Sequential Lay Calculator

Plan an accumulator hedge one leg at a time. Calculate each lay stake, liability and stopped outcome, then update later prices as earlier legs settle. Choose the guided wizard or full calculator. Future lay prices remain assumptions until matched.

How to use the Sequential Lay Calculator

  1. Choose the wizard or full calculator. Under Bet type, select Qualifying bet or the appropriate SR/SNR free-bet mode.
  2. Enter Back stake and total Back odds. Add legs in settlement order and enter each leg’s Lay odds and Lay commission %.
  3. Choose Standard, Let it run or Lock in final leg for a cash bet; free-bet modes use Equal profit. Review the planned stakes and outcome table.
  4. Only place the next required lay if the earlier bookmaker selections have won. Update actual placed stake, odds and commission instead of overwriting earlier exposure with a new estimate.
  5. Mark legs as placed, won or lost as appropriate. Recheck the next available price and stop the sequence when the accumulator loses.

Modes and outcomes

Qualifying includes the cash stake. SR returns the eligible promotional stake with winnings; SNR does not. Free-bet calculations use the equal-profit approach, while cash stakes offer different strategies for how later exposure is managed.

A planned later lay is conditional on earlier selections winning. The initial table assumes your entered prices remain available. Overlapping events or odds movements can prevent the planned sequence from being followed.

Standard balances each live leg against the value carried forward. Let it run aims to break even if a leg loses while leaving the all-win result variable. Lock in final leg follows that approach until the last leg, then balances the last two outcomes. Equal profit solves free-bet stakes across stopped and all-win outcomes.

Worked examples

Two-leg qualifying accumulator

Enter £10 cash at total bookmaker odds 4.00. Use two successive legs at bookmaker odds 2.00 and lay odds 2.00 each, zero commission, no boost and Standard strategy.

Lay £10 on leg one (liability £10). If the first bookmaker selection wins, lay £20 on leg two (liability £20). The calculated result is £0 if leg one loses, leg two loses or both win, provided both assumed prices are available.

Two-leg SNR accumulator

Keep total odds 4.00 and both 2.00 lay prices, but use a £10 SNR promotional stake with no boost and zero commission.

Lay £7.50 on leg one, then £15 on leg two only if the first selection wins. Liabilities are £7.50 and £15. Each modelled outcome produces £7.50 profit at those prices.

These examples use the stated inputs, not current market prices. Check settlement rules, matched amounts and available odds. Currency rounding can leave small differences between outcomes.

Adjustments and changing odds

Use actual placed stake, odds and commission to retain the exposure already taken. Custom lay stakes change the outcome balance. Apply a boost preset only when the bookmaker bet meets its conditions; the examples above use no boost. Neither view places exchange bets for you.

Frequently asked questions

Should I lay every leg immediately?

This tool models successive lays conditional on earlier selections winning. Laying all legs upfront creates a different position.

What happens after a selection loses?

The accumulator has lost, so later conditional lays are no longer needed for that sequence.

What if the next lay price changes?

Update that leg with the new price while retaining earlier placed bets. Review the revised outcomes before continuing.

Can I use it when events overlap?

The planned sequence may be impossible if a later market closes before an earlier leg settles. Check timing before starting.

Are the wizard and full calculator different methods?

They are two interfaces to the same sequential calculation. Choose the view that suits how you want to enter and review the legs.
