Consolidating Debt Moves It, and Sometimes Costs More

Why the payment falls: two levers, pulled at once

A consolidation offer changes two things at the same time, and the sales pitch only shows the result. The four debts above run at a blended 20.6 percent — that is $4,120 of interest a year, $343.33 a month, on $20,000. The offer is 9.9 percent over 84 months, and the payment is $330.99 against the $680 currently going out. Separate the levers and you can see which one did the work. The rate alone, at 9.9 percent but over the 40 months the current budget takes, gives a payment of $589.07 and total interest of $3,563 — that is $3,522 less than the $7,085 the debts cost as they stand. The term alone, keeping 20.6 percent but stretching to 84 months, gives $451.38 a month and $17,916 of interest.

That decomposition is the whole article in two lines. The rate cut is worth real money. The term extension is what makes the payment small, and it is also what puts the interest back. Combined, they give the advertised $330.99 and a total interest bill of $7,803 — more than the $7,085 the unconsolidated debts would have cost. Nobody is lying to you when they say the payment halves; the payment does halve. It is simply answering a different question from the one about cost.

Where the break-even sits

The comparison has a single crossing point, and it is worth finding rather than guessing. Holding the rate at 9.9 percent and sweeping the term, the total interest passes $7,085 — what the debts cost when attacked highest-rate-first on the existing $680 — somewhere between month 76 and month 77. At 76 months the loan costs $7,001 and is still the cheaper option; at 77 months it costs $7,100 and is not. In round terms: at this rate gap, a consolidation under about six years and four months saves money, and one over that spends money to buy a smaller payment.

Two things move that crossover, and both are worth checking against a real offer. A wider rate gap pushes it out — if the debts were all at 26 percent rather than a blended 20.6 percent, the loan would stay ahead over a longer term. A larger budget pulls it in, because paying the debts down faster gives them less time to accrue and lowers the number the loan has to beat. This is why a consolidation quote cannot be judged in isolation: the honest comparison is always against what the same money would have done on the debts you already have.

The fee is borrowed too

Arrangement fees, broker fees and insurance premiums are usually not paid up front. They are added to the amount borrowed, which means you finance them at the loan rate for the whole term. Add a 3 percent arrangement fee to this example and the principal becomes $20,600. The payment goes from $330.99 to $340.92 — $9.93 a month, which is why nobody objects — and over 84 months that difference totals $834. The fee was $600. The other $234 is interest on the fee: a 39 percent surcharge on a charge you were quoted as a flat 3 percent.

With the fee inside, the loan repays $28,637 in total against a $20,000 starting balance, and the interest is $8,037 rather than $7,803. The practical defence is to read the annual percentage rate rather than the headline rate, since the APR is the figure required to fold mandatory costs into the comparison, and to ask explicitly which fees are being added to the principal rather than paid separately. If a broker fee, a guarantee or a payment-protection policy is bundled in, each one is being borrowed at the loan rate for seven years.

The alternative that borrows nothing: avalanche and snowball

Both no-new-loan methods pay the minimum on every debt and put everything left over onto one target. The avalanche targets the highest rate first — here the store card at 30 percent, then 26, then 22, then the personal loan at 12. On the $680 budget it clears all four in 40 months and costs $7,085 in interest, $27,085 in total. The snowball targets the smallest balance first — the $2,000, then $4,000, then $6,000, then $8,000 — and clears them in 41 months for $7,616, a total of $27,616. The avalanche is mathematically better by $531 and one month, which is 7.5 percent more interest for the snowball on a $20,000 balance.

There is a third option that the marketing never presents, and on these numbers it beats everything else: take the consolidation loan and keep paying the old $680. The 9.9 percent principal of $20,600, fee included, clears in 36 months with $3,202 of interest — $23,802 repaid in total, which is $3,283 less than the avalanche and four months sooner. The loan is not the problem. What turns a cheaper rate into a more expensive outcome is spending the payment reduction rather than the rate reduction.

The variable that decides most real outcomes

Consolidation does not delete a credit line; it empties one. The cards that were paid off still exist, with their limits restored, and the arithmetic of what happens next is easy to write down. Suppose $8,000 goes back onto a card at 22 percent and you service it with the $339.08 the consolidation freed up. It takes 32 months and $2,575 of interest to clear — while the seven-year loan is still running. Total debt at that point is $28,600 against the $20,000 you started with, and the monthly outgoing is back to where it was, only now with three more years of loan behind it.

This is not a moral failing and it is not rare. It is what happens when the underlying cash-flow gap that created the balances has not changed, and consolidation on its own does not change it. The measurable things worth checking before signing are narrow and concrete: whether the emptied accounts can be closed or limited, whether the loan is secured on your home — which converts an unsecured debt into one that can cost you the house, a change in kind rather than in price — whether there is an early-repayment charge if your circumstances improve, and what the APR is with every mandatory cost inside it. Free regulated debt advice exists in most countries and costs nothing to ask.

Frequently asked questions

How can a lower interest rate cost me more money?

Because interest is charged on a balance for a length of time, and consolidation usually cuts the rate while multiplying the time. In the worked example the rate falls from a blended 20.6 percent to 9.9 percent, but the repayment period stretches from 40 months to 84. The rate cut alone would have saved $3,522; the term extension costs more than that back, and the total lands at $7,803 instead of $7,085. The payment is smaller every month, and there are far more of them.

Is a smaller monthly payment ever the right goal?

It can be. If the current payments cannot be met, arrears, default charges and enforcement cost far more than the extra interest on a longer term, and a payment you can actually make has a value the arithmetic above does not capture. The point is to know the price: on these numbers, buying a $349 reduction in the monthly outgoing costs $718 of extra interest over seven years. That is a defensible trade for someone whose budget does not balance, and a poor one for someone whose budget does.

What rate does a consolidation loan need before it clearly wins?

There is no universal threshold, because the answer depends on the term as much as the rate. The test that does generalise: work out what your existing debts would cost if you cleared them at the payment you are making now, then find the longest term at which the new loan's total interest stays below that number. In the example, 9.9 percent beats $7,085 up to 76 months and loses from 77 onward. Change the budget or the balances and that crossover moves, which is exactly why it is worth calculating on your own figures rather than adopting anyone else's rule of thumb.

Should I let the loan be secured against my home to get a better rate?

That is not a question a calculator can answer, and this article will not answer it for you. What can be stated plainly is what changes: an unsecured debt is a claim on you, while a secured one is a claim on the property, so a default that would previously have meant collection activity can mean losing the home. The rate is usually lower for exactly that reason — the lender's risk fell because yours rose. Anyone considering it should take regulated advice first, and free debt advice services exist in most countries.

Are the rates in this article real market rates?

No, and they are not presented as such. The 30, 26, 22, 12 and 9.9 percent figures are illustrative inputs chosen to make the mechanism visible, and the arithmetic built on them is exact for those inputs and nothing else. Real card, store-card and personal-loan rates differ by country, by lender, by credit profile and by month. Put your own balances, rates and payment into a calculator, and compare the total interest — not the monthly payment — before deciding anything.
