Debt consolidation, and the problem it cannot solve

What consolidation actually is

One new loan repays several existing debts, so you owe one lender instead of five and make one payment instead of five. Nothing is forgiven. The total you owe on the day it completes is the same total you owed the day before.

In India the product is almost always an unsecured personal loan taken for the purpose — sometimes a gold loan or a loan against property, which is a materially different bargain and gets its own section below. The brochure word is “consolidation”; the underwriting, the fees and the paperwork are a personal loan's.

Only three things change. The rate you pay, the tenure over which you pay it, and the number of payments each month. The first two change what the debt costs. The third changes only how it feels — and it is what the sales conversation is built around.

That is not nothing — five due dates is five chances to miss one. But a single due date is an administrative improvement, not a financial one, and the two are worth separating before you look at any offer.

The rate you are actually paying now

On rate, consolidation is worth doing only if the new rate is below what you pay today across everything being folded in. Working that out has one trap.

Weight the rates by balance, not by the number of debts. Suppose you carry ₹1 lakh on cards quoted at 36% a year and ₹4 lakh remaining on a car loan at 11%. The average of 36 and 11 is 23.5%. The rate you actually pay is (₹1 lakh × 36% + ₹4 lakh × 11%) ÷ ₹5 lakh, which is 16%.

Now an offer arrives at 18% to clear both. Against the simple average it reads as a saving of 5.5 percentage points. Against what you actually pay it is 2 percentage points worse — on ₹5 lakh, for years.

The arithmetic there favours folding in the ₹1 lakh of card debt and leaving the car loan alone. A consolidation does not have to swallow everything. Fold in only the debts whose own rate is above the new loan's; every cheaper debt makes the deal worse by being included. And the cheapest debts are usually the largest, because the cheap rate and the size come from the same place — a home or car loan is secured on the thing it bought, which is why the lender charges less and why the amount is big. That is what makes including them tempting.

One thing the headline rates hide, and for once it runs in consolidation's favour. A card rate is set per month and annualised by multiplying by twelve: 3% a month is presented as 36% a year. On a loan you are servicing, 36% would cost 36% — the interest is paid off each month and never gets the chance to earn anything itself. On a revolving card balance it is not paid off. It joins the balance and starts earning, so ₹1 lakh left untouched for a year becomes 1.03 multiplied by itself twelve times: about ₹1.43 lakh, an effective 42.6%. The distance between a carried card balance and a 14% loan is wider than the two headline numbers make it look, and it widens the longer the balance sits.

The tenure trap, priced

This is the part that turns a lower rate into a higher cost. Every input is stated so you can redo it.

Take ₹4 lakh of card balances compounding at 3% a month — the 36% a year the statement quotes, an effective 42.6% on anything left unpaid — and a consolidation offer at 14% a year, with about ₹19,200 a month available either way.

The three loan rows come off the standard reducing-balance instalment formula at 14% a year on ₹4 lakh; the card row is ₹4 lakh growing 3% a month against a ₹19,200 payment until it clears, which it does part-way through the thirty-fourth month.

Read the second row against the first: at the same monthly outgo, the rate saving is worth about ₹1.76 lakh and ten months. That is consolidation working exactly as advertised.

Now read the second row against the fourth. Same borrower, same lender, same 14%. The fixed monthly instalment — the EMI — more than halves, which is what makes the 60-month offer feel generous, and the interest bill goes from about ₹60,900 to about ₹1.58 lakh. Nothing about the rate changed. The tenure did all of it.

The rule that survives every version of this: take the rate saving as time, not as a smaller EMI. Ask what the EMI would be over the months you would have needed anyway, and start there. A longer tenure is a choice for cash flow that genuinely cannot support the shorter one, not a default because it was quoted first. It is the same tenure reset that undoes a balance transfer.

The restored limit — why this one transaction is different

There are three ordinary ways a ₹1 lakh card balance goes away, and they are not variations of the same thing. Set them side by side.

• You pay it from savings. What you owe falls by ₹1 lakh, available credit rises by ₹1 lakh, savings fall by ₹1 lakh. No new monthly obligation.
• You pay it down from income over months. Both move gradually, and the cost is paid in months of constrained spending. No new monthly obligation.
• You consolidate. What you owe does not fall at all — it moves. Available credit rises by ₹1 lakh immediately. And a compulsory EMI appears, making every future month tighter.

Consolidation is the only one of the three that increases your borrowing capacity without reducing what you owe. It is also the only one that makes your monthly slack smaller on the same day. Both halves of your flexibility move against you at once: less room in the month, more credit available to fill the gap with.

That combination is not a character flaw waiting to happen. It is the precise condition under which cards get used — a tighter month and an empty limit in the same wallet. The other two routes cost cash or time up front and deliver the relief afterwards. Consolidation reverses the order: the capacity arrives today, the price is paid entirely in the future.

Call it the restored limit. Once you have seen it the question stops being “is the rate lower” and becomes “what happens to ₹4 lakh of freshly empty credit lines on Monday morning.”

