Who wants to be a multi-millionaire…? Plenty of people, is likely to be the answer! $100 million in your pocket qualifies you as a multi multi-millionaire in anyone’s book though! So, what is the yearly interest on $100 million dollars if you put that money in the bank?

**The quick answer is that you could make as high $4.65 million a year of pre-tax interest income on $100,000,000 if you invest it in a 1-year Certificate of Deposit (CD). On a monthly basis, this means that the pre-tax interest income on $100 million would be $387,500. This works out to $89,423 of interest per week, or $12,740 of interest per day. **

Interestingly enough, because the yield curve is currently inverted, you can get a high interest rate even on shorter-term CDs. Normally, you would only get these rates if you were in a longer term, say 5-year, CD!

If you wanted to access that money on an on-demand basis, your best bet would be to be deposit it in a savings account which lets you have access to that money any at very short notice. The obvious downside to such accounts is that the interest rate on offer is lower – in the 3% to 4% range. That’s not bad, but still much lower than what you would get in a CD.

## Can I live for the rest of my life on the interest of $100 million?

I honestly believe that you should have no issues living off the interest on your $100 million in the bank for a very long time. As I mentioned above, at the minimum, you will generate $4.65M a year in pre-tax interest, which works out to $387.5k a month, $89.4k a week, or nearly $12.7k each day! In fact, even with $50 million dollars in the bank, you would not face any issues. While of course these are pre-tax figures, it would still be difficult to run out of this much money!

You have achieved the much desired status that we all want: financially free! Congratulations! Now here is where things get really interesting – if you stick to only using the interest generated by that pot of money, in theory, that original pot of money never goes away. Not only you, but entire generations that come after you could easily live off that money without degrading the pot!

Of course inflation would eat away at the purchasing power of the 100 million US dollars over time, so the best option would be to take some of that money and invest in areas that generate higher rates of return. There are a variety of opportunities – like real estate, the stock market, or even buying businesses outright – which could help you maintain the value of that money over many years to come!

With a $100 million in the bank, you’re in a league of your own. If you play your cards right and get the right financial advice, you could even be on your way to becoming a billionaire soon!
