Tools & Calculators

Free reference utilities for anyone who places a bet. Built to load instantly on a phone, run without a login, and skip the popups. Each one is a single page that does one job well.

Odds Converter

Every betting odds format on one screen. Type a value in decimal, American, fractional, implied probability, Hong Kong, Indonesian, or Malay and the other six fill in as you go.

Parlay Calculator

Combined odds, total payout, net profit, and implied hit-rate for an accumulator of any number of legs. Mix odds formats per leg if your books quote differently.

Casino Bonus EV

Find out whether a welcome bonus is worth taking once wagering, game contribution, and house edge are baked in. Shows net expected value and the break-even house edge.

More calculators on the way. If you'd find a specific one useful (Kelly sizing, free-play expected value, no-vig pricing), post a request in the sports talk forum.
