If you buy insurance written on an original-value basis, the compensation paid in the event of a claim corresponds to the current market price. Home contents insurance is generally based on original value, which is why it is necessary to update the sum insured when you purchase new things. Some insurance companies adjust the sum insured to the development of certain indices, i.e. it is increased automatically from time to time. Some objects, such as skis, bicycles or sports gear, may not be insured at original value, but only at current value.
