How Balance Transfer Calculations Work

  • Transfer fee: usually a % of the transferred amount (often 3%–5%), added to your balance
  • 0% promo period: interest is 0% during the promotional months
  • Required payment: \( \text{(transferred balance)} / \text{promo months} \)
  • Post‑promo APR: remaining balance starts accruing interest at the regular APR

This tool shows both the “pay it off in time” plan and what happens if you pay less than the required amount.

Tips to Avoid Post‑Promo Interest

  • Set autopay to at least the required monthly payment
  • Account for the transfer fee (it increases what you must pay off)
  • Don’t add new purchases to the transfer card unless you understand how your issuer allocates payments
