Sequential Lay Calculator

Plan an accumulator hedge one leg at a time. Enter the stake, the combined back odds and each leg’s lay price to get every lay stake, liability and outcome before you place a bet, then update later prices as earlier legs settle. The calculator is free, with no sign-up needed.

Members can let the Acca Finder pick an acca from live bookmaker and exchange prices and open it in the calculator with every leg filled in. It needs a free AiProfit account; the calculator does not.

How to use the Sequential Lay Calculator

  1. Use the calculator above with your own selections. Members can also send an acca from the Acca Finder, which opens the calculator with every leg filled in. Under Bet type, choose Cash bet or the free-bet option that matches your promotion: stake returned or stake not returned.
  2. Enter the Back stake and the Combined back odds. Add legs in kick-off order and enter each leg’s Lay odds and Commission (%). If the bookmaker boosts accas, set the boost on the back bet so the all-win outcome includes it.
  3. For a cash bet choose Standard, Let it run or Lock in final leg; free bets use Equal profit. Open Outcomes and liability to see every lay stake, the largest stake you will need and what each outcome pays.
  4. Place the acca with your bookmaker and mark the back bet placed. Lay the first leg at the stake shown, mark it placed, then record whether that selection won or lost. Later legs stay locked until the earlier selections have won.
  5. Before each later lay, check the live price and update the leg if it has moved. Earlier lays keep their recorded stake, odds and commission. The sequence ends when a selection loses.

Bet types, strategies and outcomes

A cash bet includes your stake in the return. A stake-returned free bet pays the stake back with the winnings; a stake-not-returned free bet pays the winnings only. Free bets 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 only when the bookmaker bet meets its conditions; the examples above use no boost. Neither the calculator nor the Acca Finder places 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.

What does the Acca Finder do that the calculator does not?

It searches current bookmaker and exchange prices for an acca that fits your legs, stake, kick-off window and limits, then ranks the options by the result you lock in at today’s prices. Using one saves a plan to your Profit Tracker and opens it in this calculator with every leg filled in. It needs an AiProfit account; the calculator does not.

Do I need an account?

Not for the calculator. Saving a plan to your Profit Tracker, and the Acca Finder itself, need a free AiProfit account.
