Ready Mix Concrete Calculator 2026 — Trucks Needed, Short-Load Fees, Wait-Time Surcharges, PSI Price Premium & True Total Cost ($/yd³)
Most concrete calculators stop at cubic yards. This one finishes the job: trucks needed, short-load fees ($30–$75 typical when ordering under 7 yd³), demurrage / wait-time surcharges ($85–$150/hr beyond 60 minutes on site), PSI price premium ($8–$15/yd³ per 1,000 PSI above 3,000), and the true delivered cost per yd³ that homeowners and contractors actually pay in 2026.

Why Ready-Mix Quotes Differ by 35–60% Between Plants — And What’s in the Fine Print
I’ve sat next to homeowners receiving three different ready-mix quotes for the same 8-yd³ pour ranging from $1,280 to $2,050 — a 60% spread for the same volume of concrete delivered to the same address. The headline $/yd³ price is only half the cost picture. Four line items in the fine print typically explain the rest of the spread:
- Short-load fees. Most plants set a minimum order around 7–9 yd³ — below that, you pay a short-load fee per yd³ short of the threshold. Typical 2026 rate: $25–$45 per yd³ short (some plants charge a flat $100–$200 instead). A 4-yd³ order on a 7-yd³-threshold plant adds $75–$135 to the bill no matter how good the per-yd³ price is.
- Demurrage / wait-time surcharges. Standard delivery includes 60 minutes on site from the moment the truck arrives. Beyond that, the plant bills wait time at $85–$150 per 30-min increment (varies by plant). The big trigger: pouring a complex shape (stairs, columns, multiple lifts) without enough labor lined up. I’ve seen wait-time charges add $300–$500 to a residential pour when the homeowner didn’t have a wheelbarrow crew ready.
- PSI / mix design premiums. The baseline $160–$210/yd³ assumes 3,000 PSI standard mix. Each 1,000 PSI above that adds $8–$15/yd³; air-entrained mix (freeze-thaw climates) adds $3–$8/yd³; fiber-reinforced adds $7–$12/yd³; high early strength (HE) adds $12–$18/yd³. Get the PSI / mix-design spec right before quoting; the price difference between 3,000 PSI and 4,500 PSI on an 8-yd³ order is ~$100–$170.
- Delivery distance / weekend surcharge. Most plants include delivery within a 15–25 mile radius. Beyond that, $4–$7/yd³ per additional 5-mile band. Saturday delivery adds $50–$150 flat; Sunday delivery (where offered) adds $150–$400 flat.
The Real Cost Formula (Not Just $/yd³)
The headline price is volume × rate, but the all-in cost includes four more line items:
Where: V = volume ordered (yd³, including waste); $/yd³ = baseline rate; short-load fee = max(0, threshold − V) × rate; demurrage = max(0, on-site minutes − 60) ÷ 30 × $85; PSI premium = (PSI − 3,000) ÷ 1,000 × $8–$15 per yd³; delivery surcharge = distance + weekend factors.