The failure mode: the loan and the balances

The failure is not exotic. It follows directly from the two things the previous section put in the same wallet, and it looks like this.

₹4 lakh of card debt becomes a 60-month loan at ₹9,307 a month. The relief is immediate and genuine — outgo drops sharply, the cards read zero, the position looks repaired. Eighteen months later the cards carry ₹2 lakh again, because the monthly deficit that built the first ₹4 lakh never went anywhere.

You now owe ₹6 lakh where you owed ₹4 lakh. Your fixed floor is the EMI plus the card minimums, the high-rate debt is back at its original rate, and the loan has another 42 months to run — you cannot unwind it by stopping. The consolidation did not fail. It worked perfectly on the arithmetic, while the thing generating the debt was left running.

If it is the second, the work is on the monthly gap first and the repayment ordering — snowball or avalanche — second. A consolidation taken before either is a lower interest rate applied to a problem that is not an interest rate problem.

When it genuinely helps

Five conditions. It is worth being strict about all of them, because the offer is designed to satisfy one of them loudly.

1. The blended rate falls. Weighted by balance, as above, and computed including fees rather than on the headline rate.
2. The tenure does not stretch. Months to zero under the new loan is no greater than under the plan you would otherwise have followed. If no such plan exists, write one down first — otherwise you are measuring a real loan against an imaginary alternative.
3. The fees clear. Processing fee, the tax on it, foreclosure charges on debts closed early, bundled insurance. Total saving must exceed all of it with room to spare.
4. The limits are dealt with the same day. Not later, not “carefully”. Reduce them, or take the cards out of your wallet and out of every saved-card field, before the loan disburses.
5. The cause is addressed, or was a one-off. See above.

Where all five hold, the arithmetic is not close — the second row of the table is a ten-month, ₹1.76 lakh improvement for the same money out of the door each month. No cleverness, no catch. Which is what makes the cases where it fails frustrating: the tool is fine.

What changes if the new loan is secured

A gold loan or a loan against property usually offers a much lower rate than an unsecured personal loan. The reason is not generosity: the lender has something to take.

Consolidating card debt into a secured loan converts an obligation that is, at worst, a bureau and collections problem into one where a specific asset stands behind it. The rate falls because the risk moved — to you, in a different form. That is the trade, and it can still be the right one.

What makes it the wrong one is taking it without pricing the tail. Unsecured debt in distress is usually worked out on paper — rescheduled, negotiated down, in the last resort written off — and the cost lands on your credit record rather than on anything you own. None of that is a right you can insist on, and it is slow and unpleasant, but it exists. A gold loan in distress is jewellery being auctioned; a loan against property in distress is the house. The probability may be small; the consequence is not, and a lower rate does not compensate for it automatically.

The narrow case where it clearly works: a large, high-rate balance, a secured rate far below it, a short tenure, and income that services the EMI comfortably even in a bad quarter.

What to ask before signing

Six questions, most of them with a one-line answer, none of which a lender can reasonably refuse.

1. Total repayable in rupees, over the tenure offered. Not the EMI, not the rate — the total. Then the same figure at a shorter tenure.
2. Every fee, itemised, including the tax on fees and anything deducted from the disbursal rather than charged separately.
3. Is the rate fixed or floating, and if floating, what is the benchmark and what is the spread stated separately?
4. What does prepayment cost, and after how many instalments is it allowed? A loan you can overpay freely is a different product from one you cannot.
5. Is any insurance bundled, is it optional, and is the premium financed by the loan — which means paying interest on it for the full tenure.
6. Is a top-up offered alongside? Additional borrowing packaged with a saving is a separate decision wearing the saving's clothes.

One more, on the cards. There is a real tension worth naming. Part of a credit score is how much of your available card limit you are using — balance divided by limit, the credit utilisation ratio. Closing cards after consolidating shrinks the denominator, so the ratio can rise on whatever remains even though you owe less. The behavioural fix and the score mechanic point in opposite directions.

Separate limit from access and both are satisfied: reduce a limit rather than close the account, or keep it open while removing the card from your wallet and from every stored-card field online. The score is a means, not the goal — one kept intact by preserving the exact conditions that produced the debt is not a win.

Running the comparison yourself

All of this is arithmetic you can finish in one sitting. List each debt with its balance and rate, weight the rates by balance, and write down the months to zero under the plan you would follow without consolidating. Then ask the lender for the total repayable, in rupees, at two tenures. One subtraction settles it, and it is immune to how attractively either side is presented. The EMI mechanics behind those totals are worth understanding first.

The harder comparison comes next: once the debt is cleared, whether spare money goes to prepaying what remains or to investing it. That is certain saving against uncertain return, and the honest way to weigh it is against the full historical record rather than an assumed rate. FNOTrader's Mutual Funds app runs on the full published history of daily scheme prices — around 34 million net asset value, or NAV, rows from AMFI, the industry body that collects them — and reports rolling-return distributions including the worst window on record, which is the side of that comparison most calculators leave out. Past performance is not indicative of future returns.
