How Prosper Works

Prosper is a personal financial simulator. Instead of only tracking past spending, it helps you model what happens next across retirement, debt, investing, and household decisions.

1. Build your financial model

Set age, retirement assumptions, salary, costs, and expected annual growth. Then add assets, liabilities, and custom cashflows.

2. Run realistic scenarios

Compare base, optimistic, and stress cases. Test major events like financed purchases, expense changes, or different retirement timelines.

3. Decide with confidence

Use projections, snapshots, and household aggregation to evaluate tradeoffs before making long-term commitments.