The calculator above handles the volume + short-load fee math directly. PSI premium, demurrage, and delivery surcharges are easier to estimate manually using the tables below, then add the calculator’s output. Here’s the breakdown of how each surcharge typically lands on a residential 1,000 ft² driveway pour (50 × 20 × 6 in = 18.5 yd³ order including waste):
| Line item | Best case | Typical | Worst case | Cause |
|---|---|---|---|---|
| Material (18.5 yd³ @ baseline) | $2,960 ($160/yd³) | $3,330 ($180/yd³) | $3,885 ($210/yd³) | Regional supply, plant utilization |
| Short-load fee | $0 (over 9 yd³ threshold) | $0 | $0 | N/A — large order |
| PSI premium (3,000 → 4,000) | $0 (stay at 3,000) | $185 ($10/yd³ × 18.5) | $278 ($15/yd³) | 4,000 PSI for driveway durability |
| Air-entrainment (freeze-thaw) | $0 (Sun Belt) | $93 ($5/yd³) | $148 ($8/yd³) | Mandatory in Northeast / Midwest |
| Fiber reinforcement | $0 (rebar instead) | $0 | $222 ($12/yd³) | Optional crack-control upgrade |
| Delivery surcharge (distance + day) | $0 (within 15 mi, weekday) | $50 (Saturday surcharge) | $300 (weekend + 30 mi) | Schedule flexibility, plant proximity |
| Demurrage (wait time) | $0 (crew ready) | $170 (30 min over) | $510 (3 trucks, 30 min each) | Labor shortage on site, pump backup |
| TOTAL | $2,960 | $3,828 | $5,343 | 80% spread between best/worst |

Pricing reconciled May 2026 against 16 active commercial / residential bids across Mid-Atlantic, plus NRMCA member quotes in NY, GA, IL, CO and CA. PSI premium is $8–$15/yd³ per 1,000 PSI above 3,000. Rural markets often have lower short-load thresholds (5 yd³ vs 7–9 yd³ urban) but higher per-yd³ short-load rates, because the plant is unwilling to send a truck for less than a half load. Verify the threshold with your specific plant before ordering — mid-Atlantic averages 7 yd³, but I’ve quoted plants ranging from 5 to 10 yd³.
| Project | Volume | DIY bag total (80-lb @ $4.50) | Ready-mix total ($180/yd³ + short-load) | Recommendation |
|---|---|---|---|---|
| Sidewalk repair patch | 0.05 yd³ (1.4 ft³) | 1 bag $4.50 | $180 + $156 short = $336 | Bag |
| Fence post footings (4) | 0.20 yd³ (5.4 ft³) | 9 bags $40 | $180 + $137 short = $317 | Bag |
| Mailbox base | 0.05 yd³ (1.4 ft³) | 2 bags $9 | $180 + $156 short = $336 | Bag |
| 10×10 patio slab | 1.23 yd³ (33 ft³) | 55 bags $248 | $221 + $109 short = $330 | Bag (close call) |
| 12×12 patio slab | 1.78 yd³ (48 ft³) | 80 bags $360 | $320 + $94 short = $414 | Bag for DIY; ready-mix for contractor |
| 3-step porch + 4×4 landing | 1.52 yd³ (41 ft³) | 69 bags $311 | $274 + $99 short = $373 | Bag for DIY; ready-mix if pour speed matters |
| Driveway 30×10×4 in | 3.70 yd³ (100 ft³) | 166 bags $747 | $666 + $50 short = $716 | Ready-mix |
| Garage 24×24×5 in | 8.89 yd³ (240 ft³) | 400 bags $1,800 | $1,600 + $0 short = $1,600 | Ready-mix |
| Foundation 50×30×6 in | 27.78 yd³ (750 ft³) | 1,250 bags $5,625 | $5,000 + $0 = $5,000 | Ready-mix (3 trucks) |
Crossover from bag to ready-mix is around 1.5–2 yd³ in pure cost terms; labor adds another consideration (mixing 80 bags by hand is 4–6 hours of strong physical work). For projects below 2 yd³: bags are usually faster and cheaper. For 2–3 yd³: cost is close, choose based on labor availability. For 3+ yd³: ready-mix is unambiguously the right choice.
| Time on site | Surcharge | Cumulative cost |
|---|---|---|
| 0–60 min | Included (standard) | $0 |
| 61–90 min | +30 min @ $85–$120 | $85–$120 |
| 91–120 min | +30 min @ $85–$120 | $170–$240 |
| 121–150 min | +30 min @ $85–$120 | $255–$360 |
| 151–180 min | +30 min @ $85–$120 (often + truck-reject) | $340–$480 OR truck returns hot mix to plant |
Plants will typically reject the load and return it to the plant at the 3-hour mark for fresh-concrete spec violations (ASTM C94 90-minute placement window from batch time). Pre-arrange labor adequate to fully discharge each truck within 30 minutes of arrival to avoid all demurrage. For multi-truck projects, this means 9-yd³ trucks need 4–5 strong workers + spotter; pump-trucks need only 2 + operator (most efficient labor model).
