I built a free calculator hub that gets straight to the point — no fluff, no login walls

Hey IH 👋

I launched CloutCalculator — a collection of free online calculators across finance, health, math, construction, and more.

The problem I kept running into:

Every time I needed a quick calculation — mortgage estimate, cubic yards for a project, BAC for a story I was writing — I'd land on some bloated site plastered with ads, demanding I sign up before I could see a result. Or the UI was so cluttered I couldn't figure out where to even enter my numbers.

So I built the thing I actually wanted:

• ⚡ Instant results, no sign-up required

• 📱 Clean, mobile-friendly UI

• 🧮 Verified formulas with clear explanations

• 100% free, forever

What's on it right now:

Finance (mortgage, RV loans, Coast FIRE), Health (BMI, BAC, BMR), Construction (concrete, asphalt, cubic yards, board feet), Math, Education, Conversions, and more being added regularly.

Where I'm at:

Still early — focused on SEO, expanding the calculator library, and making sure every tool actually explains the output so users understand the numbers, not just see them.

Would love feedback on:

• Which calculators are missing that you actually use?

• Does the UX feel clean enough or is there anything confusing?

• Any niches (real estate? fitness? budgeting?) I should prioritize next?
