Overlay and Underlay

The calculator includes modes for Underlay and Overlay which are two handy settings for advanced matched betting strategies.

Here we’ll explain what each one means and how you can use them.

Overlay

Using the Normal Bet option, the calculator works out a lay stake that leaves you level (nil profit or loss) if the selection loses but you will lose slightly more than normal if the selection wins.

When to use Overlay

Because you lose nothing if your selection wins, Overlaying is an option when placing qualifying bets on offers that give free bets for backing a winner, like bet365 Ch4 4/1 offer and Betfair free bet if your horse wins at SP 3/1+.

It means you can play the offer without loss, however, you will lose to the betting exchange when the selection wins and you must ensure your qualifying loss is low enough to leave a profit from the free bet.

In the example below, we’ve bet £50 at odds of 5.0 and overlaid £52.63 at 5.2 on the exchange. If the selection loses, we’ve lost nothing and if it wins we’ve lost £21.05 but will have a £50 free bet from which we’d expect to earn £40.

Underlay

Using the Normal Bet option, the calculator works out a lay stake that leaves you with nil profit or loss if the selection wins and slightly bigger than normal loss if the selection loses.

When to use Underlay

Underlaying is an option when placing qualifying bets on deposit bonuses with large wagering requirements. We always recommend you place the bet your bonus at higher odds in the hope the selection loses and you won’t have any furthering wagering. But, sometimes these selections will win and by underlaying you can save some of the cost of completing the full wagering.

In the example below, we’ve bet our £50 bonus at odds of 5.0 and underlaid £47.62 at 5.2 on the betting exchange. If the selection wins we haven’t lost anything so reducing the cost of the full wagering requirement which we now have to meet. If the selection loses, we’ll lose a little more that if we’d used the Normal mode but there will be no more wagering to complete and we keep a substantial amount of the bonus.
