Medical Insurance Companies: Making Money, Explained

how do medical insurance companies make money

Medical insurance companies make money by charging premiums in exchange for insurance coverage and then reinvesting those premiums into interest-generating assets. The passing of the Affordable Care Act (ACA) means that insurance companies are required to spend 80-85% of their income on claims and 15-20% on administrative costs. This has placed limitations on insurance companies but has also provided buffers in a less predictable marketplace.

Charging premiums for policies

Insurance companies make money in two main ways: charging premiums for policies and then investing the premiums into other assets and keeping the returns. The amount charged for premiums depends on the risk assumed by the insurance company. Actuaries are employed to predict this risk and calculate premiums accordingly. If an insurer charges too little for a premium, they may lose money if a claim is filed. Conversely, if they charge too much, they may lose prospective clients to the competition.

The premiums collected from customers are pooled and used to pay for claims when they are filed. The money that is not spent on claims or expenses is considered profit. Insurance companies invest a portion of their premiums to generate income. Rising market interest rates can boost earnings by providing insurance companies with a higher return on interest-bearing investments like Treasury bonds, high-grade corporate bonds, high-yield savings accounts, and certificates of deposit. Conversely, as rates fall, so does investment income.

In the United States, health insurance companies are heavily subsidized by taxpayers. For example, in 2023, UnitedHealth received 72% of its cash from tax dollars, totalling $1.8 trillion.

Investing premiums into other assets

Medical insurance companies make money by charging premiums for policies and then investing those premiums into other assets. This is their primary business model, and it involves two main steps. Firstly, they charge customers a premium, which is a monthly or annual fee for insurance coverage. Secondly, they take the money earned from premiums and invest it into interest-bearing assets, such as stocks, bonds, and real estate. The interest or returns generated from these investments contribute to the company's income.

The amount charged for premiums is based on the level of risk the insurer takes on. Actuaries calculate this risk using factors such as age, sex, and medical history to determine life expectancies and the likelihood of claims being filed. By diversifying their investments and pooling premiums, insurance companies can further minimise risk and maximise returns.

In the United States, the Affordable Care Act (ACA) or "Obamacare" has placed some restrictions on insurance companies. The ACA mandates that insurers spend 80% of premiums on claims and 20% on administrative costs. However, this has led to insurance companies increasing overall costs to maintain profit levels.

Underwriting income

> Underwriting Income = Premiums Collected – Claims Paid – Expenses

Insurance companies take the money that isn't spent on claims or expenses and invest it. The revenue model for insurance companies may vary among the different types of insurance, including auto, health, and property insurance.

Underwriting, in the context of insurance, is the process of evaluating an application for health insurance coverage by examining the applicant's medical history. The price of coverage is then determined by the risk factors of the applicant. The most comprehensive examination is referred to as full medical underwriting (FMU), which involves a detailed analysis of an individual's medical records. The process requires the health insurance applicant to provide a medical history going back several years, and the insurer may even contact the individual's healthcare providers for additional information.

In recent years, regulations such as the Affordable Care Act (Obamacare) have limited the use of medical underwriting in determining rates. While age, gender, and smoking habits may be considered, the act prohibits companies from denying coverage or setting higher rates based on pre-existing conditions.

Investment income

Insurance companies invest a portion of their premiums to generate income. They do this by pooling the premiums into interest-bearing investments. These investments can include stocks, bonds, real estate, Treasury bonds, high-grade corporate bonds, high-yield savings accounts, and certificates of deposit (CDs). Rising market interest rates can boost earnings by providing insurance companies with a higher return or yield on interest-bearing investments. Conversely, as rates fall, so too does investment income.

Actuaries play a crucial role in insurance companies by predicting risk and calculating the estimated costs of providing coverage. They use various factors such as age, sex, and medical history to determine how much different customers should pay in premiums. By charging premiums based on these calculations, insurance companies can ensure they have enough funds to cover potential claims and generate profit.

The business models of insurance companies tend to make them resilient during economic downturns, making them attractive investment opportunities. They are able to diversify risk by pooling risk from customers and redistributing it across a larger portfolio. Additionally, insurance companies do not invest in fixed assets, resulting in minimal depreciation and capital expenditures. As a result, insurance companies can provide solid long-term returns for investors.

Taxpayer subsidies

In 2023, federal subsidies for health insurance were estimated to be $1.8 trillion, with projections reaching $3.3 trillion by 2033. These subsidies are intended to make health insurance more affordable, particularly for individuals with lower or moderate incomes. The ACA's premium tax credit reduces monthly payments for insurance coverage, while the cost-sharing reduction (CSR) lowers deductibles and other out-of-pocket costs for eligible individuals.

The impact of these subsidies on patients and providers is a subject of debate. Some argue that insurers capture a significant portion of the subsidy payments, while others contend that the benefits are passed on to Medicare enrollees in the form of lower premiums and enhanced benefits. Research suggests that market power plays a crucial role in determining how gains from subsidies are distributed.

The ACA's subsidy structure also affects eligibility for Medicaid and Marketplace plans. In states that have expanded Medicaid, adults with incomes up to 138% of the Federal Poverty Level (FPL) are generally eligible for Medicaid instead of Marketplace subsidies. In non-expansion states, adults with incomes as low as 100% of the FPL may qualify for Marketplace subsidies, although those below 100% may face challenges in accessing tax credits or Medicaid.

Overall, taxpayer subsidies play a significant role in the business model of medical insurance companies, particularly in the context of the Affordable Care Act and its associated programs.
