Rate making or insurance pricing is the determination of rates
charged by insurance companies. The three basic rate making methods
are judgement rating, merit rating, manual rating. They are
explained as follows:
- Judgement rating- It is that method of premium rate making for
which evaluation is done individually for each exposure. The rate
is determined largely by the underwriter's judgement based upon
their subjective evaluation of that risk. These ratings rely
heavily on the experience, perception and talent of the underwriter
who makes the final evaluation.
- Manual rating- It is an insurance premium rate based on some
unit of insurance. It is based on average claims data for a big
number of groups. This data is then adjusted for specific groups
based on the group characteristics.
- Merit rating- A merit rating plan is used in several cases of
insurance but most commonly in personal auto. In this type of
rating the insured's premium varies up or down depending upon the
person's past record as a driver or operator of the vehicle. A high
rating can translate to a high premium.
