Q1: How accurate is this calculator?
A: It provides a good estimate assuming fixed payments and interest rate. Actual payoff may vary if your balance, payments, or rate changes.
Q2: Why make extra payments?
A: Extra payments reduce principal faster, saving you money on interest and shortening payoff time significantly.
Q3: What if I can't make extra payments?
A: The calculator works with E=0 to show standard payoff time. Even small extra payments make a big difference over time.
Q4: Should I pay off highest APR cards first?
A: Yes, targeting highest interest debt first (avalanche method) typically saves the most money.
Q5: How can I pay off debt faster?
A: Increase payments, reduce expenses, or consider balance transfers to lower APR cards if possible.
