Top Most Expensive Mistakes of All Time

Mistakes are a part of human life. Every Human makes mistakes in his life and learns from those mistakes and moves ahead. Humans are also said to be the ‘Statue of Mistakes’. But if we make mistakes related to money then it is not so easy to recover. Below we have discussed some of the expensive mistakes made by humans and wasted millions of dollars for every mistake.

Top Most Expensive Mistakes of All Time

1. Gold Mine for Sale

In 1867 Russia thought their land area had increased and it was difficult to control such a large area. So the government of Russia decided to sell 1.72 Million Square Kilometres to the USA for a price of 7.2 Million USD. But this was the biggest mistake made by Russia because today that land is called Alaska and has gold mines, natural gas and oil of a market value of around 200 Billion USD.

2. A Million Dollar Stock Market Typo

On 12 December 2005 a great person made a very good mistake. The J-Com company 1 stock price was around 610000 Yen (1 stock=610000 Yen). But a person in the Mizuho Company of Japan sold 610000 stocks in 1 Yen. How did he make such a great mistake, really unbelievable? Due to this mistake the company faced a huge loss of around 225 million USD.

3. The S.I. Unit Confusion

As we all know, there are fixed measurement units such as millimetres, centimetres, metres, kilometres, milligrammes, grammes, kilogrammes, litres, and more. However, British people use different measurement units known as English Units, such as feet, inches, pounds, wounces, and more. Nasa launched the Mars orbiter space mission in 1999, with directions to the satellite given in metres and kilometres, but Lockheed Martin Aerospace Company gave directions in feet and inches. As a result, the satellite was thrown off course and lost in space. NASA's 125 million USD was squandered on this project.

4. The Lottery

In 2010, a woman from Central England purchased a lottery ticket and waited for the results. Even though she had won a lottery worth 183 million USD, she was not overjoyed when the results were announced. This is the largest lottery prize ever awarded. She was not happy because her husband had thrown the lottery ticket in the trash just one day before the results were announced.

5. Never throw away your bitcoin

In 2009 a man named ‘James Howell‘ owned 7500 bitcoins. But he threw away the hard disk of his computer with his bitcoins. In 2013 bitcoin came in popularity and more and more people started investing in bitcoin. In 2013 the price of his 7500 bitcoins was around 3.5 Million USD and as of 2020 the price of his 7500 bitcoins was around 70 Million USD. This was the biggest mistake made by him and he might cry daily in any corner of his house.

6. The Million Dollar Decimal Error

Back in the time a submarine was being constructed for the Spanish Navy but that submarine never worked for the Spanish Navy. The fixed weight for the submarine was around 7.7 tonnes but one of the engineers made a mathematical mistake or the Decimal Point Error. The engineer removed decimals from the number and printed the weight for around 77 tonnes. After the mistake was recognised the Spanish Government faced a loss of 11 million USD to recover. But even after that the submarine never worked and around 6.3 billion USD was wasted.

7. A Million Dollar Typo by Alitalia

In 2006 Alitalia Airlines faced a huge loss of 7.7 million USD due to its silly mistake. Back in 2006 the cost of Business Class on a flight from Toronto to Cyprus was around 3900 USD but Alitalia Airlines misprinted it for just 39 USD so nearly 2000 people booked their tickets. At first the airline refused to continue the tickets but later they accepted the tickets for 39 USD. As I said above you won’t believe that due to such a silly mistake the company lost around 7.7 million USD. This was the biggest expensive mistake made by any airline ever in human history.

8. London Millennium Bridge

The famous London Millennium Footbridge began construction in 1998 and was officially opened in June 2000. The Thames Bridge was built to allow people to cross the river. The bridge cost £18.2 million to construct. The bridge's engineers concentrated on design, gravity, and sea level. They overlook the force exerted by pedestrians on the bridge. Thousands of people came to see the new bridge on its opening day, but the bridge began to sway. The bridge was eventually closed for that day, as well as for the next two years, in order to make modifications and keep it stable. The reconstruction cost nearly 6.3 million USD, and the company suffered a significant loss.

9. New SNCF Trains

In 2014 France ordered 1800 new trains from the SNCF Company worth 20.5 Billion USD. The trains were ordered to make the railway system better in France. But the Government gave wrong dimensions to the company and trains became little bit wider from the old stations when trains were little slimmer. The Government measured 30 years old railway stations but most of the stations were made 50 years ago and here they made a mistake.


Yahoo was the most visited website or search engine in the world in the 1990s and 2000s. At the same time, was the world's second most visited search engine. received an offer to buy Google for $1 million USD in 1999, but the CEO of declined, which proved to be the biggest mistake of his life. Because Google now has a market value of 280 billion USD and is the most visited website on the planet.
