Gupta said the policies are going to get expensive, marginally. All policyholders will have to pay higher premiums on their insurance due to increase in GST rates.An average family with life, health and car insurances will find an increase of 3% in their insurance expenses. Assuming a family spends a total of Rs 30,000 per annum on insurance excluding service tax, their expenses will increase by 3%, i.e., Rs 900. Hence, it is not really a big increase and there is no cause for worry. If one is careful about choosing mutual funds and insurances and does the math beforehand, there should be no problems going forward.
