Dear Liz: I am trying to raise my credit scores, which are very low. I have one negative mark on my account from a paid collection and I just got my first secured credit card. I have a bit of extra money right now and I’m wondering what’s the best way to use it to raise my scores. Should I get another secured credit card from a different issuer, get a secured 12-month loan through my financial institution or something else?

Answer: People rebuilding their credit often overlook the importance of an emergency fund. Having even a small amount of savings can keep a financial setback, such as a decrease in income or an unexpected expense, from causing you to miss a payment and undoing all your efforts to boost your scores. You can start with just a few hundred dollars and slowly build the fund over time.

Adding an installment loan can assist with building credit as well, but a secured loan may not be the best option if money is tight. The cash you deposit with the lender as collateral for the loan won’t be available again until you pay off the loan. Consider instead a credit-builder loan, in which the money you borrow is placed in a savings account or certificate of deposit to be claimed when you’ve finished making the monthly payments, typically after one year. That means you can keep the cash you already have for emergencies. Credit-builder loans are available from some credit unions and Self Lender, an online company.

You’ll want to make sure both the credit card issuer and the installment loan lender are reporting your payments to the three credit bureaus. If your accounts don’t show up on your credit reports, they’re not helping to build your scores.

In addition to making payments on time, you’ll want to avoid using too much of the available credit on the card. There’s no bright line for how much to charge, but typically 30% or less is good, 20% or less is better and 10% or less is best. Use the card lightly but regularly and pay it off in full every month because there’s no advantage to carrying a balance.
