Refinancing and restructuring: when replacing a debt pays off
Refinancing means replacing a debt with a new one. It can lower the interest rate, change the monthly payment or push the repayment date further away, but it usually costs money up front. This lesson builds the break-even test for a refinance with a fictional $200,000 loan, shows how a longer term can hide a higher total cost, looks at two companies that refinanced in 2025, and explains how restructuring differs when a borrower can no longer pay.

Replacing one debt with another
Refinancing means taking a new loan to pay off an existing one. A borrower does it to get a lower interest rate, to change the monthly payment, to change the length of the debt, or to switch from one type of loan to another. It looks like a free improvement, but it rarely is: the new loan usually carries fees and other costs, and the repayment clock may start again. The question is whether the benefit is worth more than the cost, and for how long.
The earlier lesson on the cost of borrowing showed how a fee spreads over the life of a loan. This lesson turns that into a decision tool for a fictional $200,000 loan. It then looks at two companies that refinanced in 2025 and explains how restructuring works when a borrower is in trouble.
The break-even test
The simplest test divides the costs paid up front by the monthly saving. The answer is the number of months before the borrower has recovered the costs. If the loan will be kept longer than that, refinancing pays. If not, it loses money. The US Consumer Financial Protection Bureau uses this logic for paying points on a mortgage: in its example, $675 paid up front for a $14 monthly saving takes about 48 months to recover, and the bureau advises comparing total costs over the shortest, the longest and the most likely time the loan will be kept.
The gain is measured at a chosen date, the end of the period the borrower expects to keep the loan. It counts the balance still owed at that date on each loan, so a loan that has been paid down faster gets credit for it. The calculator below does not discount the cash flows to present value, which a careful analyst would add, but the break-even months and the direction of the answer are the same in most cases.
Test a refinance
The borrower owes $200,000 at 7.00% with 25 years left, a payment of $1,414 a month. Set the new rate, the new term, the costs paid up front as a share of the balance, and how many years the borrower expects to keep the loan. The left page compares the payments and the break-even. The right page compares the totals.
The current payment is $1,414 a month; the new loan's is $1,258, a saving of $155 a month, after $4,000 of costs. The costs are recovered after 26 months. If the loan is kept for 8 years, refinancing leaves the borrower $15,707 better off. Over the full terms, total interest and costs would be $181,464 on the new loan against $224,068 if the old loan runs on.
Five experiments. First, at the starting settings the new payment is $1,258 against $1,414, a saving of $155 a month for $4,000 of costs. The costs are recovered after 26 months, and over eight years the refinance leaves the borrower $15,707 better off. Second, shorten the stay to 3 years: the gain falls to $3,486. Raise the costs to 4% and cut the stay to 2 years and the break-even stretches to 52 months, so the borrower finishes $3,004 worse off. Third, change the new rate to 7.5%, above the current rate. The new payment is $1,478, higher than before, and the borrower finishes $11,971 worse off over eight years. Fourth, set the new term to 15 years. The payment rises to $1,661, so there is no monthly saving, yet total interest and costs over the new loan fall to $102,948 against $224,068 on the old one. Fifth, set the new term to 30 years: the payment falls to $1,167 and the monthly saving rises to $246, but total interest and costs over the new term are $224,172, about the same as if the borrower had stayed in the old loan.
Break-even months for different rates and costs, with a new 25-year term:
| Months to recover the costs, $200,000 at 7.00%, 25 years left | Costs 1% of the balance | Costs 2% | Costs 3% | Costs 4% |
|---|---|---|---|---|
| New rate 6.50% | 32 months | 64 months | 96 months | 127 months |
| New rate 6.00% | 17 months | 33 months | 49 months | 65 months |
| New rate 5.50% | 11 months | 22 months | 33 months | 44 months |
| New rate 5.00% | 9 months | 17 months | 25 months | 33 months |
A small rate cut with high costs can take over ten years to repay, while a large cut with low costs pays within a year. This is why an offer to "refinance for free" deserves a look at the rate it comes with: the costs may have been moved into a higher rate.
