Run long-term projections on the decisions shaping your plans to truly understand their impact:

  • Could I go part-time and still stay on track?
  • When will I reach Lean FIRE versus Coast FIRE?
  • Could I start a business without putting everything at risk?
Life-event scenario modeling

Model life's big decisions

Big decisions feel risky when you cannot see the trade-offs. Reduce uncertainty and enjoy turning real choices into events to see how timing, cash flow, and assumptions change your life and finances.

Compare cities before you move

Compare the life you want in a new city against the financial reality of leaving your current one.

  • Set the move date and one-time relocation costs.
  • Adjust income, rent, taxes, and recurring expenses.
  • Compare the Lisbon scenario against your current location.

Cash-flow rules and automation

Control the flow of your finances

Invest, save, or automate. Your money, your rules. Set custom triggers for your inflows and outflows to optimize your wealth. With Fignis, you dictate exactly where, when, and how your money moves, putting your financial growth on absolute autopilot.

Security

Built with security as a baseline

Fignis is used to model sensitive financial decisions, so we protect your data with strong encryption, hardened browser controls, secure authentication, account boundaries, disciplined operations, and a clear rule: we do not and never will sell your data.

Security
  • Externally tested web security Fignis scores A+ on SSL Labs and Security Headers, plus 10/10 on MDN Observatory. For you, that means the connection and browser rules around your planning workspace are tested against public standards for modern HTTPS, strong TLS, HSTS, restrictive content loading, MIME-sniffing protection, and careful cross-origin controls.
  • Strong encrypted connections Your browser connects to Fignis over HTTPS with a hardened TLS configuration, so the financial assumptions you enter are encrypted while they travel between your device and Fignis.
  • Hardened browser protections Fignis sends security headers that tell your browser which resources may load, where pages may be embedded, and how sensitive content should be handled, reducing the chance that another site can interfere with your planning session.
  • Secure access Fignis supports social login and email-based accounts, so you can sign in without sharing financial account credentials.
  • Database and data security Your planning data is separated by account in the application and database access layer, so it stays within the account it belongs to unless access is intentionally shared.
Custom financial scenario engine

Simple. Customizable. Powerful.

Build your financial scenarios your way. Mix predefined categories with your own custom rules, then reuse them anywhere. No more guessing. Just granular, deterministic simulations that turn complex financial forecasting into crystal-clear clarity.

Keep the whole plan in view.

Fignis keeps income, assets, debt, taxes, and life events in one scenario model so you can test major decisions with less manual work and more confidence.

Keep the whole picture connected

Income, assets, debt, taxes, and life events stay in one plan instead of being scattered across separate tools.

Compare scenarios without rebuilding

Start with your main scenario, create another path, and see what changes.

Make changes with more confidence

See how timing, cash flow, and long-term outcomes move together before a decision becomes expensive to unwind.
