When considering how much you’ll need to retire, the phrase ‘how long is a piece of string’ springs to mind. The answer depends on what the money’s going to be used for and how long it needs to last you. The exact amount you’ll need to live comfortably will depend on your expectations and circumstances, and how much you’re willing to compromise. It’s estimated that you’ll need around 70% of your final salary to maintain your lifestyle once you retire.
