Each-Way Double Calculator

The Each-Way Double Calculator calculates potential returns and place payouts for each-way double bets, including stake distribution and odds.

What Is a Each-Way Double Calculator?

An Each-Way Double Calculator works out the payout for an each-way double bet. An each-way double is two linked doubles: one on the win parts of both selections and one on the place parts. You stake twice—once on the win double and once on the place double.

To make it simple, think of two lines. The win line only pays if both selections win. The place line pays if both selections place, and a winner counts as a place. The calculator separates these lines, applies place terms, and combines them into a total return and profit.

The Mechanics Behind Each-Way Double

Each-way betting splits your stake into a win part and a place part. When you build a double, those parts multiply across two selections. The sportsbook’s each-way terms reduce the place odds, based on race type and field size.

• You place a stake on the win double and the same stake on the place double.
• The win double pays only if Selection 1 and Selection 2 both win.
• The place double pays if both selections finish in paid places; a winner also qualifies as placed.
• Place odds are the original odds reduced by the advertised place fraction (for example, 1/5 or 1/4).
• If a leg is void or a non-runner, that part of the double becomes a single on the remaining leg.

This structure means you can still receive a payout when one selection only places. But the biggest returns occur when both selections win, because both the win line and the place line pay.

Each-Way Double Formulas & Derivations

The calculator uses standard bookmaker settlement logic. It converts odds, applies place fractions, and multiplies returns across both legs. Here are the core relationships it uses, shown for fractional or decimal inputs.

• Convert fractional to decimal: If fractional odds are a/b, decimal D = 1 + a/b. Example: 7/2 → D = 1 + 3.5 = 4.5.
• Place terms: If the place fraction is t (such as 1/5), place decimal Dp = 1 + t × (a/b) = 1 + t × (D − 1).
• Win line return: Rw = S × D1 × D2, only if both legs win; otherwise Rw = 0.
• Place line return: Rp = S × Dp1 × Dp2, only if both legs place (wins count as place); otherwise Rp = 0.
• Total return and profit: Rtotal = Rw + Rp; Stake total = 2S; Profit = Rtotal − 2S.
• Voids: If a leg is void, set its decimal to 1.0 on that line, which reduces the double to a single for settlement.

These formulas match common sportsbook practices. Some firms apply rounding on each leg or line, typically to the nearest penny. The calculator rounds the final return to two decimals unless your bookie states otherwise.

What You Need to Use the Each-Way Double Calculator

Gather a few details, then plug them in. The calculator accepts decimal or fractional odds and adapts to common settlement rules in racing sportsbooks.

• Stake per line (S), for example £5 or $10 (total stake is 2S for each-way).
• Selection 1 odds (fractional like 7/2, or decimal like 4.5).
• Selection 2 odds (fractional or decimal).
• Place terms for each selection (for example, 1/5, 1/4, or 1/3).
• Result of each selection: Win, Place, Lose, or Void/Non-Runner.
• Optional adjustments: Rule 4 deduction and dead-heat details, if they apply.

Odds must be positive, stakes must be non-negative, and place terms must be in realistic fractions. If a leg loses, its line returns are zero for that leg’s requirement. If a leg is void, its decimal becomes 1.0 on the affected line(s) and the double reduces accordingly.

Step-by-Step: Use the Each-Way Double Calculator

Here’s a concise overview before we dive into the key points:

1. Enter your stake per line S; remember your total stake is 2S for an each-way double.
2. Enter odds for Selection 1 and Selection 2 in either fractional or decimal format.
3. Choose place terms (for example, 1/5 or 1/4) for each selection.
4. Select the outcome for each leg: Win, Place, Lose, or Void/Non-Runner.
5. If relevant, add any Rule 4 deduction or dead-heat details for an affected leg.
6. Press Calculate to see the win line, place line, total return, and profit.

Worked Examples

Example 1: You stake £5 each way on a horse racing double. Selection 1 is 3/1 at 1/5 place terms and wins. Selection 2 is 10/1 at 1/5 place terms and places. Win double requires both to win, so the win line returns £0. Place decimals: Dp1 = 1 + (3 × 1/5) = 1.6, Dp2 = 1 + (10 × 1/5) = 3.0. Place line return = £5 × 1.6 × 3.0 = £24. Total stake = £10. Total return = £24. Profit = £14. What this means: Your winner still helps land the place double, cushioning the loss of the win line.

