A catalog of 100 static configuration data items can cost $0 in parameter store standard or $40 per month in aws secrets manager, before a single application reads it. That gap makes secrets manager vs parameter store pricing a design decision, not a minor billing detail, especially when you evaluate each pricing model carefully.
The cheaper service isn’t always the lower-cost choice. Rotation, encryption keys, retrieval volume, and operational ownership can change the result. The figures below use AWS US East (N. Virginia), us-east-1, as the pricing reference for aws secrets manager and parameter store.
Key Takeaways
- The parameter store standard tier has no additional monthly charge for stored parameters or API requests at standard throughput.
- Aws secrets manager costs $0.40 per secret each month, plus $0.05 per 10,000 API calls for tasks like managing database credentials.
- Parameter store advanced costs $0.05 per parameter each month and can incur API charges when higher throughput is enabled.
- Aws secrets manager is usually worth its premium for managed secret rotation and purpose-built secret workflows.
- Lambda, aws kms, CloudTrail, PrivateLink, and database services can add separate charges.
Secrets Manager vs Parameter Store pricing at a glance
AWS prices aws secrets manager around the number of secrets stored and the number of api calls. In us-east-1, each secret costs $0.40 per month, prorated hourly, and api calls cost $0.05 per 10,000 calls. There are no setup fees or minimum commitment. AWS publishes the current rate card on its Secrets Manager pricing page.
Parameter store belongs to aws systems manager and has two tiers. Standard parameters in the standard tier carry no additional storage charge. They are a strong fit for non-sensitive application configuration, feature flags, endpoint names, and modest volumes of SecureString values.
Advanced parameters cost $0.05 per parameter per month, also prorated hourly. They are appropriate when a workload needs advanced policies, larger parameter values, or greater scale. API interactions are free at default throughput. If you enable higher throughput, AWS charges $0.05 per 10,000 API interactions.
| Cost element | Secrets Manager | Parameter Store Standard | Parameter Store Advanced |
|---|---|---|---|
| Monthly storage price | $0.40 per secret | No additional charge | $0.05 per parameter |
| API price at standard throughput | $0.05 per 10,000 calls | No additional charge | No additional charge |
| Higher-throughput API price | N/A, normal API rate applies | $0.05 per 10,000 interactions | $0.05 per 10,000 interactions |
| Automatic rotation workflow | Built in, usually Lambda-backed | Build it yourself | Build it yourself |
| Monthly charge after deletion mark | No charge | Depends on parameter deletion | Depends on parameter deletion |
The storage multiple is the first cost signal in the pricing model. A secret in aws secrets manager costs eight times as much as an advanced parameter, while a standard parameter has no added storage costs. Yet this comparison only holds when parameter store and aws secrets manager meet the same operational requirement.
Secrets Manager’s $0.40 fee buys a secret-focused control plane. Parameter Store’s lower price shifts rotation and some lifecycle work to your team.

Monthly cost examples for common AWS workloads
The following calculations use published us-east-1 list prices. They include only aws secrets manager or parameter store charges unless a row says otherwise.
Static configuration for a web application
A platform team stores 100 non-secret settings, such as service URLs, log levels, timeout values, and feature configuration data. The application makes 500,000 reads each month.
| Option | Storage calculation | API calculation | Estimated monthly service cost |
|---|---|---|---|
| Secrets Manager | 100 x $0.40 = $40.00 | 500,000 / 10,000 x $0.05 = $2.50 | $42.50 |
| Parameter Store Standard | $0.00 | $0.00 at standard throughput | $0.00 |
| Parameter Store Advanced | 100 x $0.05 = $5.00 | $0.00 at standard throughput | $5.00 |
For static configuration data, aws secrets manager adds $42.50 in monthly service charges without providing a direct pricing advantage. Parameter Store is usually the sensible default if its quotas and feature set fit the workload while helping you avoid api rate limits.
Application credentials with frequent retrieval
Consider 30 production credentials stored as aws secrets manager secrets. Ten Amazon ECS services retrieve each secret repeatedly, producing 2 million api calls per month.
Storage costs are 30 x $0.40, or $12.00. API costs are 2,000,000 / 10,000 x $0.05, or $10.00. The Secrets Manager total is $22.00 per month.
If the same 30 values lived in parameter store advanced with higher throughput enabled, storage costs would be $1.50 and the 2 million interactions would cost $10.00, for $11.50 per month. With standard throughput, the parameter store API portion would remain $0, making the direct service charge $1.50.
That calculation doesn’t make parameter store an equal replacement. Credentials may need rotation, version handling, resource policies, and a reliable recovery process. The Secrets Manager documentation details the service’s secret storage and retrieval model for database credentials and other sensitive values.
