The selection is only half the equation. How much you stake — and how consistently you apply a staking discipline — determines whether a profitable set of selections actually produces a profitable bank balance. Most punters spend the majority of their analytical time on which horse to back and almost none on how much to stake. That imbalance costs more than it should.
The Starting Point: The Betting Bank
A betting bank is a ringfenced sum of money set aside specifically for betting — separate from living expenses, savings, and any other financial purpose. The size of the bank determines the unit stake, and the unit stake determines how long a losing run can be absorbed before the bank is gone. Setting a betting bank that is genuinely separate from other finances is the prerequisite for any staking plan to function correctly. Betting from a blurred general account, where money flows in and out for other purposes, makes it impossible to track performance or apply a consistent unit size.
A standard starting bank for recreational punters is 50 to 100 units — where one unit is the standard stake per bet. If the bank is £500, the unit is £5 to £10. If the bank is £1,000, the unit is £10 to £20. The unit size should be small enough that a losing run of ten to fifteen selections does not eliminate a significant proportion of the bank.
Level Stakes
Level stakes is the simplest and most transparent staking method. Every selection receives the same stake — one unit — regardless of the odds, the confidence level, or the perceived strength of the case. Over a large enough sample of selections, level stakes produces a clear, honest measure of whether the selections are profitable. A tipster or system running at a positive return on investment on level stakes is demonstrably producing value. One that requires variable stakes to show a profit is obscuring the underlying performance.
For punters following a daily NAP service, level stakes on every selection is the recommended starting approach. It allows genuine performance tracking across a meaningful sample before any more sophisticated staking is applied.
Percentage Staking
Percentage staking — backing a fixed percentage of the current bank rather than a fixed unit — has the effect of automatically scaling stakes up during winning runs and down during losing runs. If the bank grows to £600 and the percentage is 2%, the stake becomes £12 rather than £10. If the bank drops to £400, the stake becomes £8. The bank is mathematically protected from ruin because the stake shrinks as the bank shrinks.
The limitation of percentage staking is that recovery from a losing run is slower than with level stakes. A bank reduced to 50% of its starting value requires a 100% increase to return to the original level — and the stakes during that recovery period are smaller, making the climb back longer. For most recreational punters, the protection it offers is worth that trade-off.
The Kelly Criterion
The Kelly Criterion is a mathematically optimal staking formula that adjusts the stake based on the perceived edge in each bet — backing more heavily when the edge is larger, less heavily when it is smaller. Applied correctly, it maximises the long-term growth of the bank. Applied incorrectly — with overconfident edge estimates — it produces dramatic variance and can devastate a bank quickly.
For most punters, full Kelly staking is too aggressive. Half Kelly — staking half of what the formula recommends — captures much of the mathematical advantage while significantly reducing the variance. It requires an honest estimate of the true edge on each selection, which is the most demanding part of the approach.
The Practical Rule
Start with level stakes. Track performance over a minimum of fifty selections before adjusting. If the selections are demonstrably profitable on level stakes, consider moving to percentage staking for the downside protection. Never increase stakes during a losing run to chase losses — that is the single most common and most damaging staking error in recreational betting.
