Debt Consolidation Loans: When They Save You Money and When They Don't (Calculator)

Quick answer: A debt consolidation loan saves you money when its interest rate, including any fees, is clearly lower than the average rate on the debts you are replacing, and when you repay it at least as fast as you would have repaid those debts. With US credit cards charging about 22% on accounts that carry a balance and 24-month personal loans averaging about 12% in 2026, according to the Federal Reserve, consolidating $11,000 of card debt into a three-year loan at 12% saves about $2,400 in interest and cuts the monthly payment by about $67. It does not save money if the loan comes with a big fee, if you stretch the repayments over many more years, or if you run the cards up again afterwards, which is the most common way consolidation goes wrong. The calculator below shows the break-even loan rate for your own debts.

Most pages about debt consolidation are written by lenders that want you to take out a loan. This guide sets out, neutrally, when consolidation helps, when it does not, and what the alternatives are, with a calculator that compares both options over the same repayment period, so a lower monthly payment cannot hide a higher total cost.

Both options assume you repay everything over the same number of months with fixed monthly payments, so the comparison is fair. If you only make minimum payments on cards, clearing them takes far longer and costs much more interest. APRs are annual rates; average US credit card rates on accounts paying interest were about 22% in 2026 and 24-month personal loans about 12% (Federal Reserve). Not financial advice.

What Debt Consolidation Is

Debt consolidation means replacing several debts, usually credit cards, store cards, overdrafts or "buy now, pay later" balances, with a single new loan. The main options are:

Three credit cards at 22% to 29% combined into a single loan at 12%
Consolidation replaces several expensive debts with one loan and one payment.
  • An unsecured personal loan with a fixed rate and a fixed term, typically one to seven years. This is the most common form.
  • A balance transfer credit card with a 0% introductory rate for 12 to 24 months, usually with a transfer fee of 3% to 5%.
  • A secured loan or remortgage, borrowing against your home. Rates are lower, but your home is at risk if you cannot pay, and stretching unsecured debt over 20 years can cost far more in total.
  • A debt management plan arranged through a non-profit credit counselling service, which negotiates lower interest with your creditors without a new loan.

When Consolidation Saves Money

Three conditions need to be met:

  1. A lower rate. The loan's APR, which includes compulsory fees, should be well below the weighted average rate on your current debts. The calculator shows the highest APR that still saves money.
  2. The same or a shorter repayment period. A loan at 12% over five years can cost more in total than cards at 22% repaid in three, even though the monthly payment is lower.
  3. No new debt. If you clear your cards and then use them again, you end up with the loan and new card balances. Many advisers suggest closing or lowering the limits on the cleared cards, although closing old accounts can slightly reduce your credit score.

A Worked Example

Take three debts typical of many households: $6,000 on a credit card at 24%, $3,500 on another at 22% and $1,500 on a store card at 29%, $11,000 in total.

Total interest on $11,000 of card debt: $4,550 over three years on cards against $2,150 with a 12% loan
Interest and fees on $11,000 of credit card debt under different repayment plans.
  • Repaying the cards over three years with fixed payments costs about $432 a month and about $4,550 in interest.
  • A three-year consolidation loan at 12% costs about $365 a month and about $2,150 in interest. Saving: about $2,400.
  • The same loan with a 5% arrangement fee added: about $384 a month and $2,810 in interest and fees. Saving: about $1,740.
  • The same loan over five years: only about $245 a month, but about $3,680 in interest, so the saving shrinks to about $870, and you are in debt for two more years.
  • Paying only the minimum on the cards (3% of the balance a month) would take about 26 years and cost more than $21,000 in interest.

The lesson: the rate matters, but the repayment period matters just as much. Choose the shortest term you can comfortably afford.

Current Rates in 2026

  • United States: the Federal Reserve's G.19 survey shows an average rate of 22.15% on credit card accounts that were assessed interest in the second quarter of 2026, and 11.86% on 24-month personal loans from commercial banks. Rates rose slightly this year as the Fed raised interest rates. Individual offers depend heavily on your credit score: borrowers with excellent credit may be offered single-digit APRs, while those with fair credit may be offered 20% or more.
  • United Kingdom: Bank of England figures put the average interest rate on credit card balances at about 24.7% in early 2026, the highest in more than 30 years, while personal loans of £7,500 to £10,000 are available from around 6% to 7% for good credit, with higher rates on smaller loans.
  • Other countries: card rates of 15% to 25% are common in Canada and Australia, 30% to 45% in India, and far higher in Brazil, where revolving card debt can carry annual rates above 400%.

