よくある質問
What is compound interest?
Compound interest means you earn interest on your interest. Formula: A = P(1 + r/n)^(nt), where n is the number of compounding periods per year.
Which compounding frequency is best?
More frequent compounding means slightly higher returns. Daily compounding gives the most interest, but the difference from monthly is small.
