The solver finds the portfolio and monthly saving needed for this first withdrawal. It does not try to spend the portfolio down by a chosen end date.

Optional for an income goal. Enable it only to see how the portfolio and percentage payout may develop after the first withdrawal.

Withdrawal strategy

Withdrawal rate ?

%/yr

Converted to an equivalent monthly percentage of the current balance. Income follows the market and can fall sharply after losses.

Goal withdrawal strategy 4.0 %/yr Set under Your goal. The payout remains a percentage of the current portfolio, so it can rise or fall.

Withdrawal phases ?

Smooth compounding at your assumption – useful for comparison, not a market forecast.

During saving

Replay one observed return sequence for the complete saving phase.

Expected annual return after ongoing product costs ?

%/yr

Volatility ?

%/yr

Index / asset ?

A US equity index, chosen because its history is the longest available here - long enough to replay a 30-year plan without assuming a return for the rest. Its monthly figures average each month's daily closes rather than taking the last one, which slightly softens the highest and lowest points.

Historical period ?

Uses the latest matching historical window.

Starts – Ends –

The window length always matches your saving phase. Move the complete period without changing its length.

Chart comparison ?

Best and worst are the observed outcomes for your savings plan, not probability bounds.

Past the last observation

Most plans run longer than the price history behind them. These months are projected, not replayed.

After saving ends

Historical replay needs a separate return assumption for retirement.

Retirement return ?

Custom retirement return

–

This is a smooth retirement projection after the observed replay. Use Monte Carlo to explore retirement sequence risk.

Backtest vs. Monte Carlo: A backtest replays observed returns in their original order. Monte Carlo creates many synthetic return sequences from an assumed return and volatility, then reports percentile ranges.

Market episodes ?

Stress-test sequence risk while keeping the smooth plan as your baseline.

Inflation ?

%/yr

Capital-gains tax ?

Simplified comparison only: a rate of 27.5 percent is applied to gains realised on sale using an average cost basis. Austrian fund taxation, reported distributions and distribution-equivalent income, and the broker’s actual KESt withholding are not modelled.

Advanced tax details

Church tax ?

9 % in most states, 8 % in Bavaria and Baden-Württemberg.

Yearly tax-free allowance ?

€

1,000 single · 2,000 jointly assessed. Resets every year; what you do not use is lost.

Vorabpauschale ?

Basiszins, published each January. 3.20 percent for 2026; it was negative in 2021 and 2022, which charged nothing. Over 30 years the rate you assume matters far more than any published one.

Which gains a withdrawal realises ?

Sells your oldest shares first, as German law prescribes. They carry the biggest gains, so early withdrawals are taxed harder and later ones more lightly.
