Inputs that matter
Use the most specific HTS code available and keep the product description close to the supplier invoice language.
Enter customs value, freight, and insurance consistently with the incoterm used in the quote.
Keep base duty, additional tariffs, MPF, HMF, and local charges as separate rows so the estimate can be audited.

Use the calculator to organize assumptions, then ask the broker to confirm the uncertain parts before shipment.
