Utilization threshold
A supposed cutoff, like 30%, where utilization starts hurting a score; scoring companies publish no official thresholds.
The 30% rule is everywhere, but FICO has said its data doesn't show a cliff at 30%. FICO's guidance is that lower is generally better, that staying below 10% tends to help, and that 0% can keep a file from earning the maximum. VantageScore suggests keeping utilization under 30%. Neither company publishes exact breakpoints, so any precise threshold you read about is an estimate.
Treat thresholds as rough guides and look at both measures: overall utilization and each card's own ratio. A low overall number doesn't cancel out one card near its limit. Before an application, the practical target is a small reported balance and low ratios everywhere, timed by paying before statement closing dates.
Example
Say your total limits are $12,000. To get under 30%, total reported balances must be below $3,600. To get under 10%, they must be below $1,200.
