How Purchase Analyzer Works
Purchase Analyzer is based on the concept of analyzing eligible cloud usage over time and estimating how it would be covered by Savings Plans.
It allows you to:
Evaluate how much of your usage can be covered by a Savings Plan
Estimate potential savings based on different commitment levels
Analyze usage trends over a selected period
Compare different plan durations (1-year and 3-year)
The analysis is based on:
Your historical usage (lookback period)
Selected accounts (master or linked)
Existing commitments (optional exclusion)
Savings Plan Types
Compute Savings Plan
Covers compute services such as:
EC2
Fargate
Lambda
Applies across regions and instance types and suitable for general compute workloads
Database Savings Plan
Covers AWS managed database services, including:
Amazon RDS
Amazon Aurora
Amazon DynamoDB
Amazon ElastiCache
Amazon DocumentDB
Amazon Neptune
Amazon Keyspaces (for Apache Cassandra)
Amazon Timestream
AWS Database Migration Service (DMS)
Suitable for database workloads

Note: Database Savings Plans support only the No upfront payment option and are available for a 1-year term only.
How to Use Purchase Analyzer
Step 1. Open Purchase Analyzer
Navigate to Reservation tab
Open the Purchase Analyzer tab
Step 2. Configure Analysis Settings
Set up your analysis parameters:
Analysis Level:
Master account – includes all linked accounts (Available when the corresponding master account is added to Uniskai.)
Linked account – analyze selected accounts only
Management Account
Select the management account used for analysis
Linked Accounts
Select one or multiple accounts
Payment Option
Compute Savings Plans: No Upfront, Partial Upfront, and All Upfront options.
Database Savings Plan supports No Upfront only.
Lookback Period
Usage period: 7, 30, 60, or 90 days. Defines the time range used for analysis
You can exclude existing commitments from the analysis:
Unisave Commitments – commitments created and managed within the Uniskai platform
Reseller Commitments – commitments purchased through a reseller
When selected, these commitments will not be included in the analysis.
Step 3. Run Analysis
Click on the Run analysis button.
Step 4. Analysis Progress
The system processes analysis in stages:
In Queue – waiting for resources
Analyzing Data – calculating savings scenarios
Completing – preparing results
Step 5. Review Results
After completion, the system provides:
Recommended Commitment
Suggested hourly commitment
Calculated for:
1-year plan
3-year plan
Recommended Commitment:
Suggested hourly commitment for 1-year and 3-year plans.
Savings Estimation:
Estimated monthly savings and percentage improvement comparing current vs. recommended costs.
Cost Breakdown:
Compares commitment, on-demand, and total costs.
Usage Visualization:

Key Considerations
This analysis encompasses both a 1-year and a 3-year timeframe, presenting both scenarios within a unified evaluation.
The results presented are specifically tailored to the filters you have selected and the usage period you have specified, ensuring the analysis is relevant to your particular needs.
Flexibility is a key feature: You retain the ability to modify the parameters used in the analysis and rerun the evaluation at any point, allowing for iterative exploration and refinement of your optimization strategies.
Analysis Outcome
By leveraging the Purchase Analyzer, you gain the capacity to:
Develop a comprehensive understanding of your cloud usage patterns, identifying trends and areas for potential optimization.
Thoroughly evaluate various Savings Plans scenarios to determine the most advantageous options for your specific usage profile.
Compare different commitment options side-by-side, enabling you to weigh the trade-offs between flexibility and cost savings.
Ultimately, make well-informed cost optimization decisions, driving efficiency and maximizing the value of your cloud investments.
