How much interest do you earn on one million dollars?

This was the question that Clint at Accumulating Money asked in a ‘classic’ post – I commented on it earlier this year and still receive click-through’s two or three months later. It must be a very popular question!

I’m not sure why, because it implies that people are happy to just have their life savings ‘sit’ in CD’s …

… but, here’s the answer to the “million dollar” question courtesty of Accumulating Money anyway:

So, to answer the question, how much interest do you earn on One Million Dollars (assuming a 4% interest rate, compounded monthly)?

One Day – $109.59

One Month – $3,333.33

One Year – $40,741.54

Five Years – $220,996.59

Ten Years – $490,832.68

Twenty Years – $1,222,582.09

I think this related question asked by Afroblanco at Ask Metafilter – repeated on Get Rich Slowly (which is where I picked it up) – really goes to show how The Savers (as opposed to The Investors) think:

What’s the safest possible thing that I can do with my money?” :

I take bearishness to an extreme. Having witnessed the 2000 tech crash, I have no faith in the stock market or the US economy. I keep all of my money (USD) in a savings account. However, with the recent financial turmoil, I have a few questions:

  1. Is it conceivable for the FDIC to fail?
  2. If so, is there a place where I can put my money that will be safer than a savings account?
  3. What’s the safest, most risk-free way for me to save money and not get killed by inflation and the tanking US dollar?
  4. If there is a safe way for me to save money and not be punished by inflation and the depreciating dollar, is there a way that I can do this without having to stress out and micromanage my finances? I don’t want to be checking the finance page and making adjustments every day.

Even though I follow finance news, I’ve never done any investing or money management other than socking money away in my savings account. I’m a n00b, I admit it.

OK … I confess …. I am like our friend, Afroblanco … very risk-averse; yet I have become rich by understanding that it is actually safer to invest than not.

The GREATEST RISK that our friend can take is NOT TO INVEST … inflation will just eat up any bank deposit/CD strategy.

Take Accumulating Money’s example above:

One million dollars approximately doubles in 20 years … but, inflation will halve its buying power!

Think about it, if the average bank interest rate is 4% (pushing the value of your savings UP) and inflation averages 4% (pushing the buying power or value of your savings DOWN), what have you gained in 20 years?

Nothing …

Now, if you just push your savings into a low cost Index Fund that averages, say, an 8% return over the 20 years, then the same 4% inflation means that you should effectively DOUBLE the value (or ‘buying power’) of your million dollars over 20 years.

But, Afroblanco is even better off BUYING The Bank [i.e. investing in the Bank’s stock] than putting his money in The Bank. The risk of failure is about the same (if the bank fails you will lose the money that you have IN the bank’s vault as well as the money IN the bank’s stock), yet, as long as he has a long-term view (minimum 20 to 30 years), the former strategy will make him rich and the latter broke.

If the bank stock averages just 12% average growth over 20 years – as any well-picked Value Stock, can easily do – then Afroblanco won’t just double the buying power of his money ONCE, he will get to double it TWICE … that’s $4 million AFTER the effect of inflation (or, the $1 million grows to $10 million in ‘raw’ dollars).

What about risk? Aren’t bank deposits FDIC Insured?

[AJC: Well, yeah … up to a paltry $100kof course, you could open up 4 bank accounts at 4 different banks  … but, $400k is hardly what I hope my readers are aiming at!]

But, inflation is a much bigger risk: 100% certain to eat up your money … and, would the Federal Government (the same entity backing the FDIC) allow a Major US Retail Bank to fail?

I guess we’ll find out in the next few months!

If you don’t believe that’s likely, then isn’t your money just as safe in The Bank as it is in the bank?

[AJC: think about it 😉 ]

And, doesn’t The Bank’s stock at least meet the overall market returns which averaged 8% p.a. for the past 100 years … what have bank deposits averaged in that time? 3%? 5%?

The point here is not necessarily to buy stock in The Bank … rather it’s to think about Investing rather than Saving …

Before suggesting WHAT to invest in, we need to know HOW long is our friend is expecting his money to last? Assuming that our friend is a hands-off investor, here’s what I suggest as the lowest-risk strategies possible:

If less than 30 years, then TIPS are a an option – PROVIDED that he can live off the inflation-adjusted interest (unfortunately, very unlikely in the current low interest environment – but, in 5/10 years, who knows?).

If 30 years or more, then a low-cost Index Fund is ideal for a hands-off investor. There has been NO 30 year period since the recording of the stock market indices where the market has not produced a positive return well above inflation.

If he is more hands on and/or more knowledgeable, then I would recommend no more than 4 or 5 well-selected individual stocks and direct investment in real-estate, for any time period 10 years or greater.

Inflation forces us to invest … because of this, inflation is our friend!
