Compare moving a card balance to a 0% deal, with its fee, against staying put and paying it down where it is.
How it works and an example to tryShow less
How to use the result
Interest on staying is simulated month by month at the current APR. Moving adds the fee to the balance; anything left when the promo ends is charged at the go-to rate. The payment to clear at 0% divides the moved balance by the promo months.
Example to try
Moving £4,500 from 24.9% to a 24-month 0% deal with a 3% fee costs £135 and saves about £1,390 of interest at £200 a month. Paying £193 a month clears it before the promo ends.
