Rates & sources
A user-entered payoff schedule. It adds the entered balance-transfer fee to the balance and uses the entered promotional duration and later APR; it does not list offers, assess eligibility or recommend borrowing.

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.
Balance to transfer (£)
3500
Transfer fee (%)
3
0% promotional period (months)
6
After entering these figures, review transfer fee, balance after fee and monthly payment to clear together rather than in isolation — each metric tells a different part of the story. Then rerun the tool with one input adjusted to see which variable has the biggest effect on all three outputs before you settle on a plan.
How to read your results
Transfer Fee
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.
Balance After Fee
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.
Monthly Payment to Clear
Use this to check whether the scenario fits comfortably within your regular budget. If it looks tight, rerun the tool with a longer term or larger deposit to find the boundary of affordability.
Method & assumptionsAuthoritative sources
This planner makes a balance-transfer deadline concrete. It adds the entered transfer fee to the balance, shows the even monthly amount needed to clear it during the entered 0% period and estimates the balance left if you follow a different monthly payment.
If a balance remains, it uses the post-promotion APR you enter to illustrate a further payoff path. That illustration does not replace the card agreement, minimum-payment rules, fees, credit-limit rules or an affordability assessment.
Never rely on a future balance-transfer offer. Keep required payments up to date and seek free independent debt advice if the plan is not affordable rather than taking additional borrowing.
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.
