FD Calculator

A Fixed Deposit (FD) is a safe investment where you deposit a lump sum with a bank for a fixed tenure at a guaranteed interest rate. Interest is compounded quarterly. Senior citizens get 0.5% higher rates. FD interest is fully taxable.

🧮 How This Calculator Works

Inputs:

  • Deposit Amount (P): Principal invested
  • Interest Rate (r): Annual rate
  • Tenure (n): Number of years

Formula (Quarterly Compounding):

A = P × (1 + r/4)4n

Interpretation:

  • Maturity Amount: Total received at the end of tenure.
  • Principal Invested: Your initial deposit (P).
  • Interest Earned: Maturity - Principal = compounded growth.

Quarterly compounding = interest calculated 4 times per year and added to principal.
