The Mathematics
Convert each horse's fractional price to decimal by dividing the numerator by the denominator and adding one. A winning Lucky 63 component returns its unit stake multiplied by all decimal prices in that component. A losing component returns zero. The combination count C(n,k) means choosing k horses from n without regard to order. For this ticket n is 6, and k runs from 1 to 6; adding those counts gives 63. A horse participates in several components, so changing its result can remove many payouts, not just one.
Component counts: 6 singles, 15 doubles, 20 trebles, 15 fourfolds, 6 fivefolds, 1 sixfolds
Total stake = 63 × unit stake
Component return = unit stake × product of decimal odds, if every member wins
Total return = sum of winning component returns
Profit = total return − total stake
Worked Example
Worked Lucky 63 example: enter £1 as the unit stake and 2/1 for all 6 horses, giving decimal 3.00 for each. With All Win selected, total stake is £63. The breakdown is 6 singles × £3 = £18; 15 doubles × £9 = £135; 20 trebles × £27 = £540; 15 fourfolds × £81 = £1215; 6 fivefolds × £243 = £1458; 1 sixfolds × £729 = £729. Total return is £4095; overall profit is £4032. If exactly two of these horses win instead, return falls to £15 and the overall result is £-48.00. If none win, return is £0 and the full £63 stake is lost. These are ordinary cash-stake returns with no bonus.
How do I enter a Lucky 63 correctly?
Enter one quoted price for each of the 6 selection rows, then enter the amount staked on each individual line in Unit Stake. For example, a 20p unit costs £12.60 overall; entering £20 does not mean a £20 ticket, it means £1260.00 invested across 63 components. The widget accepts fractional prices such as 5/2, and its shared odds parser also accepts decimal numbers. Keep all rows filled even when a horse loses, because the ticket calculation still needs the complete original selection list.
Each row starts on Won, so the first complete result is the all-winners scenario. Click a row's Won button to mark that selection Lost, or use None Win and then switch on only the successful horses. Check the winner count, total stake, and the group-by-group breakdown together. A displayed return includes returned stakes only on successful lines; it does not refund the stakes of losing lines. Compare the final profit with the whole outlay rather than comparing a successful double with its own unit stake.
What makes a Lucky 63 different from nearby bets?
The Lucky 63 is the six-selection full cover with singles. It adds six straight win bets to a Heinz and retains all fifty-seven multiple lines. Its twenty trebles form the largest individual group, while its sixfold is only one line among sixty-three.
A £1 Lucky 63 costs £63, so even a lone 20/1 winner returns only £21 and leaves a £42 loss. One winner needs 62/1 merely to break even without concessions. A 10p unit reduces the bill to £6.30 but does not change the ratio between returns and outlay.
A straight 6-selection accumulator has one stake and requires every selection to win. The Lucky 63 has 63 stakes and retains shorter winning components when other horses lose. That is a trade-off between ticket cost and outcome coverage, not free insurance or proof of better value. To compare fairly, fix a total spending limit first: a £63.00 budget permits £1 per Lucky 63 line or £63.00 on one accumulator. Comparing both at a £1 unit would compare different amounts of money.
How should partial results and settlement changes be read?
Exactly three 2/1 winners generate £63.00 in ordinary Lucky 63 returns at £1 per line, regardless of which losing horses fill the remaining rows. Subtract £63, not the number of successful lines, to obtain the ticket result. With mixed prices, the identities of the winners matter: a double at decimal 2.00 and 3.00 returns £6 per £1, while decimal 4.00 and 5.00 returns £20. A simple winner count cannot therefore determine the payout on its own.
This widget models win-only cash bets with Won or Lost states. It does not settle each way components, void selections, Rule 4, dead heats, free bets, best odds guaranteed or Lucky bonuses. A non-runner is not a loser: under ordinary non-runner rules an affected multiple is reduced, so existing component lines may collapse into smaller bets while retaining their separate stakes. Do not toggle a non-runner to Lost and treat that as bookmaker settlement. Obtain the operator's component breakdown and apply its rules separately.
Popular questions about this calculator
How many bets are in a Lucky 63?
A Lucky 63 has 63 components from 6 selections: 6 singles, 15 doubles, 20 trebles, 15 fourfolds, 6 fivefolds, 1 sixfolds. The count is the number of stakes, not the number of races. At a £1 unit the ordinary win-only outlay is £63, even if some of the chosen horses subsequently lose.
Does a Lucky 63 include singles?
Yes. It includes 6 singles, one on each horse, as well as all larger combinations. This determines whether one winner can return anything, but it does not tell you whether the entire ticket has made a profit.
What does a 50p Lucky 63 cost?
A 50p Lucky 63 costs £31.50 win-only because all 63 lines receive a 50p stake. If a bookmaker accepts the same combination each way at 50p per part, the outlay doubles to £63. The widget on this page calculates only the win-only version.
How much does a Lucky 63 return with two 2/1 winners?
At £1 per component, two 2/1 winners return £15. That is £3 from each single plus £9 from their double. Subtract the original £63 ticket stake to determine the final profit or loss.
Is a Lucky 63 the same as a Heinz?
No. The Lucky 63 is the six-selection full cover with singles. It adds six straight win bets to a Heinz and retains all fifty-seven multiple lines. Its twenty trebles form the largest individual group, while its sixfold is only one line among sixty-three. When comparing the two, use the same total budget and the same accepted prices. The extra coverage changes both the bill and the partial-result payouts; it is not an automatic financial advantage.
Can one winner cover a Lucky 63 stake?
A lone winner must have decimal odds of at least 63 to cover the ordinary 63-unit stake: fractional 62/1 breaks even. A higher price makes a profit. This threshold assumes no enhancement, deduction or dead heat and applies whatever positive unit stake you use.
Can I calculate an each way Lucky 63 here?
No. The component names and count describe a win-only Lucky 63. An each way version has separate win and place combinations and doubles the outlay at the same unit stake. Place fractions can differ between races, and a place-only result is not equivalent to marking the horse Won.
What happens to a Lucky 63 if a horse is a non-runner?
Under ordinary non-runner terms, a void leg drops out of each affected multiple while the component's stake stays in that line. A void single, where present, is refunded. Ante-post conditions can differ. This calculator has no void state, so request a settlement breakdown rather than substituting Lost for a withdrawal.
Does the Lucky 63 calculator include bookmaker bonuses?
No. It calculates base returns at the prices supplied. One-winner enhancements, all-winner bonuses, best odds guaranteed and free-bet stake rules are operator-specific. Read the qualifying conditions and the definition of enhanced winnings before adding an offer, because enhancing profit is not the same as multiplying total return.
Why can a Lucky 63 show a return but negative profit?
A return is money paid by successful components; profit subtracts all 63 original stakes, including losing lines. A £1 Lucky 63 costs £63, so even a lone 20/1 winner returns only £21 and leaves a £42 loss. One winner needs 62/1 merely to break even without concessions. A 10p unit reduces the bill to £6.30 but does not change the ratio between returns and outlay. The profit figure is therefore the more useful comparison with the ticket's original cost. A calculator illustrates arithmetic; it does not establish a profitable selection strategy.
