Rates & sources
An educational, local-only guide based on broad UK debt-priority categories. It never creates a personal payment order, advises stopping a payment or replaces urgent free independent debt, housing or legal advice.

When to use this calculator
- Before comparing lenders, brokers, or repayment options.
- When you want to test how a different deposit, rate, or term changes affordability.
- When you need a quick estimate before using a formal quote or agreement in principle.
- When you are stress-testing your budget against a potential rate rise to see the impact on monthly payments.
- When you want to understand the full cost of borrowing — not just the monthly figure — before you commit.
A realistic UK planning example
Use these sample inputs as a quick scenario test, then change one variable at a time to compare outcomes.
Rent, mortgage or secured-home payment
Not selected
Council Tax or Rates
Not selected
Gas or electricity bill
Not selected
After entering these figures, focus on core payments selected first and then rerun the tool with a more cautious assumption to understand the realistic range of outcomes rather than relying on a single estimate.
How to read your results
Core Payments Selected
Use this metric to compare scenarios side by side and understand how changes in the key inputs drive the final outcome. If the figure surprises you, isolate one variable at a time and rerun the calculation to identify which assumption is responsible.
Method & assumptionsAuthoritative sources
This local-only triage follows the broad distinction in independent UK debt guidance between urgent or priority payments, essential household bills and other credit or service payments. It asks only which categories you are worried about; it does not ask for balances, account details or a payment amount.
For each selected category, the tool prompts early contact with the relevant organisation and highlights when free independent debt advice is urgent. It deliberately does not tell a person to miss, stop or reduce a payment, because notices, legal rights, household circumstances and creditor arrangements matter.
If there is a court date, bailiff action, eviction or repossession risk, disconnection or other urgent enforcement concern, seek free independent debt advice promptly. Use the budget and debt planners to organise figures after immediate support is in place.
Common mistakes
- !Mixing up loan amount and property value, which can distort affordability and LTV.
- !Using a headline rate but forgetting fees, insurance, taxes, or repayment type.
- !Testing only one term length instead of comparing the payment and total cost together.
- !Forgetting that a repayment mortgage and an interest-only mortgage produce very different monthly figures and total costs.
- !Not accounting for the impact of a rate revert after an introductory fixed period ends, which can sharply increase payments.
What to do next
- Run a second scenario with a higher rate or shorter term so you can see the downside clearly.
- Compare the result with an affordability or overpayment calculator before applying.
- Use the related guides below to understand trade-offs before you request live quotes.
- Note down the monthly payment and total interest for your two or three strongest scenarios so you have a clear comparison ready when you speak to a broker.
- Check whether making a modest overpayment each month would reduce total interest significantly — run the overpayment calculator next to find out.
