What is insurance? Insurance is a contract that transfers specified financial risks from a person or organisation to an insurer in exchange for a premium. If an event covered by the policy happens and the policy conditions are met, the insurer pays a benefit or compensates an eligible loss as set out in the contract. Insurance does not cover every possible problem: the policy wording defines what is covered, what is excluded and how much can be paid.
Insurance works by pooling risk. Many policyholders pay premiums into a pool. The insurer uses that pool, together with its capital and reinsurance arrangements, to pay valid claims. The idea is that an individual or family does not have to bear the full financial impact of every covered event alone.
Quick notes: A premium is the price paid for cover. The sum insured or sum assured is the stated amount or limit, depending on the policy. An excess or deductible is the amount the policyholder must bear before certain benefits apply. A co-payment is a share of the eligible cost paid by the policyholder. Exclusions, waiting periods, limits and claim conditions matter as much as the headline benefit.
How insurance works
- Identify a financial risk: decide what loss would be difficult to pay for yourself, such as a major medical bill, loss of income, damage to a home or liability to another person.
- Choose a policy: compare the type of cover, insured event, benefit limits, exclusions, premium and insurer conditions.
- Apply and disclose information: answer the insurer’s questions accurately and provide required information. Incorrect or incomplete disclosure can affect a claim.
- Pay the premium: pay according to the schedule to keep the policy in force.
- Keep the documents: retain the policy wording, schedule, endorsements, receipts and renewal notices.
- Make a claim when an insured event occurs: notify the insurer, provide evidence and follow the stated claims process.
- Insurer assesses the claim: the insurer checks whether the event and loss meet the contract and then pays the eligible benefit or explains the decision.
The exact process differs between life, health and general insurance. A life policy may pay a stated sum after a covered event; a medical policy may reimburse or pay eligible hospital expenses; a motor policy may cover specified damage or liability. Never assume all insurance pays in the same way.
The main types of insurance
Life insurance
Life insurance provides a benefit when a covered event involving the insured person’s life or defined disability occurs. Term life insurance offers protection for a defined period. Whole-life products may provide lifelong cover and may include cash or investment features. Some policies provide benefits for total and permanent disability or other specified events. The details differ by product.
Health insurance
Health insurance helps pay eligible medical or healthcare costs, subject to the policy. In Singapore, examples include MediShield Life, Integrated Shield Plans, critical-illness cover, disability-income insurance and long-term-care protection. These products do not all pay the same type of benefit: some reimburse eligible bills, some pay a lump sum and others provide income or care benefits.
General insurance
General insurance covers specified risks affecting property, travel, vehicles, liability and other non-life interests. Examples include motor, home, travel, personal accident and work injury compensation insurance. The policy may pay for repair, replacement, an agreed benefit or liability costs within its terms.
Premium, sum insured, excess and exclusions
Premium: the amount paid to keep insurance cover in force. It may be paid monthly, quarterly, annually or as a single premium. Price can depend on the person’s risk profile, age, occupation, health, benefits, excess and policy design.
Sum insured or sum assured: the stated cover amount or benefit amount. The way it works depends on whether the policy is indemnity-based, agreed-value or benefit-based. A sum insured is not always the amount paid automatically after a claim.
Excess or deductible: the amount the policyholder must bear before certain claim payments are made. A policy with a higher excess may have a lower premium, but the policyholder needs to be able to afford the excess when a claim occurs.
Exclusion: a circumstance, condition, event or loss that the policy does not cover. Exclusions may apply to pre-existing conditions, particular activities, wear and tear, deliberate acts or other defined situations. Read the actual contract.
Waiting period and limit: some policies require a period to pass before particular benefits apply, and many impose per-claim, annual or lifetime limits. Sub-limits may apply to specific procedures, items or expenses.
How to compare two insurance policies
- Compare the coverage, not just the premium: identify exactly which events, people, assets and expenses are protected.
- Read exclusions and conditions: note pre-existing conditions, waiting periods, geographical limits, claim deadlines and evidence requirements.
- Check benefit limits: compare annual limits, per-event limits, sub-limits and whether benefits are paid as reimbursement or a fixed amount.
- Understand the excess or co-payment: calculate how much you would need to pay yourself during a claim.
- Check renewability and premium changes: understand whether the insurer can change premiums, terms or renewal conditions.
- Review overlap: check workplace benefits, existing policies and government schemes before buying duplicate cover.
- Confirm who is selling the policy: use authorised distribution channels and verify the representative when required.
A policy with a low premium can be unsuitable if its exclusions or limits do not match the risk you want to protect. Conversely, buying the largest possible cover is not automatically sensible if it is unaffordable or duplicates protection already available.
What is the difference between insurance and savings?
Savings keep money available for future spending. Insurance is designed to protect against specified financial losses or events. A savings account normally gives access to the money deposited, while an insurance policy pays according to its terms when a covered event occurs. Some products combine insurance with investment or savings features, but those products can be complex and may include fees, surrender conditions and investment risk.
Do not treat every insurance-linked investment product as a substitute for emergency savings. Understand the protection portion, investment portion, costs, surrender value, guarantees and risks separately.
What happens when you make an insurance claim?
The insurer assesses the claim against the policy wording, the facts of the event and the evidence provided. It may request medical reports, invoices, repair estimates, police reports, travel documents, photographs or other records depending on the product. It may also check whether premiums were paid, the policy was active and required disclosures were made.
A claim may be approved in full, approved in part, delayed while information is obtained or declined if the contract does not cover the event. A declined claim should be accompanied by an explanation referring to the relevant policy terms. Keep written records and ask the insurer how to appeal or complain if you disagree.
Insurance in Singapore: useful starting points
Singapore’s consumer-finance education portal MoneySense groups insurance into life, health and general insurance and explains how to assess needs. It emphasises that policies cover only what the contract says they cover. It also explains that some policies have a free-look period of at least 14 days after receipt of the policy document, with exceptions including travel, motor and maid insurance; check the current rules and the actual policy before relying on this.
For general insurance, MoneySense explains that motor, home, travel and other cover have different terms and that policyholders should understand what is and is not covered. For health insurance, deductibles, co-insurance and exclusions can materially affect out-of-pocket costs. In Singapore, the baseline protections available through public schemes also need to be considered before buying additional cover.

Common insurance mistakes
- Choosing only by price: a cheaper policy may have a higher excess, narrower cover or lower limits.
- Assuming every event is covered: the insured event, exclusions and claim conditions determine the result.
- Failing to disclose relevant information: inaccurate application answers can affect eligibility or a claim.
- Ignoring renewals: a policy may change its premium, benefits or conditions when renewed.
- Buying overlapping protection: multiple policies may not all pay the same type of benefit, and some costs may be duplicated.
- Missing claim deadlines: notification and documentation requirements can be time-sensitive.