If rates continue to rise, fixed-rate consolidation loans lock in today's rate, while card rates, which are mostly variable, would rise further. Our guide Interest Rates Are Rising Again: 7 Money Moves to Make Now explains how rising rates affect borrowers.

Balance Transfer Cards vs Personal Loans

For smaller balances that you can clear within the interest-free period, a 0% balance transfer card is often cheaper than a loan:

Timeline of a 0% balance transfer: 18 interest-free months, then the rate jumps above 20%
A balance transfer is cheapest if you clear the debt before the 0% period ends.
  • Transferring $5,000 with a 3% fee costs $150. If you clear it within an 18-month 0% period, at about $286 a month, that is the total cost.
  • The risk is the end of the 0% period. Any balance left reverts to the card's standard rate, often over 20%. Some cards charge interest backdated to the start if you miss a payment.
  • Balance transfer cards usually require good credit, and the limit you are offered may not cover all your debts.

Personal loans are better for larger balances, for people who want a fixed end date, and for those who might be tempted to keep spending on a card.

Effect on Your Credit Score

Applying for a loan triggers a hard credit check, which may lower your score slightly for a few months. After that, consolidation often helps: paying off card balances lowers your credit utilisation, one of the biggest factors in most scores, and a record of on-time loan payments adds to your history. Use eligibility checkers that do a "soft search" before applying, so you do not collect several hard checks. Our guide Why Is My Credit Score Different on Every App? Which One Do Lenders Actually Use? explains how scores are calculated.

Warning Signs and Alternatives

Be wary of:

  • Companies that charge upfront fees to "settle" or "consolidate" your debts. In the US, debt settlement firms are not allowed to charge fees before they settle a debt, and in the UK debt advice is available free from charities.
  • Loans much longer than your current debts, which lower the monthly payment but raise the total cost.
  • Secured loans for unsecured debt, which put your home at risk.
  • Payment protection or insurance add-ons sold with the loan, which raise the cost.

If you are struggling to make payments, a loan may not be the answer. Free, independent help is available from non-profit credit counselling agencies in the US (look for members of the National Foundation for Credit Counseling), StepChange, Citizens Advice and National Debtline in the UK, and similar services in other countries. They can set up debt management plans, negotiate with creditors and explain options such as insolvency. Our guide How to Pay Off Credit Card Debt Fast compares the avalanche and snowball methods for paying off debts without a new loan.

Step by Step: How to Consolidate

  1. List every debt with its balance, rate and minimum payment.
  2. Check your credit score and use soft-search eligibility tools to see the rates you are likely to be offered.
  3. Use the calculator to compare the best offer with repaying your debts directly over the same period.
  4. Choose the shortest term you can comfortably afford, with no or low fees and no early repayment penalty.
  5. Use the loan to pay the debts off in full straight away; some lenders pay creditors directly.
  6. Set up a direct debit for the loan, and make a plan for the cleared cards so balances do not build up again.
  7. Keep a small emergency fund so an unexpected bill does not go back on a card. Our guide How Much Emergency Fund Do You Need? (With Calculator) shows how much to keep.

Frequently Asked Questions

Is debt consolidation a good idea?

It is a good idea if the new loan's APR is clearly lower than your current debts, you repay it at least as quickly, and you do not build up new debt. It is a bad idea if it mainly stretches your debt over a longer period or comes with high fees.

Does debt consolidation hurt your credit score?

The application may cause a small, temporary dip. Over time, lower card balances and on-time loan payments usually improve your score.

What is a good interest rate for a debt consolidation loan?

Any rate that is well below the average rate on your current debts, after fees. In 2026, the US average for a 24-month personal loan is about 12%, while borrowers with excellent credit can find lower rates.

Can I consolidate debt with bad credit?

Possibly, but rates offered to borrowers with poor credit can be as high as the cards you are replacing, so the saving may be small or negative. A debt management plan through a non-profit agency may be a better option.

Is a balance transfer better than a consolidation loan?

For balances you can clear within the 0% period, usually yes, even after a 3% to 5% fee. For larger balances or longer repayment periods, a fixed-rate loan is often safer.

How long does debt consolidation take?

Applying for a loan can take minutes to a few days, and the funds can arrive within a day. The repayment period is up to you, usually one to five years.

Final Thoughts

Debt consolidation is a tool, not a cure. Used well, it turns several expensive, variable-rate debts into one cheaper, fixed payment with a clear end date, and can save thousands in interest. Used badly, it stretches debt out for years and frees up cards to be filled again.

Before you sign, compare the total cost over the same period with the calculator, choose the shortest term you can afford, and have a plan to keep the cleared cards clear. If repayments already feel unmanageable, talk to a free debt advice service first.