Database secrets that rotate automatically
Suppose an engineering team stores 15 database credentials in aws secrets manager and makes 100,000 retrieval calls each month. The baseline aws secrets manager bill is $6.00 for storage plus $0.50 for api calls, or $6.50 per month.
Automatic rotation is not included in that $6.50. A secret rotation function can add AWS Lambda request and duration charges, Amazon CloudWatch Logs charges, and possibly VPC networking costs when running a lambda function inside private subnets. The database itself, such as Amazon RDS or Amazon Aurora, remains billed separately. Secrets Manager doesn’t replace the database charge.
For a small rotation workload, these related costs may be low. However, teams should estimate them when rotations run often, functions run inside private subnets, or each rotation writes extensive logs.
Costs outside the two services that affect the total
A direct service price can hide the more meaningful part of the bill. Separate AWS charges deserve a line item in any comparison, especially when deploying workloads through infrastructure as code.
AWS KMS: Secrets Manager relies on an AWS-managed key, aws/secretsmanager, that avoids additional charges, while customer-managed keys for aws kms introduce monthly key fees and aws kms API request costs. Parameter Store SecureString values also depend on aws kms encryption, so retrieval frequency matters when managing secure parameters or configuring cross-account access.
AWS Lambda: Secrets Manager commonly uses a lambda function for automatic rotation, and while Parameter Store has no equivalent managed feature, teams frequently build a lambda function and an Amazon EventBridge schedule for custom rotation. When handling database credentials, executing a lambda function adds compute costs, and cross-account access can complicate network configurations.
AWS CloudTrail: CloudTrail records activity for these services, and tracking usage via cloudtrail helps satisfy compliance requirements and strict audit standards. Charges depend on how the account configures trails, data-event logging, Lake, and retention, though configuring cloudtrail to monitor secret retrieval should only factor into the budget if the design creates an incremental expense.
Database rotation targets: Rotating an Amazon RDS, Aurora, Redshift, or self-managed database credential does not remove core database costs. A custom rotation routine may also create database connections, fail during maintenance windows, or require network access to a private target to satisfy compliance requirements.
New AWS customers may have up to $200 in eligible AWS free tier credits under the program introduced in July 2025. Credits can reduce an initial bill, but they do not create a permanent secrets manager free tier. Parameter Store Standard’s no-additional-charge model is different and remains useful after promotional credits end.
Choosing the lower-cost service that still fits
Use the parameter store standard tier for application configuration data that doesn’t need automated credential rotation. It works well for environment-specific settings and many SecureString values when standard throughput and parameter limits are sufficient.
Choose parameter store advanced parameters when you need its advanced parameter capabilities but don’t need aws secrets manager’s rotation workflow. At $0.05 per parameter, it remains far cheaper for large configuration data inventories.
Choose aws secrets manager for database credentials that must rotate on a schedule, especially when you want native secret lifecycle governance. The monthly premium is easy to justify when it removes custom automation, failure handling, and secret lifecycle work.
Retrieval patterns also matter. An application that requests a secret on every transaction can turn aws secrets manager api calls into a material line item. Cache credentials in memory where security requirements permit, refresh them on a controlled schedule, and avoid placing a parameter store lookup on a high-volume request path to minimize api calls.
Frequently Asked Questions
Is Parameter Store always cheaper than AWS Secrets Manager?
Parameter Store Standard is typically free for storage and standard throughput, making it much cheaper for basic configuration data. However, if you need built-in secret rotation and advanced lifecycle management, Secrets Manager justifies its higher monthly fee by saving engineering time.
Can Parameter Store automatically rotate database credentials?
No, Parameter Store does not include native automated rotation workflows out of the box. Teams must build and maintain custom AWS Lambda functions and Amazon EventBridge schedules to achieve automatic rotation.
Do I incur extra charges when using AWS KMS with these services?
AWS Secrets Manager uses a default service-managed key without extra monthly charges, but using customer-managed KMS keys introduces per-key fees and API request costs. Parameter Store SecureString parameters also rely on KMS encryption, which can impact your total bill depending on retrieval volume and configuration.
Final Cost Decision
When analyzing secrets manager vs parameter store pricing, Parameter Store standard tier wins on direct cost for ordinary configuration. Parameter Store Advanced remains inexpensive when its extra controls are required.
Aws secrets manager costs more because its pricing model is built for secret lifecycle management, especially automated secret rotation. Price aws secrets manager alongside KMS, Lambda, logging, and database dependencies, then choose the option that leaves your team with the smallest reliable operating burden.
