What is life insurance & how does it work?

Life insurance provides financial protection for the people you care about. You pay a monthly or annual


to an insurance company, and in exchange the company pays a tax-free lump sum of money to your


if you die while the policy is active. You can customize your life insurance policy to fit your family’s needs by choosing the type of policy you buy, the number of years you want it to last, and the amount of money paid out.

So what does life insurance cover? Your beneficiaries can use it to cover many types of expenses, including:

  • Co-signed debt, including student loans

  • Mortgages

  • College expenses for your kids

  • Living expenses for your family

  • Home labor expenses (cooking, cleaning, etc.)

  • Burial expenses

  • Estate taxes that your heirs must pay for other assets

  • Medical expenses

  • Charitable contributions

To get this money after you die, your beneficiaries will fill out a death claim form and submit it to the insurer. Once the insurer approves the claim, your beneficiaries get the funds to use however they want.

How does term life insurance work?

Term life insurance provides the most straightforward coverage. It's active for a set period, usually 10 to 30 years, and pays out a death benefit to your beneficiaries if you die while the policy is active. That's it — no frills, just simple financial protection for the people you care about. Term is the most common type of life insurance.

How does whole life insurance work?

Like term life, whole life insurance pays out to your beneficiaries when you die, but it has more bells and whistles. For starters, it’s active for your entire life, so your beneficiaries are guaranteed to get a death benefit. It also comes with a savings component called the cash value, which can be used to supplement your nest egg and diversify your investment portfolio.

How do other types of insurance work?

Most people just need a straightforward term or whole life policy, but there are other types out there, too. Most of these policies are catered towards niche financial planning needs, such as a specific investment plan or people who can't get traditional coverage.

What’s in a life insurance policy?

To fully understand your life insurance policy, there are a few terms you need to know. No matter what type of policy you buy, life insurance consists of these five components:

bold orange check

The person covered by the policy. When they die, the life insurance company pays out the death benefit.

bold orange check

The person who owns the life insurance policy and pays the premiums to keep it active. Usually the policyholder and the insured are the same person, but occasionally they are different.

bold orange check

The person, people, or institution(s) that receive money if the insured dies. There can be more than one beneficiary named on the policy.

bold orange check

The money paid monthly or annually to keep a policy active (or “in force”). If you stop paying premiums, your policy will be canceled by the insurer.

Death benefit

The amount of money paid out upon the death of the insured. Life insurance becomes active as soon as the first premium is paid, so policy beneficiaries can receive the death benefit right away.

Why is life insurance important?

Most Americans don’t have enough emergency savings to last three months, [1] let alone enough to cover their family’s expenses for years to come. That’s where life insurance comes in — you can protect your family even if you don’t have $1 million in the bank. Life insurance provides a contingency plan for as little as $20 to $30 a month, and ensures your family isn’t left scrambling for funds after you’re gone.

What are the benefits of life insurance?

Is life insurance a good investment?

If you're a high-earner who has maxed out your investments, you can add whole life insurance to your portfolio. But for most people, it's an insurance product first and foremost.

Who needs life insurance?

Anyone with financial obligations should get a policy. Life insurance does more than just provide money for everyday living expenses. It can pay for estate taxes, provide money for college, cover outstanding debts, build generational wealth, and pay for your funeral (which can cost upward of $7,000).

People who need life insurance include:

  • Income-earning parents: Parents provide financial support for their kids, paying for things like food, housing, and college tuition.

  • Stay-at-home parents: Stay-at-home parents care for children, clean, cook, and do other work that would cost money to replace.

  • Spouses or domestic partners: If you share expenses, having a life insurance policy ensures your partner won't be liable for double what they can afford.

  • Students with co-signed student loans: If you die, any unpaid debts fall to the co-signer.

  • People with a mortgage: Life insurance can cover your mortgage payments so your family doesn't lose their home.

  • Caregivers: Leaving behind a life insurance policy ensures that your family will be able to afford continued care.

  • High-net-worth individuals: If your family would be on the hook for estate taxes after you die, they can use the life insurance money to cover those taxes.

How much life insurance do I need?

When you buy a policy, you’ll need to decide on a coverage amount — how much your beneficiaries will receive as a death benefit. As a general rule, our experts recommend you get about 10 to 30 times your income in coverage.

To calculate a more precise figure, you can use the DIME method, which tallies up your outstanding Debt, annual Income for the number of years that you'll provide for your family, the amount left on your Mortgage, and the cost of your children's Education. That number is a good starting point, but you may need less or more depending on personal factors such as other savings or whether you're supporting older family members.

How much does life insurance cost?

How much you pay for life insurance depends on your health profile and how much coverage you’re buying. A healthy adult in their 30s can expect to pay under $30 a month for a $500,000 policy that lasts 20 years. Buying life insurance does get more expensive as you get older, but there’s always a way to get coverage that fits into your budget.

Getting life insurance as soon as possible is the best way to get the most affordable policy. It also protects you from any health changes that could increase your rates. Other factors, like working in a dangerous occupation, having serious medical conditions that run in your family, or smoking, can impact your rates, too. A Policygenius agent can advocate on your behalf to get you the best rates for your profile.
