Calls compareAllCards with the Korean card table, minimum spend checks, benefit caps, annual fee subtraction, category-by-category benefit calculation, and optimal-card-combo search. This English finance calculator calls the same Korean pure calculation module as the Korean page. KRW amounts, Korean thresholds, insurance rules, tax logic, and scenario assumptions are preserved instead of the old generic percentage stub.
