Decision one
What changes the result most?
The new rate, the new term and whether lower monthly payments simply stretch the debt for longer. That is usually where the decision is won or lost.
Debt strategy
Debt consolidation savings calculator
Use this debt consolidation calculator to compare what you are paying now with what a consolidation loan would actually change. It shows how long repayment takes, what the debt costs in interest, and whether a lower monthly payment is a genuine improvement or just a longer route through the same problem.
What matters most
- The key outputs are payoff time, total interest and monthly payment change. Read all three together before deciding.
- A lower monthly payment only helps if the total cost still makes sense. If the term stretches too far, the debt can become more expensive overall.
- What to test next: lower payment versus lower total cost, separate debts versus one loan, and shorter-term pressure versus long-term drag.
Decision two
Where does the estimate flatter the plan?
A cheaper-looking monthly bill can still be a poor move if the term extends and total interest rises. A neat output can hide that until you push the inputs harder.
Decision three
What should you compare next?
Run the base case, then compare lower payment vs lower total cost, keep separate debts vs combine them, and shorter term strain vs long term drag. That usually tells you more than staring at one answer.
Before you calculate
Use this page to judge the strength of a consolidation plan before you sign up to it
This calculator is most useful when you treat it as a decision page rather than a formality. Enter the balances you actually want to replace, the rate you are paying now, and a consolidation loan you could realistically get.
You should then read the result in three layers: whether the new payment is genuinely easier to carry, whether the total interest falls, and whether the debt clears faster or simply takes longer in a tidier format. If the monthly payment drops but the overall cost rises, that is not a clean win.
Calculator
Run the numbers before you commit to a consolidation loan
Use figures you could keep up with in an ordinary month. The goal is to see whether consolidation reduces total cost, shortens the debt, or simply repackages it into a lower monthly figure that lasts longer.

Interpret the result
What your results mean
Read the monthly payment, total interest and payoff time together. Debt consolidation only improves the position if the new loan solves a real problem, not just the appearance of one.
How long is too long?
If the new loan runs for much longer than the debts you are replacing, the lower payment can come at a high price. A plan that stretches well beyond four or five years deserves extra scrutiny unless it is clearly reducing interest and making the debt easier to finish.
When is the debt still expensive?
If the consolidation loan still generates a large amount of interest relative to the balance, the debt remains expensive even if the payment looks tidier. A lower APR helps, but the term and any fees still decide the final cost.
What to do next based on the result
- If the new monthly payment is lower and the total interest also falls, consolidation may be doing exactly what you need.
- If the payment falls but total interest rises, test a shorter term before deciding. That often shows whether the deal is genuinely useful or just more comfortable in the short term.
- If the result is still expensive, compare other routes such as a balance transfer for card debt or a faster targeted repayment plan using avalanche or snowball methods.
Worked example: keep current debts vs consolidate
Suppose you have £12,000 of debt at an average 24.9% APR and you are paying £360 a month now. At that pace, the debt clears in about 4 years and 5 months and costs about £6,940 in interest.
Now compare that with a consolidation loan for £12,000 at 11.9% APR over 4 years, plus a £250 fee added to the loan. The new payment is about £322 a month, the loan clears in 4 years, and the total interest and fee cost is about £3,206.
That cuts the repayment time by about 5 months and reduces borrowing cost by roughly £3,734.
When to take further action
If you are only covering minimum payments on cards, using credit for food or bills, carrying several balances that keep shifting around, or seeing almost no progress after months of paying, it is worth stepping back. In that situation, review lower-interest options, simplify the number of repayments you are juggling, and consider a broader debt strategy instead of treating consolidation as the only answer.
What this result does not do for you
- A lower monthly payment does not automatically mean a better deal if the term stretches and the total cost climbs.
- The estimate assumes you can actually get the quoted loan, at the quoted rate, with the fee structure you entered.
- Combining debts can simplify the plan, but it only works if you avoid rebuilding the balances you just cleared.
- Treat the result as a decision tool, not a promise of lender approval or future behaviour.
Repayment strategies worth comparing
- Consolidation loan: usually strongest when you can secure a clearly lower APR and want one fixed payment. The drawback is that a longer term can still increase the total cost.
- Balance transfer: often stronger for credit card debt if you can get a good 0% period and clear the balance before the rate resets. The drawback is that transfer fees and the end of the offer matter.
- Avalanche or snowball repayment: useful when you do not want a new loan or may not qualify for one. The drawback is that the monthly strain often stays higher in the short term.
Compare next
Compare the options that change the outcome most
Put these side by side and focus on the trade-off you will actually feel each month and over the full term.
Consolidation loan
Best when: You can get a materially lower APR and want one fixed payment instead of several moving parts.
Main drawback: A longer term can make the monthly payment look better while increasing total interest.
Balance transfer
Best when: Most of the debt is on credit cards and you can clear a large share of it during a 0% period.
Main drawback: Eligibility, transfer fees and the follow-on rate all matter. If progress is slow, the benefit can fade quickly.
Avalanche or snowball repayment
Best when: You want to avoid new borrowing or a consolidation quote does not improve the numbers enough.
Main drawback: The monthly pressure often stays higher because you are not stretching the debt into a new loan.
What this page cannot decide for you
It cannot predict lender approval, the exact APR you will be offered, or whether your wider spending pattern makes consolidation sustainable. Use it to rule out weak deals, not to assume any loan with a lower payment is a good one.
How to use the result well
Run three versions: the deal you are considering, a shorter term that pushes harder on total cost, and a non-consolidation alternative. If one option lowers the payment, reduces the interest and still clears the debt on a sensible timeline, you have a stronger basis for a decision.
FAQ
Debt consolidation savings calculator questions people actually ask
Does a lower APR always mean I’ll pay less overall?
No. The new APR matters, but so do the term and any fee added to the loan. A consolidation loan can carry a lower rate and still cost more overall if you stretch the repayment period too far. Always compare monthly payment, total interest and payoff time together.
Why does the calculator treat my debts as one balance?
It gives you a clear first comparison between your current position and a single consolidation loan. That is usually enough to show whether the idea has merit. If your debts have very different rates, use a weighted average APR here, then check the most expensive balances separately if you want a tighter view.
What if my current monthly payment changes each month?
This tool assumes a fixed total monthly payment so you can compare one clear scenario with another. If your payments usually drift because you are making card minimums, the real payoff time on your current debts may be even longer than the model shows. In practice, that often makes consolidation look slightly stronger than a minimum-payment habit, but not necessarily stronger than an organised repayment plan.
How is the consolidation monthly payment calculated?
It uses a standard fixed-rate loan formula based on the APR and term you enter. If you add a fee, the model treats it as financed within the new loan balance. That mirrors how many UK personal loan quotes are presented, but always check whether a real lender collects the fee upfront instead.
Should I include overdrafts and BNPL?
You can include anything you genuinely want to clear or replace, as long as the total balance and average APR still reflect reality. Overdrafts and some buy now, pay later balances can make sense to include if they are part of the debt pressure you are trying to solve. Just be careful not to assign interest where none is currently charged.
Will the calculator tell me if my payment is too low?
Yes. If your monthly payment does not exceed the first month’s interest, the balance will not reduce and the tool will stop and prompt you to adjust your inputs.