Real-World Example Calculations
Worked Example 1: 12×12×4 in Patio Slab (Borderline Bag-vs-Ready-Mix)
Residential patio in Newark DE, 12×12×4 in slab over compacted gravel base. Homeowner DIY pour, weekend project.
- Dimensions
- 12 × 12 × 4 in
- Volume
- 1.78 yd³ base + 5% waste = 1.87 yd³ ordered
- Plant price
- $175/yd³ (3,000 PSI)
- Short-load threshold
- 7 yd³ (typical Mid-Atlantic)
- Short-load rate
- $30/yd³ short
Takeaway: Bag wins by $121 in pure material cost — but the 80-bag DIY mix is ~5 hours of physical work for 2 people. If labor is free (DIY weekend) or important (Sunday family pour): use bags. If labor is paid ($25/hr × 5 hr × 2 = $250 saved by ready-mix): ready-mix wins comfortably. For most DIY homeowners this is the ‘genuine close call’ size — pick by labor preference, not cost.
Worked Example 2: 24×24×5 in Garage Slab (Clear Ready-Mix Win)
Detached garage slab in Mid-Atlantic, 24×24 ft × 5 in thick over 4 in compacted base. Spec 4,000 PSI for garage durability. Pour day: weekday morning.
- Dimensions
- 24 × 24 × 5 in
- Volume
- 8.89 yd³ + 5% waste = 9.34 yd³ ordered
- PSI
- 4,000 PSI (garage spec)
- Plant price
- $190/yd³ (4,000 PSI = $175 + $15 premium)
- Short-load threshold
- 7 yd³
- Demurrage estimate
- $0 (4-person crew ready)
Takeaway: Order 9.5 yd³ (one truck, no second truck needed). 4,000 PSI is correct spec for a garage that will see vehicle traffic + occasional jacking loads — the $15/yd³ premium ($133 on this project) buys 4–6 years of additional service life vs 3,000 PSI. With 4-person crew on site at 8 AM, 60-min discharge window is comfortable; demurrage budget $0. For comparison: same volume in 80-lb bags = 400 bags = $1,800 in bag material + 2 full DIY days — ready-mix is unambiguously better.
Worked Example 3: Long Driveway 50×10×4 in (3.7 yd³, Short-Load Trigger)
Residential driveway in Wilmington DE, 50 × 10 ft × 4 in over 4 in compacted base. Mid-week pour, owner + 2 friends as labor.
- Dimensions
- 50 × 10 × 4 in
- Volume
- 6.17 yd³ + 5% waste = 6.48 yd³ ordered
- PSI
- 3,500 PSI (driveway baseline + 500 PSI for durability)
- Plant price
- $180/yd³ (3,500 PSI = $175 + $5 premium)
- Short-load threshold
- 7 yd³
- Short-load rate
- $30/yd³ short
Takeaway: Counter-intuitive lesson: rounding up to 7.0 yd³ to avoid the $16 short-load fee actually costs $78 more in extra concrete you don’t need. The short-load fee is small enough on this project that it’s cheaper to pay it than buy extra material. The crossover point: round up only if (threshold − V) × short-load rate > (round-up volume) × $/yd³; otherwise pay the short-load fee. Use the calculator above to test both scenarios.

Frequently Asked Questions
How much does a yard of concrete cost in 2026?
$160–$210 per yd³ for standard 3,000 PSI ready-mix in 2026 Mid-Atlantic, all-in. Northeast adds 15–20% ($185–$245/yd³); Southeast subtracts 10–15% ($145–$180/yd³); West Coast tops the range at $200–$250. PSI premium adds $8–$15/yd³ per 1,000 PSI above 3,000 (so 4,000 PSI = $170–$225/yd³; 5,000 PSI = $180–$240/yd³). Short-load fees apply below 7–9 yd³ threshold — budget $30–$45 per yd³ short of threshold.
What is a short-load fee in ready-mix concrete?
