FAQ
Compound interest ka formula kya hai?
A = P × (1 + r/n)^(n×t), jahan P = principal, r = annual rate (decimal), n = compounding frequency per year, t = years. Compound interest = A − P.
Simple aur compound interest me kya difference hai?
Simple interest sirf principal pe lagta hai. Compound interest me har period ka interest principal me judta hai aur agle period me us par bhi interest milta hai — isliye long-term me compound interest bahut zyada hota hai.
Compounding frequency se kitna difference padta hai?
Jitni zyada frequency, utna zyada return. ₹1 lakh @ 8% × 10 saal: yearly = ₹2.16L, quarterly = ₹2.21L, monthly = ₹2.22L. Difference chhota lagta hai lekin bade amounts pe significant hai.
Rule of 72 kya hai?
Paisa double hone ka approximate time = 72 ÷ interest rate. E.g. 8% pe paisa ~9 saal me double hota hai.
