About this app

Plan your financial freedom with the most advanced ETF calculator in the store!

Want to know how your portfolio would have performed under real-world conditions? Looking for a calculator that takes into account not only simple interest rates but also German tax law (investment tax reform)?

Our app combines precise mathematics with an elegant "glass morphism" design to offer you the best user experience for your financial planning.

Highlights at a glance:

Historical backtesting: Use real market data from 1980 to the present day. Test your strategy with indices like the MSCI World, S&P 500, Nasdaq 100, DAX, or even Bitcoin and gold.

Tax expert: As one of the few apps, we calculate the advance lump-sum tax, partial exemptions (for equity, mixed, or real estate ETFs), and capital gains tax including the solidarity surcharge and church tax.

Individual withdrawal plans: Don't just calculate the savings phase, plan your retirement directly. How long will your capital last with a monthly target withdrawal?

Dynamic savings rates: Adjust for inflation or salary increases by increasing your savings rate by a percentage each year.

Interactive charts: Visualize your wealth growth. Compare invested capital with the net final value in high-resolution graphics.

Modern design: Enjoy an intuitive interface in dark mode with stylish glass effects.

Why this calculator?

Most calculators use a smooth average return (e.g., 7%). However, reality is volatile. With our historical backtest, you can see how crises and boom periods would actually have affected your final capital.

Features for professionals:
Adjustable tax-free allowance (€1,000 / €2,000 for married couples).

Consideration of fund costs (TER).

Portfolio Mix: Create your own asset weightings for your backtest.

Take control of your finances now and simulate your path to wealth building!
