Bedrock AgentCore agent cost
Predict a Bedrock AgentCore agent bill: model tokens + Runtime + Memory + optional tools.
Use this when you're building an agent on Bedrock AgentCore and need to see how Runtime duration and long-term Memory stack on top of model spend.
Estimate your workload
Model choice is usually the biggest cost lever. Nova Micro/Lite are ~10–70× cheaper than Premier.
Active compute only — I/O wait is free, so this is usually below wall-clock latency.

- • Long-term Memory grows with retained user history — set a retention TTL or it becomes the #1 surprise on the bill.
- • AgentCore Runtime bills ACTIVE time only (I/O wait is free), so 'active seconds' is usually well below wall-clock latency.

Frequently asked questions
Why is 'active seconds' not the same as latency?+
AgentCore Runtime only bills while your code is actively using CPU/memory. Time spent waiting on the model or a tool (I/O wait) is free, so active time is typically 30–50% of wall-clock latency.
Why does long-term Memory get expensive?+
It's billed per 1,000 records retained per month and grows with user history unless you set a retention TTL. Unbounded Memory growth is the most common AgentCore bill surprise.
Do I need Gateway and Identity?+
Often no. Many agents call tools directly via Lambda and handle auth in API Gateway/Cognito, avoiding both AgentCore lines. They're off by default here.
