Frequently asked questions
What is compound interest?
Interest earned on both your deposits and the interest already added. Over time it grows faster than simple interest.
Does compounding frequency matter much?
A little. Daily compounding earns slightly more than yearly at the same rate. The rate and the time you leave the money matter far more.
Are taxes and inflation included?
No. Results are before taxes and inflation, so real growth will be lower.
