What this tool calculates
This calculator grades one alternate spread and applies standard decimal-odds payout rules. It does not compare live alternate lines or source prices automatically.
Adjusted margin = selected team points + selected spread − opponent points. Positive is a win, zero is a push, and negative is a loss.
Results use the assumptions shown on this page. Actual settlement may differ under operator, jurisdiction, or market-specific rules.
Worked example
If the selected team wins 108–104 and the alternate spread is −3.5, the adjusted margin is +0.5, so the bet wins. A $100 stake at 1.91 returns $191 for $91 profit.

FAQ
How do I grade a basketball alternate spread?
Add the selected spread to your team’s final score and compare the adjusted score with the opponent.
Can an alternate spread push?
Yes, when a whole-number spread makes the adjusted scores equal and the operator uses standard push settlement.
Do alternate spreads use different payout math?
No. Once graded, the return uses the quoted odds; alternate lines simply have different handicaps and prices.
Does overtime count for basketball spread bets?
It commonly does, but the exact competition and operator rules control settlement.
Does this page find the best alternate spread odds?
No. It grades and prices the score, spread, stake, and decimal odds you enter.
