The premium for the investment link is fixed upon inception of the policy meaning to say it will remain constant throughout the policy lifetime

However Cost of insurance might increase in the future which may require you to do some top up into your investment link policy in the future.

The investment gained by the insurance company is used to pay off future higher cost of insurance in an investment linked policy which is why it can remain as constant premium

Whereas a term insurance has no investment element which is why you are forking out a higher premium amount in the future because there is no investment cash value such as an investment link policy to cover your future cost of insurance.
