What you've lost. In numbers.
You don't need to know your exact results. With how much you play and for how long, the bookmaker's math already says what it has cost you on average. It's not a prediction: it's the fixed price the business is designed to charge you.
The idea
Why time plays against you.
Every odds line carries a hidden margin.
When a bookmaker prices a match, it doesn't share out 100% of the probability: it shares out 105%, 110%. That excess is its margin, and it collects it on every slip, whether you win or lose. A single bet can go well. A thousand bets won't.
That's why the number that matters isn't what you stake once, but the total volume that passes through the bookmaker over time. You re-stake what you win, you come back next week, and the margin bites every time. Here you see it added up, in euros.
Work out what betting costs you
Answer two things and pick the type of bet you make most.
The total that passes through the bookmaker: what you deposit plus what you re-stake from winnings.
Count the ones behind you, or the ones you plan to keep going.

The money, played and replayed
-328 €
Of the 4,680 € that passed through the bookmaker, 7% stays on its side of the counter. That's 328 € that didn't come back — and not through bad luck, but by design.
At the same pace, over ten years
Keeping this pace for a decade costs around 1,092 €. The bookmaker doesn't need you to lose: it just needs you to keep playing.
Seen from the other side
That figure isn't a fee for a service. It's the profit the business extracts from you. The bookmaker doesn't bet against chance: it bets that you'll come back.
