Your guided projection

Let’s make the numbers yours.

Step 1 of 7 · Invested 1 of 7

How much have you already invested?

Include investments that should grow as part of this plan. Cash for emergencies can stay outside it.

€0 Starting fresh–your first investment is still ahead. €10,000 Example: an ETF balance built over your first few years. €50,000 Example: an established portfolio you keep invested.

My amount Enter the current market value of your investments. €

How should we illustrate growth?

These are smooth planning assumptions–not forecasts. Real returns jump around and can stay negative for years.

Capital-stable 2% per year Example: an instant-access savings account or fixed-term deposit. Think steadier value, but rates change and may trail inflation. Illustrative–not a quoted bank offer Broadly diversified 7% per year Example: a long-term planning rate for broad global equities such as FTSE All-World or MSCI World. Both are still equity-only. Planning range 5–7% Growth-oriented 10% per year Example: an optimistic US large-cap assumption. The S&P 500 is concentrated in one market, so this is not a broad-world expectation. Compare 7% and lower. Stress-test 7% too

Custom My assumption Use your own nominal annual return and compare at least one lower case later. %/yr

What does the history actually say?

Cash-like products

“Tagesgeld” is an instant-access or call savings account; “Festgeld” is a fixed-term deposit. In June 2026, the German household aggregates were 0.51% overnight and 2.16% for new fixed terms up to one year. Their January 2000–June 2026 averages were 0.72% and 1.69%. Individual offers vary.

MSCI World: a longer view

MSCI World covers large- and mid-cap stocks across developed markets. MSCI reports data through June 2026 and warns that pre-launch data are back-tested and past performance is no guarantee. The 7% choice is an illustrative planning rate; compare 5% and lower too.

Why 10% is an upside case

10% is an optimistic illustration, not a forecast. The official S&P page describes the index as 500 leading US large-cap companies covering about 80% of available US market capitalisation. That is one market, so compare 7% and lower rather than treating 10% as a baseline.

Would you like to model retirement too?

You will always see a potential monthly income at saving end. It is a net estimate: tax on the realised-gain part has already been subtracted. Turn retirement on to simulate the actual payouts and remaining portfolio.

Yes, continue into retirement Example: 25 years means exactly 300 monthly withdrawals, beginning when saving ends. Each amount adapts to the portfolio. Not yet–show saving only The result still estimates potential income immediately after your last saving month.

What retirement would model 4% per year–not each month

Contributions stop and monthly withdrawals begin. The planner converts the 4% annual depletion into a 0.34% monthly share of the portfolio’s current value, so income can rise or fall with the market.

Withdrawal rate Adjusts both potential income and simulated retirement payouts %/yr

7% smooth return 4% dynamic yearly rate ≈2.7% nominal balance growth

With a perfectly smooth 7% return, the modeled balance still grows about 2.7% a year after withdrawals, before inflation.

A long-term average is not a safety guarantee. Inflation reduces purchasing power, realised-gain tax reduces take-home income, fees are not modelled, and poor early returns can reduce both payouts and the remaining portfolio. Every payout shown here is net: the selected estimated tax is subtracted from only the gain realised by that sale. The classic 4% rule fixes the first year’s euro amount at 4% of the starting balance and then adjusts it for inflation; this model recalculates from the current balance every month.

Set the final assumptions

Choose how the projection handles purchasing power and estimated tax on realised gains.

Inflation Used for every “today’s money” value

%/yr

Why 2%? It matches the ECB’s medium-term target and is a neutral planning baseline, not a forecast. Actual inflation can stay higher or lower for years, so compare a 2.5% or 3% case before relying on the result. ECB target ↗

Estimated tax on realised gains

Pick the closest treatment. This rate applies only to the profit realised when investments are sold–not to the whole payout or account value.

German equity fund · 18.46% Default. For a qualifying equity fund, 30% of gains are exempt and the remaining 70% uses the 26.375% standard rate. Church tax and allowances are not included. German standard · 26.38% 25% capital-income tax plus the solidarity surcharge, with no fund exemption or church tax. No estimated tax · 0% Use only when gains are genuinely exempt, offset or fully covered by allowances (€1,000 per person or €2,000 jointly in Germany).

Another effective rate For another country, church tax or your own tax estimate. %

FIFO remains the planning method: oldest shares are treated as sold first. Personal allowances, losses and church tax can change the real result. Country-specific fund taxation and broker withholding are not modelled by a custom rate. Existing starting wealth is treated as having no embedded gain because this short guide does not ask for its purchase cost. 25% tax rule ↗ Solidarity surcharge ↗ Fund exemptions ↗

Your first projection

Here is where this path could lead.

Net worth when saving ends

– – invested by you

In today’s purchasing power

– After the selected inflation assumption

If everything were sold

– Nominal value after estimated gains tax

Potential monthly income

– Net, in today’s money–estimated tax on realised gains has already been subtracted
