How to Calculate Sum Assured and Premium for Life Insurance (2025 Guide)

• The right sum assured should cover long-term family expenses, outstanding liabilities and major future goals after deducting available assets and existing life cover.
• The insurer calculates premiums through underwriting, using the product design and the applicant’s disclosed risk profile rather than a universal formula.
• IRDAI’s current framework strengthens the Special Surrender Value methodology and requires the benefit illustration to show policy-year-wise surrender values.
• High-premium non-ULIP policies and ULIPs can lose maturity exemption under the applicable tax conditions, while qualifying death proceeds remain exempt.

Life insurance is a reliable way to secure the financial future of your family. In case of your demise, your family will receive the death benefit, which they can use for managing their expenses.

A useful policy decision begins with two separate questions: how much protection the family needs and what premium the household can continue paying without disrupting other essential goals. The first question determines the sum assured; the second helps narrow down the product, term and payment option.

IRDAI surrender value framework: The new rules specify a stronger Special Surrender Value methodology based on the expected present value of paid-up benefits, future benefits and accrued or vested benefits. The circular also requires policy-year-wise GSV, SSV and surrender values to be shown separately in the benefit illustration.

For eligible non-linked savings products, SSV becomes payable after the first policy year, provided that one full year’s premium has been received. The precise surrender amount remains product-specific and must be checked in the policy schedule and benefit illustration.

Tax treatment of high-premium non-ULIP policies: For non-ULIP life insurance policies issued on or after 1 April 2023, the maturity exemption is restricted when the annual premium, or aggregate premium across relevant policies, exceeds ₹5 lakh. The death benefit remains tax-free without conditions.

Tax treatment of high-premium ULIPs: For ULIPs issued on or after 1 February 2021, the exemption is restricted where the aggregate annual premium exceeds ₹2.5 lakh. Non-exempt gains are generally dealt with under capital-gains provisions.

For an equity-oriented ULIP, long-term capital gains exceeding ₹1.25 lakh are taxed at 12.5% while debt-oriented ULIPs attract tax at your slab rates.

The sum assured is the guaranteed amount that the beneficiary of your life insurance policy will receive in case of your death. The sum assured is also known as the coverage or the cover of your insurance policy.

There are many different ways to calculate the sum assured for your life insurance policy. One of the most popular methods is human life value, or HLV.

Human Life Value (HLV) Method

The Human Life Value method estimates the financial contribution that the family would lose if the earning member died. A practical version starts with annual income available for the family, projects it over the remaining working years and adjusts for expected income growth, inflation, personal expenses, taxes and the present value of future cash flows.

For illustration, a 35-year-old earning ₹10 lakh a year with 25 working years remaining has a simple, undiscounted income base of ₹2.5 crore before adjustments. A higher estimate, such as ₹3 crore or ₹3.5 crore, can arise only from the assumptions used for income growth and inflation; it is not an IRDAI-prescribed HLV value.

Income Replacement Method

The Income Replacement Method uses a multiple of annual take-home income as a quick starting point. A range of 10 to 15 times annual income is commonly used in personal-finance discussions, but no official Indian government source was found that prescribes this multiplier as a rule.

On that non-statutory basis, the annual take-home income of ₹10 lakh produces a preliminary range of ₹1 crore to ₹1.5 crore. This is only a screening calculation; it should be tested against loans, children’s goals, the spouse’s earning capacity, existing assets and the number of years for which income support is required.

Expense-Based Method

The Expense-Based Method is usually the most transparent because every component can be linked to a household obligation. Add outstanding loan balances, future education and marriage goals, dependants’ living expenses, emergency needs and any retirement corpus required for a non-earning spouse. Then subtract liquid investments, usable savings and existing life insurance cover.

As a general guideline, select the highest realistic result from the HLV, income-replacement, and expense-based methods. Avoid inflating the figure just to maximise cover, as the insurer may ask for financial evidence to support the sum assured.

The premium of a life insurance policy is a one-time or recurring expense that you pay for the policy. Your policy will only be valid until you pay the premiums as per the guidelines of the insurance provider.

Most insurance providers allow you to select the premium payment frequency from monthly, quarterly, half-yearly, yearly, or one-time payments.

