Bankroll Management for Bettors: Unit Sizing, Staking and Downswings

Express stakes in units rather than currency. A unit is a fixed fraction of your starting bankroll — commonly 1%, sometimes up to 2% for bettors confident in their edge, less for beginners. A 2,000 bankroll at 1% units means a standard bet is 20.

Thinking in units keeps your staking proportional and stops you chasing. A losing day is "down four units", not "down 80", which is easier to keep in perspective.

Flat staking bets the same currency amount every time, recalculated occasionally. It is simple and its results are easy to read, but it does not adjust as your bankroll moves.

Percentage staking bets a fixed fraction of your current bankroll, so stakes shrink automatically during a downswing and grow as you recover. It compounds gains and cuts losses faster, at the cost of never quite recovering to the same stake without winning first. Most disciplined bettors use flat staking within a session or week and resize units periodically.

Even a genuine 55% bettor at even money will have losing runs of eight or ten in a row over a long enough sample. A 2% edge over 500 bets still finishes below zero a meaningful share of the time. This is not a sign the edge is gone — it is variance doing exactly what the maths says it will.

The practical defences are a big enough bankroll relative to your unit, stakes that do not balloon after losses, and a written plan you follow when you are tilted rather than one you invent mid-slide.

It depends on your edge and your variance, not just your edge. A low-variance approach needs fewer units of bankroll for the same risk of ruin than one chasing long-shot multipliers. As a rough floor, many bettors want at least 100 units before betting 1% stakes, and treat anything under 50 units as under-rolled for the stakes.
