Parlay Calculator 15 Teams

A parlay bet is a type of sports wager where you combine multiple individual bets into a single wager. If all the individual bets win, you win the parlay. If any single bet loses, the entire parlay loses. This calculator helps you calculate the combined odds and potential payout for a 15-team parlay.

What is a Parlay Bet?

A parlay bet (also called an accumulator bet) is a single wager that combines multiple individual bets. For example, you might bet on 15 different sports events and win a large payout if all 15 outcomes are correct. The key characteristics of a parlay bet are:

Combines multiple individual bets into one
All selections must win for the parlay to win
Odds are calculated by multiplying the decimal odds of each selection
Payout is calculated based on the combined odds

Parlays are popular among sports bettors because they offer the potential for large payouts, but they also come with higher risk since a single losing bet can eliminate your entire wager.

How to Use This Calculator

To use the parlay calculator for 15 teams:

Enter the decimal odds for each of your 15 selections
Enter your total bet amount
Click "Calculate" to see your combined odds and potential payout
Review the results and adjust your bets as needed

Note: This calculator assumes you're using American odds. If you're using fractional or decimal odds, you may need to convert them first.

The Parlay Formula

The combined odds for a parlay are calculated by multiplying the decimal odds of each individual selection. The formula is:

Combined Odds = Odds₁ × Odds₂ × ... × Odds₁₅

The potential payout is calculated by multiplying your bet amount by the combined odds:

Potential Payout = Bet Amount × Combined Odds

For example, if you bet $100 on a 15-team parlay with combined odds of 150, your potential payout would be $15,000.

Worked Example

Let's look at a concrete example with 15 teams:

Team	Bet Type	Odds
Team A	Moneyline	+200
Team B	Spread	-150
Team C	Total Points	+120
Team D	Moneyline	+150
Team E	Spread	-120
Team F	Total Points	+180
Team G	Moneyline	+250
Team H	Spread	-180
Team I	Total Points	+200
Team J	Moneyline	+300
Team K	Spread	-200
Team L	Total Points	+250
Team M	Moneyline	+400
Team N	Spread	-250
Team O	Total Points	+300

First, we need to convert the American odds to decimal odds:

+200 becomes 3.00
-150 becomes 1.67
+120 becomes 2.20
+150 becomes 2.50
-120 becomes 1.83
+180 becomes 2.80
+250 becomes 3.50
-180 becomes 1.56
+200 becomes 3.00
+300 becomes 4.00
-200 becomes 1.50
+250 becomes 3.50
+400 becomes 5.00
-250 becomes 1.40
+300 becomes 4.00

Now we multiply all the decimal odds together:

Combined Odds = 3.00 × 1.67 × 2.20 × 2.50 × 1.83 × 2.80 × 3.50 × 1.56 × 3.00 × 4.00 × 1.50 × 3.50 × 5.00 × 1.40 × 4.00

Calculating this gives us a combined odds of approximately 1,250,000.00. If you bet $100 on this parlay, your potential payout would be $125,000.

Frequently Asked Questions

What is the maximum number of teams I can calculate with this tool?

This calculator is specifically designed for 15-team parlays. If you need to calculate a different number of teams, please use our general parlay calculator.

How do I convert American odds to decimal odds?

For positive American odds (e.g., +200), add 100 to the number and divide by 100 (200 + 100 = 300; 300 ÷ 100 = 3.00). For negative American odds (e.g., -150), divide 100 by the absolute value of the number (100 ÷ 150 ≈ 0.67; subtract from 1 to get 1.67).

What happens if one of my selections loses?

If any single selection in your parlay loses, the entire parlay loses, and you don't receive any payout. This is why parlays are considered higher-risk bets.

Can I use this calculator for other sports besides football?

Yes, this calculator can be used for any sport where parlay betting is available, including basketball, baseball, hockey, and more.
