Stair Cost Calculator
Answer a few questions about your staircase (style, material, and whether it's a new build or a replacement, plus rough dimensions) and get a starting price range in a couple of minutes. This produces a range, not a quote, and that's on purpose: the numbers below explain exactly how the two are different and why.

A planning range from the same rules Dave quotes with — not a quote. Every number here is provisional until Dave has measured your stairs on site and approved the scope. The firm number comes from your $150 site visit, credited toward the job.
Want the theory first? How staircase pricing works
How this estimate works
The calculator asks about the same handful of things that move a staircase price: staircase style, material, and scope (new build versus replacement), plus approximate dimensions. It's built from typical project data across those categories, which is what makes it fast, and also what makes it a range instead of a firm number.
Estimate vs. final quote
This is the most important thing on the page: your online estimate is a starting range, not a final price. The firm quote comes from a paid site visit, where Dave measures your actual space, confirms material availability, and accounts for anything specific to your site (access, structural conditions, permit requirements) that a form on a screen can't see.
How accurate is the online estimate?
It's useful for budgeting and comparison shopping, but it's not a substitute for an in-person assessment. The same factors that drive real cost (material, design complexity, labor, and permits) are things a form can approximate but can't fully capture the way a site visit can.
What affects my price the most?
The same factors covered in our staircase cost guide: material, design complexity, labor, permits, and site conditions. We keep the explanation there rather than repeating it in full here.
Why do I have to pay for a site visit?
A paid site visit filters for serious projects and makes sure the quote you get is accurate the first time, rather than a low online number followed by a higher one once someone's seen the job. It's a direct trade: a small upfront cost for a number you can build a budget around.
Is the estimate binding?
No. It's a planning tool, not a contract. Final pricing is set at the paid site visit and formal quote stage, after the details above have been confirmed in person.
About This Estimate
This estimate is a starting point based on typical project data. Your final price is confirmed after a paid on-site visit.
