The monthly premium rate of every Bowtie's customer is set based on actuarial calculation with historical data and a number of factors which include but not limited to:

1. Bowtie's previous claims and renewal experience
2. Medical cost inflation and expected future medical cost
3. Any applicable benefit amendments

Of course, your monthly premium would also be affected by your ages, occupation (mostly for accident insurance) and health conditions when you apply for the policy.

Premium rate increases annually due to the insured's age and medical inflation. However, it will not be adjusted due to:

1. The insured's claim history
2. Illnesses diagnosed after the policy is in effect or changes in the insured's health
3. Other personal factors
