Ready-mix
Ready Mix Concrete Calculator
Tell the plant a volume they can batch. Concrete Calculator rounds up to the next quarter yard and counts loads for the truck size you set.

Common sizes
Most orders add 5–10% for spillage, uneven ground, and the last bit left in the chute.

Add each pour — slab, piers, steps — and Concrete Calculator totals them.
Quick answer
Ready Mix Concrete Calculator: order yards = waste-adjusted volume rounded up to 0.25. Loads = ceil(order ÷ truck size). Truck size defaults to 10 yd³; set 8 if that is what your plant sends.
Ready Mix Concrete Calculator: Short loads and small pours
Orders under about 3–4 yards often pick up a short-load fee. Concrete Calculator flags the range. It does not invent the fee — ask the dispatcher and compare bags on the same screen. An RMC calculator that only prints neat yards without rounding will under-call what the plant batches.
Staging multi-truck pours
A 22 yd³ order on 10 yd trucks is three loads if you round loads up — confirm whether the plant wants you to order 22.00 or 22.25 after waste. Keep washout and pump plans ready so the second truck is not waiting on a blocked hose.
Ready mix concrete calculator — from neat yards to loads
An RMC calculator should show neat volume, waste-adjusted volume, ordered yards (0.25 steps), and truck loads. Skipping any of those steps is how a crew ends up with a short last corner or an extra truck staged for no reason.
How much ready mix concrete do I need? Same geometry as any Concrete Calculator page, then plant rounding. Strength, slump, and fiber are ticket notes — they do not change the cubic yards unless you change thickness or add another pour.
Concrete truck calculator notes
Rated mixer capacity is not always the load the dispatcher will send to a tight site. Ask. Set truck size to 8 if that is the local fleet. Load count = ceil(order ÷ truck size). A 16.5 yd order on 10 yd trucks is two loads; on 8 yd trucks it is three.
Dispatcher questions worth asking
Ask for the mix strength on the ticket, the slump, whether fiber is included, the short-load threshold, the washout rule, and the backup truck timing if you run short. An RMC calculator that only prints neat yards leaves those conversations for the driveway on pour morning.
If the plant batches in 0.25 yd steps, say the ordered number from Concrete Calculator out loud: neat, waste-adjusted, then rounded. Drivers and dispatchers prefer one clear order quantity over a story about how you measured the patio.

Frequently asked questions
How many yards does a truck hold?
Many mixers are rated ~8–10 yd³. Ask your plant.
What is a short load?
A small order that does not fill the truck; plants often surcharge it.
Bags instead?
Usually under ~0.75–1 yd³, or when the truck cannot reach.
Does ready-mix include labor?
No — this page sizes the material order.