The premium is not the same as the cost of insurance for every product. In a term plan, most of the payments support risk cover and expenses. In a ULIP, the payment is divided between insurance protection and investment units after applicable charges. In a traditional savings plan, the premium supports the guaranteed and non-guaranteed benefits stated in the benefit illustration.

The premium calculation depends on several factors. The insurance companies have an underwriting department that calculates the premiums. Every individual applying for a life insurance policy is required to go through this underwriting process.

Generally, younger and healthier individuals are required to pay a lower premium than someone in their 40s or 50s. Smokers and non-smokers are also quoted different premiums, as smokers are considered riskier.

Some of the most important factors that affect your life insurance premiums are

• Age at entry: Premium directly depends on the entry age. Older individuals tend to have higher premiums than younger ones because the mortality risk increases with age.
• Medical and family history: Existing medical conditions or family history of illnesses can increase the premium outgo because of enhanced health risks.
• Tobacco and nicotine use: Smokers or nicotine consumers are charged higher premiums because they are considered to have higher mortality risks than non-smokers.
• Occupation and activities: Work involving unusual physical risk, aviation, mining, offshore duties, armed services or hazardous hobbies may require additional premiums.
• Policy term and premium-payment term: Longer protection, limited-pay structures and payment frequency affect premiums. While long-term policy cover has a lower annual premium outgo, the overall premium paid might be higher than a short-term cover. Annual premium payments are cheaper than quarterly or half-yearly payments. Moreover, limited and single premiums are more expensive than regular premiums.
• Sum assured, and benefit design: A larger cover, a return-of-premium option, guaranteed additions, or savings benefits generally increase the premium.
• Riders: Accidental death, disability, critical illness, or waiver-of-premium riders add benefits and usually add cost.
• Gender: Insurers usually charge lower premiums from women compared to men.

Insurer quotations vary with product, underwriting, term, payment mode, riders, taxes and disclosed health information. Please check and compare the premium across insurers when buying a policy.

The maturity value is not automatically higher than the basic sum assured. It depends on the plan design, guaranteed benefits, declared bonuses or market-linked fund value. Likewise, surrender value is not simply a refund of premiums. The applicable policy-year value should be read from the signed benefit illustration and policy schedule.

Term insurance

Term insurance is primarily a risk-protection product. It normally provides a death benefit during the policy term and no maturity payment unless a return-of-premium feature is selected. Because it does not ordinarily build a savings value, it can provide a larger sum assured for a lower premium than savings-oriented products for the same person and term.

Endowment and other traditional savings plans

An endowment or money-back plan combines life cover with guaranteed or non-guaranteed savings benefits. Premium depends on the death cover, maturity benefit, guarantees, bonus structure, policy term and premium-payment term. Premiums are usually higher than term plans.

ULIP

A ULIP combines life cover with market-linked investment. The premium is allocated after applicable charges, including mortality and other policy charges disclosed in the product documents. The maturity value depends on units, fund performance, charges and withdrawals; it is not guaranteed merely because the product includes life insurance.

Under most ULIPs, you can decide the premium that you want to pay subject to the specified minimum and maximum limits.

• For policies issued on or after 1 April 2012, the eligible life-insurance premium deduction is generally restricted to 10% of the actual capital sum assured.
• For specified individuals with disabilities or specified diseases under policies issued on or after 1 April 2013, the corresponding limit is 15%.
• The overall deduction ceiling under the relevant life-insurance and savings provisions remains ₹1.5 lakh, subject to the taxpayer’s regime and other eligible investments.

For a non-ULIP policy issued on or after 1 April 2023, satisfying the premium-to-sum-assured ratio does not by itself guarantee tax-free maturity. When the annual premium or aggregate annual premium for relevant policies exceeds ₹5 lakh, the maturity exemption is restricted under the high-premium rule.

Where such a non-ULIP receipt is taxable, the amount chargeable under “Income from other sources” is broadly the receipt minus aggregate premiums paid that were not already claimed as a deduction elsewhere, subject to the statutory wording.

For a ULIP issued on or after 1 February 2021, the corresponding high-premium threshold is an aggregate annual premium above ₹2.5 lakh. When the exemption is unavailable, the gain is generally taxable as capital gains; qualifying equity-oriented ULIPs may fall under the special listed-equity capital-gains rules.

