About this site
Smarter Trades - Free Betfair Trading Tools is a small collection of free calculators built for exchange bettors who want to take a more structured approach to staking, liability and bankroll management. The aim is to provide simple tools that run entirely in your browser so you can check the numbers before you commit to a trade.
Who runs Smarter Trades?
This site is run by an individual trader with an interest in betting exchange maths, risk management and strategy testing. It is not affiliated with Betfair or any other bookmaker or betting exchange. All opinions and examples on this site are personal and are not investment advice.
What the calculators are (and are not) for
The dutching, lay, hedge, EV and Kelly calculators are designed to help you understand:
- how much you are risking when you lay a selection;
- how your stake can be split across multiple outcomes;
- whether your estimated edge is positive or negative on a given price;
- how your bankroll might grow (or shrink) over time with different staking plans.
They are not tipster tools and do not tell you what to back or lay. The inputs come from your own analysis and judgement, and the tools simply turn those inputs into clearer numbers.
Responsible gambling
Betting and trading on sports always involves risk. You can lose money very quickly if you stake more than you can afford or misjudge probabilities. You should only bet with money you can afford to lose and you should take a break if gambling stops being enjoyable.
If you feel your gambling is becoming a problem, please seek help from a recognised support service such as BeGambleAware or your local equivalent.
