Debt Calculators
Build a realistic payoff plan with snowball, avalanche, consolidation, and debt-to-income tools.
Getting out of debt is mostly arithmetic plus consistency. These calculators turn vague balances into concrete payoff timelines so you can pick the strategy you'll actually stick with.
The snowball method (smallest balance first) wins on motivation; the avalanche method (highest APR first) wins on total interest. For most people the right answer is whichever one they'll keep doing every month for two years.
Use the payoff calculator to see your timeline at your current payment, then experiment with small payment increases — even $50 more per month often cuts months off the schedule and hundreds of dollars off the total interest.
