Recommendation

Step 1: Concrete Material Cost = Order Volume (yd³) × Price per yd³
Step 2: Check if Order Volume < Minimum Threshold → fee applies
Step 3a [Flat]: Short-Load Fee = flat fee amount entered
Step 3b [Per yd]: Short-Load Fee = (Minimum − Order Volume) × fee rate per yd
Step 3c [Pct]: Short-Load Fee = Concrete Material Cost × (fee % ÷ 100)
Step 4: Total Delivered Cost = Material Cost + Short-Load Fee
Step 5: Effective Rate = Total Delivered Cost ÷ Order Volume
Step 6: Bagged Cost = CEIL(Order Volume × 27 ÷ 0.60) × $7.50 per 80 lb bag

How to Use This Short-Load Fee Estimator

  1. Enter your pour volume. Use a concrete slab or footing calculator to determine exactly how many cubic yards you need — with waste factor already added. Enter that number here. If you're ordering in metric, switch the unit to cubic meters; the calculator converts automatically.
  2. Set your truck capacity and minimum threshold. Call your ready-mix plant and ask: "What's your truck capacity and minimum load?" Standard US trucks carry 8–10 yd³. The minimum threshold is the volume below which a surcharge kicks in — often the same as truck capacity, but sometimes lower (e.g. 6 yd³ minimum on a 10 yd³ truck).
  3. Enter the fee structure your plant uses. Select whether they charge a flat delivery fee, a per-yard penalty for each yard short of the minimum, or a percentage surcharge on the order total. Most US plants use a flat fee of $50–$150. Enter the dollar amount from your supplier's quote.
  4. Compare your results before placing the order. The calculator shows your effective cost per yard after the surcharge and compares that against buying 80 lb bags at a hardware store. If the effective ready-mix rate is over $250–$300/yd³, bags are almost certainly cheaper for your volume. Use the verdict to guide your decision.

⚠ Pro Tip: Never accept a short-load fee without asking if you can top up your order to the minimum. For many small pours, adding 1–2 extra yards eliminates the surcharge entirely — at a fraction of its cost. A $100 short-load fee on a 3 yd³ order is $33/yd³ of pure waste. Adding 1 yard at $130/yd³ saves you money and gives you a useful overage buffer.

How Short-Load Fees Are Calculated

Ready-mix plants charge a short-load fee (also called a short-load surcharge or partial-load fee) when your order is below their minimum load threshold. This covers the plant's fixed costs — the truck, driver, fuel, and drum washing — that apply regardless of how little concrete is in the drum. Here's how the fee math works for each fee structure:

Step Formula Example (3 yd³ order, 10 yd³ truck, $130/yd³, $100 flat fee)
1. Concrete material costOrder (yd³) × $/yd³3 × $130 = $390
2. Apply flat short-load fee+ flat surcharge$390 + $100 = $490
3. Effective rateTotal ÷ Order (yd³)$490 ÷ 3 = $163.33/yd³
4. Truck fill percentageOrder ÷ Capacity × 1003 ÷ 10 × 100 = 30%
5. Equivalent bagged costCEIL(yd³ × 27 ÷ 0.60) × $7.50CEIL(81 ÷ 0.60) × $7.50 = 135 bags × $7.50 = $1,012.50

Short-Load Fee Reference Table

Total delivered cost and effective rate — flat $100 short-load fee, $130/yd³ base price, 10 yd³ truck capacity.
Order Volume Truck Fill % Material Cost Short-Load Fee Total Cost Effective $/yd³
1 yd³10%$130$100$230$230.00
2 yd³20%$260$100$360$180.00
3 yd³30%$390$100$490$163.33
4 yd³40%$520$100$620$155.00
5 yd³50%$650$100$750$150.00
7 yd³70%$910$100$1,010$144.29
10 yd³100%$1,300$0$1,300$130.00

At full load (10 yd³) no surcharge applies and effective rate equals base price. Orders under 10 yd³ incur the $100 flat fee, which dilutes the more you order.

Is Ready-Mix Worth It for a Short Load?

The key decision is your effective cost per yard. Once the short-load fee is factored in, smaller orders become progressively more expensive per yard. The table below shows the break-even point relative to buying 80 lb bags at $7.50 each (approximately $337.50/yd³), using a $100 flat fee and $130/yd³ base price.

Decision guide: ready-mix vs bagged concrete at various order sizes (80 lb bags at $7.50, $100 flat short-load fee, $130/yd³ ready-mix).
Order Size Ready-Mix Total Effective $/yd³ Bagged Equivalent Verdict
0.5 yd³$165$330/yd³$152Bags cheaper
1 yd³$230$230/yd³$304Ready-mix cheaper
2 yd³$360$180/yd³$608Ready-mix much cheaper
3 yd³$490$163/yd³$1,013Ready-mix far cheaper
5 yd³$750$150/yd³$1,688Ready-mix far cheaper
10 yd³$1,300$130/yd³$3,375Ready-mix far cheaper

Break-even is typically near 0.5 yd³ or less. For almost any pour exceeding half a yard, ready-mix is cheaper even with the short-load fee — but labor savings from not hand-mixing 135+ bags are also enormous.

For pours under 0.5 yd³ (about 13.5 cubic feet), bags genuinely win on material cost. For post holes, anchor pads, or tiny footings, a couple of 80 lb bags is the right call. Above that threshold, the convenience and quality consistency of ready-mix is nearly always worth the short-load fee.
