Insurance Terms Explained for Nigerians (Simple Guide)

What is Insurance & Why Terms Matter

Before diving into vocabulary, here is a quick reminder:

• Insurance is a contract. You (the insured/policyholder) pay money (called premium) to a company (the insurer). If something bad happens (insured event), the company helps you pay part or all of the cost, depending on your policy.

• Insurance policies are legal documents. They use specific words—terms—to define what is covered, what isn’t, how to claim, how much you get. If you misunderstand a term, you could be surprised when making a claim.

So, knowing the words helps you:

• Read your policy document well

• Pick the right policy for your needs

• Know what you will do if something happens

Who is Involved: Insured, Insurer, Policyholder, Beneficiary

These are basic people or “roles” in insurance.

Policyholder

• This is the person who buys the insurance and holds the policy. You are the policyholder if you pay the premium.

• You have the rights: to change the policy, pick beneficiaries, cancel, renew etc.

Insured / Assured

• Sometimes the same as policyholder, but not always.

• The ‘insured’ is the person or thing actually protected by insurance. For example: your car is insured; or your life is insured.

Insurer

• The insurance company. They promise to pay or provide benefit when a covered event happens.

Beneficiary

• For life insurance (or some other covers), the beneficiary is the person who will get the money or benefit if you die or something happens.

• You choose who the beneficiary is (spouse, child etc.)

Premium, Sum Insured, Coverage & Policy Terms

These are very common terms you will see a lot.

Premium

• Definition: The amount of money you pay to the insurer so that your policy stays active. You might pay monthly, quarterly, or yearly.

• Example: You buy health insurance; you agree to pay ₦25,000 yearly. That is your premium.

Sum Insured (or Insured Sum)

• Definition: The maximum amount the insurer agrees to pay for a loss under a policy.

• Example: If your car is insured for ₦2,000,000, that is the sum insured. If car theft happens, the insurer won’t pay more than that.

Coverage

• Definition: What is protected under the policy. The list of risks or events the insurer agrees to pay for.

• Example: A motor insurance policy might cover accidents, fire, theft; it might exclude flood or storm (if not included).

Policy Term (Duration)

• Definition: How long the policy stays in effect, e.g. one year, five years.

• Example: A life insurance policy might have a 20‑year term. After 20 years it ends (unless it is a “whole life” policy).

Deductible, Excess, Co‑Payment & Out‑of‑Pocket Costs

These terms define what you pay when making a claim, before insurer pays, or along with insurer.

Deductible (or Excess)

• Definition: The amount you must pay yourself before the insurer pays the rest.

• Example: If your policy has a deductible of ₦50,000, and you submit a claim of ₦500,000, you pay ₦50,000 first; insurer pays ₦450,000 (if the loss is covered).

Co‑Payment or Co‑Pay

• Definition: A percentage of cost you pay even after deductible. Sometimes used in health insurance.

• Example: Your hospital bill is ₦100,000; insurance covers 80%; you pay 20% (co‑pay) = ₦20,000.

 Out‑of‑Pocket Cost

• Definition: Any cost you must pay that insurance does not cover. Deductible, co‑pay, any portion beyond policy limit, or excluded things.

Excess

• Another term for deductible in many policies; sometimes used slightly differently, but largely the same idea.

Exclusions, Waiting Periods & Limitations

These are terms that define what is not covered, or when coverage begins.

Exclusions

• Definition: Events or losses that the insurer says they will not cover.

• Example: A health plan may exclude cosmetic surgery, or “pre‑existing conditions” may be excluded in first year.

• Before buying, always read exclusions.

Waiting Period

• Definition: Time at the start of a policy during which some or all benefits are not available.

• Example: After you buy health insurance, there may be 30 days waiting period for general illnesses; maybe 90 days for specific surgeries.

 Limitations / Sub‑Limits

• Definition: Smaller caps inside the policy. Even if overall sum insured is high, certain benefits have separate caps.

• Example: Your health policy might allow only ₦100,000 for maternity even if overall coverage is ₦1,000,000.

Riders, Add‑ons, Endorsements & Optional Benefits

Sometimes you want more than the basic policy. These terms describe extra bits you can add.

Rider (Add‑on)

• Definition: Extra benefit or protection you add onto the base policy for extra cost.

