Hook: Your premium changed.Nothing else did.What gives? Welcome to the invisible force shaping how much you pay for personal insurance.

What it is.Why it exists.How it’s used.

Some states limit or prohibit its use, and carriers comply accordingly.Where allowed, it sits alongside other rating factors to help the insurer estimate expected loss.Why do insurers use it? Simple cause and effect.

Insurance pricing is probability math.Carriers study huge datasets to find signals that correlate with claims.Credit-based attributes have historically shown a strong correlation with frequency and severity of losses.

When a signal reliably predicts risk, it tends to be used to refine pricing.That refinement cuts both ways.It can lower premiums for many, hold them flat for some, and raise them for a smaller group whose profile statistically aligns with higher loss risk.
