Debt costs the most when you only pay the minimum. These calculators show how long a balance takes to clear, how much interest you pay and how extra payments change that.
They also cover the ratios lenders look at, such as debt-to-income and credit utilization.
The minimum is often just above the monthly interest, so the balance barely falls. The payoff calculator shows the real timeline.
The avalanche method (highest interest first) costs the least, while the snowball method (smallest balance first) can be more motivating. The debt payoff calculator compares both.
Many lenders prefer to see usage below about 30% of your limit, and lower is generally better.
