Friedhelm Loh Net Worth

Friedhelm Loh has an estimated net worth of $14.7 billion, according to Forbes Real-Time Billionaires, Friedhelm Loh profile (figures as of October 20, 2026). That is up from $6.8 billion in 2019.

Friedhelm Loh is a German businessman and the founder and chairman of the Friedhelm Loh Group. The group grew out of a company started by his father, Rudolf, in 1961. Rudolf created the first mass-produced enclosures for electrical control systems. Loh took over the business in 1974, renamed it Rittal, and built a larger industrial group around it. His companies now serve fields such as switchgear manufacturing, utilities, software, plastics, and sheet steel.

Much of Loh’s wealth comes from manufacturing. Rittal, the biggest company in his group, sells electrical enclosures, climate-control technology, power-distribution equipment, and IT infrastructure. The wider group also provides software, products, and services for complex electrical planning and industrial workflow. Forbes says the business has over 12,000 employees, 100 global subsidiaries, and annual revenue of around $3 billion. Loh also led the Association of the Electrical and Digital Industry from 2006 to 2014.

How Friedhelm Loh built his fortune

Loh’s fortune is tied to the Friedhelm Loh Group, which he developed from a family business. After taking charge in 1974, he turned Rittal into the core of a much broader manufacturing network. The group sells electrical enclosures, server cabinets, sheet steel products, plastic components, and software used for planning complex electrical systems. It also offers industrial workflow consulting, giving the business income from both products and services.

Rittal remains the key company. It supplies electrical enclosures, climate-control systems, power-distribution gear, and IT infrastructure to industrial customers. Forbes notes that the wider group serves industries including switchgear manufacturing and utilities. That scale matters. The business has over 12,000 employees and 100 subsidiaries around the world, with annual revenue of about $3 billion. Loh inherited the original business from his father, then expanded it into a large manufacturing group.

Forbes net worth and money milestones

Forbes has tracked Loh’s wealth rising sharply over time. On the Forbes World’s Billionaires List, he was estimated at $6.8 billion in 2019. By 2023, Forbes put him at $9.7 billion. The estimate then moved to $13 billion in 2025 and reached $15.5 billion on the 2026 billionaires list. Those changes followed the value Forbes assigned to his manufacturing holdings, led by Rittal and the rest of the Friedhelm Loh Group.

The current Forbes real-time estimate is lower than the annual 2026 list figure. As of October 20, 2026, Forbes’ real-time billionaires tracker put Loh at $14.7 billion. Outside the core business, Forbes also notes some of his other projects. In 2011, he committed $6.8 million to launch the Rittal Foundation, which backs educational, social, and scientific work. He also publishes religious literature through his Christian Media Foundation.
