Multi Lay Calculator

Calculate separate lay stakes for a bookmaker bet that wins through several mutually exclusive outcomes, such as a bet builder covered by different correct scores. Enter the back bet and each outcome’s lay odds and commission to compare stakes, liabilities and combined results. For accumulator legs settled in order, use Sequential Lay.

How to use the Multi Lay Calculator

  1. Choose Bet type and enter the bookmaker Stake and Odds. Use Cashback only for an applicable refund offer.
  2. Choose a Bet builder preset when it matches your bet, or use Add outcome to enter the mutually exclusive outcomes yourself.
  3. Enter Odds and Commission (%) for every lay outcome. Check that the rows cover every way the bookmaker bet can win.
  4. Review each lay stake, liability and the Results table, including the back-bet-loses outcome. Use the native save action if you want to keep the calculation.

Modes and outcomes

Qualifying uses a cash stake. SNR excludes the free-bet stake from winnings. Risk free includes the entered Cashback if the back bet loses. This calculator does not offer an SR mode.

The outcome model assumes that no two listed winning outcomes happen together, and that they cover every way the bookmaker bet can win. Overlapping or missing outcomes invalidate that comparison. A series of accumulator selections is a different calculation.

For example, Team A to win and under 2.5 goals can be covered by 1-0 and 2-0. Laying both component conditions separately would be wrong: both could win together. The calculator’s Total liability is the maximum modelled effective exposure after other winning lays offset the losing lay, not the sum of every row’s standalone liability.

Worked example

Two-outcome cash bet

Back £10 at 2.00. Suppose the bet wins only on outcome A or outcome B, which cannot both occur. Enter lay odds 4.00 and zero commission for each; select Qualifying with standard stakes.

Lay £5 on A and £5 on B. Each individual liability is £15. The combined result is £0 if A occurs, B occurs or neither occurs.

These are illustrative inputs, not current market prices or typical returns. The result assumes matched bets and the stated settlement terms.

Adjustments and changing odds

Custom Stakes scales the lay stakes together to underlay or overlay the bookmaker bet. Review the changed best and worst outcomes. Individual liabilities can add up to more than the maximum modelled combined exposure, but the exchange determines the funds it requires; do not assume offsetting across separate markets or accounts.

Frequently asked questions

Can I use Multi Lay for an accumulator?

Use Sequential Lay for legs settled one after another. Multi Lay covers mutually exclusive outcomes of one bookmaker bet.

What does mutually exclusive mean?

At most one listed outcome can happen. Two different correct scores in the same match are mutually exclusive; two overlapping conditions may not be.

What if I omit a winning outcome?

The bookmaker bet could win without the corresponding lay losing as modelled. The displayed comparison would not cover the real bet.

Can I select SR?

No. The available modes are Qualifying, SNR and Risk free.

Are the displayed liabilities the exact balance my exchange will require?

Not necessarily. Market netting and account rules determine available-balance requirements. Check the exchange bet slip.
