Fixed Deposit (FD) Calculator

What is a Fixed Deposit (FD)?

A Fixed Deposit (FD) — also called a Term Deposit — is one of the safest and most widely used investment instruments in Pakistan and across South Asia. You deposit a lump sum with a bank or financial institution for a fixed period (typically 3 months to 5 years) at a pre-agreed interest rate. Unlike a savings account where rates fluctuate, an FD locks in your rate for the entire tenure, guaranteeing your return regardless of market conditions. The bank compounds the interest at a chosen frequency — monthly, quarterly, semi-annually, or annually — and at maturity you receive your original deposit plus all accumulated interest. FDs are backed by the Deposit Protection Corporation for amounts up to PKR 500,000, making them extremely low-risk for capital preservation. The key metric when comparing FDs across banks is not the advertised nominal interest rate but the Effective Annual Rate (EAR) — the true annualised return after accounting for how often interest compounds. Two FDs with an identical 12% nominal rate will produce different final amounts if one compounds monthly and the other compounds annually. Monthly compounding at 12% produces an EAR of 12.68%, meaningfully more than annual compounding at the same nominal rate. The FD calculator shows you both the nominal rate and the EAR, enabling genuinely apple-to-apple comparisons.

How to Use This Calculator

Enter your deposit amount — the lump sum you plan to invest. Enter the annual interest rate offered by your bank (Pakistani banks currently offer FD rates between 10% and 22% depending on the tenure and institution — always verify the current rate directly with your bank). Enter the tenure in years. Select the compounding frequency from the dropdown: monthly, quarterly, semi-annual, or annual. Click Calculate to see your maturity amount, total interest earned, effective annual rate, and return on investment percentage. Try different compounding frequencies at the same nominal rate to see exactly how much extra return monthly compounding produces versus annual.

💡 Pro Tips

• ✓Always compare Effective Annual Rate (EAR), not the nominal rate — monthly compounding at 12% gives 12.68% EAR, a meaningfully different return over long tenures.
• ✓Longer FD tenures usually offer higher interest rates — use a laddering strategy (splitting deposits across 6-month, 1-year, and 2-year FDs) to balance higher returns with liquidity access.
• ✓Premature withdrawal penalties reduce your effective return — confirm your bank's early-withdrawal policy before locking in.
• ✓Senior citizens often receive 0.5–1% additional interest on FDs — check if you or a family member qualifies.
• ✓National Savings certificates often offer higher rates than bank FDs with government backing — compare before committing.
