A
Actual Cash Value (ACV)
The value of your property at the time of a loss, taking depreciation into account. ACV payouts are lower than replacement cost payouts because they factor in age and wear. For example, a 10-year-old roof worth $5,000 today may have an ACV of $2,500.
Adjuster
A licensed professional — either employed by an insurer or hired independently — who investigates insurance claims, assesses damages, and recommends settlement amounts. Public adjusters work for policyholders; staff adjusters work for the insurance company.
B
Beneficiary
The person or entity designated to receive the death benefit from a life insurance policy. You can name multiple beneficiaries and specify percentage splits. Keeping beneficiary designations updated is critical after major life events like marriage or divorce.
Binder
A temporary, short-term insurance contract that provides coverage while a full policy is being processed. Binders are common in home and auto insurance and typically last 30–90 days.
Bundling
Purchasing multiple insurance policies (such as auto and home) from the same insurer to receive a multi-policy discount. Bundling discounts typically range from 5% to 25% depending on the carrier and state.
C
Cash Value
The savings or investment component that accumulates inside permanent life insurance policies (such as whole life or universal life). Policyholders can borrow against or withdraw cash value during their lifetime. Term life insurance has no cash value.
CLUE Report
Comprehensive Loss Underwriting Exchange report — a claims history database maintained by LexisNexis. Insurers use CLUE reports to review up to 7 years of a property's or driver's claims history when setting rates.
Coinsurance
In health insurance, the percentage of costs you pay after meeting your deductible. For example, an 80/20 plan means the insurer pays 80% and you pay 20%. In property insurance, coinsurance is a clause requiring you to insure your property to a minimum percentage of its value.
Collision Coverage
Auto insurance that pays to repair or replace your vehicle after a crash with another car or object, regardless of who is at fault. Collision coverage is optional in all states but is typically required by lenders when financing or leasing a vehicle.
Comprehensive Coverage
Auto insurance that covers vehicle damage from non-collision events including theft, fire, flooding, hail, vandalism, and animal strikes. Like collision, comprehensive is optional but often required by auto lenders.
Copay
A fixed dollar amount you pay for a covered health care service, regardless of the total cost. For example, a $30 copay means you pay $30 every time you see a primary care physician, while the insurer covers the rest.
D
Deductible
The amount you pay out of pocket before your insurance coverage kicks in. Higher deductibles mean lower premiums and vice versa. If you have a $1,000 deductible and file a $5,000 claim, you pay the first $1,000 and your insurer pays $4,000.
Declarations Page
The first page of an insurance policy — sometimes called the 'dec page' — that summarizes your coverage, policy limits, deductibles, premium, and the names of insured parties. It's the most important document in your policy to review annually.
Dwelling Coverage
The portion of a homeowners insurance policy (Coverage A) that pays to repair or rebuild the physical structure of your home after a covered loss. Dwelling coverage should reflect the full replacement cost to rebuild, not the market value of the home.
E
Endorsement
A written modification to an insurance policy that adds, removes, or changes coverage. Also called a rider. Common endorsements include scheduled personal property riders for jewelry or art, water backup coverage, and earthquake endorsements.
Exclusion
A specific loss, peril, condition, or circumstance listed in your policy that is NOT covered. Common homeowners exclusions include floods, earthquakes, and normal wear and tear. Reading your exclusions is as important as reading what's covered.
F
FAIR Plan
Fair Access to Insurance Requirements plan — state-mandated insurance programs that provide basic property insurance to homeowners who cannot find coverage in the standard market, typically due to wildfire, hurricane, or coastal risk. FAIR Plans are generally more expensive and offer less coverage than private policies.
G
Gap Insurance
Auto insurance that covers the difference ('gap') between what you owe on a financed or leased vehicle and its actual cash value at the time of a total loss. Essential for new cars that depreciate quickly in the first 1–3 years.
Grace Period
A specified timeframe after a premium due date during which a policyholder can make payment without losing coverage. Health insurance grace periods are typically 30 days for ACA marketplace plans; life insurance grace periods are usually 30–31 days.
Guaranteed Issue
An insurance policy that must be issued to an applicant regardless of health status, with no medical underwriting or exam required. Medicare supplement open enrollment periods offer guaranteed issue rights, meaning insurers cannot deny coverage or charge higher premiums based on pre-existing conditions.
H
HIPAA
Health Insurance Portability and Accountability Act — a 1996 federal law that protects patients' medical privacy, regulates health information security, and ensures workers can maintain health insurance coverage when changing jobs. HIPAA does not require any specific health plan to cover any particular service.
