1 What Is a Betting Bankroll?
Your bankroll is the total amount of money you have set aside to wager. It is money you are prepared to lose as it has no effect on your finances.
Your bankroll is not your entire bank account. You do not use your bankroll to replace money you lost from other activities later on. Your bankroll is the total amount of money you are wagering on sports events.
Without a defined bankroll, you cannot determine how much to wager on any specific sporting event. You may place emotional stakes on events you feel strongly about or that you think will help recover a loss. This is the reason that most recreational punters lose more than they should.
2 Setting Your Starting Bankroll
The starting bankroll should be considered entertainment money. This money should not come from your budget as it would cause stress if you lost it all. It should also not be too much to start with as this could significantly affect your behavior towards betting.
Recreational bettors
If you are betting on sports events such as AFL, horse racing, and football throughout a full season, your starting bankroll should be the total value of the entertainment you will receive from these sports. Starting with this amount will give you the best chance of enjoying the sports without losing your entire bankroll.
Most recreational punters start with a bankroll of between $200 and $1,000 for a full season of betting on sporting events. There is no perfect amount for anyone as the perfect bankroll is one that you can afford without affecting your finances. For punters who bet only occasionally rather than maintaining a standing balance, no account betting sites allow single bets without holding funds on deposit.
Regular and systematic bettors
If you have a systematic approach to betting and keep proper records, your betting bankroll should be large enough to smooth out the losing and winning bets you will place. A minimum bankroll of 50 to 100 units will allow you to weather losing bets without running out of money too soon. If your unit is $10 each, then you will need to start with at least $500.
3 Unit Sizing - How Much to Bet per Wager
A unit is the amount of money you will stake on every bet. You will express this as a percentage of the total amount of your betting bankroll. You will place the same number of units on every bet.
Conservative approach: 1-2% per bet
The most common unit percentage for both recreational and systematic bettors is 1% to 2% of the total bankroll. With a $500 starting bankroll, 1% is $5 per bet and 2% is $10 per bet.
$500 bankroll at 1% = $5 per bet
$1,000 bankroll at 2% = $20 per bet
$250 bankroll at 1% = $2.50 per bet
If you place 1% units on every bet, you will have 82% of your money left after 20 losing bets. However, if you use 5% unit stakes on every bet, you will have only 36% of your original bankroll left after 20 losing bets. The lower the unit percentage, the more bets will be required before you run out of money.
Aggressive approach: 3-5% per bet
Using 3% to 5% units is only appropriate for those with an edge in the betting market and a large enough bankroll to absorb the losing bets. Using a high percentage of your bankroll for stakes will cause your bankroll to grow quickly if you have winning bets but will also lose quickly during losing bets. This system is not for beginners.
4 Staking Methods Compared
There are three main methods of determining your betting stake sizes for each sporting event.
Flat staking
Flat staking requires that you place the same amount of money on every sporting event you bet on. For instance, if your bankroll is $500 and you place $10 on every bet, you will continue to place $10 on every next sporting event. This method is the simplest form of staking. However, it does not allow for gains from winning bets to be compounded nor will losing bets reduce the amount of money you have to stake on the next event.
Percentage staking
Percentage staking requires you to determine the percentage of your bankroll that you will stake on each sporting event. If you have a $500 bankroll and you are placing 2% on every bet, your stake will be $10. If your bankroll increases to $600, then your stake will automatically be $12. If your bankroll drops to $400, then your stake will automatically reduce to $8. This system compounds the gains in your bankroll and allows you to lose less money with losing bets.
Variable staking / confidence weighting
Variable staking requires that you increase the amount of money you place on each sporting event based on the degree of confidence you have in the outcome. The problem with this system is that you must accurately assess your level of confidence in each event. It is difficult and possibly misleading as you may place higher stakes on events you feel strongly about rather than those with a higher chance of occurring.
Staking Methods at a Glance
| Method | How it works | During winning streak | During losing streak | Best for |
|---|---|---|---|---|
| Flat staking | Same dollar amount every bet | No change in stakes | No change in stakes | Casual and recreational bettors |
| Percentage staking | Fixed % of current bankroll per bet | Stakes grow automatically | Stakes reduce automatically | Systematic and value bettors |
| Variable staking | Stake scales with perceived confidence | Depends on bet selection | Depends on bet selection | Experienced bettors with quantified edge only |
| Martingale (avoid) | Double stake after every loss | Small gains | Bankroll destruction | No legitimate use case - avoid |
5 Stop-Loss Rules and Session Limits
A stop-loss is used to define the maximum amount of money you will lose in a betting period, after which you stop betting until the next period. This stops you from chasing your losses, which is the most common problem for bettors.
Daily and weekly limits
A stop-loss can be defined as a maximum amount of money you will lose during a specific time period such as a week. For instance, if you define a stop-loss of 10% of your total bankroll per week, and you reach that amount lost before the end of the week, you will cease to place any more bets until the following week. There will always be more events to bet on.
If you lose $150 by Wednesday, betting stops until Monday.
The bankroll resets to $850 at the start of the new week and the next weekly limit is $127.50 (15% of $850).
Withdrawal marks
A withdrawal target is the amount you want to grow your bankroll to before withdrawing the profit. When you reach that amount, you can withdraw the difference between your current bankroll and the starting bankroll. This prevents you from losing the profits you have made. It allows you to exit betting with a gain rather than the risk of losing it on the next sporting event.
Not chasing losses
Chasing losses is when you increase the amount of money you wager on a sporting event after losing money on the previous event. This is the most common way people lose all of their betting money. The next sporting event has no knowledge of what happened in the previous event. The chance of winning each sporting event is the same regardless of how much money you have lost. Placing a higher stake on an event you would not normally bet on does not change the chance of winning.
