About this app

DebtVest is an educational finance calculator that helps you compare debt repayment and investing scenarios using your own assumptions.

Model different strategies, including paying down debt first, investing first, or using a hybrid approach.

DebtVest helps you visualise how loan balance, interest rate, surplus cash flow, lump sums, investment returns, income yield, tax settings and time horizon may affect long-term outcomes.

DebtVest can help you explore questions like:

- Should I put extra money toward my mortgage or invest it?
- What happens if I split surplus cash between debt and investing?
- How could different return assumptions affect the result?
- How long might it take to pay down debt under different scenarios?
- What is the potential trade-off between lower interest costs and investment growth?

Key features:

- Debt repayment vs investing scenario modelling
- Hybrid strategy comparison
- Investment growth and income yield assumptions
- Tax-aware modelling by supported region
- Offset and lump sum scenario inputs
- Monte Carlo style uncertainty modelling
- Clear charts and comparison outputs
- Educational explanations and assumptions

DebtVest is designed for people who want a clearer way to think through debt and investing trade-offs before speaking with a qualified professional.

Important: DebtVest does not provide financial advice, investment advice, tax advice, lending advice or credit advice. Results are hypothetical and based on the information and assumptions you enter. Actual outcomes may differ. You should consider your own circumstances and seek advice from a licensed financial adviser, tax professional or other qualified professional before making financial decisions.
