Why the Closing Cost Calculator Niche?

 High Value Traffic With Low Competition

When someone searches for “closing cost calculator,” they’re usually preparing to make a massive financial decision. Buying or selling a house. That means:

  • High purchase intent

  • Costly PPC ads

  • Demand for financial tools

Despite that, there’s a surprising lack of interactive, AI-enhanced calculators. Existing sites like Zillow or NerdWallet offer basic tools, but none integrate AI for real time, personalized tips.

The 5 Essential Pages You Need

Your site doesn’t need to be complicated. The 5 page layout includes:

  1. Homepage / Calculator Tool

    • AI-generated estimates

    • Inputs: ZIP code, price, seller/buyer status

  3. Opt in Page (Optional)

    • Collects email leads

You can expand to include more pages (e.g., “How to Sell Without a Realtor”), but this structure is enough to get started.

Monetization Without SEO or Selling

Traffic Without Traditional SEO

  • Press releases to distribute your AI tool to local and national media

  • YouTube and social media to share quick tips and demos

  • Content posts about saving money on closing costs with CTAs linking to the calculator

 Earning With High CPC Niches

Even if “closing cost” keywords have low ad value ($0.30–$1.67), related terms like:

  • “Mortgage lenders” ($7 CPC)

  • “Sell my house” ($11 CPC)

  • “Refinance calculator” ($9+ CPC)

…can drive lucrative pay per click and affiliate income.
