Back stake Back decimal odds Lay decimal odds Commission %

Example result

A 10.00 back bet at 3.00 and lay price 2.50 uses a 12.00 lay stake.

What this calculator answers

Balance a back position against a lay position. Enter the original back stake and both decimal prices to see a lay stake and the outcome figures before any charges.

Formula and worked example

Formula: Lay stake = back stake multiplied by back odds divided by lay odds. Liability = lay stake multiplied by lay odds minus 1.

A 10.00 back stake at 3.00 hedged at lay odds of 2.50 needs a 12.00 lay stake. The lay liability is 18.00 and both outcome figures are 2.00 before charges.

Checks before using the result

• Confusing lay stake with the liability needed to cover it.
• Ignoring charges or commission on a lay win.
• Using a price that has changed since the calculation.

When the calculation does not apply

It is an arithmetic comparison, not a settlement estimate. Charges, market suspension, partial matching and void rules can change the realised outcome.

Keep the number in context

A calculator makes the arithmetic visible, but it does not decide whether a price fits your budget or information. Write down the stake before placing anything, check the market rules, and keep essential money separate. The result is a planning figure, not a prediction of what will happen.

For another view, visit the calculator hub, compare the Dutching and Closing line value, or read the price format guide. These tools use the same price conventions, so you can check a number from more than one angle.

Reading a rounded result

Displayed money amounts are rounded to two decimal places, while a real settlement can apply its own rounding sequence. Keep the original inputs beside the result if you need to repeat the calculation later.

If an input is unclear, pause and find the stated market term rather than guessing. A useful check is to change one input by a small amount and see whether the result moves in the direction you expect.

That does not validate the market, but it can reveal a reversed sign, an incorrect price format or a duplicated stake. Use the final figure as an aid to understanding the arithmetic, not as a reason to ignore a limit you set in advance.
