EV Kelly Calculator
Institutional-grade position sizing for retail traders.
Stop blowing up trading accounts. EV Kelly is a free, mathematically rigorous position sizing calculator that uses Expected Value and the Kelly Criterion to optimize capital allocation, track trade edge, and prevent risk of ruin.
Hey👋 I'm Rahul, the builder behind EV Kelly Calculator.
I built this tool to solve a brutal reality in the markets: most retail traders do not fail because of bad strategies; they fail because of mathematical ignorance and poor risk management. They over-leverage, ignore statistical variance, and inevitably blow up their accounts.
EV Kelly is a free, institutional-grade position sizing tool designed to replace emotion with mathematics.
You plug in your win rate, reward-to-risk ratio, and total capital. The engine instantly calculates your exact Expected Value (EV) and provides your optimal Kelly fractional sizing (Full, Half, Quarter) to protect against risk of ruin. It also visualizes your geometric growth expectancy over 100 simulated executions.
I built this to force retail traders to treat risk like a quantitative fund would. Test your trading edge, try out the interface, and let me know what you think of the math and the UI. I will be in the comments all day answering questions!
