How it works
Interest on interest
- Start and add: enter a starting amount and how much you add, and how often.
- Rate and time: enter a yearly rate, the number of years, and how often interest compounds.
- Watch it build: the chart and table show your deposits and the interest earned on top.
What this assumes
The rate stays the same the whole time, deposits are made at the end of each period, and interest compounds as often as you choose. Taxes and fees are not included.
