Worked example
A $5,000 transfer with a 3% fee adds $150. At 0% promotional APR and a $500 monthly payment, the transferred amount can be repaid during a 12-month period in this simplified model. The original path at 24% APR accumulates estimated interest.
Break-even estimate
The displayed break-even month divides the transfer fee by the first month's estimated interest difference. Because balances decline, this is only a quick orientation—not a precise future date.