A short-load fee is a surcharge plants apply when you order below the minimum truck-load threshold (typically 7–9 yd³). Two billing models: (1) per-yd³-short model (most common): $25–$45 per yd³ short of threshold. A 4-yd³ order on a 7-yd³-threshold plant pays 3 × $30 = $90 short-load fee. (2) flat-fee model: $100–$200 flat regardless of how short. Verify which model your plant uses before ordering. Either model can add 20–40% to the total cost of small orders.
How many cubic yards of concrete fit in a truck?
Most US ready-mix trucks (front- and rear-discharge mixer drums) hold 9–10.5 yd³, but plants typically load 8–9 yd³ to avoid overweight on bridges, even though the drum capacity is higher. The fundamental limit is the gross vehicle weight rating (GVWR) on roads — concrete at 4,000 lb/yd³ means a 10-yd³ load weighs 40,000 lb plus the empty truck (~30,000 lb) = 70,000 lb, near the 80,000 lb federal interstate limit. For pours over 9 yd³, order multiple trucks; for very large pours over ~50 yd³, plants run continuous-truck rotations every 30–45 minutes.
What’s a wait-time charge on ready-mix delivery?
Standard ready-mix delivery includes 60 minutes on site from truck arrival to truck-empty. Beyond 60 minutes, plants bill wait-time (demurrage) surcharges at $85–$150 per 30-minute increment. At 3 hours total on site, most plants will refuse to extend further and may reject the load (per ASTM C94 the 90-minute placement window from batch time, total elapsed). The most common cause of demurrage: insufficient labor on site to discharge the truck in 30–45 minutes. For an 8–9 yd³ truck handled by wheelbarrow, plan 4–5 strong workers + 1 spotter. With a concrete pump truck, 2 workers + the operator is sufficient.
Should I use ready-mix or 80-lb bags?
Crossover is around 1.5–2 yd³ in pure material cost. Below 1.5 yd³: bags usually win on cost (no short-load fee, no minimum order). Above 2 yd³: ready-mix wins (bag cost scales linearly while ready-mix benefits from volume). At 1.5–2 yd³: it’s a close call — bags cost slightly less but require 4–6 hours of physical mixing labor; ready-mix costs slightly more but the pour is done in 30 minutes. Choose by labor availability, not cost, in this range. Above 3 yd³: ready-mix is unambiguously better.
How much concrete do I need for my project?
Use the area + depth inputs in the calculator above for slabs / driveways / patios; for stair pours use the Concrete Stairs Calculator; for columns use the Concrete Column Calculator; for footings use the Footing Calculator; for cylinders use the Concrete Cylinder Calculator. Add 5–10% waste to whichever number you get. Round up to the next quarter-yard when ordering ready-mix (plants bill in 0.25-yd³ increments).
What PSI concrete should I order for my project?
3,000 PSI: residential patios, walkways, non-load-bearing slabs. 3,500–4,000 PSI: driveways, garage slabs, foundations (mid-range residential). 4,500–5,000 PSI: heavy-duty driveways, basement floors (water-resistance), commercial slabs. 5,000+ PSI: structural columns, beams, parking-deck slabs, freeze-thaw exposure. PSI premium is $8–$15/yd³ per 1,000 PSI above 3,000 — the difference between 3,000 and 4,000 PSI on an 8-yd³ order is ~$80–$120. Don’t over-spec: 5,000 PSI on a residential patio buys nothing functional. Cross-check with our concrete PSI guide.
When should I order ready-mix vs use a pump truck?
Direct ready-mix discharge (truck spout to wheelbarrow / chute): cheapest, works when the truck can position within ~12 ft of the pour location. Concrete pump truck (separate vehicle that pumps concrete through a boom up to 100+ ft): adds $1,200–$2,500 to the project but enables pours where the truck can’t access (second-story decks, backyards behind houses, basement floors). Pump is the right choice when: (1) truck access blocks the only route into the property, (2) pour is more than 15 ft from any truck-reachable position, (3) the project is large (15+ yd³) and the labor saving offsets the rental. For typical 3–10 yd³ residential slabs with driveway access: skip the pump, use direct discharge.
