In the UK show Dragon's Den, one-quarter ownership of a company is represented by a 25% stake.
A percentage stake describes the proportion of a business owned by an investor or founder. One quarter of the whole is 25 percent, so a Dragon receiving 25% equity would own one-quarter of the company immediately after the agreed transaction, subject to the deal's legal terms.
This calculation is central to the programme because entrepreneurs often request a specific amount of money for a stated percentage. For example, asking for £50,000 for 25% implies a pre-money valuation of £150,000 and a post-money valuation of £200,000 under standard assumptions.
A stake is not the same as a percentage of turnover. Ownership can bring voting rights and a share of future value, while revenue-sharing arrangements follow different rules. The programme's negotiations may change the percentage from the entrepreneur's opening offer.
