1. Use current inputs
Enter the basic pay, DA, service details and dates shown in your own records. Small input changes can affect the result.
2. Read the rule notes
Each tool includes scope and assumptions. Read them before using an estimate for a financial or service decision.
3. Confirm final figures
Official claims and payments depend on the applicable order and your service record. Confirm final figures with your DDO, PAO or establishment section.
