Which calculator do you need?
Credit card debt: start with the minimum payment calculator — seeing the honest timeline is usually the moment the plan changes. Several debts? The snowball vs. avalanche comparison runs both strategies on your real balances and gives a verdict with the dollar difference.
Installment loans: the student loan payoff calculator shows what an extra monthly amount does to your date, the auto loan calculator computes the real payment with trade-in and sales tax, and the personal loan calculator exposes what the origination fee does to the money you actually receive.
For the national numbers — payoff times and costs at the current average APR, by balance and rate — see our credit card minimum payment statistics, computed against Federal Reserve data.
