How to Use This Concrete Calculator
Pick Your Project or Shape
There are two ways to use this calculator.
"What are you building?" mode is the faster option. Pick your project type: driveway, garage floor, foundation, deck piers, retaining wall, stairs, patio, or commercial slab. The calculator automatically sets the right mix strength (MPa), recommended thickness, and air-entrainment based on CSA A23.1 standards. You just enter the dimensions.
Advanced / Shape mode gives you full control. Choose your shape (slab, footing, column, wall, stairs, post hole), enter exact measurements, and adjust every variable manually. This is the mode contractors and estimators use when they need precise numbers for a bid.
Not sure which mode to use? Start with the project picker. It handles the defaults so you don't have to.
Enter Your Dimensions
Every calculation comes down to one thing: volume. The calculator multiplies your length x width x thickness (or depth, or height, depending on the shape) to get cubic metres. That's what you order.
Enter dimensions in metric (metres / millimetres) or imperial (feet / inches) using the toggle at the top. Canada uses metric for ready-mix ordering, but most field crews still measure in feet. Both work.
- Slabs and pads: Enter length and width in metres, thickness in millimetres. A standard residential driveway runs 125mm thick. A garage floor is typically 100mm.
- Footings: Depth matters most here. Your footing must sit below the frost line for your province. Alberta: 1.2 to 1.5m. Ontario: 1.2 to 1.5m. Saskatchewan: up to 1.8m. The calculator includes frost depth presets by province.
- Columns and piers: Enter the Sonotube diameter and depth. The calculator uses the circular cross-section formula automatically. Standard deck piers use a 200mm or 300mm tube.
- Walls: Length x height x thickness. Don't forget to subtract door and window openings from your total. The calculator works from the dimensions you enter.
- Stairs: Enter number of steps, rise (height per step), run (depth per step), and width. The NBC recommends 175mm rise and 280mm run for exterior stairs.
Select Your Province
Your province sets two things automatically: the 2026 ready-mix price default and the air-entrainment recommendation. Ready-mix prices vary significantly across Canada. Here's what the calculator defaults to in 2026:
- Alberta: $190/m³ (Edmonton Spring 2026 market rate)
- British Columbia: $235/m³ (Lower Mainland; interior BC runs higher at $230 to $270)
- Ontario: $195/m³ (provincial average; GTA runs toward the top of the range)
- Quebec: $190/m³
- Maritimes: $205 to $220/m³
- Northern Canada (NT, NU, YT): $360 to $550/m³ due to logistics
You can override the price with your actual supplier quote at any time. That number is the one that matters.
Choose Your Mix Strength (MPa)
This is where Canadian concrete differs from American specs. Canada uses MPa (megapascals) under CSA A23.1, not PSI. Your supplier will ask you for MPa when you call.
The calculator recommends the right MPa for your project automatically in project mode. Each strength level adds to your base price: 30 MPa adds about $20/m³, 32 MPa adds about $32/m³, and 35 MPa adds about $45/m³ over the 25 MPa baseline.
Set Your Waste Factor
The standard waste factor for concrete is 10%. That covers spillage, slight over-excavation, uneven subgrade, and the small amount left in the drum when the truck leaves. The calculator defaults here.
When to go higher:
- Rocky or uneven subgrade: Use 12 to 15%. Irregular voids in the base consume more concrete than your flat-surface calculation accounts for.
- Hot weather pours in Alberta or Saskatchewan: Add 5% for any summer pour over 30 minutes from the batch plant. Heat accelerates set time and you may waste the tail end of a load.
- Your first pour: Just use 15%. The math is right. The execution usually isn't on the first job.
Running short mid-pour is far more expensive than over-ordering by half a cubic metre. A cold joint in a slab is a permanent weak point.
Read Your Results
The calculator gives you everything you need to make an order decision.
- Volume: Net cubic metres (your dimensions only) and order volume (net + waste). This is the number you give your ready-mix supplier.
- Cubic yards: The same volume converted for reference. Some older estimating databases use cubic yards. 1 m³ = 1.308 yd³.
- 30 kg bag count: How many bags to buy if you're mixing by hand. One bag = 0.012 m³. At $8 to $11 per bag in 2026, bagged concrete is cost-effective when your pour is under 1 m³. Above that, the time cost of mixing and the cold joint risk tip the balance toward ready-mix.
- Truck loads: Your order volume divided by 8 m³ (standard drum truck capacity). Anything under 5 m³ puts you in short-load territory.
- Pour time estimate: Calculated at 3.5 m³/hr, which is a standard residential pour rate with a 4-person crew.
- Pump truck: The calculator flags this when your pour exceeds 4 m³ or when site access likely limits direct chute delivery. Pump truck rental runs $150 to $300/hr in Canada in 2026, billed separately from the concrete.
