It depends on the lifestyle you want and how long your retirement needs to last. As a guide, the ASFA Retirement Standard estimates a single person needs around $630,000 in super for a “comfortable” retirement, and a couple around $730,000, assuming you own your home outright. Your own number will depend on your desired income, your age at retirement and how long you’re likely to need your savings to last, which is exactly what our calculator estimates for your situation.
