The only free multi lay calculator with profit tracker integration
Calculate multiple lay stakes for bet builders, correct-score boosts, and other matched betting offers where one bookmaker bet can win through several mutually exclusive outcomes.
Use AiProfit's Multi Lay Calculator to lay each outcome separately, compare every possible settlement result, check the calculator's total liability, and save the full bet set into your free profit tracker. AiProfit is the only matched betting platform offering free profit tracker integration for this calculator.
Enter your bookmaker back stake, back odds, and bet type, then add each lay outcome that could make the bookmaker bet win. You can add outcomes manually or use presets for common bet-builder and correct-score scenarios. This is especially useful for laying bet builders, where one bookmaker selection may need several correct-score lays on the exchange.
For each lay row, enter the exchange lay odds and commission. AiProfit will calculate the lay stakes, row liabilities, total liability, and net outcomes across the full bet set.
Once the calculation looks right, save the multi lay bet into AiProfit's free matched betting profit tracker so your back bet, lay rows, calculated stakes, expected result, and tracker details stay together.
Multi lay betting is especially useful for bet builders because a single bookmaker bet can often win through more than one exact result.
For example, a bet builder such as Team A to win and under 2.5 goals may be covered by exact scores like 1-0 and 2-0. Both scores make the bookmaker bet win, but only one of them can happen in the match. That means you need to lay each possible winning score separately.
The Multi Lay Calculator helps you build that hedge in one place. Add the relevant outcomes, check the lay stakes, compare the settlement results, and save the final bet set to your profit tracker before the bet settles.
Presets make the calculator faster when you are laying common bet-builder or correct-score angles. Instead of manually adding every row from scratch, choose a preset that matches the structure of the bookmaker bet, then adjust the lay odds, commission, outcome labels, or outcome list as needed.
| Preset label in the calculator | Example bookmaker bet | Example lay outcomes |
|---|---|---|
| Home Win + Under 2.5 Goals | Home team to win and under 2.5 goals | 1-0, 2-0 |
| Home Win + Under 3.5 Goals | Home team to win and under 3.5 goals | 1-0, 2-0, 2-1, 3-0 |
| Draw + Under 2.5 Goals | Draw and under 2.5 goals | 0-0, 1-1 |
| Home Win to Nil + Under 3.5 Goals | Home team to win to nil and under 3.5 goals | 1-0, 2-0, 3-0 |
| Custom multi lay | Any mutually exclusive set | User-defined outcomes |
The calculator also includes the matching away-team versions where the same logic applies to the away side. Presets are there to reduce manual entry, not replace checking the market. Always confirm that the selected outcomes match the bookmaker bet and that the exchange markets have enough liquidity before placing the lays.
A multi lay calculator is a matched betting tool for hedging one bookmaker back bet that can win through several mutually exclusive outcomes. It calculates separate lay stakes for each outcome and compares the net result if the back bet loses or wins through any listed result.
Instead of laying one selection, you lay every covered outcome. This is useful for bet builders, correct-score boosts, and other offers where the bookmaker bet can win in more than one exact way.
For example, if your bookmaker bet wins on 1-0 or 2-0, you add both outcomes to the calculator. AiProfit then shows the lay stake for each score and the net result for each possible settlement.
Use this calculator when your bookmaker bet covers several outcomes, but only one of those outcomes can happen at settlement.
Use the standard matched betting calculator when there is only one lay outcome. Use the each way calculator for win/place hedging, the extra place calculator for extra-place racing offers, and the bet calculator hub for accumulator or system-bet return maths.
Imagine you back a football bet builder that wins if the home team wins and the match has under 2.5 goals. That bet builder is covered by these exact scores:
| Lay outcome | Why it is included |
|---|---|
| Home team wins 1-0 | The bookmaker bet wins |
| Home team wins 2-0 | The bookmaker bet wins |
Those scores are mutually exclusive. The match cannot finish both 1-0 and 2-0, but either score would make the bookmaker bet win.
| Settlement case | What happens |
|---|---|
| Back bet loses | Neither 1-0 nor 2-0 happens, so all listed lays win. |
| 1-0 happens | The bookmaker bet wins, the 1-0 lay loses, and the 2-0 lay wins. |
| 2-0 happens | The bookmaker bet wins, the 2-0 lay loses, and the 1-0 lay wins. |
This is why a normal matched betting calculator is not enough for this scenario. A standard calculator works well when there is one back outcome and one lay outcome. A multi lay calculator is needed when the same bookmaker bet can win through several exact results.