Example 2: £5 each way on a double. Selection 1 is 7/2 at 1/5 place terms and wins. Selection 2 is 9/1 at 1/4 place terms and wins. Win double decimals: D1 = 4.5 and D2 = 10. Win line return = £5 × 4.5 × 10 = £225. Place decimals: Dp1 = 1 + (3.5 × 1/5) = 1.7, Dp2 = 1 + (9 × 1/4) = 3.25. Place line return = £5 × 1.7 × 3.25 = £27.63 (rounded). Total return = £225 + £27.63 = £252.63. Total stake = £10. Profit = £242.63. What this means: When both win, both lines pay, producing a much larger payout.

Accuracy & Limitations

The calculator mirrors common settlement rules used in racing sportsbooks. Still, a few shop-specific policies can change outcomes slightly, especially around deductions and rounding.

• Place terms vary by race type and field size; always use the exact fraction shown by your bookie.
• Rule 4 deductions reduce winnings, not the stake; rates depend on withdrawn horses and timing.
• Dead-heat handling often splits stakes on the affected line; some firms round differently.
• Void or non-runner legs convert the double into a single for the remaining leg on each line.
• Some promotions (for example, Best Odds Guaranteed) may change final settlement versus the early price.

If your sportsbook publishes different rules, use its policy first. You can still replicate most variations by adjusting place terms, toggling voids, and applying suitable Rule 4 or dead-heat inputs.

Units and Symbols

Odds and returns do not use traditional physical units, but consistency matters. Use one currency for stakes and returns, and choose a single odds format. If a bookmaker quotes SP rather than a fixed price, note that place terms and deductions can still apply.

Read the table as a quick reference while entering data. For example, convert F to D, then apply t to get Dp. Use the same currency for S and for the final return so your ROI is clear.

Tips If Results Look Off

Mismatches usually trace back to place terms, voids, or mixed odds formats. Check these first before you re-run the numbers.

• Confirm that both selections use the correct place fraction for their race.
• Be sure you did not mix fractional and decimal odds by mistake.
• Verify outcomes: a win counts as a place on the place line.
• Account for any non-runners, dead heats, or Rule 4 deductions.
• Check whether your bookie rounded per line or only at the final return.

If you still see a gap versus a bookmaker’s settlement, read their rules page for that market. Then mirror any special terms using the optional adjustments.

FAQ about Each-Way Double Calculator

Is an each-way double two bets or four?

It is two bets: one win double and one place double, each staked equally. Your total stake is twice your per-line stake.

Does a winner count as placed on the place line?

Yes. A win qualifies as a place for settlement. This allows a place double to land even when only one selection wins and the other places.

What happens if one selection is a non-runner?

The double becomes a single on the remaining selection for both the win and place lines. The void leg’s decimal is treated as 1.0.

How do Rule 4 deductions affect my return?

Rule 4 deducts a percentage from winnings (not stake) when a runner withdraws. The calculator applies this to the winnings portion of each affected line.

Key Terms in Each-Way Double

Each-Way (E/W)

A bet split into win and place parts. With a double, those parts combine across two selections, creating a win double and a place double.

Double

A multi-leg bet where both selections must meet the requirement for a payout. Win doubles need both to win; place doubles need both to place.

Place Terms

The fraction used to reduce win odds to place odds, such as 1/5 or 1/4. It depends on race type and field size set by the sportsbook.

Rule 4

A deduction from winnings after a runner is withdrawn. It is expressed as pence in the pound or a proportion applied to the winnings element.

Dead Heat

A tie between runners for a win or place. Settlement typically splits the stake across the number of tied runners on the affected line.

Non-Runner (Void)

A selection that does not start. In doubles, the affected leg becomes void, turning the remaining leg into a single on each line.

Starting Price (SP)

The official price at the start of a race. Bookmakers may settle at SP or an early price, which can change returns and deductions.

Accumulator

A bet with three or more selections where all legs must meet the requirement. It follows similar logic to a double but across more legs.