Amounts received on the death of the insured continue to receive the statutory exemption, subject to the policy and applicable law. The ₹5 lakh and ₹2.5 lakh caps discussed above apply to target maturity or other non-death receipts, not to qualifying death claims.

A bonus does not automatically increase the basic sum assured as written in the policy schedule. It may increase the total benefit payable under a participating traditional policy, depending on the type of bonus and the policy conditions.

• Reversionary bonus: An insurer may declare a bonus for a participating policy, commonly expressed as per ₹1,000 of sum assured. Once vested under the contract, it is added to the policy benefits according to the product terms.
• Terminal bonus: This is a one-time, non-guaranteed addition that may be payable on maturity or death when the insurer’s declared conditions are met.
• Guaranteed additions: Some products promise defined additions for specified years or subject to stated conditions. These are different from bonuses that depend on future declarations.

Bonus rates vary by insurer, product, policy year and declaration.

Illustration only: if a policy with a ₹10 lakh basic sum assured receives a reversionary bonus of ₹50 per ₹1,000 for each of 30 years, the simple accumulated bonus would be ₹15 lakh, and the combined amount would be ₹25 lakh before any other benefits or conditions.

Add Up One-Time Expenses

You must compute the family’s one-time expenses. These expenses can be outstanding debts, mortgages, personal loans, home loans, education loans, and credit card payments that can be paid in a lump sum.

Additional Of All The Assets

The next step is to calculate the total value of your assets. Remember, you add assets that your family is willing to offset with a lump-sum liability amount. These can be stocks, mutual funds, fixed deposits, provident funds, or automobiles. Also, property like house, land, gold/silver bars, high-valued jewellery, etc.

Do not automatically subtract every asset. A self-occupied home, essential vehicle, emergency reserve or family jewellery may not be realistically available to fund daily expenses. Count only assets that dependents could use without causing another financial problem.

Deduct Liabilities From Assets

Deduct the liabilities from the assets, and you will get the net assets available for your family to face a financial crunch, if any, to pay for funeral charges, accumulated rent charges, etc.

Deduct Assets From Liabilities

If the liabilities are more than the assets available, then you must consider that much amount of difference as the minimum sum assured so that there are no financial obligations on your family to tackle after you.

Calculate Annual Family Expenses

This is very crucial. To make sure that all the financial needs of your family are met after you, it is important to calculate the annual expenses of your family while calculating the sum assured. This includes grocery bills, electricity bills, school and college fees, other utility bills that need to be paid monthly, and multiply all by 12 to get the net annual expense.

Separate essential expenses from discretionary spending, then increase long-term estimates for inflation. Also deduct expenses that would stop after the insured’s death, such as personal travel or an individual loan that is separately insured.

Decide on the number of years you need to protect for

While deciding on the sum assured for a life insurance policy, you must consider the number of years for which you aim to provide your family with protection. Multiply your family’s annual expenses by that number and then add that to the net liabilities to get the approximate sum assured. If you feel that the decided sum assured won’t be sufficient, then you can raise the sum assured. However, you must be prepared to pay higher premium amounts for that.

1. List outstanding liabilities. Record the current outstanding balance of the home loan, car loan, education loan, personal loan and credit-card debt. Check whether any loan already has a separate insurance cover.
2. Estimate major future goals. Use current fee information and a reasonable inflation assumption for each child’s education or other essential goal.
3. Calculate family living expenses. Start with annual essential expenses and project them for the actual dependency period.
4. Add spouse's and dependent needs. Include a retirement corpus for a non-earning spouse, medical contingency and any lifelong support required for a dependant.
5. Subtract usable resources. Deduct liquid savings, investments that the family can genuinely use, employer-provided death benefits and existing life covers. Avoid deducting assets that the family must continue occupying or using.

Minimum protection needed = liabilities + future goals + family income requirement + dependant needs − usable assets − existing life cover.

Review the calculation after marriage, childbirth, a major loan, a substantial income change or a change in dependants.

To make the right decision, it is first essential to understand the product in detail, especially if it is something as important as life insurance.

A low premium is not enough to establish suitability. The policy must match the protection need, remain affordable for the full payment term and be based on complete disclosure. In a savings product, guaranteed and non-guaranteed benefits should be read separately. In a ULIP, it is important to understand market risk and charges. In a term plan, the death-benefit definition and exclusions deserve close attention.
