What is the compound interest formula?

A = P × (1 + r/n)^(n×t), where P is principal, r is annual rate, n is compounding frequency per year and t is years.

Which compounding frequency gives the best return?

Daily compounding beats monthly, which beats yearly — but the difference is small at typical rates. Time horizon matters far more than frequency.

Is CAGR the same as compound interest?

CAGR is the compound annual growth rate — the constant rate that would grow your principal to the final value. It is derived from the same formula.

How is this different from SIP?

Compound interest assumes a single lumpsum. SIP adds monthly contributions on top of compounding — use the SIP calculator for that scenario.
