The Short Answer: A Small Dip, Then a Potential Climb
A personal loan affects your credit score in two distinct phases. Initially, you can expect a small, temporary drop of around 5 to 10 points. This happens because applying for the loan triggers a `hard inquiry` on your credit report. Lenders see this as you seeking new credit, which is a minor risk factor.
However, the long-term effect can be very positive. By making consistent, on-time payments each month, you build a positive payment history, which is the single most important factor in your `FICO Score`. Over the life of the loan, this responsible behavior can significantly support score improvement context, often leaving it much higher than before you borrowed.
For someone with a lower credit score, a personal loan can be a powerful tool for rebuilding credit. It demonstrates to future lenders that you can manage an installment loan responsibly. The key is how you manage the debt after you get it. The initial small drop is temporary, but the positive impact of on-time payments can last for years.
