Bankroll management is the habit that keeps betting affordable: set aside a fixed sum you can afford to lose, and size every stake as a small, pre-agreed part of it. It does not make bets win; it limits how much damage a bad run can do and stops stakes from growing out of control. This guide covers bankroll management, the common staking plans, the Kelly criterion and the variance that makes all of it necessary.

What Is Bankroll Management?

It starts with a betting fund kept separate from money you need, decided before any bet and never topped up to chase losses. Each stake is then a small share of that fund, so a losing run shrinks stakes rather than forcing bigger ones. If the fund runs out, the budget for that period is spent. That discipline matters more than any system.

Which Staking Plan Should You Use?

A staking plan is the rule for how much of the bankroll each bet risks. Flat stakes use the same amount every time and are the simplest to keep to. Percentage stakes use a fixed share of the current fund, so they shrink after losses. Edge-based plans, such as Kelly, stake more when the estimated edge is bigger. The best plan is one you will actually follow.

What Does the Kelly Criterion Do?

The Kelly criterion sizes a stake in proportion to your estimated edge and the odds, and in theory it grows a bankroll fastest over the long run. In practice it depends completely on the edge estimate being right, and small errors lead to overstaking. That is why many people who use it stake a fraction of what the formula says. The betting calculator sets out the formula with a worked example.

Why Do Good Approaches Still Lose Runs?

Variance is the natural spread of results around the average. Even a sound approach loses for weeks at a time, and a poor one can have a good month. That is why a small sample of results says little about skill, and why stakes sized by bankroll management survive the bad runs that variance makes inevitable.

Why Keep a Record of Every Bet?

Bankroll management only works if you know where the fund stands, so write down every bet: the stake, the price, the market and the result. A record shows whether stakes are drifting upwards after losses, which markets you actually do well or badly in, and how far results are from what the prices implied. The Acca Tracker keeps that record for accumulators.

A record also protects against the stories memory tells. Big wins are easy to remember and slow leaks are not, and only the full record shows which one describes your betting. Review it at set intervals, not straight after a result.

What Bankroll Management Cannot Do

No staking plan turns a losing approach into a winning one; it only controls the size of the swings. Treat any betting as entertainment with a budget. The guide to betting odds and value explains what an edge means, and the accuracy page shows how the TACTIX probabilities have matched results, losing picks included.
