Building CostNest: From 0 to 72 Free Online Calculators

Hi everyone,

I'm a full stack web developer and recently launched CostNest, a growing collection of free online calculators and tools.

What started as a small project has grown to 72 calculators covering finance, health, construction, productivity, garments, and everyday calculations.

Along the way I've learned a lot about Next.js, SEO, site performance, and building tools that people actually use.

Some recent milestones:

• 72 calculators live
• 54 pages indexed by Google
• Over 3,000 search impressions
• Growing organic traffic

My goal is to continue expanding CostNest and make it a useful resource for anyone who needs quick and accurate calculations.

I'd love to hear your feedback:

• What calculators would you like to see?

• Have you built a similar project?

• Any advice for growing a utility website?
