Tricast (Trifecta) Calculator

This tricast calculator works out the return on picking the first three finishers in exact order — the bet US bettors know as the trifecta — from three runners’ American odds, in dollars.

What Is a Tricast?

A tricast asks you to name the first three finishers of a race in exact order — the same bet American bettors call a trifecta. It takes the forecast (exacta) one step further: instead of picking only the winner and the runner-up, you also name the third-place finisher, and all three have to land exactly as called for the bet to cash. Because pinning down three finishing positions in the correct order is genuinely hard, a tricast pays a large price compared with a single win bet or even a forecast.

There are two ways to play a tricast. A straight tricast backs one specific order — Runner A first, Runner B second, Runner C third, for example — and is a single bet at the combined price of the three runners. A combination tricast instead covers every ordering of the same three runners, so however they fill the top three spots, you cash. Three runners can be arranged across three positions in six different orders, so a combination tricast is really six bets rolled into one ticket, costing six times as much as the straight version.

The tricast calculator lets you compare both approaches before staking anything: enter the three runners’ odds, choose straight or combination, enter your stake in dollars, and read off the combined price alongside the payout for each bet type.

How Tricast Payouts Are Calculated

The combined price behind a tricast comes from multiplying the three runners’ odds together, so the first step is turning each runner’s American odds into a decimal figure. For a plus-money price, decimal odds equal the American odds divided by 100, plus one — a runner at +200 becomes 3.00, a runner at +400 becomes 5.00, and a runner at +600 becomes 7.00. Multiply those three decimal figures together and you get the combined price for that exact finishing order.

From there, the two bet types work differently. A straight tricast is a single bet at the combined price: multiply your stake by the combined odds, and that is your payout if the three runners finish in the exact order picked. A combination tricast is six bets — one for every possible ordering of the same three runners — so the total cost is six times the unit stake. Whichever of the six orders comes in, the bet pays the same combined price on that winning line, because every order was covered by an equal-sized bet within the ticket.

A straight tricast is far cheaper for the same three runners, since it pays for one line instead of six. The trade-off is that it needs the exact 1-2-3 to land, while a combination cashes on any order the three runners produce, at six times the outlay. The combined price itself does not change between the two — only the cost and the winning conditions do.

What the Calculator Shows You

Once you enter the three runners’ odds, your stake, and whether you want a straight or combination tricast, the calculator returns a handful of figures. The combined price is the three runners’ odds multiplied together, and it is the number both bet types are priced from. The straight payout shows what a single bet at that combined price returns if the exact order lands. The combination cost shows the total outlay for covering all six possible orderings at the same unit stake, and the combination payout shows what that ticket returns on whichever order comes in. Together, these figures show the cost and reward of backing one precise order against covering every order the same three runners could finish in.

Worked Example

Take a $2 straight tricast on three runners priced +200, +400 and +600. Runner A is backed to finish first at +200, which is 3.00 in decimal odds. Runner B is backed to finish second at +400, which is 5.00 in decimal odds. Runner C is backed to finish third at +600, which is 7.00 in decimal odds. Multiplying the three decimal prices together — 3.00 x 5.00 x 7.00 — gives a combined price of 105.00.

On a $2 straight tricast, that combined price returns $210.00 if the three runners finish A-B-C in exactly that order. Since $2 of that $210.00 is your own stake back, the profit on the winning bet is $208.00.

Now compare that with a combination tricast on the same three runners. Covering all six possible orderings costs six times the $2 unit stake, for a total outlay of $12. Whichever order actually lands — even C-A-B or B-C-A rather than A-B-C — the combination ticket still returns the same $210.00, since every order was covered by an equal $2 line within the ticket. Against the $12 total cost, that produces a profit of $198.00.

The comparison shows the trade-off plainly: the straight tricast returns more profit ($208.00 versus $198.00) because it costs a sixth as much to place, but it only cashes if A, B and C finish in that exact 1-2-3 order. The combination tricast costs more up front but cashes on any of the six possible finishing orders for the same three runners, trading some profit for a wider chance of collecting.

Tricast Return on a $2 Stake by the Three Prices

The table below runs the same $2-stake math across three sets of runner prices, showing how the combined price and straight payout grow as the odds get longer, while the combination cost stays fixed at $12, always six times the $2 unit stake.

Straight vs Combination Tricast

The table below sets the two bet types side by side on a $2 unit stake. A straight tricast is a single bet that only wins on one exact order, while a combination tricast is six bets covering every order the same three runners could finish in, at six times the cost.

Why the Real Trifecta Dividend May Differ From the Combined Price

Like the forecast, the multiplied price this calculator produces is a tote-style model, not a guarantee of what a track will pay. A real trifecta pays a parimutuel dividend drawn from the pool of money bet by everyone, so the actual return depends on how that pool is distributed across all possible finishing orders — it can swing well away from simply multiplying the three runners’ win prices together. Big-field trifectas with longshots have produced dividends of thousands to one, far beyond what multiplying three individual win prices would suggest.

The straight-versus-combination choice is the real decision bettors face. A straight tricast is six times cheaper but needs the exact 1-2-3 to land, while a combination cashes on any order of the three selections at six times the stake. Some bettors look for a middle ground: banking a strong runner to finish first and combining the other two behind it, cheaper than a full combination across three genuinely open positions.

Non-runners are another wrinkle. If one of the selections is withdrawn before the race, it voids the affected bet — the calculator’s combined price assumes all three runners take part, and a scratched runner changes what’s left of the ticket. Dead heats matter too: if two runners cross the line together for a backed position, the dividend on that line is split rather than paid in full, another reason the combined price is a guide to the shape of the payout rather than a promise of the exact number a track will settle.

When Tricast Makes Sense

A tricast suits situations with a genuine read on how a race’s top three will shake out, not just who might win. Because the bet demands three finishing positions in order, it rewards detailed knowledge of a field — pace, running styles, track bias, and how the runners are likely to interact through the race — rather than a simple view on the winner alone. When a small group of runners can be ranked with real confidence, a straight tricast offers a large payout for a modest stake, since correctly ordering three finishers is hard enough that the market prices it generously.

A tricast makes less sense when confidence only extends to which runners will fill the placings, not the order they’ll fill them in. In that case a combination tricast removes the order risk, but at six times the cost, and it is worth weighing whether that outlay is better spent elsewhere, such as a forecast when only the first two positions look clear. Bankroll size matters too: because tricast payouts are large and infrequent, it is easy to overcommit chasing a big price. Treating tricast stakes as a small, separate part of a betting bankroll keeps an occasional big win from masking a run of losing tickets. When the order is uncertain but the contenders are not, a combination or a banker-led combination is usually the more sustainable approach than repeatedly backing one straight order.

Common Mistakes

Backing a straight tricast when genuinely unsure of the finishing order is a common error, since a combination covers all six possible orders instead of just one. Bettors also sometimes expect the calculator’s multiplied price to match what a track’s parimutuel pool actually pays out, when the real dividend depends on the money bet by everyone else. Paying six times over for a combination when the order is actually fairly clear wastes stake a straight tricast would have covered more cheaply. Finally, it’s easy to overlook how a non-runner voids part or all of the bet, changing what a ticket is still eligible to pay.

Tricast vs Forecast

A tricast extends the forecast (exacta) from two finishing positions to three, which is why it needs six bets rather than two to cover every order, and pays a much larger price for the same kind of precision.
