The interest on $10 million varies greatly by interest rate, from a modest amount (e.g., $40,000-$50,000 annually at low savings rates) to several hundred thousand dollars (e.g., $400,000-$450,000 at higher CD rates, or potentially more with diversified investments like bonds or dividend stocks). For example, at a 1% rate, it's $100,000/year; at 4%, it's $400,000/year; but the specific rate depends on the investment vehicle (savings, CD, bonds, stocks) and current market conditions.
Savings accounts
With a traditional savings account, you might find an interest rate near the June 2025 average of 0.38%, but with a high-yield savings account, that interest rate might top 4%. On a $10 million portfolio, you could receive an annual income of $400,000 per year.
Generally, a liquid net worth of at least $1 million would make you a high net worth (HNW) individual. To reach a very high net worth status, you'd need a net worth of $5 million to $10 million. Individuals with a net worth of $30 million or more might qualify as ultra-high net worth.
What is the monthly interest on 100 million dollars? The quick answer—You could earn $416,667 per month in pre-tax interest income with a Certificate of Deposit (CD) at 5% interest. By investing in the stock market and yielding 10%, you could earn $833,333 per month. With 1% interest: $83,333 per month.
How long does $1 million last after 60? If you withdraw 4% annually, it may last 25–30 years. Living off interest only, you might get $40,000–$50,000 per year indefinitely, depending on rates. A lifetime income annuity can pay $40,000–$80,000 per year for life, regardless of how long you live.
If you wanted to earn an average $3,000 per month, you would need to invest $1.6 million ($36,000 divided by 2.2%). While there is nothing wrong with passive investing, most investors are likely to do much better if they build their own investment portfolio.
"You can live off $500,000 in the bank and do nothing else to make money, because you can make off that about 5% in fixed income with very little risk. Or you can make 8.5 to 9% in equities too, if you're willing to ride the volatility."
Traditional savings accounts, generally reserved for short-term savings, available at banks generally yield low rates of interest. A million-dollar deposit with the average 0.45% APY would generate $4,510.08 of interest after one year. If left to compound daily for 10 years, it would generate $46,027.51.
The safest place to put $1 million dollars would be in a combination of insured bank accounts and conservative investments, such as bonds and CDs, to ensure a balance of liquidity and stability.
Costs and Lifestyle
As we noted up top, with $10 million in retirement savings, you very likely can generate more than enough income to live a very comfortable life. Even without investment growth, $10 million allows you to withdraw $100,000 per year for 100 years.

The magic number: Living off interest
