Float in Insurance: Meaning, How It Works, and Why It Matters

Key Takeaways
 

• Insurance float is the money a company collects from premiums and keeps until claims are paid, so it can use that cash for some time.
   
• Companies put this money into investments to earn extra income, which adds to their earnings along with what they make from selling policies.
   
• Float keeps building from unpaid claims and unused premiums, and if handled well, it reduces the need to borrow money and keeps finances stable. 

Bonus Tip: Berkshire Hathaway's insurance float hit about $176 billion by the end of 2025, up from just millions decades ago.

What happens to your premium money before any claim is made?

Riya works at an insurance company. One month, she saw many customers pay their premiums. But only a few claims came in that month. The money stays with the company for a while. Riya helped put that extra cash to work by investing it. This way the company earned some extra money before paying out claims. That cash is called a float. But what does float mean in insurance?

What is Float in Insurance Business?

Float is the cash an insurance company keeps after taking in premiums but before paying claims. Claims don't come right away. So the money stays put for some time. The company can invest it during that gap. This cash isn't the company's forever. It belongs to policyholders until claims get settled. People often call this pool insurance float. A well known case is float in insurance Berkshire Hathaway, where this money has grown very large over time.

How Float in Insurance Works?

Float moves in a simple cycle inside insurance work.

• Customers pay premiums for their policies.
   
• The company takes in and holds that money.
   
• Claims can show up later, sometimes months or years down the line.
   
• Until claims get paid, the company invests the cash.
   
• The gains from those investments turn into extra earnings.

Claims rarely come right after premiums arrive. So companies often hold big sums for a bit. This temporary cash is known as an insurance company float. They invest it until everything settles.

Importance of Float in Insurance

Float plays a key part in how insurance companies handle their money.

• It builds a steady pile of cash ready for investing.
   
• Earnings from those investments help the business grow.
   
• It evens out profits when claims shoot up.
   
• It cuts down on borrowing cash or hunting for outside funds.

Many companies handle all kinds of policies. This includes a floating policy in insurance. That kind covers goods or items that move from place to place. Premiums from those policies add to the company's float, too.

How to Calculate Float in Insurance?

Float shows up as a number on the balance sheet. It's not just a quick monthly subtraction. It tells the total cash held for policyholders at one point. In real life, people figure it using things like premiums taken in but not yet earned. Plus reserves set aside for claims coming later.

Formula: 

Float ≈ Unearned Premiums + Loss Reserves + Other Policyholder Liabilities − Premiums Receivable − Deferred Policy Costs

This math gives the net cash the company can invest until claims go out.

To make the idea easier, let's use Riya's case to see how to calculate float in insurance. This does not show the full float, but helps explain how float can grow.
