Where do insurance companies get all their money?

Insurance companies make money in several key ways:

Collecting Premiums

The primary way insurance companies generate revenue is by collecting premiums from policyholders in exchange for insurance coverage. The premium is essentially the policyholder’s payment for transferring the financial risk of potential losses to the insurer. The insurer pools these premiums together to pay out future claims.

Premiums are calculated based on the insured’s risk profile, which considers factors like age, gender, location, driving record, claims history, and more. Higher risk individuals pay higher premiums to compensate the insurer for taking on more risk.

Investing Premiums

Once premiums are collected, insurance companies invest them to generate investment income. Rather than keeping the money in cash or low-interest savings accounts, insurers invest in assets like:

  • Bonds
  • Stocks
  • Real estate
  • Private equity
  • Hedge funds

This provides insurers with a second significant revenue stream beyond premiums. Investment income allows insurers to pay claims even if premiums fall short in a given year.

Underwriting Profit

Insurers also generate underwriting profit, which is the amount premiums exceed claims and expenses over a given period:

Underwriting Profit = Premiums Earned – Claims/Losses – Underwriting Expenses

Insurers aim to set premiums high enough to cover expected claims and expenses, plus provide a buffer for profit. Profitable underwriting reduces reliance on investment income.


Many insurers purchase reinsurance, which is insurance for insurance companies. Reinsurance allows primary insurers to limit their risk exposure by ceding some policies and premiums to reinsurers.

Insurers can earn profit by charging policyholders more premiums than they pay to the reinsurer. Reinsurance also stabilizes earnings, as the reinsurer takes on some of the volatility from claims.

Fees and Other Income

Finally, insurers earn income from fees, policy surrenders, and other sources like:

  • Administrative fees
  • Commission income
  • Interest income
  • Income from non-insurance operations

While premiums and investments provide the bulk of revenue, these other income sources contribute to insurers’ bottom lines.

How Insurers Use the Money

Insurance companies utilize the money they take in to:

  • Pay out claims: The main use of insurance company funds is paying policyholder claims. This includes claims for property damage, liability payouts, health costs, death benefits, and more depending on the type of insurance.

  • Cover underwriting expenses: Insurers deduct commissions, operating costs, and other expenses before calculating underwriting profit. Some key expenses include employee salaries, agent commissions, technology, facilities, and marketing.

  • Pay dividends to shareholders: Most insurers are public companies obligated to provide returns to shareholders. Profits may be paid out in the form of share price appreciation or dividends.

  • Contribute to reserves: Insurers maintain reserve funds to pay future claims and remain solvent. Money is set aside to cover claims that have been incurred but not yet reported or settled. Reserves also allow insurers to continue paying claims even when losses exceed premiums collected.

  • Invest in growth: Remaining funds can be used to invest in expanding insurance operations, developing new products, hiring talent, upgrading technology, and acquiring competitors. These investments allow companies to attract more customers and enter new insurance markets over time.

Challenges for Insurers

While this business model has worked well historically, insurance companies face increasing challenges:

  • Low interest rates make it harder to profit from investing premiums.
  • More frequent natural disasters drive up unpredictable claim costs.
  • Innovation from insurtech startups threatens to disrupt incumbents.
  • Pandemics and global crises create widespread losses.

To adapt, many insurers are updating their offerings, processes, and technology to operate more efficiently. They are also focusing more on profitable market segments and utilizing advanced analytics to improve pricing and underwriting.

While the core model remains unchanged, insurers must evolve to sustain adequate profitability. Their financial success hinges on calculating premiums accurately, managing claims effectively, and investing premiums prudently in an ever-changing environment.
