How much does Route 53 cost?

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.

Is there a free DNS option?

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.

What is a DNS hosted zone?

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.

How many DNS queries does a typical website generate?

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.

Do DNS costs include domain registration?

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.

How does TTL affect DNS cost?

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.

About the DNS Query Cost Calculator

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.

When This Page Helps

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.

How to Use the Inputs

Enter the number of DNS hosted zones you manage.
Set the per-zone monthly rate (e.g., $0.50 for Route 53).
Enter your total monthly DNS queries in millions.
Set the per-million-query rate (e.g., $0.40 for Route 53).
Review the total monthly cost breakdown.

Formula used

Zone Cost = zones × per_zone_rate
Query Cost = queries_millions × per_million_rate
Total Monthly = Zone Cost + Query Cost

Example Calculation

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.

Tips & Best Practices

Increase DNS TTL values to reduce query volume; 300–900 seconds is a good balance.
Consolidate subdomains into fewer hosted zones using wildcard records where possible.
Route 53 health checks cost $0.50–$1.00/month each; audit for unused health checks.
Use alias records (Route 53) or CNAME flattening to avoid unnecessary lookups.
Consider Cloudflare DNS for free DNS hosting with unlimited queries.
Monitor query analytics to identify and block abusive bot traffic inflating query counts.

DNS Provider Pricing Comparison

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.

Reducing DNS Query Costs

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.

When DNS Gets Expensive

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.
