Best Free Concrete Estimating Software in 2026
If you run a concrete business, you've probably searched for free estimating software at least once. This guide is an honest roundup of the free options concrete and flatwork contractors actually have in 2026: free versions, free trials and plain free templates. It includes our own product, TradeBid, but it also covers the competitors, and it says when one of them is the better fit.
One thing to know up front: truly free, forever-free estimating software is rare. Most tools offer a free trial, and a few offer a limited free version. Below, we say which is which, based on each vendor's own pricing page. Plans change, so check before you decide.
What a concrete estimate needs to cover
Before comparing tools, it helps to know what a solid concrete bid includes. Your software should handle cubic yards, square feet of slab, linear feet of footing and forms, and pounds or tons of rebar. A typical line-item concrete estimate covers:
- Excavation and base prep (gravel, compaction)
- Forms and form labor by linear foot
- Rebar or wire mesh, chairs and ties
- Concrete by the cubic yard, with a waste factor
- Pump or buggy time
- Placing, finishing and saw cutting
- Curing, sealing and cleanup
- Exclusions such as testing, winter protection and permits
Most lost money on concrete bids comes from yardage. A slab that's a half inch thicker than drawn, or a footing that gets over-dug, eats the margin fast. Whatever tool you pick, make sure it shows the math from area and depth to yards so you can check it.
Quick comparison
| Tool | Free option (per vendor's site) | Best for | |---|---|---| | TradeBid | 7-day free trial, 3 bids and 1 takeoff included, card required | Subs who want a finished, branded bid fast | | STACK | Free version of Takeoff & Estimate | Teams that want cloud takeoff and are ready to set up assemblies | | PlanSwift | 14-day free trial, no credit card | Estimators on Windows who want deep takeoff and Excel links | | Bluebeam | Free trial | Teams that already live in PDF markup | | Joist | 14-day free trial, no credit card | Small residential jobs, estimates and invoices from a phone | | Spreadsheet or template | Free | Very low bid volume, or as a backup |
1. TradeBid: best for getting a finished concrete bid out fast
Free option: Try TradeBid free for 7 days: 3 bids and 1 takeoff included. A card is required to start, and you won't be charged if you cancel before the trial ends.
TradeBid is construction bidding software for subcontractors. You upload plan PDFs, a scope document, jobsite photos or plain notes, pick Concrete as your trade, and TradeBid drafts an editable line-item bid with quantities, labor, materials, markup and exclusions. You review and change every line, then export a branded PDF proposal to send to the GC or owner. It works in English and Spanish and runs in a browser, so it works on a Mac, a PC or a tablet.
Good fit if: you bid your own work, you want a professional proposal rather than just quantities, and you don't want to spend weeks building assemblies.
Not the best fit if: you need a full project management system after the bid, or your company has a dedicated estimator who wants detailed manual takeoff tools.
After the trial, plans start at $149 a month (Apprentice, up to 5 bids a month), or you can buy a single bid for $100. See pricing or look at a sample bid first. You can read more on the Concrete page.
2. STACK: best free version for cloud takeoff
Free option: STACK's pricing page says it offers a free version of its Takeoff & Estimate software (source). STACK also has a dedicated concrete page (source).
STACK is a well-known cloud takeoff and estimating platform, and its free version is a real way to try cloud takeoff without paying. Some users on public forums mention that setting up assemblies takes time.
Good fit if: you want to measure plans in the browser and you're willing to set up your own assemblies and pricing.
Not the best fit if: you want a branded proposal with little setup, or the paid plan price is too high for your bid volume.
3. PlanSwift: best trial for detailed takeoff on Windows
Free option: PlanSwift's pricing page offers a 14-day free trial of every feature with no credit card required (source). PlanSwift also covers concrete takeoff (source).
PlanSwift is a long-standing takeoff tool. PlanSwift describes itself as a Windows desktop application, with assemblies, custom formulas and a live link to Excel. Good fit if: you work on Windows and want deep, customizable takeoff.
Not the best fit if: you're on a Mac, or you want a finished proposal without building it yourself.
4. Bluebeam: best if you already mark up PDFs
Free option: Bluebeam offers a free trial on its site (source).
Bluebeam is best known as PDF markup software that also handles quantity takeoff. Good fit if: you already use Bluebeam for markups and want to measure in the same tool.
Not the best fit if: you want line-item pricing and a proposal built for you, because Bluebeam focuses on markup and measuring.
5. Joist: best for small residential estimates and invoices
Free option: Joist's pricing page lists a 14-day free trial with no credit card required (source).
Joist focuses on contractors who write estimates and invoices for homeowners and get paid online.
Good fit if: you do small residential concrete jobs and care most about quick estimates and payments.
Not the best fit if: you bid from plan sets for GCs and need takeoff from drawings.
6. A free spreadsheet or template
A spreadsheet is the only option that's free forever. It works for a few bids a month, but formulas break, prices go stale and every proposal looks a little different. If you go this route, start with a clean template like our free construction bid template and keep your labor rates and markups in one place.
Tip: run any free trial on a job you've already bid by hand, then compare the numbers and the time it took.
