Get advice if you are having money problems. It can be hard to ask for help, but there are lots of organisations who will help. They won't judge you or make you feel bad. They are there to help you deal with your debt.
The Loan Calculator from the Money Advice Service can help you work out how long it will take you to pay off your loan, based on your current monthly payments. If you're having money problems, it's best to get some free, independent advice from a charity before you take on any further debt.
