Calculate DNS hosting costs based on hosted zones and query volume. Estimate Route 53, Cloud DNS, or Azure DNS monthly fees for your domains.
DNS is one of the most affordable yet essential infrastructure services. Managed DNS providers like AWS Route 53, Google Cloud DNS, and Azure DNS charge based on the number of hosted zones and the volume of DNS queries. Costs are typically a few dollars per month for most websites, but can add up for high-traffic domains or those with many subdomains.
Route 53 charges $0.50/month per hosted zone and $0.40 per million queries for the first billion. Google Cloud DNS charges $0.20/zone/month and $0.40/million queries. Azure DNS charges $0.50/zone for the first 25 zones and $0.40/million queries.
This calculator helps you estimate the total monthly cost of DNS hosting based on your number of zones and expected query volume. For most small to medium sites, DNS costs are under $5/month, but sites with hundreds of zones or billions of queries may spend significantly more.
This analytical approach supports proactive infrastructure management, helping teams avoid costly outages and maintain the service levels that users and business stakeholders depend on.
While DNS is inexpensive, costs multiply quickly when managing hundreds of domains or serving billions of queries. Understanding the per-zone and per-query pricing helps you optimize by consolidating zones, setting appropriate TTLs, and choosing the right provider based on your scale. Having accurate metrics readily available streamlines incident postmortems, architecture reviews, and technology roadmap discussions with engineering leadership and product teams.
Zone Cost = zones × per_zone_rate Query Cost = queries_millions × per_million_rate Total Monthly = Zone Cost + Query Cost
Result: $6.50/month
5 hosted zones at $0.50 each cost $2.50/month. 10 million queries at $0.40/million cost $4.00/month. Total: $6.50/month. This is a typical cost for a medium-sized business with several domains and moderate traffic.
Route 53: $0.50/zone + $0.40/M queries. Cloud DNS: $0.20/zone + $0.40/M queries (first 10K queries/zone free). Azure DNS: $0.50/zone (first 25), $0.40/M queries. Cloudflare: free for unlimited zones and queries. For pure cost, Cloudflare wins. For AWS integration and features (health checks, failover, latency-based routing), Route 53 is the standard choice.
The most effective strategy is increasing TTL values. For static sites, set TTL to 3600–86400 seconds. For APIs with blue-green deploys, use 60–300 seconds. Enable DNSSEC at no extra charge (Route 53 includes it). Use alias records to avoid extra CNAME lookups.
DNS costs only become significant at very large scale: 1,000+ zones ($500/mo in Route 53 zone fees) or 1B+ queries/month ($400+ in query fees). At that scale, consider dedicated DNS infrastructure or negotiate enterprise pricing.
Route 53 charges $0.50/month per hosted zone and $0.40 per million queries for the first billion queries, then $0.20/million for additional queries. Health checks are $0.50/month per endpoint (standard) or $0.75 for HTTPS checks.
Cloudflare offers free DNS hosting with unlimited queries, DNSSEC, and DDoS protection. Namecheap includes free DNS with domain registration. For AWS-centric setups, Route 53 costs are minimal but not free.
A hosted zone is a container for DNS records for a single domain. For example, example.com and its subdomains (www, api, mail) are all in one hosted zone. Each additional domain requires a separate hosted zone.
A site with 100K monthly visitors generates roughly 1–5 million DNS queries per month, depending on TTL settings and how many unique subdomains are in use. Heavy API-based architectures with short TTLs generate significantly more.
No. DNS hosting (serving records) is separate from domain registration (owning the name). Route 53 charges $12–$40/year per domain for registration, plus the separate hosted zone and query fees.
Higher TTL values mean resolvers cache records longer, reducing query volume. Changing from a 60-second TTL to a 3600-second TTL can reduce query volume by 60–80% for repeated visitors. The trade-off is slower propagation of DNS changes.
