10 Best Free Construction Estimating Software Tools (2026)

What counts as best free construction estimating software

The best free construction estimating software is not all free, and it is definitely not all equal. Some tools give you a real free tier you can run a book of jobs on. Others give you a free trial that turns into a bill in a week or a month. A few are just spreadsheet templates. This ranking sorts them honestly, so you know which you can keep using for nothing and which are only free until the timer runs out.

The 10 best free construction estimating software tools, ranked

1. SimplyWise Cost Estimator

   Best for solo operators and small crews whose bottleneck is the quote. Snap a photo of the job and SimplyWise returns a full itemized estimate in about 6 seconds. It is free to try for 7 days, then $29.99 a month or $239.99 a year, and it is built around photo-to-estimate work.

2. Contractor+

   Best genuinely free all-in-one for solo trades. The Freedom plan is a real free tier, not a trial: build estimates, send invoices, and track clients with no credit card and no clock running out. It caps how many estimates and invoices you can send each month, so it suits low-volume operators. Estimating is template-driven, so you still type each line by hand.

3. Free spreadsheet templates

   Best zero-cost starting point. Hundreds of free contractor estimate templates live in Microsoft Excel and Google Sheets, free forever and fully editable. The catch: you type every line, manage your own pricing, and the output looks like a spreadsheet, not a proposal.

4. Joist

   Best simple estimate-and-invoice app to test. Build a line-item estimate on your phone, turn it into an invoice, and collect payment in one place. As of 2026 Joist runs on a 14-day free trial rather than a free tier, so the free window is for evaluation, not the long haul.

5. Clear Estimates

   Best free trial for remodelers who want a cost database. A 30-day free trial unlocks the full product, including a large residential parts database with localized pricing and a library of project templates. It is a trial, not a free tier.

6. Contractor Foreman

   Best free trial for an all-in-one office. A 30-day free trial is offered on every plan. Estimating and invoicing come on all of them, and scheduling, time cards, and change orders start on the Plus plan. There is no permanent free plan, so plan to pick a paid tier when the trial ends.

7. Buildxact

   Best for builders who estimate off plans. Buildxact now runs a free Go plan capped at 5 estimate credits, plus a 14-day trial of the full platform that adds digital takeoff. Paid plans include unlimited users.

8. STACK

   Best free tier for plan-based takeoff and estimating. A free account unlocks Pro-level takeoff and estimating on any project for 7 days, then drops to a free tier with 1 active project a month, up to 300 plan pages, and 50 measurements per project. It is built for drawings, not site photos, and the free tier stays free.

9. PlanSwift

   Best free trial for pure blueprint takeoff. A 14-day free trial gives full access to its drawing-based takeoff and estimating tools. It is built for drawings, not site photos, and the free window is a trial rather than a lasting free tier.

10. Houzz Pro

    Best for design-led remodelers. A free Basic plan covers estimates, invoicing, and the 3D floor planner with no credit card, and a 30-day trial opens the full product. The paid plan is an annual commitment, so treat Basic as your free lane and the trial as a test drive.

Genuinely free versus free trial: how to tell the difference

Some tools here you can keep using free; the rest run out when a trial timer does. The SimplyWise Cost Estimator is free to try, Contractor+ has a real free Freedom plan, and Excel and Google Sheets templates are free forever. Buildxact, Houzz Pro, and STACK add limited free tiers, capped by credits, projects, or basic features. Joist, Clear Estimates, Contractor Foreman, and PlanSwift are free trials that end after 14 to 30 days.
