The Trifecta or Tricast is a wager laid in horse racing meant to pick the first, second, and third in the exact order they’ve finished the race. The Trifecta is one of the most popular exotic wager available in horse racing and so the use of a trifecta calculator, which is a horse racing calculator, is very common among punters.

The Trifecta wager is available in three different variations:

**Straight Trifecta**, the most common type of Trifecta in which the punter must pick 3 horses and the order in which these 3 horses will line up at the finish line. Have on horse misplaced and the wager is lost. For example, a punter fancies horse 2 and thinks 5 can go about finishing second and 7 is possible for finishing third. The punter registers the selection in the following manner, 2, 5, 7 and lays a wager on the selection. Each additional horse is an additional combination costing the original wager.

**Trifecta box**, a wager in which three horses or more are picked and the wager covers all possible combinations of these horses’ lining up at the finish line. The more horses added to the selections, the more combinations become possible and the stakes are raised.

**Trifecta wheel**, a wager in which one horse is picked for the win and two others are picked for two possible outcomes where each of them must finish third or second respectively. Again, the more horses introduced as selections, the more combinations costing money.

Wagering a Trifecta is something that should be practiced by experienced handicappers only, and the use of a horse racing calculator in the form of a Trifecta calculator is highly recommended in order to keep track of the combinations and their price, so that no undesired combination is made and no payouts below the stakes becomes possible. Trifecta payouts can turn out pretty nice but only in cases where no favorites lined up, so laying a Trifecta is recommended only when the punter notices an overpriced horse or when there are no clear favorites. Payouts increase significantly when the race has 8 runners or more and decrease significantly when the number of runners is below 8 down to 6.

**Trifecta Calculator
**The Trifecta calculator is a type of a horse betting calculator. In order to calculate the costs of laying a Trifecta wager, a punter must use the Trifecta calculator, either manually or by a computerized Trifecta calculator. The calculations are rather simple. Assume a punter lays a £2 wager on a Trifecta wheel, picking horse number 7 as first and horses number 6 and 5 for the second and third. When adding combinations, regardless of the Trifecta type, the original price is multiplied by the number of combinations chosen by the punter. The payout calculation is the ratio between the Trifecta pool and the amount of money placed on the winning combination, so if there is £100000 in the Trifecta pool and £2000 wager on the winning combination, the £1 payoff will be £50.
