Frequently Asked Questions
What is compound interest?
Compound interest means you earn interest on both the original principal and on interest already added. Over time that accelerates growth compared with simple interest.
Does compounding frequency change the result?
Yes. More frequent compounding (for example monthly vs annual) usually produces a slightly higher final amount at the same nominal rate.
Is this financial advice?
No. The calculator is an estimate helper. Real returns, fees, and taxes can differ — verify with a qualified advisor when needed.
