What Is a Fixed Deposit?

A fixed deposit (FD), also called a term deposit or certificate of deposit (CD), is a savings instrument where you deposit a lump sum with a bank for a fixed period at a guaranteed interest rate. It offers higher returns than a regular savings account with very low risk.

Fixed Deposit Formula

Simple Interest FD

Maturity Amount = Principal + (Principal × Rate × Time ÷ 100)

Compound Interest FD

Maturity Amount = P × (1 + r/n)^(n×t)

Most banks compound quarterly (n=4) or monthly (n=12).

Example Calculation

$10,000 deposited for 2 years at 5.5% per annum, compounded quarterly:

  • r = 5.5% ÷ 4 = 1.375% per quarter
  • n×t = 4 × 2 = 8 quarters
  • Maturity = $10,000 × (1.01375)^8 = $11,148
  • Interest earned: $1,148

Tips for Fixed Deposits

  • Laddering: Split your investment across multiple FDs with different maturity dates for liquidity.
  • Auto-renewal: Set FDs to auto-renew to avoid missing better rates.
  • Tax: Interest earned is usually taxable as ordinary income.
  • Penalty: Early withdrawal typically incurs a penalty of 0.5–1% reduction in rate.

Frequently Asked Questions

A fixed deposit locks your money with a bank for a set period at a fixed rate. It is low-risk and FDIC-insured (in the US). The trade-off is limited liquidity.
APR (Annual Percentage Rate) is the nominal rate. APY (Annual Percentage Yield) is the effective rate after compounding. More frequent compounding means higher APY than APR.
Most term deposits allow early withdrawal with a penalty (often 1-3 months of interest). Check your bank's terms before locking in.
