Estimate Your Amazon Bedrock Cost
Use this quick estimator for token-based model usage. Pick a model preset or enter custom rates, then click Calculate.
Note: rates are examples for planning. Always verify current AWS Bedrock pricing by model and region.
How this bedrock pricing calculator works
Amazon Bedrock billing usually depends on usage. For text generation, that means you are generally charged for input tokens and output tokens. This calculator gives you a practical estimate by combining:
- How many requests you send each month
- How large each prompt is (input tokens)
- How long each response is (output tokens)
- The model’s token rates
Because token counts can vary by workload, the calculator is best used for scenario planning: conservative case, expected case, and heavy usage case.
The core formula
Monthly token totals
Total input tokens = Monthly requests × Average input tokens per request
Total output tokens = Monthly requests × Average output tokens per request
Monthly cost
Input cost = (Total input tokens ÷ 1,000,000) × Input rate
Output cost = (Total output tokens ÷ 1,000,000) × Output rate
Total monthly estimate = Input cost + Output cost
Why estimates can differ from your final bill
Even a good calculator is still an estimate. Actual charges can differ due to operational details like request retries, model changes, region differences, guardrails usage, or additional AWS services used in the same solution.
- Model choice: each model family has different input/output pricing.
- Prompt engineering: longer system prompts increase input tokens quickly.
- Response length: uncapped outputs can dominate total cost.
- Traffic bursts: peaks often increase monthly totals more than averages suggest.
Practical cost-control tips
1) Control output length
Set a sensible max output token cap for every endpoint. This is often the fastest way to reduce spend without hurting quality.
2) Trim prompt overhead
Audit your system and template prompts. Removing repeated boilerplate and unnecessary examples can save a large amount at scale.
3) Route by task complexity
Not every request needs your most expensive model. Use a lightweight model for simple classification or extraction, and reserve premium models for complex reasoning.
4) Track unit economics
Measure cost per successful user action (not just cost per request). This helps you optimize for business outcomes rather than raw token volume.
Example planning workflow
- Estimate monthly requests from product analytics.
- Sample 200–500 requests to estimate average input/output tokens.
- Run three scenarios in the calculator:
- Low usage (short prompts, short outputs)
- Expected usage
- High usage (peak traffic + long responses)
- Use the high scenario as your budget guardrail.
Frequently asked questions
Does this include every possible Bedrock charge?
No. This page focuses on token-based text inference estimates. Production deployments may include additional costs from surrounding AWS infrastructure and related services.
Can I use this for custom model pricing?
Yes. Select Custom pricing and type your own input/output rates per million tokens.
What token counts should I start with?
If you have no history, start with a realistic pilot sample. A simple rule is to overestimate output tokens by 20–30% in early budgeting.
Final note
This bedrock pricing calculator is designed for fast decision-making: model comparison, budget forecasting, and early architecture planning. Use it weekly while traffic patterns and prompts evolve, and pair it with real production metrics for the most accurate forecast.
