Prince Charles is worth up to $400 million thanks to assets like a medieval estate implicated in the Paradise Papers and an infamous prison - take a look at how he spends his fortune

• Prince Charles's net worth is estimated between $100 million and $400 million.
• Most of his wealth stems from a medieval estate known as the Duchy of Cornwall.
• The estate consists of valuable land, commercial and residential property, financial assets, and even a prison.

Prince Charles's net worth is high enough to provide the longtime heir to the British throne with a kingly existence.

Estimates about how much money the heir apparent has got in the bank tend to fall in the hundreds of millions. Go Banking Rates reported that he has $100 million. Other estimates, however, are considerably higher. According to Time and Town and Country, he's worth around $400 million. Regardless of how many millions of dollars is currently under the prince's name, it's likely that not all of that money is constantly available to him.

Much of Prince Charles's income derives from the Duchy of Cornwall. As the longest-serving Duke of Cornwall, he's entitled to the private estate's annual revenue surplus.

According to the duchy's most recent financial statement, the revenue "does not cover official travel or property services, which are funded by the sovereign grant." British taxpayers support the royal family through an annual sovereign grant.
