This balance transfer calculator helps determine whether consolidating high-interest credit card debt onto a card with a promotional 0% or low APR makes financial sense. The methodology compares the total interest cost of staying on your current card versus the cost of a balance transfer, accounting for the transfer fee (typically 3-5%) and any new interest that accrues during the promotional period. It calculates how much you would pay in interest on the old card over the same time period to determine net savings. Real-world use cases include deciding whether to do a balance transfer, choosing between multiple balance transfer offers, and determining how much to pay each month to eliminate the balance before the promotional rate expires. Key considerations include the length of the promotional period, whether the rate after promo is acceptable, the impact of new purchases on your payment allocation, and how balance transfer offers affect your credit score through hard inquiries and reduced credit utilization. Limitations include assuming you will not make new purchases on the card and not accounting for potential rate changes after the promotional period.
Result: Transferring an $8,000 balance from a 24% APR card to a 0% promo card for 18 months with a 3% transfer fee ($240 cost) saves approximately $2,160 in interest compared to paying the original card. With $500 monthly payments, you would pay off the balance in 18 months with $240 in fees but zero interest, versus $2,400 in interest on the original card.
