FD Calculator Formula - How Banks Calculate Interest?

Banks in India use quarterly compounding formula: Maturity = P * (1 + r/4)^(4*n) where P is principal, r is annual rate/100, n is years. For example, Rs 5 Lakh at 7.5% for 5 years: Maturity = 500000*(1+0.075/4)^(20) = Rs 7,24,974 approx. Our calculator uses same formula with daily update. If you choose 7.5% for 5 years, you get Rs 2,17,506 interest which is 43% extra on principal. This is power of compounding quarterly, not yearly.

Many users search for FD calculator monthly interest payout vs cumulative. Monthly payout FD gives you interest every month in your savings account, but maturity is less. Cumulative FD gives you full maturity at end, higher returns. Our calculator shows cumulative by default, which is best for wealth creation. If you want monthly income, divide total interest by months shown in monthly interest box.

RD Calculator Formula - Monthly Compounding Magic

RD formula is slightly different: Maturity = M * [((1 + r/4)^(4*n) -1) / (1 - (1 + r/4)^(-1/3)) ] where M is monthly installment. Simplified for users, if you invest Rs 10,000 monthly for 5 years at 7.5%, total investment is Rs 6,00,000, interest is Rs 1,20,500, maturity Rs 7,20,500.
