Need cash for 10 days? Don't break your FD (and lose 1% penalty). Take an OD against it. We decode the math of 'Loan Against FD' vs 'Premature Withdrawal'.

It is the 25th of the month. You have a medical emergency, or check-bounce risk, or a sudden travel plan. You need ₹50,000. You have a Fixed Deposit (FD) of ₹5 Lakhs in the bank.
What do you do? 95% of people log in to Netbanking and click "Premature Closure". Breaking the FD. 5% of people (the wealthy ones) click "Overdraft against FD".
The first group loses money. The second group effectively pays zero real cost.
In this guide, we will mathematically prove why Breaking an FD is a financial sin, and how the Overdraft (OD) facility is the greatest liquidity tool Indian banks offer.
When you break an FD, you think you are just taking your own money back. But the bank punishes you in two ways.
Most banks charge a 1% Penalty on premature withdrawal.
Compound Interest works best in the later years.
What is it? An Overdraft (OD) or "Loan Against Deposit" (LAD) is a facility where the bank gives you a credit limit (usually 90% of your FD value).
** The Rate:** Usually FD Rate + 1%.
Wait. 8% is higher than 6% (Penalty Rate). How is this cheaper? Because you pay 8% on ₹50,000 (Borrowed), while you earn 7% on ₹5,00,000 (Corpus).
Let's take a real-life scenario.
You break the ₹5L FD.
You take ₹1L from OD.
1,00,000 * 8% * (30/365) = ₹657The Verdict: Paying ₹657 is infinitely cheaper than losing the compounding on ₹5 Lakhs and paying a penalty.
There is a mathematical Breakeven Point.
Use OD If:
Break FD If:
Wealthy businessmen use this to manage Working Capital.
Why? Because Business Loans cost 12-15%. FD Overdraft costs 8%. It is the cheapest form of credit available in India. Cheaper than Gold Loans, cheaper than Personal Loans, cheaper than Credit Cards.
Taking an OD against FD is a Secured Loan.
You don't need to visit the branch.
Do not treat this as "Free Money".
Liquidity is King. But you don't need to kill your investments to get liquidity. Next time you have a short-term crisis, don't press the "Panic Button" (Break FD). Press the "Smart Button" (Overdraft). It costs less than a pizza to save your wealth compounding.
