Whatever you think of a match, one decision matters more than any tip: how much you put on it. Stake sizing decides whether betting stays a small part of enjoying football or turns into something that hurts. This guide is about keeping it small, planned and under control.

- Your betting budget is money set aside purely for betting, an amount you’re fine with losing in full.
- Think in units, a fixed small share of the budget such as 1-2%, not in dollars.
- Flat staking is the simplest and safest plan for most people.
- Percentage staking shrinks your stakes after losses. Kelly sizes them by your edge and needs care.
- Avoid plans that raise stakes after a loss, such as doubling up.
- Losing runs of 8-10 bets are normal. Plan for them before they happen.
Step one: decide the budget, separately from everything else
Your betting budget should be separate from rent, bills and savings, and small enough that losing all of it wouldn’t change your month. Many people pick an amount per month, like they would for a streaming subscription or a night out. When it’s gone, betting stops until next month. Don’t top it up.
Units: a common language for stakes
A unit is a fixed slice of the budget. With a $200 budget and a 1-unit stake of 2%, each standard bet is $4. Thinking in units:
- stops one emotional bet from blowing up the month;
- lets you compare results over time, whatever the budget;
- makes “I’ll put a bit more on this one” an explicit decision instead of an impulse.
Staking plans compared
Flat staking
Every bet gets the same stake, for example 1 unit. It’s easy to follow and hard to misuse, and losing runs drain the budget slowly. For most people, this is the right answer.
Percentage staking
Every bet is a fixed percentage of the current budget. After losses your stakes shrink automatically, so you can never quite lose everything. After wins they grow. The catch: a losing run followed by a winning run leaves you below where you started, because you were betting less on the way back up.
Kelly staking
Kelly sizes each stake by how big your edge is. It only makes sense if your probability estimates are genuinely reliable, and most people’s aren’t. If you use it, take a fraction (a quarter or half of the Kelly stake) and cap any single bet at a few percent. Our Kelly stake calculator shows the numbers.
| Plan | Simplicity | Protection on losing runs | Main risk |
|---|---|---|---|
| Flat (1-2%) | Very simple | Good | Very little |
| Percentage (1-2%) | Simple | Very good | Slow recovery after a dip |
| Fractional Kelly | Needs estimates | Depends on your inputs | Staking too much if you overestimate your edge |
| Doubling after losses | Simple | None | Stakes grow until the budget is gone |
Plans to avoid
- Doubling after a loss (the Martingale): six losses in a row at a $5 starting stake means your next bet is $320, just to win back $5. Long losing runs happen far more often than people expect.
- Chasing a target: “I’ll stop once I’m $100 up.” This turns a budget into a hole.
- Confidence stakes: putting 5 units on the bets you “really” fancy. How sure you feel about a bet is a poor guide to whether it wins.
Losing runs are normal: here’s how normal
Even a good bettor winning 53% of bets around 2.00 will, over a season of 500 bets, quite likely hit a run of 8 losses in a row at some point. Our simulations put it close to a coin flip. At 1-2% per bet, that’s a dip you can absorb. At 10% per bet, it’s most of the budget. Run your own season in the match simulator.
Risk of ruin in plain words
Risk of ruin is the chance your budget hits zero before your edge, if you have one, has time to show. It depends mainly on stake size. Small stakes keep it close to zero. Big stakes make it likely, even with an edge. Without an edge, betting long enough always ends at zero, whatever the plan. Staking controls the speed, not the destination.
Keep a simple record
A spreadsheet or notes app is enough: date, match, market, price, stake, result. Once a month, look at the total. Most people are surprised, and seeing the real number is the best protection against kidding yourself.
When to change your stakes
- Reduce straight away if betting starts to affect your mood, sleep or money.
- Recalculate your unit at fixed points, such as the start of each month, not after a big win or a bad night.
- Never raise stakes to recover losses.
Common mistakes
- No set budget, just “whatever’s in the account”.
- Raising stakes after a loss to win it back.
- Late-night or in-play betting after a drink.
- Adding extra legs to an accumulator to “make it worth it”.
- Not keeping records, so losses feel smaller than they are.
