Frequently Asked Questions
Q What is the Compound Interest formula with monthly contributions?
A = P(1 + r/n)^(nt) + PMT × [((1 + r/n)^(nt) - 1) / (r/n)], where P = Initial Principal, PMT = Monthly Deposit, r = Annual Interest Rate, n = Compounding periods per year, and t = Years.
Q What is the 'Rule of 72' in compound interest?
The Rule of 72 is a mental shortcut to estimate how many years it takes for an investment to double: Years to Double ≈ 72 / Annual Interest Rate. For example, at an 8% return, money doubles in 72 / 8 = 9 years.
Q How does compounding frequency impact total returns?
More frequent compounding (such as daily or monthly vs annually) results in slightly higher effective annual yields (APY) because interest is reinvested sooner to generate interest of its own.
