Monthly budget change
Shows the monthly breathing room—or added payment—created by the new loan.
Your route planner
Build the comparison from your real statements
Enter fixed monthly repayments you can realistically keep making. The model assumes no new borrowing and a constant APR.
Add your cards, overdrafts and loans, test a consolidation loan, and see whether a lower repayment saves money—or only extends the term.

Look beyond the monthly repayment
The useful question is not only “What will I repay next month?” but “What will I repay in total, and when will it end?”
Shows the monthly breathing room—or added payment—created by the new loan.
Combines interest and the origination or transfer fee you entered.
Compares time to zero balance, including a same-budget accelerated path.
Turns the decision around: what loan APR would make the chosen term and fees stop saving money?
Method
Every result comes from the figures you enter. No lender data, credit search or AI estimate is involved.
Enter the balance, APR and fixed monthly repayment from current statements.
Add the proposed loan APR, term, arrangement fee and how the fee is paid.
The calculator applies monthly interest, subtracts payments, and tracks balance and cost until payoff.
Change the rate, term, fee, or payment and watch the totals, timeline, and break-even point move.
REAL-OFFER CHECK
Use the results to prepare questions for a real UK offer—not as an approval or recommendation.

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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
