How Accurate Are Online Remodel Cost Estimators?

August 14, 2025

What Spokane & North Idaho Homeowners Need to Know Before Trusting That Number


Let’s be honest — we’ve all done it.


You’re thinking about remodeling your kitchen or adding a bathroom, and you punch a few numbers into an online cost estimator. Thirty seconds later, it spits out a number that feels… suspiciously low. Or maybe shockingly high.

So how accurate are those remodeling cost calculators?

At The Building Company, we work with homeowners across Spokane, Coeur d’Alene, and North Idaho who are trying to budget responsibly. Online tools can be a helpful starting point — but they’re often misleading when it comes to real-world pricing and scope.

Here’s what you need to know before you trust that number.

🧮 Online Estimators Are Averages — Not Reality

Most cost calculators are built on national or regional averages. They pull data from a wide range of project types, finishes, and market conditions. But here’s the problem:

  • There’s no “average” kitchen in Spokane. Or CDA. Or Sandpoint.
  • There are 1,400-square-foot ranchers and 5,000-square-foot lakeside homes — and everything in between.
  • That’s why many calculators are off by 20–60% (or more) when compared to actual local bids

🛠️ What They Often Leave Out

Even the better calculators can miss or misrepresent key cost factors, like:

  • Permits — Different jurisdictions (Spokane vs. Hayden vs. Liberty Lake) have different fees and requirements
  • Design — Custom design work isn’t usually included
  • Demo & prep — What’s behind the walls matters (plumbing, wiring, asbestos, rot)
  • Material quality — There’s a world of difference between stock cabinets and custom millwork
  • Site conditions — Sloped lots, narrow access, or older foundations all affect cost

Plus, online tools rarely account for construction logistics like dust protection, project management, or warranty service.

🏡 Local Market Pricing Varies Widely — and Changes Fast

Here in the Inland Northwest, remodeling costs have a huge range — not because contractors are inconsistent, but because material choices, labor complexity, and layout decisions vary so much.

For example:

  • Laminate countertops might cost $25–$45/sf installed
  • Quartz? $65–$100+
  • Handmade tile backsplash? Easily $150/sf with labor

That’s not even touching appliance packages, flooring, or structural changes.

And while some materials have stabilized in 2024, supply chains, fuel prices, and subcontractor availability all continue to affect bids.

🤝 What You Can Use Cost Estimators For

To be fair, we don’t hate cost calculators. They can help you:

  • Compare basic cost ranges between project types
  • Begin thinking in “buckets” (e.g., $50K vs. $150K projects)
  • Ask better questions when meeting with a contractor

Just don’t use them as a quote — or a commitment.
