Most bettors don't go broke because of bad picks. They go broke because of bad money management. You can hit 55% of your bets and still lose everything if you bet too much on the wrong nights and too little on the right ones. The fix is a system, and ours is simple enough to follow forever.
Bet in Units, Not Dollars
A unit is a fixed percentage of your bankroll, not a dollar amount. We rate every play on a 1-to-10 scale: a 1-unit play is a lean, a 7-to-10 unit play is a strong opinion. Because a unit is a slice of your bankroll, your bet size scales automatically as your bankroll grows or shrinks. You never have to "feel" your way into a bet size again.
Why Scaling Protects You
When your bankroll dips, your units shrink with it, so a cold streak can't wipe you out. When it grows, your units grow, so you press your edge without ever risking ruin. That single mechanic, sizing proportionally, is what separates bettors who last decades from bettors who blow up in a month.
Put It Into Practice
Decide your bankroll, set one unit at 1-2% of it, and never deviate. Use our Kelly Criterion calculator to sanity-check sizing on bigger plays, and follow the full method in the Masterclass bankroll lessons.
Frequently asked questions
What is a unit in sports betting?
A unit is a fixed percentage of your bankroll, typically 1-2%, rather than a dollar amount. Betting in units means your stake scales automatically with your bankroll.
How does the 1-to-10 unit system work?
Every play is rated 1 to 10 by conviction. A 1-unit play is a lean; a 7-to-10 unit play is a strong opinion. Since a unit is a slice of your bankroll, sizing stays proportional and controlled.
