API Quantity per Batch Calculator — Single & Multi-Lot Allocation
- Purpose: This calculator determines the assay-corrected API quantity to be weighed for a batch and performs lot-wise allocation using FIFO, FEFO, or purity-based strategies, ensuring optimal utilization of available API lots with clear calculation traceability and printable documentation.
- Enter the Name of API / Material for identification and print records.
- Enter the Theoretical API Quantity per batch and select the appropriate Unit (mg / g / kg).
- Select Single Lot or Multiple Lots mode based on the number of API lots used per batch.
- Use Add Lot to enter Lot ID, Available Quantity, Unit, Assay (as-is %), and Expiry Date, then click Save.
- Choose the Allocation Strategy: FIFO, FEFO, Highest-Purity First, or Lowest-Purity First.
- Expiry Date is mandatory for all lots when using FEFO (First Expiry First Out) strategy.
- Select Display Unit and Display Decimals for on-screen and printed results.
- Click Calculate to obtain assay-corrected quantity to weigh and lot-wise allocation.
- If the Available Quantity is insufficient, the calculator displays shortage and the maximum achievable API.
- Use Show Detailed Calculation to view step-by-step allocation logic after calculation.
- Use Print / Save as PDF to generate a report. Always review the printed report for correctness before use.
