Look beyond the monthly repayment

A smaller repayment can still mean a dearer loan

The useful question is not only “What will I repay next month?” but “What will I repay in total, and when will it end?”

01

Monthly budget change

Shows the monthly breathing room—or added payment—created by the new loan.

02

Total cost modelled

Combines interest and the origination or transfer fee you entered.

03

Payoff speed

Compares time to zero balance, including a same-budget accelerated path.

04

Break-even APR

Turns the decision around: what loan APR would make the chosen term and fees stop saving money?

Method

How this UK debt consolidation calculator works

Every result comes from the figures you enter. No lender data, credit search or AI estimate is involved.

1

Map each debt

Enter the balance, APR and fixed monthly repayment from current statements.

2

Price the new route

Add the proposed loan APR, term, arrangement fee and how the fee is paid.

3

Simulate month by month

The calculator applies monthly interest, subtracts payments, and tracks balance and cost until payoff.

4

Stress-test the decision

Change the rate, term, fee, or payment and watch the totals, timeline, and break-even point move.

REAL-OFFER CHECK

Five checks before accepting a lower repayment

Use the results to prepare questions for a real UK offer—not as an approval or recommendation.

  1. Compare the loan's APR, not only its advertised interest rate.
  2. Confirm whether an arrangement fee is deducted, paid upfront or added to the balance.
  3. Check the total of payments and the exact number of months, not only the monthly bill.
  4. For a balance transfer, note the promotion end date, transfer fee, and post-promotion APR.
  5. Make sure the new repayment fits a budget that does not depend on new card borrowing.

Calculator basics

What does a UK debt consolidation loan calculator show?

It compares the modelled monthly repayment, time to clear the balance, interest and fees on your current borrowing with a hypothetical consolidation loan. It also shows first-year capital reduction, a same-budget payoff route and a break-even APR.

How accurate is this UK consolidation calculator?

It is an educational estimate based on the balances, APRs, repayments, fees and terms you enter. Actual credit agreements can use daily interest, variable minimum repayments, promotional rates, charges or rules that give a different result.

Does the free UK calculator store my borrowing details?

No. The calculator runs in your browser and does not submit, store or place your entries in a URL. Only the separate contact form sends information; never include account numbers or other sensitive details there.

Can I use this for £50,000 of debt?

Yes. Enter borrowing totalling £50,000 and test the APR, fees and term for the loan you are considering. The maths does not decide whether you qualify or which rate a lender may offer.

Is a bill consolidation calculator different?

The basic comparison is the same: several eligible balances and repayments are set against one proposed loan. Check that every bill or agreement can realistically be settled before including it.

Can I combine cards, overdrafts, loans and car finance?

You can model different rows, but the calculator only compares cash flow. Secured car finance, overdrafts and unsecured credit can have different rights, early-settlement charges and consequences that the maths does not capture.

Reading the result

Does a lower consolidation repayment always save money?

No. A lower repayment can result from a longer term and may increase the interest paid overall. Compare total cost, the payoff date and any fees, not only next month's repayment.

Why compare APR rather than only the interest rate?

APR expresses the yearly cost of borrowing and can make comparable loan offers easier to assess. Enter arrangement fees separately here because a lender may deduct, charge or add them to the balance in different ways.

What is a break-even APR for a consolidation loan?

It is the highest modelled loan APR that produces no greater combined interest-and-fee cost than keeping your current borrowing, at the selected term and fee. It is a mathematical threshold, not a quoted rate.

How do arrangement fees affect consolidation savings?

A fee increases the cost of the new loan straight away. If it is added to the modelled balance, interest can also be charged on it. Check whether a real lender deducts, adds or separately charges the fee before comparing offers.

Why does a balance show that my repayment does not cover interest?

The monthly repayment entered is less than or equal to that month's modelled interest, so the balance cannot fall under the fixed-repayment assumption. Check the statement values or increase the repayment in the scenario.

What does “keep the same monthly budget” mean?

It applies the total amount you now repay across your borrowing to the consolidation loan, even when the required repayment is lower. Keeping that budget can shorten the term and reduce interest.

Comparing options

How do I compare a 0% balance transfer with a personal loan?

Mark eligible card balances, then enter the transfer fee, promotional APR and duration, standard APR after the offer and your planned repayment. Compare that route with the fixed-rate loan on total cost, payoff time and monthly commitment.

Can this work as a credit-card refinancing calculator?

Yes. Enter one or more card balances as current borrowing and compare them with a personal loan. Use the actual APR, term and fees from the offer, and remember that using cleared cards again changes the outcome.

How do I model an unsecured consolidation loan?

Use the consolidation-loan fields for its fixed APR, term and arrangement fee. The calculator does not assess affordability, eligibility, variable-rate clauses or whether the loan is genuinely unsecured.

Can I use it for car-finance consolidation?

You can compare the repayment maths, but car finance may be secured on the vehicle. A replacement loan can change ownership, insurance, early-settlement and repossession considerations that this calculator cannot value.

What is a personal debt consolidation loan?

It is usually an unsecured personal loan used to settle several credit commitments, leaving one scheduled repayment. It can simplify things, but whether it is cheaper depends on APR, fees, the term and what happens to old accounts.

Is debt consolidation the same as a debt solution?

No. Consolidation normally replaces or combines borrowing while keeping the amount owed. Debt solutions such as a debt-management plan, IVA or bankruptcy have very different legal, credit and long-term consequences.

Next steps & limits

Will consolidating borrowing improve my credit score?

This calculator cannot predict a credit-score change. An application, a new account, repayment history, balances, account closures and later card use can affect UK credit files in different ways.

What if I cannot afford minimum repayments now?

Do not rely on a calculator alone. Contact your creditors promptly and use a free, confidential debt adviser. Be cautious of firms that promise instant relief or tell you to stop paying creditors.

Should I include a UK student loan?

Not as ordinary unsecured borrowing. UK student loans are normally repaid through income-contingent rules and have separate thresholds, write-off conditions and protections that this model does not reproduce.

Does the calculator compare a secured homeowner loan?

It can reproduce basic repayment maths, but it does not model valuation, legal costs, property risk or the fact that missed repayments on borrowing secured against your home can put it at risk.

What should I compare in a real UK loan offer?

Check the APR, amount borrowed, arrangement fee, monthly repayment, term, total amount repayable, early-repayment rules and whether fees are deducted or financed. Ask the lender about any figure that does not match your model.

What should I do after the calculator shows a saving?

Test a higher APR, a longer term and real fees; get settlement figures; check your budget; and compare the result with the lender's pre-contract information. A modelled saving does not guarantee acceptance or a better outcome.
