Not everyone needs to save for retirement.

This is of interest to Canadian Boomers, but there is also information that might be of interest to those in the United States, Britain, Australia and New Zealand. Some Canadians will have enough income to fund their postwork lives without ever setting aside a dime in their own savings accounts. How do you know whether you’re one of them?

The answer hinges on how much you’ll get automatically from the retirement income sources you build up by living and working in Canada

A target to aim for: The Organization for Economic Co-operation and Development (OECD) tracks retirement income data across its 34 member countries – and has established a “target replacement rate” for retirement income.

According to the OECD, retirees should aim to have 60 per cent of their gross pre-retirement income once they hang up their lunch buckets or turn in their office keys in order to maintain their standard of living as they age.

Across the OECD, the average gross replacement rate for the worker earning an average income is about 54 percent.

In Canada, retirees can typically expect to receive guaranteed lifetime income from Old Age Security (OAS), the Guaranteed Income Supplement (GIS) and the Canada Pension Plan (CPP), in addition to any other workplace pension income they might also receive.

A focus on retirement income, not retirement savings

Looking at Canada, the United States, Britain, Australia and New Zealand – collectively known as the Anglo-Saxon economies – retirees earning the average income can expect to receive between about one-third (in Britain) to one-half (in Australia) of their working income from guaranteed pensions once they hit retirement.

The OECD calculated these percentages by adding up the income from government and mandatory private pensions (such as CPP in Canada) and comparing it with earnings in member countries.

What if you aren’t earning the average income, but something less – or more? Here’s where the numbers get interesting: If you earn a lot more than the average income before retirement, you can expect to get a lot less, in percentage terms, of guaranteed lifetime pensions in retirement.

If you earn half of the average income, you might have 80 percent or more of your working income replaced in retirement from the mandatory public and private sources that you can’t outlive.

On the other side of the ledger, however, the replacement rate from guaranteed sources drops off significantly: Retirees earning one-and-a-half times the average income might need to replace roughly 75 percent or more of their preretirement income to hit the recommended target.

So many of us are saving enough, here are some interesting stats from CBC News. They have compiled a number of important figures on retirement and financial planning in Canada. All figures are from Statistics Canada unless otherwise indicated.
