You CAN get rich on any income and THAT’S the power of compound interest investing.
Compound interest is just your money times an interest rate and how long you let it grow.
You get compound interest in any investment or account that pays a return and you leave the money in your account to grow.
You can invest in individual bonds or go with my favorite, get thousands of individual bonds with one fund like this iShares High Yield Corporate Bond ETF, ticker HYG.
The Schwab US Dividend ETF, ticker SCHD, pays a 2.9% yield and charges one of the lowest expense ratios you’ll see at just 0.06% a year.
