Amazon EC2 On-Demand Pricing: Instance Families, Regional Multipliers, and the Graviton Crossover (2026)
Quick summary: EC2 On-Demand is not one price — it is a matrix of family, size, OS, tenancy, and region. In us-east-1 (June 2026), a m7g.large Linux instance runs $0.0816/hr while a GPU g5.xlarge is $1.006/hr. Most bill surprises come from wrong family choice, not wrong size.

- 0816/hr while a GPU g5
- xlarge is $1
Table of Contents
On June 17, 2026, AWS lists more than 750 EC2 instance SKUs across general-purpose, compute-optimized, memory-optimized, storage-optimized, and accelerated families. The On-Demand rate card is the baseline every Savings Plan and Reserved Instance discount is measured against — and the line item most teams oversize because they copy the instance type from a three-year-old architecture diagram.
Amazon EC2 On-Demand pricing bills per instance-second (60-second minimum) by family, size, OS, and region. In us-east-1 (June 2026), Linux
m7g.largeis $0.0816/hr. Most waste is wrong family — not wrong discount instrument.
Engagement shape
A logistics SaaS (~$38k/mo AWS, 120 EC2 instances across dev/staging/prod) ran primarily on m5.xlarge because that was the 2022 default. Compute Optimizer (32-day lookback, June 2026) recommended m7g.large for 68% of instances — same memory, half the vCPU headroom still above p95 CPU. Modeled savings: $4,100/mo On-Demand before any Savings Plan. Migration took two sprint cycles; one legacy PDF renderer stayed on x86.

Family selection beats size selection
We recommend family first, size second: pick m vs c vs r from workload shape (balanced vs CPU-heavy vs memory-heavy), then right-size within the family using Compute Optimizer or CloudWatch p95 CPU/memory over 14 days.
| Mistake | Typical cost impact |
|---|---|
| GPU family for CPU-only API | 5–10× hourly rate |
r family for stateless API | 30–50% overspend |
| x86 when arm64-compatible | 20–40% missed savings |
| Single-AZ oversized staging | 100% waste on idle hours |
