Of course! Let's dive into the fascinating world of Berkshire Hathaway's float. It's a cornerstone of Warren Buffett's investment philosophy, and understanding it is key to appreciating the company's unique business model.
The Power of "Float": Unpacking Berkshire Hathaway's Financial Engine
Have you ever wondered how an insurance company makes money? It's not just from collecting premiums. The real magic, in the case of Berkshire Hathaway, lies in a concept that Warren Buffett himself has championed: "float."
Float is essentially other people's money that an insurance company holds for a period of time between collecting premiums and paying out claims. It's a pool of capital that can be invested to generate returns, and for Berkshire, this has been an extraordinarily powerful engine for growth. It's like getting paid to hold and invest a massive sum of money.
Ready to find out just how much float Berkshire Hathaway has and how it's grown over the years? Let's break it down, step by step.

Step 1: Understanding the Concept of Float
Before we get to the numbers, let's make sure we're on the same page. Think about your own car insurance. You pay a premium every month or year, but you might not have an accident for a long time, or ever. The insurance company collects your money and the money from millions of other policyholders. This cash doesn't just sit in a vault. It's a liability on the balance sheet because it will eventually need to be paid out as claims.
Tip: Each paragraph has one main idea — find it.
However, in the interim, the insurance company has the use of that money. This is the float. As Warren Buffett himself has explained, while float is a liability from an accounting perspective, it's a valuable asset in practice.
A Low-Cost Source of Capital: When an insurance company is run well and achieves an "underwriting profit" (meaning the premiums it collects are greater than the claims it pays out and its operating expenses), that float is essentially a costless source of capital. It's a loan that costs you nothing. This is a huge advantage over taking on debt, which requires interest payments.
The Berkshire Difference: Most insurance companies invest their float conservatively, often in low-yielding bonds. Berkshire Hathaway, however, uses its float to make large-scale, long-term investments in a wide variety of businesses, both publicly traded and wholly owned. This is a fundamental difference in its business model and a major reason for its success.
Step 2: Locating the Float in Financial Reports
To find out the amount of float, you need to look at Berkshire Hathaway's financial reports, specifically the annual report (10-K) and quarterly reports (10-Q) that are filed with the SEC. These reports provide a detailed breakdown of the company's assets and liabilities.
The float is not a single line item, but rather a calculation derived from various liabilities on the balance sheet of its insurance subsidiaries. The main components of float are:
Unearned premiums: Premiums collected for coverage that has not yet been provided.
Loss and loss adjustment expense reserves: Money set aside to pay for future claims and the costs associated with settling those claims.
Life, annuity, and health benefit liabilities: Reserves for future payments on life and health insurance policies.
You would subtract certain assets, such as reinsurance and premium receivables, from these liabilities to get the net float. However, Berkshire Hathaway's reports often provide a consolidated "insurance float" figure, which makes it much easier to track.
Step 3: Tracking the Float’s Growth Over Time
QuickTip: Read a little, pause, then continue.
Now for the numbers you've been waiting for. Let's look at how Berkshire's float has grown, which is a testament to the success of its insurance operations.
At the end of 2019: The consolidated float was approximately $129 billion.
At the end of 2023: This had grown to approximately $165 billion.
At the end of 2024: The float reached an impressive $171 billion.
As of March 31, 2025 (Q1 2025): The float continued its upward trajectory, growing to approximately $173 billion.
This steady growth highlights the strength and scale of Berkshire's insurance businesses, which include giants like GEICO, General Re, and Berkshire Hathaway Primary Group. These companies consistently generate underwriting profits, which means they are not only growing the float but also earning a profit on their core business. This makes the float even more valuable as a costless funding source.

Step 4: The Impact of the Float on Berkshire's Business
So, what does Berkshire do with all this money? This is where the magic of Warren Buffett's capital allocation comes in. The float is deployed into various investments that generate significant returns for shareholders.
Sub-heading: Investing in a Diverse Portfolio
The float is a key source of capital that allows Berkshire to build its massive investment portfolio. This portfolio includes:
Publicly Traded Equities: Large stakes in companies like Apple, Coca-Cola, and American Express. These are not just passive investments; Buffett views them as partial ownership of great businesses.
Wholly Owned Subsidiaries: Acquiring entire companies, such as BNSF Railway and Berkshire Hathaway Energy, is a major use of the float. These are businesses with strong, durable earning power that generate significant cash flow.
Sub-heading: The Underwriting Profit Advantage

What sets Berkshire apart is its consistent ability to generate an underwriting profit. Over the past two decades, Berkshire's insurance business has generated billions in after-tax profits from underwriting. This is a crucial point that many people miss. It means that the float isn't just "free" money; it's money that the company is paid to hold and invest.
In 2024, Berkshire's re/insurance underwriting gain rose to a remarkable $9 billion, a 66% increase from the prior year. This phenomenal performance further solidifies the health of its insurance operations and its ability to continue growing the float.
Step 5: The Float's Role in Berkshire's Future
The growth of the float is a strong indicator of Berkshire Hathaway's enduring competitive advantage. As long as the company can continue to grow its insurance business and underwrite policies profitably, the float will likely continue to grow. This provides a steady, low-cost source of capital that can be deployed to acquire new businesses, expand existing ones, and invest in a portfolio of world-class companies.
The float is not just a number on a balance sheet; it's a living, breathing testament to a business model that has generated immense wealth for shareholders for decades. It is a powerful engine that continues to fuel Berkshire's growth and value creation.
