Some money management tools such as Mint offer a way to check your credit score for free, on demand. This is very closely connected to your finances and is a reflection of how well you pay any outstanding bills, credit cards, loans and more.
By improving your credit score, you will increase your chances of being approved for financial products such as loans and mortgages and be able to access the lowest rates possible.
Repaying your bills, loans and debts on time is the most effective way to boost your credit score. You can also look at closing any credit cards or accounts that you do not use and avoid making too many loan applications in a short space of time.
