Payoff estimate if debts are consolidated at the entered rate.

Review the assumptions behind the result.

  • The model compares three debts using minimum payments plus one flexible extra repayment.
  • Lump-sum payments are applied immediately according to the chosen strategy.
  • The behavioural score favours strategies that create early visible wins.

Turn the output into a practical next step.

  • Choose avalanche if the cheapest path matters most.
  • Choose snowball if early wins help you stay consistent.
  • Use consolidation only if the rate and payment discipline improve the overall plan.
