On a $5,000 credit card at 22% APR with a $100 minimum payment, paying only the minimum takes over 7 years to pay off and costs approximately $3,128 in interest — more than 60% of the original balance paid just in interest charges. Paying a fixed $300/month instead clears the same debt in under 2 years and costs only $480 in interest — a savings of $2,648. The debt avalanche method (highest interest first) minimizes total interest paid. The debt snowball method (smallest balance first) builds momentum through quick wins.
Avalanche vs. Snowball — Which Payoff Method Is Right for You?
Enter each debt: name, balance, interest rate, and minimum payment. Add any extra monthly amount available for debt payoff. Choose your strategy — avalanche (highest interest rate first) or snowball (smallest balance first). The calculator shows payoff order, exact debt-free date for each account, total interest paid under each strategy, and how much you save versus paying minimums only. Run both scenarios to compare the mathematical difference.
Frequently Asked Questions
Pay the minimum on all debts, then put all extra money toward the highest-interest-rate debt. Once that debt is paid off, the freed payment rolls to the next highest rate. This method minimizes total interest paid and is mathematically optimal for getting out of debt at the lowest cost.
Pay minimums on all debts, then put extra money toward the smallest balance regardless of interest rate. Quick payoffs create psychological wins that sustain motivation. Research shows people who need early victories to stay on track are more likely to complete debt payoff using snowball, even if it costs slightly more in interest.
On a $5,000 balance at 22% APR with a 2% minimum payment (starting at $100): paying only the minimum takes approximately 7.5 years and costs $3,128 in interest. Paying $300/month takes 19 months and costs only $480 in interest — a difference of $2,648 and 6 years of monthly payments.
Build a $1,000 starter emergency fund first (prevents new debt from unexpected expenses), then attack high-interest debt. Once high-interest debt is gone, build a full 3–6 month emergency fund. Always contribute enough to get any 401(k) employer match — it is an immediate 50–100% return that beats even 22% APR debt mathematically.
Debt consolidation can reduce your average interest rate and simplify payments into one monthly amount. It works when the consolidation loan rate is significantly lower than your current rates and you do not extend the repayment term so long that total interest paid increases. Always calculate total cost — not just monthly payment — before consolidating.
