Debt payoff & simulators

Track what you owe and compare payoff strategies like snowball and avalanche.

Debt payoff

Fullness helps you see your full debt picture and choose a payoff strategy that fits.

Add your debts

Linked loans and credit cards appear automatically. Add anything else manually with its balance, interest rate and minimum payment.

Compare strategies

  • Snowball — pay smallest balances first for quick wins and momentum.
  • Avalanche — pay highest-interest debts first to minimize total interest.

The payoff simulator shows your debt-free date and total interest under each strategy, and how extra payments accelerate things.

Stay on track

Fullness reminds you of upcoming payments and celebrates milestones as balances fall.
