The Strategic Balance Transfer Planner
A 0% APR balance transfer can be a financial lifesaver—but only if you execute it correctly. This tool builds a battle plan by simulating both scenarios (with and without transfer) using the debt avalanche method to show you exactly how much time and money you'll save.

How This Calculator Works
Avalanche Method: This calculator uses the debt avalanche strategy, which prioritizes paying off debts with the highest interest rates first. You'll pay the minimum on all debts, then allocate any remaining budget to the highest APR debt until it's eliminated.
Max Transfer Calculation: The calculator automatically determines the maximum transfer amount by accounting for the transfer fee. For example, with a $5,000 limit and a 3% fee, you can transfer approximately $4,854 ($4,854 + 3% fee = $5,000). This ensures the total (transfer + fee) never exceeds your credit limit.
Month-by-Month Simulation: Both strategies (with and without transfer) are simulated month-by-month using daily interest accrual, minimum payment calculations, and avalanche extra payments. The results show total interest paid, months to payoff, and a visual timeline comparison.
3 Rules for Success
1. Don't Spend on the Transfer Card
The moment you use the balance transfer card for new purchases, you lose the 0% grace period. Credit card companies apply payments to the lowest APR balance first, so new purchases (typically at the high post-promo rate) will accrue interest immediately while your transferred balance remains at 0%.
2. Watch for the Boomerang Rate
If you don't pay off the transferred balance before the promo period ends, the remaining balance immediately starts accruing interest at the post-promo APR (often 24.99% or higher). This "boomerang rate" can erase your savings if you're not prepared. Set up automatic payments to ensure you're on track.
3. The 3% Rule: Make Sure It's Worth It
Generally, a 3% transfer fee is acceptable if you can pay off the debt within the promo period. If the fee exceeds 5% or your payoff timeline extends beyond the 0% period, the transfer may cost more than keeping the debt on your original card. This calculator helps you run the numbers before committing.
