Bonus True Position (BTP) is a key metric in sports betting that helps bettors understand the true value of a bet by accounting for the bookmaker's bonus offer. This calculator helps you calculate BTP quickly and accurately.
What is Bonus True Position?
Bonus True Position measures the actual value of a sports bet after accounting for the bookmaker's bonus offer. It helps bettors determine whether a bet is truly profitable by comparing the implied probability of the bet to the actual odds offered.
BTP is particularly useful when evaluating bets that include free bets or bonus offers, as these can significantly impact the true value of the wager.
BTP Formula
The formula for calculating Bonus True Position is:
BTP = (1 / Odds) - (1 / (Odds + Bonus))
Where:
- Odds - The decimal odds offered by the bookmaker
- Bonus - The amount of the bonus offer (e.g., 100 for a £100 free bet)
A positive BTP indicates a profitable bet, while a negative BTP indicates a losing bet.
How to Calculate BTP
To calculate BTP manually, follow these steps:
- Convert the fractional or American odds to decimal odds if necessary.
- Divide 1 by the decimal odds to get the implied probability.
- Add the bonus amount to the decimal odds.
- Divide 1 by the sum from step 3.
- Subtract the result from step 4 from the result from step 2.
For example, if you have a bet with decimal odds of 2.50 and a £100 bonus, the calculation would be:
BTP = (1 / 2.50) - (1 / (2.50 + 100)) = 0.40 - 0.0099 = 0.3901 or 39.01%
BTP Examples
Here are some examples of how BTP can be calculated for different scenarios:
| Decimal Odds | Bonus Amount | BTP | Interpretation |
|---|---|---|---|
| 2.00 | £50 | 0.3500 (35.00%) | Profitable bet |
| 3.50 | £100 | 0.2286 (22.86%) | Profitable bet |
| 1.50 | £200 | -0.1333 (-13.33%) | Unprofitable bet |
Bonus True Position FAQ
- What is the difference between True Position and Bonus True Position?
- True Position measures the value of a bet without considering any bonuses, while Bonus True Position accounts for the impact of bonus offers on the bet's value.
- How accurate is the BTP calculator?
- The calculator uses the standard BTP formula and provides accurate results based on the inputs you provide. However, always verify the results with your bookmaker's terms and conditions.
- Can BTP be used for all types of bets?
- BTP is most useful for bets that include bonus offers or free bets. For standard bets without bonuses, True Position may be more appropriate.
- What does a negative BTP mean?
- A negative BTP indicates that the bet is not profitable after accounting for the bonus offer. In such cases, the bettor may want to consider alternative betting strategies.
- How do I convert American odds to decimal odds for BTP calculation?
- To convert American odds to decimal odds, use the formula: Decimal Odds = (American Odds / 100) + 1 if the odds are positive, or Decimal Odds = (100 / |American Odds|) + 1 if the odds are negative.
