check the current figure.

Cartage And Waiting Time

Sites far from a plant pay extra per km and per m³. Waiting time starts once the free unloading time is up. On a job with a slow pump or a small crew, those minutes add up.

Mix Extras And After-Hours Charges

A special mix or a weekend pour can add a lot per cubic metre. Use the Mix Extras box in the calculator for these. The Perth Saturday figure is our likely reading of a table that was hard to read, so check it.

ExtraHolcim MelbourneHolcim PerthHolcim South East Qld
10 mm AggregateA$26A$12A$10
Slump Above 80 mm, Per 20 mmA$4.20A$8A$5
Oxides And FibresA$10.50A$8A$15
Saturday 12 pm To 4 pmA$42A$55 (likely reading)A$45

Holcim's Melbourne schedule also lists A$6 per m³ for Saturday from 6 am to 12 pm, so an early start can cost much less than an afternoon pour. Boral Tasmania charges nothing extra on Saturday mornings, and A$60 per m³ from 12 pm. Holcim says water should not be added on site to increase slump, so ask for the slump you need when you order. See its ordering tips for more.

Core fill and block work often use 10 mm aggregate. The Concrete Block Wall Calculator covers those quantities.

Ready-Mix Or Bags: Cost Per m³

Bagged concrete costs far more per cubic metre. The Bunnings listing for Dingo MaxPRO shows a 20 kg bag at A$14.44, and says 108 bags make one cubic metre. That comes to about A$1,560 per m³. New Life In Australia gives a similar A$1,000 to A$1,800 per m³.

So even a heavily charged 1 m³ short load, at about A$624, is less than half the price of bags. So why buy bags at all? They can still suit a very small job, because the total is what counts:

  • A post or two needs only a few bags, and a truck would be overkill.
  • You can buy only what you need, and work at your own pace.
  • There is no booking, and no truck access to arrange.

Each bag also has to be carried, mixed and placed, and that effort rises quickly. Our Concrete Bag Calculator helps with the count. For a mix made from cement, sand and gravel, use the Concrete Mix Calculator.

From Cost Per m³ To Cost Per m²

Ready-mix is sold by the cubic metre, while slabs are often priced by the square metre. To change one into the other, multiply the cost per m³ by the thickness in metres.

Concrete cost per m² = Cost per m³ × Thickness (mm) ÷ 1000

So A$400 per m³ at 100 mm is A$40 per m² for the concrete alone. At 150 mm, it is A$60 per m². That is well below a laid slab price, because a laid price also covers the base, steel, forms, labour and finishing. Comparing the two directly is a common mistake. For a full build-up, use the Concrete Slab Price Estimator.

What To Ask When You Ring For A Price

A quick phone call gets you a much better number if you ask the right questions.

  • What is the delivered price per m³ for my grade, slump and aggregate size?
  • What is the short-load limit, and what is the fee?
  • What levies or surcharges apply this month?
  • How far is my site from the plant, and is extra cartage charged?
  • How long is free unloading, and what does waiting cost?
  • What notice do you need if I cancel or move the pour?
  • Does the price include GST?

Enter the answers in the calculator, and you will have a true cost per m³ for each supplier. Holcim suggests ordering at least a week before delivery, and lead times vary by region.

Concrete Cost Per m³ Formulas

The calculator adds each charge, then divides by the order.

Concrete = Order × Quoted rate
Last load = Order − Full loads × Truck load
Short-load fee = (Limit − Last load) × Fee, if the last load is under the limit
Levies = Order × Levy per m³
Cartage = Order × Extra km × Rate per km per m³
Waiting = Extra minutes × Rate per minute
Cost per m³ = Total ÷ Order

For a slab, the order is length × width × thickness, plus your waste allowance, rounded up to 0.1 m³. The tool assumes full loads first, with only the last load short. Your supplier may split it differently. Dollar figures are rounded to the nearest A$1.

Concrete Cost Per m³ Worked Examples

These examples use the calculator's own output, with a A$380 rate and Holcim Melbourne fees unless stated. GST is not added. They only show how the maths works.

2.5 m³ Order

The concrete is A$950. The load is 1.5 m³ short of 4 m³, which adds A$120, and levies add about A$9. The total is A$1,079, or A$432 per m³. That is A$52 more per m³ than the quoted rate.

4 m³ Order

The short-load fee disappears. The total is A$1,534, or A$384 per m³.

7 m³ On 6 m³ Trucks

The second truck carries just 1 m³, so 3 m³ is charged as short, at A$240. The total is A$2,925, or A$418 per m³. It is worth asking whether one larger truck could take the full order.

