Route 53 Pricing Calculator

What Is Route 53 Pricing

Amazon Route 53 is AWS's highly available and scalable Domain Name System (DNS) web service. Route 53 pricing is based on three main components: hosted zones, DNS queries, and health checks. While individual costs are small, organizations managing hundreds of domains with millions of queries can accumulate significant monthly charges without careful planning.

This calculator estimates your Route 53 monthly costs based on the number of hosted zones, expected query volume, health check configurations, and domain registration needs.

Route 53 Cost Components

Health Check Types

Common Use Cases

• DNS architecture planning: Estimate costs before migrating DNS infrastructure to Route 53 from on-premises or another provider
• Multi-region deployment costing: Calculate the additional cost of latency-based or geolocation routing for globally distributed applications
• Health check optimization: Evaluate the cost of health check configurations and optimize check frequency and count
• Budget forecasting: Project monthly Route 53 costs for growing applications based on traffic projections and domain expansion plans
• Cost comparison: Compare Route 53 pricing against alternatives like Cloudflare DNS, Google Cloud DNS, or Azure DNS

Best Practices

1. Consolidate hosted zones — Each hosted zone costs $0.50/month. If you have many domains pointing to the same infrastructure, use fewer zones with more records rather than one zone per domain.
2. Use alias records for AWS resources — Alias queries to AWS resources (ELB, CloudFront, S3) are free. Always use alias records instead of CNAME records for AWS endpoints.
3. Right-size health checks — Basic HTTP checks at $0.50/month are sufficient for most endpoints. Use string matching ($1.00) only when simple availability checks are insufficient.
4. Monitor query volume — Unexpected DNS query spikes (from DDoS attacks, misconfigurations, or bot traffic) can increase costs. Set billing alerts for DNS query charges.
5. Evaluate DNSSEC necessity — At $0.75/month per zone, DNSSEC adds cost. Enable it for zones serving critical applications where DNS spoofing is a realistic threat.
