Matched Betting Calculators

Every calculator on this site, what it’s for, and the guide that teaches the method behind it. All five are free, need no sign-up, and are the same tools our Discord bot opens pre-filled from live alerts.

Match Betting Calculator

The default tool, one back bet, one lay bet. Enter your stake and both sets of odds; it returns the exact lay stake, liability and profit. Three modes:

• Standard - equal profit both ways; the right mode for qualifying bets
• Underlay - profit concentrated on the back side; the right mode for boosts (why underlay wins)
• Overlay - profit on the lay side, for the rare cases that call for it

Plus a free bet (SNR) toggle for converting free bets.

Multi-Lay Calculator

For laying multiple outcomes of the same event, a builder or boost covering several correct scores. Sizes every lay so profit is balanced across all results, with per-outcome commission and Smarkets shared liability support. Method: the multi-laying guide.

Early Payout Calculator

The 2Up tool. Checks each opportunity with an automatic 2Up Rating based on implied odds, so you know before placing whether the qualifying cost is worth it, and its Advanced mode computes the lock-in lay or cash-out once your team goes two goals up.

Sequential Lay Calculator

For laying accas leg by leg in time order, each leg only after the previous one wins. Standard, Lock In (bank guaranteed profit mid-acca) and Freeze (Skybet Acca Freeze) modes. Method: the sequential laying guide.

Bet Builder Lock In Calculator

The advanced-2Up tool for bet builders on early payout offers: set up the scoreline lays pre-match, then use the in-play tab to lock in profit the moment your team goes two up. Method: bet builder early payout.