Some bookmakers offer a cash out feature that lets you settle bets early and lock in a return when a position moves in your favour - a useful tool for protecting a winning position before an event finishes. Our comparison of cash out betting sites covers which operators have the best cash out functionality.
6 Tracking Your Bets and Monitoring ROI
Keeping a record of the sporting events you bet on is the only way to determine if your betting activities are providing you with a profitable return. You can also use this record to determine if you have better results on specific sporting events.
What to record
For every sporting event you place a bet on, you should make a record of the date, the event, the sporting market, the selection, the bookmaker, the odds you took, and the outcome. You can also record whether the odds you took on each event were better or worse than the closing odds for that event. This will show you if your betting activities have genuine value.
What to calculate
Calculate the return on investment (ROI) for your betting activities. The ROI is calculated by dividing the total profits or losses by the total amount of money staked. The ROI will be represented as a percentage. If your ROI is a positive percentage over a large number of bets (200 or more), your betting strategy is providing you with a profitable return. An ROI of between 3% and 5% is considered to be strong for most punters. A negative ROI indicates that your betting strategy is not working.
Example: Total staked $2,000, total return $2,120.
ROI = ($2,120 - $2,000) / $2,000 x 100 = +6%
How many bets before your data is meaningful
Fewer than 100 bets will not give you a clear indication of the profitability of your betting activities. Between 200 and 500 bets provides a better understanding of your ROI. Below 100 bets, the outcomes of your betting activities can be the result of luck. You should not make any betting decisions based on fewer than 200 bets.
7 Common Bankroll Mistakes and How to Avoid Them
Most of the problems experienced in sports betting can be traced to a few common causes. By recognizing these causes in advance, you can avoid the betting mistakes.
Betting too large a proportion of your bankroll on multis
The temptation of placing a five-leg betting multi with high odds on each leg is strong. The chance of winning all five legs is the product of the chance of winning each individual leg. For example, if each leg of the five-leg multi has a 55% chance of winning, the chance that you will win all five legs is only 0.55 x 0.55 x 0.55 x 0.55 x 0.55, or 0.05, or 5%. While it is fine to place your standard betting unit on a five-leg multi, placing 20% of your bankroll on a five-leg multi is not.
Betting your favourite team
Placing a stake on your own sporting team creates a bias that makes you believe the chances of your team winning are higher than they should be. This does not mean that you should never place a bet on your own team. However, if you are placing a bet on your team, you should be just as critical of it as if you were placing a bet on the opposing team.
Increasing stakes without increasing edge
After a winning betting run, punters tend to increase the amount of money they place on the next sporting event. They then decrease their stake after losing events. This means they end up staking more money on events that have the same probability as any bet they placed before the run began. Your unit size should only change when your bankroll changes or when your documented edge justifies it - not because of recent results.
No records, no accountability
The only way to properly evaluate the success of your betting activities is to keep records of every sporting event you place money on. A punter who does not keep records will only remember the winning bets they have placed. Their memory may be biased toward these winning bets. By keeping accurate records, they will have an accurate understanding of the returns on their betting activities.
Frequently Asked Questions
What percentage of my bankroll should I bet per game?
Between 1% and 3% of your bankroll is the most common percentage range recommended for most bettors. At 1%, a punter would have 82% of their money left after 20 losing bets. At 3%, they would have 54% left after 20 losing bets. These percentages are a starting point for those without a defined betting edge. Starting at 1% to 2% is the most sustainable starting percentage for all punters without a defined betting edge.
What is a unit in sports betting?
A unit is the amount of money that is placed on every sporting event that you stake on. This amount is a percentage of your total bankroll. If you have a total bankroll of $500 and place 2% on every event, then each unit is $10. Using units for your betting stakes makes it easy to compare the different bets you place relative to your total bankroll. It also makes it easy to change the amount of money you place on each sporting event based on changes in your total bankroll.
What is the difference between flat staking and percentage staking?
Flat staking is when you place the same amount of money on every sporting event. With percentage staking, the percentage of your bankroll that you stake on every event is automatically calculated. The advantage of percentage staking is that your stakes will increase with winning bets and decrease with losing bets. With flat staking, you will always place the same amount of money on every sporting event. Flat staking is simple, but percentage staking is the mathematically better system for systematic bettors.
What is a stop-loss and should I use one?
A stop loss can be defined as the maximum amount of money that you will lose during a betting period, after which you will cease to place any more bets. For instance, if you define a stop loss of 10% for your bankroll each week, then if you have lost 10% of your total bankroll by Wednesday, you will cease to place any more bets until the following Monday. Stop losses are used as a way of avoiding the emotion-driven behavior of chasing losses.
How do I know if my betting is actually profitable?
Create a spreadsheet to keep track of the sporting events that you bet on. For each sporting event, record the date, the event, the odds you took, the stake, and the outcome. You can also calculate your return on investment (ROI) by dividing the total winnings or losses by your total amount staked and multiplying the result by 100. If you have a positive ROI based on a minimum of 200 sporting events, then you are making a profitable return. Fewer than 200 bets is too few to draw any conclusions about your betting strategy.
What is the Martingale system and should I use it?
The Martingale betting system is when an individual doubles the stake after every loss. The theory is that when they eventually win one of their bets, they will have gained enough money to recover all their previous losses. The flaw in this system is that an individual will eventually experience losing streaks of 7, 8, or 10 or more events in a row. For instance, if the initial stake is $10, after 7 losses, the stake will be $1,280. The Martingale system has no legitimate use case in sports betting.
Responsible Gambling
Bankroll management is a tool for controlling risk, not a guarantee of profit. All forms of sports betting carry financial risk, and all bookmaker margins are set against you over time. Only ever bet with money you can genuinely afford to lose.
