How to calculate your Qualifying Bet?

To calculate your qualifying bet with our matched betting calculator, you need to change it on NORMALYour Back Stake will be the value of the BACK BET, the bet you place at the bookmakerFor example, if you bet £25 on Betfred, then you would put ’25’ in the Back Stake box. Your Back Odds are the odds of the bet you placed from bookie; let’s say that you placed the £25 on Chelsea to win at 2.0 – Back Odds is 2.0. The Back Commission box will almost always be 0%, unless you are placing your bet on a betting exchange.  

The Lay Odds are the odds that you have laid your bet at any Exchange Market, such as Betfair, Smarkets, etc. Using the previous example, at Smarkets,  Chelsea had a lay odd of 2.15. So, you put 2.15 into the Lay Odds box. The Lay Commission is the commission from exchange market,  on Betfair is 5%, Smarkets is 2%, etc. So, the Lay Commission is than 2%.

If you put in the numbers listed above as an example, the calculator should show a loss of -£2.00 and your lay stake of £23.47.

How to calculate your Free Bet?

To calculate your profit from the free bet, you need to change the Bet Type from NORMAL to FREE BET SNR (Free Bet – Stake Not Returned). There will be very few occasions when you need to use Free Bet (SR), so for the moment you don’t need to worry about this option.  Using the same principle from “How to calculate your Qualifying Bet?” tab, just simply add your Back Stake, Back and Lay Odds, and Lay Commission and our free lay calculator will do the job for you. 

Remember to use your free bets at higher odds, we would recommend above 5. However, try to prevent using them on horse racing, so your risk to get gubbed is lowered

For this example, we backed Watford to win at odds of 5.0 at a £25 stake (free bet) and laid them on Exchange Market at odds of 5.2. With 2% commission included, the back lay calculator shows that you will make a profit of £18.92 from this match, regardless of who wins. Your NET PROFIT will be £16.92 = £18.92 – £2.00 (the lost on our qualifying bet).

Is possible to overlay and underlay?

Unfortunately, at this point, our lay matched betting free calculator, doesn’t allow the option of underlay or overlay for your selected events. However, with a more advanced matched betting calculator, such as OddsMonkey calculator or Profit Accumulator calculator you will be able to do this. 

If you aren’t familiar with what underlaying and overlaying means, please have a full read through our recommended guide – Underlaying and Overlaying in Matched Betting. However, in a short description, using the underlay or overlay option gives you the flexibility of increasing or decreasing your profit, respectively your loss depending on the outcome of your selected event.
