For
insurance, the
loss ratio is the ratio of total losses incurred (paid and reserved) in claims plus adjustment expenses divided by the total premiums earned. For example, if an insurance company pays $60 in claims for every $100 in collected premiums, then its loss ratio is 60% with a profit ratio/gross margin of 40% or $40. Some portion of those 40 dollars must pay all operating costs (things such as
overhead and
payroll), and what is left is the
net profit. Loss ratios for
property and casualty insurance (e.g.
motor car insurance) typically range from 70% to 99%. Such companies are collecting premiums more than the amount paid in claims. Conversely, insurers that consistently experience high loss ratios may be in bad financial health. They may not be collecting enough premium to pay claims, expenses, and still make a reasonable profit. The terms "permissible", "target", "balance point", or "expected" loss ratio are used interchangeably to refer to the loss ratio necessary to fulfill the insurer's profitability goal. This ratio is 1 minus the expense ratio, where the expenses consist of general and administrative expenses, commissions and advertising expenses, profit and contingencies, and various other expenses. Expenses associated with insurance payouts ("losses") are sometimes considered as part of the loss ratio. When calculating a rate change, the insurer will typically divide the incurred or actual experienced loss ratio (AER) by the permissible loss ratio. == Banking loss ratio ==
