Concrete Prices in Idaho — Cost Guide + Calculator
There is no verified statewide ready-mix price in the research supplied for this page. For a useful Idaho estimate, measure your project, request a delivered quote for your address, and enter that price below. The calculator separates material, delivery and optional installation instead of presenting a made-up local average.
Quick answer
How much does concrete cost in Idaho?
A price per cubic yard depends on the exact delivery address, mix specification, order size and what the supplier includes. A search result cannot replace a current written quote. Ask for the ready-mix rate per cubic yard and list delivery, short-load, fuel or other charges separately. If you are comparing an installed slab, also request preparation, reinforcement, finishing and labor as separate lines. That is the only honest way to compare the material price with an all-in project total.
This page is a planning draft, not a published Idaho price survey. Local price ranges, city comparisons and their source dates still need editorial verification before publication. The tool remains useful now: it calculates the quantity from your dimensions and applies the quote you obtained, without changing the input price behind your back.

Idaho Concrete Cost Calculator
Start with your measured dimensions. Enter a delivered price from a Idaho supplier when you have one; no state price is preloaded.
The concrete total appears after you enter a delivered price per cubic yard. Add only fees excluded from that rate; installation is optional. Tax, reinforcement and site work are not inferred.
Local quote worksheet
Compare Idaho concrete quotes on the same basis
For a quote to be comparable, give each supplier the same dimensions, thickness, required strength or engineer's specification, delivery address and proposed pour date. Ask whether the quoted amount covers material only or includes placing and finishing. A low per-yard figure can be misleading when delivery and small-order fees are omitted. Record each answer rather than combining different scopes into a single statewide “average.”
| Quote area | Ask for | Record separately |
|---|---|---|
| Boise | Delivered price per cubic yard for your mix | Delivery, minimum order and fees |
| Idaho Falls | The same mix and quantity | Availability and delivery terms |
| Coeur d'Alene or another area | Price for the exact job address | Installation as a separate quote |
These areas are prompts for obtaining quotes, not a claim that prices or suppliers are the same across Idaho. A city list is not a verified price map. When current local figures are supplied and checked, this draft can replace the worksheet with dated and sourced comparisons.
Methodology
How the Idaho calculator works
For a rectangular slab, the calculator multiplies length by width by thickness in feet, divides cubic feet by 27 to convert to cubic yards, and applies the allowance you selected. It does not round the order to a truck size or assume that every project needs the same allowance. Check the actual amount with your supplier or contractor before ordering. An irregular slab, footing or stepped grade needs separate measurements for each section; add the volumes instead of pretending the whole project is one rectangle.
Ready-mixed concrete is sold by volume in cubic yards or cubic meters, according to the National Ready Mixed Concrete Association's yield guidance. The bag figure uses the approximately 0.60 cubic-foot yield stated in the Quikrete 80 lb Concrete Mix technical sheet; verify yield for the exact bagged product you buy. Bag count is a quantity comparison, not a claim that bags cost less than delivered concrete.
The material estimate multiplies your entered price per cubic yard by the calculated volume. Fixed fees are added once. If you also enter an installation quote per square foot, the tool multiplies it by the project area and adds it to the displayed total. These inputs may overlap with a contractor's all-in bid, so do not enter an all-in installed rate together with material and delivery unless the scope genuinely excludes them.
Questions
Idaho concrete price questions
What is the price of ready-mix concrete per yard in Idaho?
This draft does not state an unverified statewide number. Request a current delivered quote for the job address and mix you need, then use that rate in the calculator. Compare quotes dated close together and check whether fees and taxes are included.
How much concrete does a 20 × 20 ft slab need?
At 4 inches thick, the geometric volume is about 4.94 cubic yards before any allowance. Change the dimensions or thickness above to match your project. The final order should reflect the actual formwork and supplier guidance, not a generic slab example.
Do bagged and ready-mix prices mean the same thing?
No. Ready-mix is normally quoted per cubic yard delivered; bagged mix is sold by bag with a product-specific yield. Compare the same volume and include handling, equipment and delivery before deciding which option fits the job.
