There’s no magic number of exactly how much you should have in savings by the time you are 25. Assuming you have started working by this age, a good rule of thumb is to put aside 10 % of your salary each month into savings. If you get a raise or a bonus, you can put aside that much more. A smart way to go about this is to make a list of everything you spend money on every month, including the 'must spends' like rent, groceries and fuel to the 'feel good' expenses like eating out and spending on clothes, and then decide how much can be saved. Ideally, the amount you need to save should be put away at the start of each month before other expenses are met.
