What is FD Calculator?
An FD (Fixed Deposit) calculator is a financial tool that computes the maturity amount and total interest earned on a fixed deposit investment using the formula A = P × (1 + r/(4×100))^(4×t), where interest is compounded quarterly as per standard Indian banking practice. It takes the principal amount, annual interest rate, and tenure to calculate the exact maturity value. For example, a ₹1 lakh FD at 7% for 3 years compounds quarterly to approximately ₹1,23,141, earning ₹23,141 in interest. Senior citizens typically get 0.25-0.75% higher rates. The calculator also shows TDS implications (10% TDS on interest over ₹40,000/year) and compares cumulative (interest reinvested) vs non-cumulative (periodic payout) FD options. Major banks like SBI (6.5-7.25%), HDFC (3.5-7.75%), and Post Office (7.5%) offer varying rates that can be compared using our tool.
