Investopedia explains 'Adjustable Premium'
An adjustable premium in the insurance industry is similar in structure to an adjustable-rate mortgage, because in both cases you can expect that the amount you need to pay will change. A policy that costs the insurance company more than they expect will cause adjustable premiums to increase; on the other hand, factors such as higher-than-expected investment returns on the part of the insurance company could cause the amount of the premiums to decline.
