To answer your 'what figure' question, we think we will survive on approx. $55000 pa. There is only one way to find out! There are only two times,
NOW and TOO LATE.
I am basing my figures on information like this;

To help guide you to your number, financial firms have devised income and actuarial models that come up with a target multiple of your final year’s salary. Benefits consultant Aon Hewitt says that by age 65 an average full-career worker needs to have banked 11 times annual pay. That means a household earning $75,000 a year would need to have saved $825,000. Work to age 67 and the multiple drops to 9.4 ($705,000); retire at age 62 and the multiple rises to 13.5 ($1 million).
The fund company T. Rowe Price advises a multiple of 12 times final pay, while Fidelity calculates that a multiple of eight times pay will do the trick. All the firms use slightly different assumptions. But you can see that they are in the same ballpark and, more importantly, that it’s a big park.
Looking at it another way, BTN Research estimates that, assuming 5% average annual investment returns, for every $1,000 of monthly income you want over a 30-year retirement, you need $269,000 in the bank. Let’s consider that same household making $75,000 a year. To replace the commonly recommended 80% of income in retirement — or $60,000 in this case — the household would need $5,000 a month. In this calculation, this household’s number is $1.35 million, or 18 times final pay. A higher investment return would bring the numbers down.
Finally, there is the approach that Dallas Salisbury, president of the Employee Benefit Research Institute offers: You need 33 times what you expect to spend in your first year of retirement—after subtracting Social Security benefits. Let’s take that same household, which spends every penny of its $60,000 income in retirement. Say this household collects $20,000 a year in Social Security. That leaves it spending $40,000 from other sources. So this household still needs a nest egg of $1.32 million, or just shy of 18 times final pay.
Don’t be discouraged. These are just estimates. A household with two good traditional pensions plus Social Security, and zero savings, might be in fine shape while a household with $1 million in the bank and no guaranteed lifetime income ends up struggling. That’s why your spending–not your savings–may be the most important part of the equation.
Basing your number on final pay has another flaw. What if you are frugal and live on far less than you earn? The household that earns $75,000 a year but saves 20% and thus spends only $60,000 need not squirrel away as much as a household earning $60,000 a year but which through credit spends $75,000. The latter household, by the way, is headed for real trouble — and, sadly, this situation is not uncommon.