• Example: Critical illness rider, accidental death rider, theft protection, flood cover etc.

Endorsement

• Definition: A change made to the policy after you buy it. For example, you add more coverage or change beneficiary.

Optional Benefits

• Definition: Any benefit you choose to include or leave out. More optional stuff usually means higher premium.

Renewal, Termination & Grace Period

These terms are about how a policy continues or ends.

Renewal

• Definition: When your policy term ends, renewal means extending it for another term.

• Example: Your motor insurance covers you for one year. If you renew, it continues for another year, usually with new premium.

Termination / Cancellation

• Definition: When either you or insurer ends the policy before or at the end of term.

Grace Period

• Definition: Extra time after premium due date during which coverage is not cancelled yet even if you didn’t pay on time.

 Underwriting, Risk, Claim & Settlement Process

These are about how insurers decide what to charge you, what to do when something bad happens.

Underwriting

• Definition: Process insurer uses to assess your risk (age, health, driving record, location, value of what you insure) to decide whether to accept you, and how much premium to charge.

Risk

• Definition: The chance or possibility something bad happens (accident, sickness, theft etc.).

Claim

• Definition: When you tell insurer “something bad happened, I want you to pay under the policy.”

Claims Process / Settlement

• Definition: Steps you take to file claim (notify insurer, show documents, maybe police report, repair bills etc.), then insurer investigates, then pays what’s due.

Claim Payout Types: Indemnity, Replacement Cost, Actual Cash Value

These terms define how much insurer gives you.

Indemnity

• Definition: The insurer pays you enough to restore you to the financial position you were in before the loss—but not to make profit.

Replacement Cost

• Definition: To buy a new item of same kind at current cost.

• Example: If your TV is stolen, you get amount needed to buy new.

Actual Cash Value (ACV)

• Definition: Replacement cost minus depreciation (age, wear & tear).

• Example: A car that is 5 years old may be worth less now; insurer deducts depreciation.

 Policy Limit, Sub‑Limit, Aggregate Limit & Cap Amounts

These define how much insurer pays overall or per event.

Policy Limit (Limit of Liability)

• Definition: The maximum amount insurer will pay under that policy for a single event or per term.

 Sub‑Limit

• Definition: A limit on a specific part of the coverage (e.g. jewelry, special items) lower than the overall policy limit.

 Aggregate Limit

• Definition: Total amount insurer will pay in a year for all claims combined. Once that aggregate cap is reached, no further payout that year.

Cap Amount

• Similar to limit; maximum you’ll get for particular benefit.

Reinsurance, Ceding, Coinsurance & Shared Risk

These are more advanced terms but good to know how insurance companies manage risk.

Reinsurance

• Definition: Insurance for insurers. When insurer wants to reduce its risk, it transfers part of risk to another insurer (reinsurer).

Ceding

• Definition: What insurer gives to reinsurer (transfers risk).

Coinsurance

• Definition: When more than one insurer covers a risk, each paying a share. Or sometimes policyholder shares part.

How to Use These Terms When Choosing Insurance

Knowing the terms is good—it helps when you shop for insurance. Here’s how:

1. Read policy documents carefully: Look for premium, sum insured, what’s covered, exclusions, deductible etc.

2. Ask questions: If you don’t understand a term (e.g. what is “aggregate limit”, or “co‑payment”), ask your agent or insurer.

3. Compare policies not just price: Two policies with same premium may differ in deductible, exclusions, network, etc.

4. Use examples / simulate worst‑case: Suppose car is stolen, hospital bill high—what will you have to pay? What insurer will pay?

5. Check waiting periods and grace periods: They affect when you can use protection and what happens if you miss payment.

6. Know your rights: Under NAICOM / NHIA etc, if insurer doesn’t fulfill contract, you may complain or seek regulatory redress.

Conclusion

Insurance terms may seem confusing, but they matter. When you understand what words like premium, deductible, exclusions, sum insured mean, you are in control. Being smart about insurance protects you: your money, your health, your car, your home.

For Nigerian students and working people, simply go slow: read the policy, ask questions, compare, don’t pick just by price. Use these terms as your tool to make good choices. The right policy with clear terms gives you peace of mind.
