When to use this calculator

  • Before comparing personal loan or credit offers on the same amount and term.
  • When you want to see total interest, not only the monthly payment.
  • When you are choosing between a shorter term and a lower monthly debit.
  • When you need a planning estimate before making a credit application.

After entering these figures, review transfer fee, balance after fee and monthly payment to clear together rather than in isolation. Then rerun the tool with one input adjusted.

How to read your results

Transfer Fee

The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.

Balance After Fee

The figure produced by this output for the inputs you entered. Change one variable at a time if you want to see what drives it.

Monthly Payment to Clear

Estimated amount paid each month under the selected APR and term. It is not a guaranteed offer.

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

  • !Judging an offer by the monthly payment alone and ignoring total interest.
  • !Using a representative APR as if it were a guaranteed personal rate.
  • !Forgetting arrangement fees or early-settlement terms.
  • !Comparing two loans that do not use the same amount and term.

What to do next

  • Compare offers using the same amount and term, then check total repayable.
  • Add fees and read early-settlement terms before treating the estimate as the full cost.
  • Test a shorter term to see whether a higher payment is worth the interest saved.
  • If several debts are involved, use a consolidation or payoff planner next.

Frequently asked

Not necessarily. A transfer fee is often added to the balance. Use the actual fee and period from an offer you can obtain, then compare it with your repayment plan.
