Bankroll Management: Deciding What to Spend Before You Play

“Bankroll management” sounds like something for professional poker players. In reality it is a simple discipline anyone can apply: deciding in advance how much money you are prepared to lose, and structuring your play so that a bad run doesn’t take more than that.

Start with money you don’t need

The bankroll is money set aside purely for entertainment — the same category as a cinema ticket or a night out. It is never rent, bills, savings or borrowed money. If losing the full amount would cause a problem, the amount is too high.

Many people find it useful to set a monthly figure and divide it into sessions. A £60 monthly budget might become four £15 sessions; if one session goes well, the surplus is a bonus rather than an invitation to increase the next.

Size stakes to the session, not the game

The most common error is staking too large a fraction of the session budget. On a high-volatility slot, a stake of 1/20th of your budget gives you 20 spins — nowhere near enough to reach the game’s average feature frequency. A useful rule of thumb:

  • Slots: stake no more than 1% of the session budget per spin (a £20 budget means 20p spins).
  • Blackjack or roulette: 2–5% per hand or spin, since the variance per bet is lower.

Since April 2025, UK online slots have a legal maximum stake of £5 per spin (£2 for players aged 18–24), which removes the very top end of stake sizes, but sensible sizing is still your responsibility below those caps.

Set a stop-loss and a stop-win

A stop-loss is the point at which you close the game — usually the session budget itself. A stop-win is less intuitive but equally useful: a level (say, double the session budget) at which you withdraw and finish. Without one, wins tend to be re-staked until they become losses, because the house edge applies to every additional bet.

Use the tools the casino provides

UK-licensed operators are required to offer deposit limits, and since October 2025 must prompt every new customer to set one before their first deposit. Setting the limit to your monthly figure removes the decision from the moment of play, when judgement is weakest. Loss limits and session reminders do a similar job.

Keep a simple record

Note the date, the amount deposited and the amount withdrawn. Over a few months this gives a true picture of what your play costs, which memory tends to distort. Most account pages have a transaction history that does this automatically.

What bankroll management doesn’t do

It doesn’t change the house edge or the RTP. Over a long enough period, the expected result of any casino play is a loss roughly equal to stake × house edge. What management does is make that loss predictable, keep it within an amount you’ve chosen, and let you enjoy the time in between.

The one-line version

Decide the number before you log in; stake small enough to play for as long as you intended; leave when you hit either limit.
