Step-by-Step Guide
How to calculate the profit and return of a stock investment step by step: 1. Enter the purchase data: purchase price per share, number of shares, transaction costs (order fee). 2. Enter the sale data: sale price and order fee. 3. Add dividends: all gross dividends received during the holding period. 4. Calculate the gross profit: (sale price - purchase price) x number of shares + dividends - fees. 5. Calculate taxes: price gains and dividends are subject to 26.375 % withholding tax (incl. Soli). Deduct the saver's allowance (EUR 1,000). Losses on shares can only be offset against gains on shares. 6. Determine the net profit and return. Example: Purchase of 100 shares at EUR 45 = EUR 4,500, order fee EUR 10. Sale at EUR 62 = EUR 6,200, order fee EUR 10. Dividends: 3 years x EUR 1.50 x 100 = EUR 450. Gross profit: 6,200 - 4,500 + 450 - 20 = EUR 2,130. Taxable: 2,130 - 1,000 = EUR 1,130. Tax: 1,130 x 26.375 % = EUR 298. Net profit: EUR 1,832. Return p.a. (3 years): approx. 11.5 %.
Calculation Example
100 shares, purchase at 45 EUR, sale at 62 EUR after 3 years. Dividends: 450 EUR. Gross profit: 2.130 EUR. Tax (after the tax-free allowance): 298 EUR. Net profit: 1.832 EUR. Return: about 11,5 % p. a.
