Free calculator

Use the matched betting calculator before you place anything.

Matched Betting Trading includes a free calculator for qualifying bets, free bets, lay stake planning, liability, and exchange commission. It is designed to help you see the numbers before you touch a live bookmaker or exchange page.

Matched betting calculator

Enter the bookmaker odds, exchange odds, and commission to estimate the lay stake, liability, and both outcomes before you place anything.

This mode is for the first cash bet used to unlock an offer or free bet.

Calculation result

Use this as a planning view only. Small rounding differences and live price movement can change the final pence.

Ready for a result

Choose the right mode, enter the current odds, and run the calculation to see the lay stake, liability, and both outcomes.

Why this tool helps

The calculator is here to make the numbers more legible, not to skip the learning process around terms, exchanges, and disciplined record-keeping.

Check the lay stake before you place anything

The calculator gives you a clean lay-stake estimate so you can see the plan before moving onto a live bookmaker or exchange page.

See liability and both outcomes

You can view the exchange liability and the estimated outcome if the selection wins or loses instead of guessing from odds alone.

Use it with the starter pack and guides

The calculator works best alongside the starter pack, the offer-terms guide, and the exchange explainer rather than as a standalone shortcut.

Checks before you trust a result

  • Use the latest live odds from the bookmaker and exchange rather than stale screenshots.
  • Check whether the free bet is stake not returned or stake returned before choosing a mode.
  • Make sure the exchange commission percentage matches the exchange you are using.
  • Round real-world stakes to the precision the bookmaker and exchange actually allow.

Where to go next

  • Get the starter pack

    Use the pack if you want the offer checks, exchange basics, and first-session workflow alongside the calculator.

  • Read the offer-terms guide

    Use this before applying the calculator to a real offer so the headline does not hide the awkward clauses.

  • Read the exchange guide

    If liability, commission, or unmatched bets still feel unclear, the exchange guide is the right next step.

  • Open the Outplayed review

    If you want calculators, tutorials, and software support in one platform, start with the Outplayed review next.

This calculator is educational and planning-focused. It helps with stake and liability estimates, but it does not replace live odds, current operator terms, exchange commission checks, or safer-play judgement.