- Material cost (CAD): Your order volume x effective price per m³, which includes the MPa adder and air-entrainment adder. This is material only. Labour, formwork, rebar, delivery surcharges, and taxes are on top.
- Installed cost range: A rough total project budget at 2.5 to 4x your material cost. That multiplier covers labour, formwork, reinforcement, finishing, and contractor overhead. Use it for early-stage budgeting, not for bidding.
Concrete Volume Formulas by Shape
Every concrete calculation is a volume calculation. Here's the formula for each shape.
Add your waste factor to every result before ordering.
Concrete Bags vs. Ready-Mix: Which One for Your Job?
You've got a small pour coming up and you're not sure whether to call the batch plant or grab bags from the store. Here's the rule.
That's it. No guessing involved. The concrete cost calculator flags the short-load threshold automatically so you always know which side of the line you're on.

Concrete Cost Per Square Foot in Canada — by City (2026)
Most Canadian homeowners and contractors think in square feet, not cubic metres. Here's what a standard concrete slab costs per square foot across Canada's major cities in 2026, calculated at 25 MPa air-entrained ready-mix for two common thicknesses: 4 inches (100mm) for patios and basement floors, and 5 inches (125mm) for driveways and garage floors.
These are material-only costs in CAD. Add 2.5 to 4x for full installed cost including labour, formwork, rebar, and finishing.
| City | Province | Price/m³ | Cost/ft² at 4" | Cost/ft² at 5" |
|---|---|---|---|---|
| Calgary | AB | $195 | $1.84 | $2.30 |
| Edmonton | AB | $190 | $1.79 | $2.24 |
| Vancouver | BC | $240 | $2.27 | $2.83 |
| Surrey | BC | $238 | $2.25 | $2.81 |
| Victoria | BC | $235 | $2.22 | $2.77 |
| Kelowna | BC | $248 | $2.34 | $2.93 |
| Toronto | ON | $210 | $1.98 | $2.48 |
| Mississauga | ON | $208 | $1.96 | $2.45 |
| Ottawa | ON | $200 | $1.89 | $2.36 |
| Hamilton | ON | $198 | $1.87 | $2.34 |
| London | ON | $196 | $1.85 | $2.31 |
| Montreal | QC | $195 | $1.84 | $2.30 |
| Quebec City | QC | $192 | $1.81 | $2.27 |
| Winnipeg | MB | $200 | $1.89 | $2.36 |
| Saskatoon | SK | $198 | $1.87 | $2.34 |
| Regina | SK | $200 | $1.89 | $2.36 |
| Halifax | NS | $205 | $1.93 | $2.42 |
| Moncton | NB | $205 | $1.93 | $2.42 |
| St. John's | NL | $220 | $2.08 | $2.60 |
| Charlottetown | PE | $215 | $2.03 | $2.54 |
Concrete cost per square foot varies by thickness, mix strength, and city. The numbers above use 25 MPa air-entrained as the Canadian residential baseline. For garage floors (30 MPa), add about $0.19/ft² at 4" thickness. For structural foundation concrete (35 MPa), add about $0.42/ft².
CSA A23.1 Mix Strength Guide
Canada's concrete standard uses MPa, not PSI. When you call your supplier, you'll ask for 25 MPa or 30 MPa, not 3,500 PSI.
Frost Depth and Footing Depth by Province
Your footing must sit below the frost line. Pour it above the line and it moves with the ground through freeze-thaw cycles. That means cracked walls, shifted structures, and failed inspections.
The frost depth presets in the footing and post hole inputs are set by province automatically when you select your location.
Rebar and Reinforcement Reference
Concrete handles compression well but fails in tension without reinforcement. Every structural pour needs rebar or wire mesh. Here's what Canadian residential projects typically use:
Rebar costs $1.20 to $1.80 per linear metre for 10M and $1.80 to $2.50 per linear metre for 15M in Canada in 2026.
Common Concrete Calculation Mistakes
We've reviewed thousands of concrete takeoffs at Blaze Estimating. These are the mistakes that show up most often.
Point is: the math is simple. The mistakes come from rushing the inputs.
When to Call a Professional Estimator
This concrete cost calculator handles volume accurately. That's its job. But volume is only the starting point on complex projects. For full project scopes, our concrete estimating services cover everything from rebar schedules and formwork to complete CSI division breakdowns.
You need a professional estimator when:
- Your project has structural elements (foundations, load-bearing walls, columns) that require an engineer's stamp and a detailed rebar schedule
- You're bidding a multi-element project with different mix strengths, thicknesses, and pours at different times
- Your quote needs to go out in 20-48 hours and you can't afford a calculation error
- Your scope includes concrete repair or remediation alongside new pours, because those quantities are calculated differently
