We deal with the second major uncertainty in retirement: how much you’ll earn on your super and savings/investments.
Retirement Principle #3: The more you earn on your investments, the longer your savings will last and the more you can spend.
Sounds pretty obvious…but it might surprise you to know the difference it can make.
Here’s a way to see the impact. This chart shows the sustainable spending rate for various levels of investment return for a 67 year old couple with $500,000 in super and savings, planning on a retirement horizon till age 92. If they put their money under the mattress and earn nothing, they might be able to spend $61,700 per year. However if they were to earn 7% per year through a sensibly invested super fund, they might expect to spend $68,300 per year.