The term trap
The lowest payment comes from the longest term, and that is the tempting choice. A longer term spreads the same balance over more months, so each payment is smaller, but interest is charged for more months as well. The table fixes the new rate at 5.75% and the costs at 2% and varies only the term.
| Same 5.75% rate, costs 2%, kept 8 years | New payment | Monthly saving (brackets: costs more) | Interest and costs over the whole new term | Better off after 8 years |
|---|---|---|---|---|
| New term 15 years | $1,661 | ($247) | $102,948 | $25,985 |
| New term 20 years | $1,404 | $9 | $141,000 | $19,433 |
| New term 25 years | $1,258 | $155 | $181,464 | $15,707 |
| New term 30 years | $1,167 | $246 | $224,172 | $13,382 |
The payment and the total cost move in opposite directions. A 30-year term gives the biggest monthly saving and still costs about as much in total as the old loan, because the borrower is restarting a 30-year clock on a loan that had 25 years left. Shortening the term has the reverse effect: the payment goes up, and the interest saved is large. The right choice depends on what the borrower needs: a lower payment now, or a lower total cost. A borrower who takes the longer term but keeps paying the old amount repays early anyway, and has the lower required payment to fall back on in a bad month, if the loan allows extra payments.
Two companies that refinanced in 2025
Companies refinance for the same reasons, on a much larger scale. Energizer, a US consumer products company, and Samsonite, the luggage maker listed in Hong Kong, each announced a refinancing in the autumn of 2025. The table sets out what each said in its press release. Neither release is a complete record of the terms, and the table says so where a detail is missing.
| Debt refinancing, autumn 2025 | Energizer | Samsonite |
|---|---|---|
| Announced | 9 September 2025 | 3 November 2025 |
| New debt | $400 million of 6.00% notes due 2033, priced at par; $100 million added to a term loan at SOFR plus 200 basis points | Senior notes due 2033, a new term loan B and new senior credit facilities; the release gives no amounts |
| Old debt repaid | 6.50% senior notes due 2027, and the revolving credit facility | Not stated in the release, which points to the HKEX announcement for the terms |
| What the company said happens to maturities | Extends the debt maturity profile | Term loan A to 5 years, term loan B to 7 years, notes to 7.25 years |
| What the company said happens to interest cost | Expected to reduce interest expense; described as leverage neutral | Will not result in a significant change in cash interest expense |
Both extended their maturities, and they differ on the cost. Energizer replaced notes paying 6.50% that were due in 2027 with notes paying 6.00% that are due in 2033, so the coupon falls by half a percentage point, which is $0.5 million a year for every $100 million refinanced, and the first repayment date moves six years further away. The release does not give the amount of the old notes, and the premium paid to retire them early is a cost that reduces the saving. Samsonite said its refinancing would not significantly change its cash interest expense, so the gain is time: longer maturities mean it does not have to refinance or repay soon. Refinancing for time rather than for a lower rate is common. It reduces the risk that a company cannot roll over its debt when a loan falls due.
Restructuring: when the borrower cannot pay
Refinancing assumes the borrower is healthy enough to get a new loan on better terms. Restructuring is what happens when it is not. The borrower and its lenders agree, or a court decides, to change the terms of the debt because the original terms cannot be met. The changes can include a longer maturity, a lower interest rate, a reduction in the amount owed, or an exchange of debt for equity.
Lenders agree because of what they expect to recover. The lesson on credit risk defined loss given default. If a business is worth more kept running than broken up, lenders may recover more by accepting a smaller or later payment than by forcing a sale. In the United States, a company can reorganise under Chapter 11 of the bankruptcy code, where it keeps operating and restructures its debts, or be liquidated under Chapter 7, where a trustee sells its assets to pay debts. According to the US Securities and Exchange Commission's investor bulletin, creditors, including bondholders, suppliers and employees, all come before holders of common stock, and a reorganization plan often cancels the existing shares, with the new shares generally going to creditors. Other countries have their own insolvency laws, and the order and the details differ.
