TOOL: EV.CALC EV Calculator

Calculate expected value in dollars and percent. Enter American odds and your estimated win probability to see if the bet is +EV or -EV.

TOOL: STAKE.KELLY Kelly Criterion Calculator

Find the optimal bet size for your bankroll. Supports full, half, and quarter Kelly when you want to reduce volatility.

TOOL: ODDS.TRANSLATE Betting Odds Converter

Convert American, decimal, and fractional betting odds instantly. Shows implied probability and breakeven win rate.

TOOL: US.PRICE American Odds Calculator

Convert American odds into implied probability, decimal odds, and break-even win rate before you bet.

TOOL: RISK.CONTROL Bankroll Management Calculator

Estimate unit size, staking limits, and practical bankroll guardrails before variance attacks the account.

Why run the tools? Sportsbooks show a price. They do not show the probability threshold, the hidden margin, or whether your estimate clears the line. These calculators expose the missing layer.

Recommended workflow

1

Translate the odds

Convert the sportsbook price into implied probability and breakeven win rate.

2

Estimate fair probability

Use research, model output, matchup context, injuries, and market comparison to form a probability you can defend.

3

Check EV and stake size

If the edge is positive, run Kelly or a conservative fraction before deciding whether the risk belongs in your bankroll.
