Wealth Projection

Calculator purpose

Use this dashboard to separate assets, liabilities and investable capital before comparing debt repayment, investment or a FIRE target.

How It Works

This dashboard combines three tools in one: a Net Worth calculator (Assets − Liabilities), a FIRE tracker (using the 4% Rule), and a Liability Optimiser (comparing your debt cost vs. expected investment return). All calculations happen in your browser — no data is stored.

Worked Example

Worked Example: 330 000 € of assets less 150 000 € of liabilities equals 180 000 € net worth; with 1800 €/month of expenses, the indicative FIRE target is 540 000 €.

Frequently Asked Questions

What is Net Worth?▼

Net Worth = Total Assets − Total Liabilities. It is the most fundamental measure of personal financial health. A positive and growing net worth means you are building wealth.

What is the FIRE Number?▼

Your FIRE Number = Annual Expenses × 25. It is a planning convention based on a 4% withdrawal rate, not a guarantee. Local example: with 1800 €/month (21 600 €/year), the indicative target is 540 000 €.

Should I pay down my mortgage or invest?▼

If your expected investment return (e.g. 7% S&P 500) exceeds your mortgage rate (e.g. 3%), investing the surplus generates more wealth over time. However, paying down debt gives a guaranteed, risk-free return equal to your interest rate. Your risk tolerance and time horizon matter.

What are Lean, Regular, and Fat FIRE?▼

Lean FIRE = retiring on a minimal budget (70% of current expenses). Regular FIRE = maintaining your current lifestyle. Fat FIRE = retiring with a comfortable surplus (150% of current expenses). Each requires a different portfolio size.

What counts as investable assets?▼

Investable assets are liquid or semi-liquid assets: your investment portfolio (ETFs, stocks) and cash savings. Property equity is real wealth but is illiquid — it is included in Net Worth but not in the FIRE calculation, which focuses on income-generating assets.
