Hi Marek,

I’m not using the template you mentioned, but I can help calculate a rough estimate for your setup. Based on Railway’s pricing structure, your expected monthly cost would be around $5–10.

Your Setup Will Include:

• WordPress backend (MySQL database + PHP)

• Next.js frontend

Resource Usage Estimate (for ~100 daily visitors / 3,000 per month, with 100 blog posts):

• Compute (CPU/Memory):
  Light traffic like yours will use minimal resources.
  Estimated Cost: ~$2–4/month

• Egress (Bandwidth):
  100 visitors/day × 30 days = 3,000 visits
  Average page size ~2–3 MB (with images)
  Total: ~6–9 GB/month
  Estimated Cost: 0.60–0.90/month (at 0.10/GB)

• Storage (Volumes):
  WordPress files, database, and images
  Estimated: ~5–10 GB
  Estimated Cost: ~$0.10–0.20/month

Please note that the actual cost may still vary depending on your usage. You can also configure Usage Limits to set a maximum limit for a billing cycle. If your resource usage exceeds that limit, workloads will be shut down to prevent further charges.

So maybe as a helper for the others, I have deployed it for one day and the MySQL was eating up to 453Mb RAM so it was totaling 891Mb RAM.

That would account to roughly:

Per minute: 0.891 GB × $0.000231 = $0.0002058

• Per hour: $0.0002058 × 60 = $0.01235

• Per day: $0.01235 × 24 = $0.296

• Per month (31 days): $0.296 × 31 = $9.18/month for memory alone

+ CPU + some Egress. For dummy site with few users..

I managed to lower the cost with some MySQL optimization and dedicating lower RAM to project in settings, will report after one month usage. But for such page and basic setup I believe somewhere around 5-6 USD would be optimal cost.

Will keep updated.
