常见问题
What is compound interest?
Compound interest means earning interest on both the original principal and previously earned interest. Over time, this creates accelerating growth.
Does compounding frequency matter?
Yes. More frequent compounding (daily vs annually) results in slightly higher returns because interest starts earning its own interest sooner.
How does this differ from simple interest?
Simple interest is calculated only on the original principal. Compound interest is calculated on principal plus accumulated interest, resulting in faster growth.
Can I see the interest-only portion?
Yes. The principal vs interest breakdown shows how much of the final balance came from your deposits vs how much was generated by compound growth.
