Frequently asked questions
What is compound interest?
It's interest earned on both your original amount and the interest already added — so your money grows faster over time.
How often should interest compound?
More frequent compounding (e.g. monthly vs annually) yields slightly more. Many savings accounts compound monthly or daily.
