Sports Betting Money Management


A successful sports betting strategy begins with managing your bankroll.


To make a profit long term betting sports you must treat it as you would any other business. The old saying is that you should not use your rent money to bet with. This is true; however, if you're betting sports for profit it is equally true that you must not use your gambling bankroll to pay the rent.

When it comes to sports betting, each person may be trying to accomplish something different. If your objective is merely entertainment, then your goal is entirely different than my goal of making a profit. If you bet $100 a game on Monday night football to enjoy the game, it will cost you $5 a week if you can go 50-50. There is nothing wrong with this. It's cheaper than a movie. But this is entertainment expensenot an excellent investment vehicle.

In sports betting, your inventory is your cash. If you run out of cash, you are out of business.

The amazing thing about sports betting is the return on investment (ROI) that is possible. There is no magic. The return on investment is a function of the winning percentage and the amount that is invested. The amount invested is a function of the number of bets (investments) and how much you lay on each bet. It is the same as any business. How many widgets did you sell and how much did you gross per widget?

We average around 1,500 plays per year. Most professional-level sports bettors wager around one to two percent of their beginning bankroll per bet. This is called a unit. The maximum unit (bet size) should not exceed two percent of your bankroll. If my pain tolerance is two percent, I would bet 2% of my bankroll on every bet. That means I will bet two percent of my money 1,500 times...3,000% of my bankroll. I will bet the same money thirty times in one year. 

If I win 55% of my 1500 plays, I win 825 units and lose 675. The bookmaker returns your 825 units wagered on the winners plus your winning which are 751 units after you pay the vigorish – or a “broker” fee to the sportsbook - of 74 units (see our free article A Crash Course in Vigorish). Therefore, I win 76 units profit. (76 units @ 2% of my bankroll is 152% of my bankroll. I more than double my money.)

Some people think they can make a living betting $100 a game. Well, think about it. If they play 25 games a week, they will lay $2,500. If they are good, they will win 14 games and lose 11. For the losing bets, they forfeit $1,100. For the winning bets, the bookmaker returns their original $1,400 plus $1,274 in winnings. This amounts to $174 profit – clearly not enough to live from. Depending on your lifestyle, typically a minimum unit of $300 to $400 is required to make a living betting sports; although, this leaves little to grow the business. Remember you need a $20,000 bankroll to play a $400 unit.

As soon as you can draw from the business, you should put yourself on a salary. That way you can know what to expect for an income and won't be bothered by the short-term vagaries of Lady Luck.

After over thirty years, we know the number of plays we have each year. We know our bet size. With 1,500 plays, the standard deviation for our win percentage is 2. We know we win between 53% and 57%. Sounds rather dull when we put it that way. And I guess it is. Bernard Baruch, the great financier, said he always looked for boring businesses. They were well run, without surprises and he knew what to expect.

I know what to expect. One great lesson we point out is that with a 55% expectation, your bankroll would reach a new high only 5% of the time. Nineteen out of 20 days you will be below your bankroll high. The novice thinks you should have more money each day. I also know that with a 55%-win rate and 125 bets a month, I will lose money every 9th month. Good money management is aided by knowing what to expect.

As a final note on bet size, I should add that I use a plateau system.

I bet 2% of my bank and continue to flat bet until my bank grows by at least 25%. Then I recalculate the 2%. Thus, if I started with $10,000, I would bet $200 a game until my bank grows to at least $12,500. At that point, I would refigure my unit to $250. I bet flat until I reach at least $15,625. My actual risk-reward ratio doesn't get too high. The other thing that I do that is unique and rather arguable is that I never lower my bet. Remember, if you vary the bet, your breakeven goes up. At a 2% unit and three decades of experience, I am comfortable that I can ride through a losing streak. If you lose 10 games at $200 a bet and lower the bet to $180, you must win 12.2 bets to get back to even. This is how I get my 100% annual ROI. My actual bet goes up during the year as my bankroll reaches higher plateaus.




In a nutshell:

With sports betting you don't wait for weeks or months to know if your investment was successful. You get an answer in about three hours…you have no time clock, no boss, no employees, no “customers',” no daily commute battling traffic - none of the hassles of most everyone else you know.
