Those who find that debt problems have damaged their credit rating could find it may affect future job applications, claimed Equifax.
The credit checking service commented on the impact of credit history when applying for certain jobs, which could affect those looking to relieve debt issues.
External affairs director at Equifax Neil Munroe said: "If you’re going into a position where there’s finance involved, it would probably seem appropriate that the employer checks your credit history."
Mr Munroe added that it was important that students checked their credit record on leaving education, both in order to check for mistakes and to remedy bad credit as they enter employment.
A survey amongst NUS members by Equifax revealed that 22 per cent of students do not know how much they have spent each month until they get monthly statements from their bank or credit card company.
The research also showed that students leaving university in 2010 could expect to be carrying around £30,000 of debt.
