How you compare
Your A/TO ratio against NBA ball-handling standards
Reading the ratio
Assist-to-turnover ratio is the cleanest ball-security number in basketball: how many assists a player creates for every giveaway. League-wide, teams hover a little under 2 assists per turnover. For lead guards the bar is higher — 2.5 is solid, 3 is excellent, and the great ball-security seasons (peak Chris Paul, Tyus Jones, Muggsy Bogues) push past 4. Big men live lower because their touches come in traffic; judge a center at 1.5 very differently from a point guard at 1.5.
Fold it into a fuller picture with the player efficiency calculator, which prices turnovers at a full point each.
How it’s calculated
A/TO = assists ÷ turnovers. Zero turnovers with at least one assist shows as a perfect (infinite) ratio — enjoy it while it lasts. Enter games to get per-game rates alongside the ratio.
Position matters: guard standards run roughly a point higher than big-man standards at every tier.
Frequently asked questions
What is a good assist-to-turnover ratio?
NBA teams average a little under 2. For lead guards, 2.5+ is solid, 3+ is excellent, and 4+ is historic ball security. For forwards and centers, anything at 1.5+ is genuinely good because their touches come in heavier traffic.
Who has the best assist-to-turnover ratio in NBA history?
Among high-assist players, the gold standard is peak Chris Paul, who posted full seasons above 4 — and specialists like Tyus Jones have led the league above 5. Muggsy Bogues was the career pace-setter of the pre-analytics era.
Does a high A/TO always mean a good playmaker?
No — it measures security, not creation. A low-usage guard who only makes safe passes can post a gaudy ratio while creating little. Read it next to raw assists and usage: high volume AND a high ratio is what makes elite floor generals elite.
