What's the equivalent of $1,000,000,000 in 2009 in today's money?

As inflation rises, the value of money decreases, that's why in 2009 you could buy a lot more with $1,000,000,000 than you can today.

You should always keep this in mind whenever you come across a price or dollar value from the past, as the economy is constantly evolving, and comparing how much something used to cost in the past with how much it costs today, without adjusting for inflation, can lead to confusion and missinformation.

This also has a huge impact on your savings. If you had put those $1,000,000,000 into a savings account that paid no interest in 2009, and decided to use that money in 2023, you would find that the purchasing power of that money had decreased by 30.1% to $699,041,542.
