Check Your Credit Report Once a Year — Errors Are Surprisingly Common

Credit bureaus handle billions of data points, and mistakes happen more often than you would expect. Studies have found that roughly one in five credit reports contains a material error — wrong accounts, incorrect balances, or debts that do not belong to you. These errors can silently lower your score and cost you thousands in higher interest rates.

Pulling your own report is free in most countries and takes about fifteen minutes. Review each account, verify the balances, and dispute anything that looks wrong. It is one of the highest-return habits in personal finance: a small investment of time that can protect you from paying for someone else's mistake.