The Multi Lay Calculator starts with a grouped lay solution for all listed mutually exclusive outcomes. This is different from a normal one-back, one-lay hedge because the calculator has to compare the all-lays-win result against every possible back-win outcome.
With Custom lay switched off, the calculator uses standard multi lay sizing. It calculates the lay stakes as one grouped hedge across the full outcome set.
Switch on Custom lay to reveal the available grouped sizing controls and the Shared lay multiplier slider. Some controls are disabled when they match the standard result.
The slider applies one multiplier to every calculated lay stake. It changes the grouped lay stakes together; it does not edit one outcome's stake independently.
Underlaying and overlaying are general matched betting staking concepts. For the full explanation on a normal one-back, one-lay hedge, use the standard matched betting calculator.
Each lay row shows its own liability. The summary line in the calculator is labelled total liability, and for this tool it means the maximum effective liability for one realistic settlement result.
That total liability figure allows for the fact that the listed lay outcomes should be mutually exclusive. Only one listed lay outcome can lose, while the other listed lays would win.
It is not a raw sum of every row's liability. If you place lays across different exchanges, you should still make sure each exchange has enough balance for the lays being placed there.
Multi lay bets are harder to track than standard matched bets because every outcome has its own lay stake, liability, and settlement result. Save the full calculation into AiProfit's free profit tracker so you can compare the expected result with the actual profit or qualifying loss after settlement.
Most multi lay calculators stop after calculating the lay stakes. AiProfit goes further by letting users save the full multi lay bet set into the free profit tracker, keeping the calculation attached to matched betting records instead of a separate spreadsheet.

Use the Multi Lay Calculator when the bookmaker bet has several mutually exclusive winning outcomes. Use the standard matched betting calculator when there is only one lay outcome. Use the each-way and extra-place calculators for racing workflows, and use the bet calculator hub for accumulator or system-bet return maths.
Multi lay bets are more complex than normal back-and-lay hedges, so users should check the setup carefully before placing anything. If you still need close bookmaker and exchange odds before calculating, use the OddsMatcher first.
Make sure:
If you are new to exchange betting, read AiProfit's lay betting guide before placing a multi lay.
A multi lay calculator works out the lay stake, liability, and net result for each outcome in a multi-outcome matched bet. It is used when one bookmaker back bet can win through several mutually exclusive results.
Yes. Multi lay is especially useful for bet builders that can win through several exact scores. For example, a bet builder such as Team A to win and under 2.5 goals may need separate lays for 1-0 and 2-0.
Presets are prebuilt outcome groups for common multi lay scenarios, such as correct-score groups or bet builders that map to several exact scores. They help users add likely lay rows faster, but users should still check every outcome against the bookmaker bet.
For this calculator, the listed lay outcomes should be mutually exclusive. That means only one can happen at settlement. If two or more listed outcomes can happen together, this is not the right calculator.
Total liability is the calculator's label for the maximum effective liability across one realistic settlement result. It allows for the listed outcomes being mutually exclusive.
No. The row liabilities show the exposure for each individual lay. The total liability shown by this calculator is the biggest realistic exposure from a single settlement result when the listed outcomes are mutually exclusive.
No. The standard matched betting calculator is for one back bet and one lay bet, including standard lay, underlay and overlay staking. The Multi Lay Calculator is for one bookmaker bet that needs several lay bets because it can win through several mutually exclusive outcomes.
Yes. AiProfit lets you save the full multi lay bet set into the free profit tracker, including the back bet, lay rows, calculated stakes, and expected result.
Yes. AiProfit's profit tracker is free to use. Logged-in users can save bets, monitor expected and actual profit, and review matched betting activity without needing a separate spreadsheet.
Yes. AiProfit is the only matched betting platform offering free profit tracker integration for this calculator, so you can calculate a multi lay bet and save the full bet set in the same workflow.
Yes. The calculator supports qualifying bets and stake-not-returned free bets, shown in the calculator as Free bet - SNR. Choose the correct bet type before calculating.
Use the standard matched betting calculator for one-back, one-lay bets. Use the each-way calculator for win/place hedging. Use the extra-place calculator for extra-place racing offers. Use the bet calculator hub for accumulator and system-bet return maths.
