If the life assured survives the entire policy duration, the Guaranteed Maturity benefit is provided based on the following formula:
Guaranteed Maturity Benefit = Annualized premium * GMB Factor * (1+ High Premium Benefit, if any)
GMB Factor is calculated by taking various factors like entry age, PPT, PT and plan type (IMMEDIATE Income, DEFERRED Income & TWIN Income) into consideration.
GI1 under each plan of SUD Life Century Income policy is calculated and paid differently. In case of Immediate Income plan, it starts at the end of 1st Year Policy Year and continues till the end of policy period. It is constant every year and calculated as 10% of annualized premium. Under the Deferred Income plan, GI1 is accessible every year to the policyholder after the completion of the Premium payment term till the policy matures. Determined as a percentage of annualized premium, it starts with 30% of the annualized premium and gradually increases by 3% each year till the end of the policy. For example, in an insurance policy of PPT 7 years and policy duration of 15 years, it starts from the 8th year of the policy and reaches 51% of the yearly premium by the end of the 15th year. In case of the Twin Income plan, each GI1 is calculated as 105% of the annualized premium. It is disbursed to the policyholder at the end of consecutive policy years as per below table:
By opting for a higher premium, i.e. above ₹1 lakh, you’ll receive an added boost to your maturity benefit, which will increase by the percentages listed below: 
Yes, if you need to end the plan due to an emergency, you can surrender your policy after it has gained a Surrender Value. This usually happens after the first full policy year premium has been paid. When you surrender, you’ll receive a higher value between the Guaranteed Surrender Value (GSV) or Special Surrender Value (SSV).
Special Surrender Value will be acquired after the receipt of one full Policy Year premiums, whereas the Guaranteed Surrender Value will be acquired after the receipt of first two consecutive full Policy Year premiums.
If the life assured dies by suicide within 12 months from the date of commencement of risk or its revival date, the nominee will receive either 80% of the premiums paid up to the date of death or the available surrender value as on the date of death—whichever is higher—as long as the policy remains active.
