FAQ
- What does the compounding setting change?
- Yearly, quarterly, monthly, or daily changes how often interest is added. More frequent compounding grows the balance a little faster at the same annual rate.
- Is the deposit added every compounding period?
- Yes. A monthly setting means the deposit is made each month. Switch to yearly if you only add money once a year.
- Does this include tax on interest?
- No. The result is the mathematical balance before any tax on earnings.
