Frequently asked questions

Avalanche or snowball — which is better?
Avalanche targets the highest rate first and costs the least interest. Snowball clears the smallest balance first for quick wins and momentum. Avalanche saves money; snowball can be easier to stick with.
What is the rollover effect?
When a debt is cleared, its minimum payment rolls into the next debt on top of your extra. The pool you put toward debt grows as you go, which is why payoff accelerates.
Why does it say my payments are too low?
If the minimums plus your extra do not cover the interest charged, the balances grow instead of shrinking. Increase a payment so progress is possible.
Is this financial advice?
No. These are estimates to help you plan and compare options. Your real figures depend on your lender, taxes and personal situation, so check with a qualified professional before deciding.
