TryBuildCalcConcrete Pump Order Calculator(Pumped Pour Order & Time Estimate)
Use this concrete pump order calculator to estimate order volume, truck loads, and pour time for a pumped ready-mix concrete pour.
Find out how many transit mixer loads your pour needs and avoid an unplanned top-up order or an unexpected small-load surcharge.

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.

Pumped concrete order and pour time estimate
This page is pre-filled with Concrete Pump selected as the pour method, which the calculator uses to estimate a longer per-truck unloading time than a direct chute pour.
Pumping adds priming, hose repositioning, and pump flow-rate time to each load compared to direct discharge — factor this into your site schedule.
- Default pour method: Concrete Pump.
- Pump pours use a longer estimated time per truck.
- Add a pump charge per m³ for a full cost estimate.
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
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.
Input Values Used
| Input | Value |
|---|---|
| Length x Width x Thickness | 10 m x 6 m x 150 mm |
| Wastage | 3% |
| Concrete grade | M25 |
| Transit mixer capacity | 6 m³ |
| Supplier minimum order | 3 m³ |
| Pour method | Concrete Pump |
Step 1 - Theoretical volume
| Item | Formula | Result |
|---|---|---|
| Theoretical volume | Length x Width x Thickness | 9 m³ (317.8 cft) |
Step 2 - Order volume
| Item | Formula | Result |
|---|---|---|
| Order volume | 9 x (1 + 3%) | 9.27 m³ (12.12 yd³) |
Step 3 - Truck loads
| Item | Formula | Result |
|---|---|---|
| Full loads | floor(9.27 ÷ 6) | 1 |
| Partial (final) load | 9.27 − (1 x 6) | 3.27 m³ |
| Total trucks to order | 1 full + 1 partial | 2 |
Step 4 - Pour time and cost
| Item | Formula | Result |
|---|---|---|
| Estimated pour time | 2 x 35 min | 70 min (~1.2 hr) |
Therefore, for this pour you need approximately 9.27 m³ of M25 concrete, delivered in 2 truck loads, taking roughly 1.2 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.
