Calculators
Six free tools, grounded in each platform's own real, documented fee formula — no account required, nothing stored.
Market Fees
See exactly how much each platform's own documented fee formula charges at a given price.
Vig & No-Vig
Real overround embedded in a two-sided market's own pricing, and the fair (no-vig) probability with it removed.
Expected Value
Whether a trade is +EV given your own real probability estimate versus the current market price — not a claim your estimate is correct.
Odds Converter
Convert between implied probability, American odds, and decimal odds — two independent converters, since the odds format you start from usually differs from the one you're checking it against.
Parlay
Combine several independent legs into a blended probability, payout, and ROI — assumes each leg is independent, which a real correlated parlay (e.g. two props in the same game) won't be.
Net Profit
Real take-home after each platform's own documented fee, and an optional flat tax rate on winnings you supply — this app doesn't know your real tax situation, so nothing is assumed by default.
