Every serious punter does a little maths before the off. What does this Lucky 15 actually return if three of the four win? Is 11/4 a bigger price than 3.5 on the exchange? If I take 8/1 each-way at a quarter the odds, what comes back if my horse only places? You can do all of it on the back of the Racing Post with a biro — or you can let these tools do it in a second, correctly, every time.
This is the horse.bet workshop for UK and Irish racing. Every tool here is free, needs no account, and runs in your browser. None of them try to pick winners for you — that’s the predictor’s job. These are the everyday instruments: the calculator that settles your bet slip before you place it, the converter that lets you compare a high-street price against an exchange price, and the focused tools for the two bets British punters reach for most — the Lucky 15 and the each-way.
Each tool below has its own page with worked examples and an explainer. Start with whichever matches the bet in front of you.
The all-rounder. Work out the return on any bet a UK punter places: singles and accumulators, the full-cover bets (Trixie, Patent, Yankee, Lucky 15/31/63, Canadian, Heinz, Super Heinz, Goliath), each-way, and Rule 4 deductions when a fancied horse is withdrawn. Enter your prices, mark each result, and it totals your stake, returns and profit — and tells you how many bets make up the wager.
The British Saturday staple. Four selections, fifteen bets, and one winner is enough to get something back. This focused tool handles the standard bookmaker bonuses — double the odds for one winner, a 10% boost when all four land — and works each-way too.
Two bets in one: half your stake on the win, half on the place. This tool splits the win part and place part so you can see exactly what comes back whether your horse wins or just places, at any place terms from 1/5 to 1/2. Essential for big-field handicaps and festival extra-place markets.
Fractional, decimal, American and implied probability, all linked. Type a price in any format and the rest update instantly — handy for comparing a bookmaker’s 11/4 against an exchange’s 3.75, or seeing the true percentage chance a price implies.
The model. Pick any UK or Irish race and the predictor strips the bookmaker margin, weighs the form, ratings and stable data, and surfaces the horses priced longer than their true chance. Where the calculators do arithmetic, the predictor offers a worldview.
Trainer and jockey form, course records and daily results are on our UK racing-data pages.
A typical Saturday runs like this. Open the predictor on the races you fancy and note the value picks. Use the odds converter if you’re shopping a price across bookmakers and an exchange and want them in the same format. Settle on a bet — a straight win, an each-way play in a big handicap, or a Lucky 15 across the ITV cards — and run it through the bet calculator (or the focused each-way / Lucky 15 tools) to see what it returns before you commit. Five minutes, and you’ve gone from a hunch to a priced, sized bet.
Yes — all of them, with no account or sign-up. They run in your browser and don’t store anything.
Yes. The bet calculator and each-way calculator both split the win and place parts, and the bet calculator applies Rule 4 deductions for UK bets when a fancied runner is withdrawn.
Either the full bet calculator (choose “Lucky 15” from the bet-type menu) or the focused Lucky 15 calculator, which has the standard bonuses built in.
The calculators use the prices you enter, so they’re only as current as your figures — always confirm the live price and your returns on the bookmaker’s bet slip before placing.
Responsible gambling line: For guidance only — always confirm returns with your bookmaker before betting. 18+. GambleAware.org.
