Imagine you and three mates buy a coffee cart. It costs £4,000, so you each put in £1,000 and own a quarter. At the end of the year, after wages, beans and the council's cut, the cart has made £2,000 profit.
You have a choice. Keep it all in the cart to buy a second grinder, or pay some out. You decide to keep £800 for the grinder and split the remaining £1,200 four ways. £300 lands in your account. That £300 is a dividend.
You didn't work a shift. You didn't sell your quarter. You still own it, and next year, if the cart does well again, there's another £300, or more, or less. That's the entire concept. A public company is the coffee cart with several million owners.
The three words you'll see
What it looks like in real life
Here's one of mine, with the real numbers. Legal & General paid 15.74p per share in June 2026. I owned 126,000 shares. Fifteen-ish pence times 126,000 is £19,830, and that's what landed. It goes in the ledger the day it lands, not the day it's announced.
You will not start there. I didn't. The first one was pocket money and I was thrilled. The number isn't the point at Level 0; understanding where it came from is.
