FAQ

Can compound interest be bad?

Compound interest is bad if it is working against you. For example, if you have a credit card and you fail to pay off the full amount every month. In this case, your interest would be accruing interest. Credit card debt can be particularly bad as the APR (Annual Percentage Rate) for many credit cards is around 20%. Consider that a good rate for a savings account these days is in the region of 0.5% and you will understand just how bad compounding can be in relation to the debt that can be accrued on credit cards.

How can compounding make my savings grow?

If you want to see your savings grow then compound interest can be your best friend. Compounding means earning interest on top of interest. This also means that the longer you leave your money in your account, the more you can benefit from the effects of compounding.

  1. Awesome calcultor! – People need to understnad the value of compounding! People with kids should start their kids off in a 7% growth product and then have them take it over after educating them when they are 18. They will have a millon pound fund by the time they retire at 65, and if you start that when they are very young, say 5 years old that will only be a small amount each month….
