First of all, you need to work out how much you actual have left after necessary spendings. To do this, write a list of everything that NEEDS to go out of your bank in that month. For example bills, food, phone, Netflix, gym memberships, fuel, insurance etc. Take this figure away from your monthly wage and make sure you don't touch it. Keep it in your account at all times so you can pay your bills!
STEP 2: INVEST
You should invest 10% of whats left per month. This could be simply putting in to your company pension scheme which I highly recommend. Or you may know be an expert in trading (cryptocurrency market is BOOMING in 2018). Just invest some money to help you in the future. STEP 3: START SAVING
Now decide how much you want to save a month. I would suggest about 10% of whats left if you have no specific aim but it really will help to have a target (e.g. if you want to aim for £1000 in your savings in a year, you would need to put away £84 a month). I am going to suggest that if you are aiming for a certain amount, that you actually aim a bit over that. Just so when you do hit that target, you're not taking ALL of your savings out of the account, you still have a bit there for unexpected costs. Put this money into a separate savings account. Some banks offer quite good interest rates so you will gain a bit of extra money just by keeping your money in an account with them so its good to look around! Try to avoid touching these funds at all costs.
STEP 4: WEEKLY BUDGET
The easiest way to budget is to break it down in to a weekly budget. Take the figure you have left to spend for the month and divide it by the number of weeks in that month. It's much easier to see what you have left to spend if you do it weekly. Really try and stick to this weekly budget! If you do need to go over your weekly budget (you might see something you really want to buy), make sure to recalculate how much you will have left for the month and then break it down weekly again. If you are going to be struggling to stick to the remaining budget each week then you need to decide whether its worth over spending that week!
STEP 5: TRY NOT OVERSPENDING
You don't need to spend your full weekly budget just because its there. Some weeks you may have plans and spend it all, but it feels good getting to the end of the week and having a bit left over of your weekly budget. You could spread that amount over the other weeks left in the month, or add a bit more to your savings.
There you have it! By the end of the year you should be living comfortably each week and have a nice amount of money in your savings to either spend on a holiday/car or just keep it going. If you have been a little more adventurous in your investments, hopefully you're seeing growth and are on track to making BIG money!
