Hedging calculator

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 shows the arithmetic. It doesn't tell you whether the price fits your read of the outcome or your budget. Decide the stake before you enter it. Check the market rules. Keep essential money out of it entirely.

Cross-check on a second tool. The calculator hub, Dutching or Closing line value cover the same numbers from a different angle. Same price conventions, so a decimal price in one is a decimal price in the other.

Read the price format guide if you're new to the formats. Two minutes.

Reading a rounded result

Money is rounded to two decimals here. A real settlement applies its own rounding sequence, which can differ. Keep the original inputs written down if you're going to check the number later.

Unclear about an input? Find the stated market term. Don't guess. A quick sanity check: change one input by a small amount and see whether the result moves the way you expect.

That doesn't validate the market. It can flag a reversed sign, a mis-entered price format or a duplicated stake. Use the number to understand the arithmetic. It's not a reason to ignore a limit you set in advance.
