Congratulations you've just started your first job!
Whether you've just finished further education with a large student loan or come straight from school, you may be shocked at how little you have left from your first pay packet as you'll find new expenses which you didn't bargain for.
Now is the time to get into a good habit and build a budget of your take-home pay and compare it to your likely monthly spend. If you have a student loan then any monthly repayments will be taken out of your pay before you receive it, so you won't have to budget for this expense.
In time you will hopefully have a little spare cash left over each month so you could get into the savings habit early.
Or you might decide to treat yourself or make a purchase that you couldn't afford before you started working. If it's something big, like a car, you'll have to decide whether to save up and buy it when you have enough money or borrow the money, using a credit card or by taking out a personal loan.
Remember to use your credit cards and bank accounts wisely so that you start to build up a good credit rating, this might be vital in a few years time.
If your company is offering a pension plan, then it's never too early to join. The sooner you do so, the more time you will have to build up a pension.