HMO (Health Maintenance Organization)
A type of health insurance plan that requires you to use a network of doctors and hospitals and get referrals from a primary care physician (PCP) before seeing specialists. HMOs typically have lower premiums but less flexibility than PPO plans.
I
Indemnity
The insurance principle of restoring an insured to their financial position before a loss — no better, no worse. Traditional health indemnity plans let you see any doctor and reimburse a set dollar amount per service regardless of the actual cost.
L
Liability Coverage
Insurance that pays for bodily injury and property damage you cause to others. Auto liability and homeowners liability are required by law or lenders in most states. Liability coverage protects your assets if you are sued.
Loss of Use
Homeowners or renters insurance coverage (Coverage D) that pays for temporary housing and additional living expenses if your home becomes uninhabitable due to a covered loss. This includes hotel bills, restaurant meals, and other costs above your normal expenses.
M
Medigap
Medicare supplement insurance sold by private companies to help cover costs that Original Medicare (Parts A and B) does not pay, including copays, coinsurance, and deductibles. Plans are standardized and labeled A through N. Also known as Medicare Supplement Insurance.
N
NAIC
National Association of Insurance Commissioners — a regulatory support organization for state insurance regulators. The NAIC develops model laws, maintains insurance data, and coordinates regulation across all 50 states. Their consumer complaint ratios are a useful tool for comparing insurers.
No-Fault Insurance
A system where each driver's insurance pays for their own injuries regardless of who caused the accident. Currently required in 12 states including Michigan, Florida, and New York. No-fault laws include Personal Injury Protection (PIP) requirements.
P
PIP (Personal Injury Protection)
A type of auto insurance coverage that pays for medical expenses, lost wages, and other injury-related costs for you and your passengers regardless of fault. PIP is required in no-fault states and optional in others.
PPO (Preferred Provider Organization)
A type of health insurance plan with a network of preferred providers. You can see out-of-network doctors at higher cost, and you don't need referrals to see specialists. PPOs offer more flexibility than HMOs but typically have higher premiums.
Premium
The amount you pay for insurance coverage — monthly, quarterly, semi-annually, or annually. Your premium is determined by underwriting factors such as age, location, claims history, credit score (in many states), and coverage limits.
R
Replacement Cost Value (RCV)
The cost to repair or replace damaged property with new materials of similar kind and quality at current prices, without any deduction for depreciation. RCV coverage is more expensive than ACV but provides much better protection after a major loss.
Rider
An optional add-on to an insurance policy that modifies or expands coverage, usually for an additional premium. Common life insurance riders include waiver of premium, accidental death benefit, and child term riders. Also called an endorsement in property insurance.
S
SR-22
A certificate of financial responsibility filed with your state's DMV by your auto insurer, proving you carry the minimum required liability coverage. SR-22s are typically required after a DUI, reckless driving conviction, or license suspension. An SR-22 itself is not insurance — it's a filing requirement.
Subrogation
The legal right of an insurance company to pursue a third party that caused an insurance loss to the insured. After paying a claim, your insurer 'steps into your shoes' and sues the at-fault party to recover what it paid out. Subrogation recoveries can sometimes reduce your deductible.
T
Term Life Insurance
Life insurance that provides a death benefit for a fixed period (term), typically 10, 20, or 30 years. If the insured dies during the term, the beneficiaries receive the death benefit. If the policy expires, there is no payout. Term life is the most affordable type of life insurance.
U
Umbrella Policy
A personal liability policy that provides additional coverage above and beyond the limits of your auto, home, or boat insurance. Umbrella policies typically start at $1 million in coverage and cost $150–$300 per year. They protect against large lawsuits that exceed your underlying policy limits.
Underwriting
The process insurers use to evaluate risk and decide whether to offer coverage, and at what price. Underwriters review factors like medical history, driving record, credit score, and property condition. Stricter underwriting guidelines have made coverage harder to obtain in high-risk states.
Uninsured/Underinsured Motorist (UM/UIM)
Auto insurance coverage that pays for your injuries and damages when the at-fault driver has no insurance or insufficient insurance to cover your losses. About 13% of US drivers are uninsured. UM/UIM coverage is required in many states and strongly recommended everywhere.
W
Waiting Period
A specified length of time after purchasing a policy before certain benefits become effective. Pet insurance waiting periods are typically 14 days for illnesses. Dental insurance may have 6–12 month waiting periods for major procedures. Life insurance has a contestability period of 2 years.
Whole Life Insurance
A type of permanent life insurance that provides coverage for your entire life as long as premiums are paid. Whole life builds cash value over time and has fixed premiums and a guaranteed death benefit. It costs 5–15 times more than comparable term life insurance.
