Operating Margin
29.2%
Gross margin is not shown for a lender or insurer: its revenue is interest, premiums and fees rather than the sale of goods, so there is no cost of goods sold to measure it against.
Operating Margin = Operating Income / Revenue
Operating margin is the percentage of revenue remaining after operating expenses, reflecting operating efficiency.
