What a Perm Bet Is
A perm, short for “permutation,” is the jackpot of multi‑horse wagering – you pick a set of horses and the system automatically assembles every possible combination for you. If you choose five horses in a 5‑fold perm, you’re actually placing five single bets, ten doubles, ten trebles, five four‑folds, and one five‑fold. Simple concept, monstrous payoff if the odds line up.
Breaking Down the Numbers
Look: each combination has its own price tag, the stake you lay on it. Multiply the stake by the number of combos, and you’ve got the total cost. The math can explode quickly – a six‑horse perm at a £1 stake becomes 63 separate bets. That’s £63, not £6. Beginners often miss that hidden multiplication factor.
Step‑by‑Step Cost Formula
Here’s the deal: first, decide how many horses you want to include – let’s call that N. Next, decide the smallest bet size you’re comfortable with – call that S. The total combos C is the sum of “N choose k” for each k you want to cover (usually k = 2 up to N). Finally, total cost = C × S.
Example time. You pick 4 horses, stake £2 each, and you want every possible combo from doubles up to a four‑fold. C = C(4,2)+C(4,3)+C(4,4) = 6+4+1 = 11. Multiply 11 by £2, you pay £22. That’s the exact amount you’ll see on the betting slip, no surprises.
Common Pitfalls
And here is why many punters get burned: they treat the perm as a single bet and think they’re only risking their stake, not the multiplied total. Also, forget about taxes or commission on each win – those fees are applied per individual bet, not on the perm as a whole. A smart bettor runs the numbers before the race, not after the horse has galloped off the track.
Another trap: ignoring the “overround.” Bookmakers bake a margin into each market, so the sum of implied probabilities is over 100%. Stack too many combos and the overround drains your profit even when you’re technically “right.”
Quick Tips for the Savvy Bettor
Use a reliable calculator. One click on betcalculatorfast.com and you’ll see the exact outlay, the potential return, and the break‑even point. Don’t gamble blind – the tool shows you the profit after commission, so you can decide if the risk matches the reward.
Keep the stake low when you’re testing a new perm size. A £1 stake on a ten‑horse perm hits £1,023. That’s a lot of money to lose on a single race if the odds don’t line up.
Finally, remember to factor in your bankroll. If your total cost exceeds 5% of your gambling fund, you’re probably over‑committing. Cut the perm down, or lower the stake, and stay in the game.
