List the debts you want gone
Enter each balance, APR, and required payment. The payoff order only works if the starting picture is honest.
Monthly payment
Choose the monthly push
Even small extra payments can shorten the timeline because freed-up payments roll forward.

Payoff insight
The math favours interest discipline
Avalanche
Jan 2029
Highest-rate debts get the extra payment first. Usually the cheapest path.
Extra-payment focus order: Travel Rewards Visa -> Store Card -> Personal Loan
Snowball
Feb 2029
Smallest balances get the extra payment first. Often easier to follow emotionally.
Extra-payment focus order: Store Card -> Travel Rewards Visa -> Personal Loan

Planning inputs
Payoff assumptions to keep visible
These assumptions explain why the payoff timeline moves.- Highest APR
- 24.9%
- Current minimums
- $515
- Promo APR (%)
- Yes
High-rate debts drive the cost of waiting.
Minimum payments are treated as fixed amounts unless the balance is smaller.
Promo APR is used first, then the debt returns to its base APR.

What This Debt Strategy Tool Helps You Decide
Debt payoff is not only about the mathematically cheapest sequence. This tool shows the financial difference between strategies while still making the payoff order transparent enough to support real-world execution.
- Compares snowball and avalanche payoff schedules using your actual balances, APRs, minimums, and extra payment budget.
- Supports promo-rate debt so temporary balance-transfer offers do not get flattened into one generic APR.
- Shows payoff order, payoff date, sensitivity scenarios, and per-debt interest differences.
- Helps separate emotional execution preferences from the strictly lowest-interest plan.
FAQ
What is the difference between snowball and avalanche?
Snowball prioritizes the smallest balance first to create faster wins. Avalanche prioritizes the highest interest rate first to minimize interest cost.
Why include promo APRs?
Because temporary rates can change the most efficient payoff order for a period of time, especially on transferred credit-card balances.
When might snowball still make sense?
If the cost gap is small but the simpler payoff order makes it more likely you will stay consistent, snowball can still be a rational behavioral choice.
