Odds converter
Compare decimal, fractional and American prices, measure a market’s overround and explore a probability assumption.
- Three odds formats
- Market overround
- Probability scenarios
Choose the calculation that matches your receipt. Each workspace has adjustable terms, detailed metrics, scenario comparisons and a guide to the arithmetic.
Each calculator uses the terms you enter rather than a bookmaker's rules. Before settling a football market, confirm which period the score refers to in how to read football scores; for racing, result statuses explains when a placing is provisional. Finished results are in the football archive and the racing archive.
Compare decimal, fractional and American prices, measure a market’s overround and explore a probability assumption.
Model cash and stake-not-returned free bets, deductions, dead heats and commission with a complete cash-flow breakdown.
Set unequal win/place stakes, custom place fractions, separate deductions and dead-heat shares, then compare finishing positions.
Build up to 12 named selections with mixed odds formats, individual outcomes, half settlements and voids.
Combine doubles through twelve-folds, select common systems, choose stake per line or total budget and export every combination.
Check nine market types, quarter-goal splits, score stages and a configurable scoreline sensitivity matrix.

A sporting result alone does not establish how a market settles. The receipt determines the period, price, stake basis and applicable rules. Enter those terms, then compare the displayed cash outlay, return and net result with your statement.
Each tool distinguishes known inputs from hypothetical scenarios. Starting values are examples, not suggested bets. No tool places a wager, predicts a winner or infers an operator’s withdrawal, promotion or voiding policy.
Save named setups on this device to compare receipts without re-entering every field. Export a setup as JSON to move it to another browser, or download the calculated breakdown as CSV. Saved setups stay in browser storage until you delete them or clear site data; they are not sent to results.fast.
Currency changes the display label only. It does not convert exchange rates. Display precision can be changed independently of the internal arithmetic. For exact reconciliation, check whether your operator rounds each component before adding the total.
