This depends on the product that is offering interest. For example, putting $100k in a US savings account will likely yield 0.10% per year. This means that annually, a $100k investment would generate just $100 in interest. A better option in this respect would be to consider bonds that have been issued by the US government. As of writing, yields of over 3% are available. Corporate bonds can yield an even higher interest rate, albeit, this is reflected in the risk associated with the issuer.
