What Is a Sports Betting Bankroll?
A sports betting bankroll is the pool of capital you have specifically allocated to wagering. That sounds simple. In practice, the word "specifically" is doing most of the work.
Your bankroll is not your checking account. It is not your emergency fund. It is not next month's mortgage payment. And it is not whatever money happens to be sitting in your sportsbook account today.
A professional betting bankroll is dedicated risk capital.
If losing a portion of that money would interfere with your ability to pay ordinary living expenses or meet financial obligations, that money should not be part of the betting bankroll.
Think of the bankroll as working capital
For a professional bettor, the bankroll has a job. It allows us to repeatedly put money into action when we believe we have a favorable wagering opportunity.
Some wagers will win. Some will lose. Sometimes the losses will arrive in clusters. The bankroll must be large enough to absorb those fluctuations while allowing us to continue operating normally.
That's why we prefer to think of a bankroll as working capital rather than gambling money. The objective isn't merely to have enough money to place today's wager. The objective is to have enough capital to place tomorrow's wager after today's wager loses. And the wager after that. And the wager after that.
Your bankroll determines your unit—not the other way around
This is where many bettors get themselves into trouble. They begin by deciding how much they want to bet. “I want to bet $500 per game.” Then they attempt to determine how much bankroll they need to justify that wager. We prefer to reverse the process.
First establish the bankroll. Then establish a dollar amount for the bet size based on a percentage of the established bankroll (we discuss that percentage below). That standard wager becomes your unit.
A unit gives wager size context
Without knowing the bankroll supporting it, the number tells us very little. Units solve that problem. If someone tells us he lost $10,000, we don't know much. If he tells us he lost 10 units, we immediately know considerably more about the magnitude of the loss relative to his normal wagering activity.
This is why professional bettors frequently discuss performance in units rather than dollars. The unit creates a common measuring stick.
About sportsbook balances and bankroll
First, you do not need more than five betting units in any one sports book at a time. Once your sports book account climbs to eight or nine units, you should order a cashout. You have nothing to gain from storing money in a sports book. Sportsbooks are not banks with guarantees that your funds will be returned if they go bankrupt. Prediction markets are safer and better to leave larger sums of money, assuming they pay interest on your balance.
Professional bettors should have money distributed among several sportsbooks, prediction markets and betting exchanges. Those individual account balances are part of the same bankroll. Also, all of your bankroll funds might not even be deposited in sports books.
You may keep most of your bankroll in the bank. Your bankroll does not necessarily have to be in liquid funds, as long as you can convert it quickly if needed.
The bankroll is the total capital allocated to the betting operation. Where that capital happens to be parked is an operational question. This matters because wager sizing should be based on a coherent view of the entire betting capital.
