Find the break-even point for a balance transfer

Price the transfer

Calculate the transfer fee and whether it is added to the new balance. Record the promotional APR, exact end date, eligible balance type, required minimum, and rate after promotion.

Keep purchase behavior separate. New purchases may have a different rate or grace-period treatment.

• Transfer amount
• Transfer fee
• Promotion end
• Post-promotion APR
• Planned payment

Test completion risk

Compare the old and new schedules at the planned payment. Then model a lower payment and remaining balance at the promotion end. Include any annual fee and the time the transfer takes to post.

Do not stop paying the old account until the transfer is confirmed and the next required amount is known.
