How this calculator works
Each month, interest accrues on the outstanding balance at one twelfth of the APR. Your payment first covers that interest; the remainder reduces principal. As principal falls, the interest charge shrinks, so a larger share of every payment chips away at the balance.
This is why the early years of a high-rate balance feel like standing still — and why even modest payment increases produce outsized savings.
When to look beyond payoff
If your calculated payoff stretches beyond 5–7 years, or if the minimum payment barely exceeds interest, you may be a candidate for consolidation, settlement or — in severe cases — bankruptcy. Read our primers and reviews before contacting any company.
