Understanding Spread to Moneyline Conversion
Point spreads and moneylines are mathematically related but not perfectly correlated. This calculator uses historical data to estimate what moneyline odds correspond to a given spread.
Key numbers in football (3, 7, 10, 14) create non-linear relationships because so many games land on these margins. A -3 spread has a significantly different ML conversion than -3.5.
Use this tool to compare value between spread and moneyline bets. If a book's actual moneyline offers better odds than this calculator suggests, you may have found value.

Frequently Asked Questions
How do I convert a moneyline to a point spread?
There is no exact formula, but market-derived tables map moneylines to spreads. For NFL, roughly -150 equates to -3, -200 to -4.5, and -300 to -7. The mapping shifts by sport based on scoring distribution and key numbers.
What moneyline is equivalent to -3 in the NFL?
An NFL 3-point favorite is typically about -150 to -170 on the moneyline, because home teams win by exactly 3 more often than any other margin. Around key numbers the moneyline moves faster than the spread suggests.
Why do moneyline and spread prices sometimes disagree?
The market prices each independently, so temporary gaps appear - especially around key numbers like 3 and 7 in football. Comparing the derived moneyline from a spread against the actual posted moneyline is a common way to find value.
