Matched Betting Calculator
Qualifying bets, free bets (SNR) and stake-returned free bets. Instant lay stake, liability and locked-in profit.
Arbitrage Calculator
Two- and three-way surebets. Splits your stake across bookmakers and shows guaranteed profit and ROI.
Each-Way Calculator
Lay the win and place parts of an each-way qualifying bet or free bet, with the result for win, place and unplaced.
Dutching Calculator
Spread a stake across up to eight selections for the same return whichever wins, with rounding.
Odds Converter
Decimal, fractional and American odds with implied probability and £10 returns.
Service Comparison
Outplayed, OddsMonkey, Profit Maximiser and the free options side by side: price, tools, offers and Trustpilot.
Sizing the bet is one job; keeping a record is the other. The free profit tracker spreadsheet logs what each bet actually made, breaks it down by bookmaker and offer type, and flags an account that has gone quiet.
Working out a betting slip
Multiple and full-cover bets, where the hard part is knowing how many bets you are actually placing. Every one of these handles each-way places, non-runners and the Lucky bonuses, and takes fractional or decimal odds.
Bet Calculator
Every bet type in one tool: singles, doubles, trebles, accas and all the full-cover bets.
Lucky 15 Calculator
Four selections, fifteen bets, with double-odds consolation and the all-winners bonus.
Lucky 31 Calculator
Five selections across thirty-one bets, including the 20% all-winners bonus.
Lucky 63 Calculator
Six selections, sixty-three bets. Worth checking the stake before you place it.
Patent Calculator
Three singles, three doubles and a treble, so one winner still pays something back.
Trixie Calculator
Three doubles and a treble. Cheaper than a Patent, but one winner returns nothing.
Yankee Calculator
Six doubles, four trebles and a four-fold across four selections. No singles.
Round Robin Calculator
Ten bets on three selections, including the six up-and-down pairs.
Accumulator Calculator
Doubles through six-folds, with non-runners settled the way bookmakers settle them.
