How much are you overpaying for estimating software?
Most US contractors pay $1,000–$4,000 per seat, every year, for takeoff and estimating software — and re-buy it annually now that perpetual licenses are gone. See what you spend today versus OneEstimate, which starts free and tops out at $49/mo for the Pro plan.

Start free — keep your first estimateHow to read these numbers
Competitor figures are advertised or starting annual prices per user that we found publicly in 2026 — always confirm the current quote for your seat count and region, since several vendors now price by quote or by company revenue. Tools also differ in scope: Bluebeam Revu is measurement and markup, RSMeans is cost data, and On-Screen Takeoff and Buildertrend are quote-only, so a like-for-like price is only part of the story. This calculator is a planning estimate, not a quote.
Why estimating software got so expensive
The old model — buy it once, own it forever — is mostly gone. Here is what changed and why it matters to a small contractor.
Perpetual licenses disappeared
Tools like PlanSwift moved to annual subscriptions and retired the buy-once license. If you stop paying, you lose access — so it is a recurring cost forever, not a one-time purchase.
Priced per seat, per year
Premium takeoff suites run $2,000–$3,600 per user per year. Add a second estimator and the bill doubles. Small shops end up subsidizing features built for large GCs.
Add-ons and training cost extra
Trade plug-ins, cost databases and onboarding are frequently sold separately — hundreds more per person. The sticker price is rarely the real price.

Frequently asked questions
What is the cheapest construction estimating software?
OneEstimate has a genuinely free plan ($0) that does takeoff and line-item estimating, which makes it one of the cheapest real options for a small contractor. When you need AI, more estimates, and Excel/PDF export, the Pro plan is $49 per month per seat ($588 a year) — well below the $2,000–$3,600 per-user-per-year that premium takeoff suites charge.
How much does estimating software normally cost?
For full takeoff-and-estimating suites, expect roughly $1,000 to $4,000 per user per year in 2026. PlanSwift is around $1,749–$2,000, STACK runs about $2,988–$3,588, and On-Screen Takeoff and Buildertrend are quote-only and historically higher. Cost-data tools like RSMeans and measurement tools like Bluebeam are cheaper because they only do part of the job.
Why did my estimating software get more expensive?
Most vendors retired perpetual (buy-once) licenses and moved to annual per-seat subscriptions. PlanSwift did this in 2025. That turns a one-time purchase into a cost you pay every year, and the price is per user — so adding estimators multiplies it. OneEstimate keeps a permanently free tier and a flat $49/mo Pro price to break that pattern.
Is a cheaper tool actually good enough?
For most residential and light-commercial contractors, yes — the expensive suites include enterprise features many small shops never use. OneEstimate focuses on the core: AI takeoff, accurate line-item estimates, and clean exports. Start on the free plan and test it on a real bid before you pay anything.
