Balance Transfer Calculator - Credit Card Savings

The balance transfer calculator compares the cost of paying off a credit card at the current APR with the cost of moving the balance to a transfer offer. It includes the transfer fee, monthly payment, intro APR period, and interest after the intro period so the savings estimate reflects both the promotional rate and the repayment plan. The formula is Savings = current-card payoff interest - (balance-transfer interest + transfer fee). The current card is amortized at the current APR. The transfer balance begins with the current balance plus any fee, accrues transfer APR during the intro period, and then uses the current APR after the intro months expire. A fee cap is applied when entered. Use the credit card balance transfer calculator when deciding whether a 0% APR promotion is worth the fee, whether the planned payment retires the debt before the intro period ends, or whether a lower transfer APR still saves money after fees. It is especially helpful for comparing offers with different fee percentages and intro lengths. The estimate assumes a fixed monthly payment and does not include new purchases, late fees, penalty APRs, minimum-payment recalculations, or card-specific allocation rules. If the transfer APR is promotional, confirm the go-to rate and transfer deadline in the card terms. The calculator provides a disciplined payoff comparison, but successful savings still require making the planned payments on time. The most important scenario is the payoff-before-promo case. If the monthly payment retires the full transferred balance during the intro period, the fee may be the only transfer cost. If the balance remains after the intro period, savings depend on the go-to rate and how quickly the remaining balance is paid. Compare several payment levels before applying, because a small payment increase can prevent months of post-promo interest. For best results, save the card offer terms, transfer deadline, fee cap, intro APR, go-to APR assumption, and payment plan with the output. Balance transfer savings are easy to overstate when new purchases or missed payments trigger different rules. A documented calculation helps borrowers decide whether the offer is a payoff strategy or simply a way to postpone the same debt.
