What is a Lucky 15 Bet Calculator?
The Lucky 15 bet calculator we’ve just introduced is an essential tool for all bettors looking to place system bets. This type of wager involves entering four selections, combined into 15 bets distributed as follows:
| Bet Type | Number | Description |
| Singles | 4 | One bet for each of the 4 selections. |
| Doubles | 6 | All possible combinations of 2 selections. |
| Trebles | 4 | All possible combinations of 3 selections. |
| Fourfold | 1 | One combination including all 4 selections. |
How to Use a Lucky 15 Bet Calculator
Using the Lucky 15 calculator is simple and intuitive. The JavaScript application at the top of this page is already configured. Just enter the odds for four sports events (from any discipline), the stake you want to bet, and the type of odds (decimal, fractional, or American). In just a few moments, the system will automatically calculate your potential winnings and net profit.
A Practical Example
Let’s say you choose four events with the following odds: 2.80, 3.80, 2.90, and 1.90. If you bet €1 on each of the 15 combinations (total €15), the potential return could be €225.82, with a net profit of €210.82, assuming all outcomes are successful. If only three selections win, the system will still calculate a reduced, yet significant, payout.
