Ready-Mix Concrete Cost Calculator(Order Cost With Pump & Surcharge)

Estimate your ready-mix concrete order cost.

Inputs

ℹ️For a slab or footing, use the poured thickness. For a column or wall, use it as the effective depth for a simple rectangular volume.

Order Settings

ℹ️For reference and cost planning only — confirm the actual required grade against your structural drawings.

ℹ️Common truck sizes range roughly 4-10 m³ depending on region and supplier fleet.

ℹ️Optional. Enter 0 if your supplier has no minimum. Orders below this may attract a small-load surcharge.

ℹ️Affects the estimated per-truck unloading time used for the pour time estimate.

Ready-mix concrete order cost estimate

This page is pre-filled with a sample cost per cubic meter to show the full cost breakdown — concrete, pump charge if used, and any small-load surcharge — in one result.

Replace the sample rate with your actual supplier quote for an accurate cost estimate for your specific pour.

  • Default: sample cost per m³ pre-filled.
  • Includes pump charge and small-load surcharge separately.
  • Replace with your actual supplier quote.

What Is a Ready-Mix Concrete Order Calculator?

Ready-mix (RMC) concrete is batched at a plant and delivered by transit mixer truck, ready to place — the question it raises isn't "how much cement, sand, and aggregate do I need" (that's a site-mix question), it's "how many truck loads do I book, how long will the pour take, and what will it cost." Getting the order volume wrong means either an emergency top-up truck mid-pour, or paying for concrete you didn't need.

This calculator converts your pour dimensions (or a directly measured volume) plus a wastage allowance into the exact order volume to book, splits that volume into whole transit mixer truck loads including the final partial load, estimates total pour time from truck count and pour method, and totals cost including an optional pump charge and small-load surcharge if your order falls below your supplier's minimum.

What makes this calculator different:

Most concrete calculators on the web compute cement bags, sand, and aggregate from a mix ratio — useful for site-batched concrete, but the wrong tool once you've decided to order ready-mix. This calculator instead treats the order as a logistics problem: volume in, truck loads and schedule out. It explicitly separates the final partial truck load from full loads (since that's what actually shows up on your last delivery docket), flags orders below a supplier's minimum before you get surprised by a surcharge, and estimates pour duration from truck count and placement method — none of which a mix-ratio calculator answers.

Ready-mix concrete order calculation formula

Step 1 - Theoretical Volume

By Dimensions: Volume = Length x Width x Thickness

By Known Volume: entered directly, unit-converted to m³

Step 2 - Order Volume

Order Volume = Theoretical Volume x (1 + Wastage %)

Step 3 - Truck Loads

Full Loads = floor(Order Volume / Truck Capacity)

Partial Load = Order Volume − (Full Loads x Truck Capacity)

Total Trucks = Full Loads + (1 if Partial Load > 0)

Step 4 - Pour Time and Cost

Estimated Pour Time = Total Trucks x Minutes per Truck (20 chute / 35 pump)

Total Cost = (Order Volume x Rate per m³) + (Order Volume x Pump Rate, if pumped) + Small-Load Surcharge (if below minimum)

Example ready-mix concrete order calculation

This example uses the active calculator inputs above and follows the same four steps from the formula section. Each table shows the value used, the formula applied, and the result produced.

Therefore, for this pour you need approximately 6.18 of M25 concrete, delivered in 2 truck loads, taking roughly 0.7 hours to place.

Limitations

  • This calculator does not design a concrete mix — cement content, water-cement ratio, and admixture dosing are the ready-mix supplier's responsibility, not something this tool computes.
  • It does not verify structural adequacy of the specified grade for a given element — confirm grade against structural drawings or an engineer's specification.
  • Truck capacity, minimum order quantity, and per-truck unloading time are general planning figures — always confirm the actual values with your specific supplier.
  • Pour time is a planning estimate based on truck count and pour method — actual time depends on your crew's placement and compaction speed too.
  • It does not account for irregular pour shapes, sloped pours, curved formwork, embedded voids, or multiple distinct pour elements in one calculation — run the calculator separately for each element, or reduce an irregular shape to an equivalent rectangular volume before entering it.

Disclaimer: This calculator provides approximate results for planning and estimation purposes only. Actual requirements may vary based on site conditions, materials, workmanship, and local building regulations. Always consult a qualified engineer, architect, or construction professional before making final decisions.

FAQ

The total combines concrete cost (order volume x rate per m³), pump charge (if you select pump as the pour method and enter a rate), and a small-load surcharge if your order falls below the minimum you specify — shown as separate line items plus a total.
Many suppliers set a minimum order quantity below which a surcharge applies, since dispatching a truck costs the supplier close to the same amount regardless of load size. Enter your supplier's minimum and surcharge amount to see if your order is affected.
