OD Loan vs Personal Loan – Which Is Cheaper?
Unexpected expenses can arise anytime, maybe it’s a sudden medical bill of ₹50,000, urgent home repairs costing ₹2 lakh or a short-term business cash flow gap. In such situations, you may consider borrowing either through a personal loan or an overdraft (OD) facility. But which one is serves the purpose and is cheaper depends on your loan amount, usage pattern and repayment timeline.
Understanding the difference can save you significant money in interest and fees and help you avail the right mode of borrowing.
What Is an Overdraft (OD) Loan?
An OD loan is a flexible credit facility where the bank provides a credit limit instead of a fixed loan amount. You can withdraw money as needed, repay partially or fully at any time and interest is charged only on the amount used, calculated daily.
Features of OD
- Can be secured (against fixed deposits, shares, property) or unsecured. Secured ODs usually have lower interest rates.
- Interest is calculated daily, reducing if you repay early.
- Flexible repayment, no fixed EMIs.
- Ideal for short-term cash needs or recurring withdrawals.
Example
You have an OD limit of ₹2 lakh. You withdraw ₹50,000 for 10 days at 12% annual interest:
- Daily interest = ₹50,000 × (12% ÷ 365) ≈ ₹16.44/day
- Total interest for 10 days ≈ ₹164.4
What Is a Personal Loan?
A personal loan is a fixed loan where you receive the entire amount upfront and repay it in fixed EMIs over a predetermined tenure (usually 12–60 months).
Features of Personal Loan
- It's unsecured, no collateral needed.
- Interest is fixed or floating, applied on the full loan amount from day one.
- Predictable monthly EMIs, suitable for long-term or large expenses.
- Processing fees, GST and prepayment penalties may apply.
Example - A personal loan of ₹2 lakh at 13% p.a. for 12 months:
- EMI ≈ ₹17,700 per month
- Total interest ≈ ₹12,400
Interest Rate Comparison - OD vs Personal Loan
| Feature | OD Loan (Secured) | OD Loan (Unsecured) | Personal Loan |
|---|---|---|---|
| Typical Rates | 9–11% p.a. | 14–18% p.a. | 11–16% p.a. |
| Interest Calculation | Daily, only on used amount | Daily | Monthly, full loan amount |
| Flexibility | Very high | High | Low |
| Best for | Short-term, repeated withdrawals | Short-term, occasional use | Long-term, fixed needs |
Illustrative Scenario
- Need ₹1 lakh for 20 days. OD interest at 12% p.a. = ₹657.
- Personal loan EMI for 1 month (₹1 lakh at 13% p.a.) ≈ ₹8,875.
OD is clearly cheaper for short-term use.
Which Is Actually Cheaper?
1. Short-term, flexible usage
- OD loan wins. Interest is only on what you use, for the days used.
- Example - Temporary cash flow gap, urgent hospital bills or emergency repairs.
2. Long-term, full loan usage
- Personal loan is often cheaper. Paying EMIs spreads the cost predictably and avoids interest on unused funds.
- Example- Home renovation, planned education fees, bulk business investment.
3. Flexibility vs Discipline:
- OD - Flexible but requires careful tracking to avoid overspending; high utilisation may affect credit score.
- Personal Loan - Predictable but less flexible; missing EMIs hurts credit score.
Fees and Charges - OD vs Personal Loan
| Charges | OD Loan | Personal Loan |
|---|---|---|
| Processing fee | Low / Zero | 1–2% of loan |
| Annual review / renewal | Possible 0.25–0.5% | Not applicable |
| Penal interest | 2–3% on overdue | 2–3% on overdue |
| Prepayment / foreclosure | Usually allowed, no charges on secured OD | Charges may apply, 2–5% of principal |
| GST impact | Yes, on fees | Yes, on processing fees |
Note - Secured ODs usually have negligible fees. Personal loans carry multiple fixed costs, which increase the total borrowing cost.
Tenure Differences
- OD loans - Typically 12 months, renewable, interest charged only on usage.
- Personal loans - Fixed tenure, EMIs for 1–5 years, interest applies on full sanctioned amount.
Risks to Consider
- OD loans - Overuse can affect credit score; collateral risk if pledged OD defaults.
- Personal loans - High interest if used short-term; prepayment penalties may apply.
Final Verdict
There is no universally cheaper option.
- Use an overdraft for short-term, flexible cash needs, especially when secured.
- Opt for a personal loan for long-term, planned, full-amount expenses.
The cheapest loan matches your actual need, duration and repayment plan. Always calculate interest and fees before committing.
