What you can do

Thanks to the 30% partial exemption, you save on taxes.

How this was calculated

CAGR = (€15,000 ÷ €10,000)^(1 ÷ 5) − 1 = 8.45%

CAGR (Compound Annual Growth Rate) is the annual growth rate an investment would have needed to grow from an initial value to a final value, assuming profits are reinvested. It is the most important metric for comparing different investments over different time periods.

Several deposits and withdrawals: money-weighted return

For savings plans, top-ups and withdrawals: enter every payment with its date and, at the end, today's value. The result is the annual rate your money actually earned (internal rate of return).

Your money earned 4.95% per year

Paid in €12,000.00, paid out including today's value €15,000.00, gain €3,000.00.

Method: the rate is chosen so that the present value of all payments is zero – the same equation as the effective annual rate under Section 16 PAngV (annex). Assumption: one year = 365 days. Before tax, without inflation.
