AWS EC2 Spot pricing — indicative discounts vs On-Demand
How far Spot Instances sit below On-Demand, by family and region, from the same committed prices the AWS EC2 explorer uses. In us-east-1 the median discount is about62%, up to 77% on r7i.16xlarge. Spot is indicative — it fluctuates and can be reclaimed with a two-minute interruption notice. Free, no signup.
Spot prices are indicative & interruptible
Spot discount by family
Min / median / max indicative discount off On-Demand per family in us-east-1. Deeper is not better if the capacity is volatile — treat these as directional.

Spot is indicative and interruptible — read this first
- Not a guaranteed rate. Spot prices move continuously with supply and demand. The figures here are indicative percentages off On-Demand, updated on our nightly refresh — never a firm quote.
- Capacity can be reclaimed (interruption). AWS can reclaim Spot capacity with a two-minute warning whenever it needs it back for On-Demand demand. Spot suits fault-tolerant, checkpointable, or stateless work — batch, CI, rendering, big-data — not databases or long single-node jobs.
- Design for it. Use Spot for fault-tolerant, checkpointable, stateless, or horizontally scaled work. Keep a fallback to On-Demand for the parts that must not be interrupted.

List prices, directional. On-Demand rates are AWS EC2 public list prices in USD. Spot is indicative only — it fluctuates and capacity can be reclaimed with a two-minute interruption notice; never a firm quote. Always confirm in the console before relying on Spot. Prices as of 2026-08-26.