What these tests cannot tell you
- The stay is a guess. People move, sell and refinance again. The break-even only helps if the loan really is kept past it.
- The calculator ignores the time value of money. A saving next year is worth slightly less than the same saving today, and money freed by a lower payment can be invested.
- Costs differ. Some are fixed amounts, others a share of the balance, and some loans charge a penalty for repaying early, which the calculator does not include.
- Rates can be variable. If the new loan's rate can change, the saving today is not guaranteed.
- Company releases are summaries. They give the headline terms. The full cost of a refinancing includes premiums and fees that may not appear.
Common mistakes
Looking only at the new payment
A lower payment can come from a longer term, and the total cost may be higher. Compare total interest and costs too.
Ignoring the costs
A small rate cut may not cover the fees. Divide the costs by the monthly saving to see how long recovery takes.
Restarting the clock without noticing
Refinancing a loan with 10 years left into a new 30-year loan adds 20 years of payments.
Rolling the costs into the loan without counting them
Costs added to the balance accrue interest. They are still costs.
Assuming a refinance is always a good sign for a company
Refinancing can show lenders' confidence, or it can be a way of postponing a problem. Look at the new maturity, the cost and the reason.
Try it yourself
1. A refinance costs $5,000 and saves $125 a month. How many months to recover the costs, and what happens if the borrower moves after 3 years?
Show the working
Break-even = 5,000 ÷ 125 = 40 months. After 36 months the saving is 36 × 125 = $4,500, which is $500 short of the costs. Moving in the fourth year, before month 40, loses $500.
2. A $100,000 loan with 20 years left is refinanced from 6% to 5% over the same 20 years. Find the two payments and the monthly saving.
Show the working
At 6% (0.5% a month, 240 months) the payment is $716.43. At 5% it is $659.96. The saving is about $56.50 a month. A cost of $3,000 would take about 54 months to recover.
3. A borrower with $150,000 at 6% compares 15 and 30 years. Which has the lower payment, and which costs less in interest?
Show the working
The 15-year payment is $1,265.79 and the interest is about $77,841. The 30-year payment is $899.33 and the interest is about $173,757. The 30-year loan has the lower payment and more than twice the interest.
4. A company replaces $100 million of 6.50% notes with 6.00% notes. What is the yearly saving in coupon, and what could reduce it?
Show the working
The coupon falls by 0.50 percentage points, which is 0.5% × $100 million = $0.5 million a year. Costs such as the premium paid to retire the old notes early and the fees on the new ones reduce the saving.
5. In a company reorganization, who is paid first, bondholders or shareholders, and what often happens to the existing shares?
Show the working
Creditors, including bondholders, come before holders of common stock. A plan of reorganization often cancels the existing shares, and the new shares generally go to creditors.

Questions people ask
How much lower should the rate be before refinancing?
There is no fixed rule. The test is the break-even: the costs divided by the monthly saving, set against how long you expect to keep the loan.
Is it better to roll the costs into the new loan?
It avoids paying cash now, but the costs then earn interest for the life of the loan, so the total is higher.
Can I refinance if I have missed payments?
A weak payment record can make a lender decline or charge more. In that case the lender and borrower may talk about a restructuring of the existing loan instead.
What is the difference between refinancing and restructuring?
Refinancing replaces a debt with a new loan, usually from a position of strength. Restructuring changes the terms of an existing debt because the borrower cannot meet them.

How the numbers were checked: every payment, saving, break-even and gain was recomputed in plain code, the gain was also checked by rolling both loan balances forward month by month, and the calculator, which runs separately, was compared with that code across a grid of inputs.
