Term deposits can be compounded, depending on what you choose to do with the interest.
There are two ways to receive interest from a term deposit: either a lump sum at maturity; or paid on a regular basis, usually monthly. If you get your interest paid regularly, you can get it paid into a transaction account, or back into the term deposit account. By using this second option, you’re getting interest paid on your interest. In other words, it’s compounding.
Having the money paid into a transaction account means you can access it for your day-to-day spending, while compounding the interest means you get a better overall return on your investment. Both have advantages, depending on your needs, but be aware that some term deposit accounts that pay interest regularly may offer a lower interest rate to offset the effect of compounding.