Slab, 6 m By 5 m At 100 mm

With 10% waste, the order is 3.3 m³. That is 0.7 m³ short, which adds A$56. The total is A$1,322, or A$400 per m³.

5 m³ With Extras

A site 8 km past the free zone adds A$114. Fifteen minutes of waiting adds A$44. A 10 mm mix at A$26 per m³ adds A$130. With levies, the total is A$2,206, or A$441 per m³.

Two Quotes For 2 m³

Supplier A quotes A$370, with a A$90 short-load fee and A$2.50 in levies. Supplier B quotes A$395, with a A$50 fee and A$2 in levies, and both have a 4 m³ limit. Supplier A comes to A$925, or A$463 per m³. Supplier B comes to A$894, or A$447 per m³. The higher quoted rate is A$31 cheaper overall.

Ways To Lower Your Concrete Cost Per m³

  • Reach the short-load limit. Ask what the limit is, and see if another small job can use the same load.
  • Team up with a neighbour. Some jobs can share a truck if the supplier allows it and access works.
  • Avoid a tiny last load. Check your total against the truck size before you confirm.
  • Pour during normal hours. Saturday afternoon charges can add A$40 or more per m³.
  • Be ready for the truck. Have the crew, the forms and the pump set before it arrives, so that you avoid waiting fees.
  • Choose the closest plant. Extra cartage is charged per km and per m³.
  • Ask for all fees in writing. Get a full delivered price, not just a rate.
  • Measure carefully. Holcim says to base the volume on site measurements, not drawings.

Common Mistakes

  • Comparing rates and not totals. The lowest rate is not always the lowest price.
  • Mixing prices with and without GST. Check each one.
  • Comparing per m³ and per m² prices. A price per m² usually includes labour.
  • Forgetting the cancellation rules. A late change can cost hundreds of dollars.
  • Cutting the grade to save money. Use the strength on your plans.

Wet concrete can burn skin and eyes, so wear gloves, long sleeves and eye protection. Cutting or grinding hardened concrete creates dust that can contain silica. Read Safe Work Australia's silica guidance first. Our How We Calculate Concrete page explains how we use these figures.

Concrete Cost Per m³ Calculator FAQs

How Much Does Concrete Cost Per m³ In Australia?

What's The Damage lists 25 MPa ready-mix at A$300 to A$480 per m³ delivered, typically A$380, in November 2026. Yellow Pages gives A$400 to A$450. Small orders can cost far more per m³ once fees are added.

How Much Is 1 m³ Of Concrete Delivered?

It depends on short-load fees. In one Yellow Pages example, a Ballarat supplier quotes A$407 for 1 m³ of 20 MPa. With A$380 concrete and Holcim Melbourne fees, 1 m³ comes to about A$624.

Why Is A Small Load Of Concrete So Expensive?

A truck still has to be sent, whatever it carries. So suppliers charge a short-load fee on the undelivered part. Four published schedules set the limit at 3 or 4 m³, with fees of A$50 to A$90 per m³ short.

What Is The Cheapest Order Size For Ready-Mix?

Usually a full load, or an order at or above the short-load limit. In our example with a 4 m³ limit, the cost per m³ falls from about A$624 at 1 m³ to about A$384 at 4 m³.

How Much More Is N32 Than N25?

Yellow Pages lists 32 MPa at about A$20 more per m³ than 25 MPa. New Life In Australia shows a gap of about A$40 to A$50. Get a price for your exact mix, as the grade comes from your plans.

Does Concrete Cost Include Delivery?

It varies. What's The Damage says its rate is delivered to the chute, while New Life In Australia gives prices before delivery. Always ask for a delivered price, including all levies.

Is It Cheaper To Buy Bags Or Ready-Mix?

Per m³, ready-mix is much cheaper. One 20 kg bag at A$14.44 and 108 bags per m³ comes to about A$1,560 per m³, against about A$624 for a 1 m³ short load in our example. Very small jobs can still suit bags.

How Many Bags Equal 1 m³ Of Concrete?

About 108 bags of 20 kg, according to the Bunnings listing for Dingo MaxPRO. Check the yield on your own bag.

What Is A Production And Transport Surcharge?

It is an extra charge per m³ that some suppliers add on top of the rate. Holcim says its surcharge is variable and updated fortnightly, so the tool leaves it out of its examples. Boral Tasmania lists A$13.44 per m³.

Do Concrete Prices Include GST?

Not always. The Holcim and Boral fee schedules exclude GST. The What's The Damage Melbourne page includes it. Bunnings shelf prices include it. Check each figure before you compare.

How Do I Compare Two Concrete Quotes?

Compare the delivered cost per m³, not the headline rate. Enter both rates and short-load terms in the calculator. A lower rate can end up dearer on a small order.
