A rate-up happens when the insurer asks for a higher premium on the term insurance plan that you have opted to buy. It is, sort of, like a revised offer from your insurer, because they have assessed your application and determined that there is a comparatively higher risk in providing you with a term plan because of your health, occupation, hobbies or financial status. Depending on the severity of your mental health conditions, your insurer may give you a term insurance plan with a rate-up. For e.g.: if you have a combination of nervous disorders, say depression and anxiety, you may get a rate-up.
