How Much of Your Pre-Retirement Income Do You Really Need?

For years financial planners and fund companies have often recommended replacing roughly 60% to 80% of pre-retirement income to maintain your standard of living after you stop working. New analysis from human resource consultants Morneau Shepell, however, suggests the reality may be quite different for many Canadians. Their findings echo earlier research commissioned by Statistics Canada and reported by MoneySense, indicating that a typical retired household may need substantially less than conventional wisdom assumes.

What the Study Found

Morneau Shepell modeled a couple who were working before retirement and used typical midlife expenses to estimate how much income they would require afterward. In a scenario where the couple had combined employment income of $100,000, owned their home, and had raised two children, the study concluded they would only need to replace about 43% of their pre-retirement income in retirement. If the couple had been childless, the required replacement rate rose to roughly 55%.

These figures challenge the blanket 60%–80% rule and highlight how household circumstances—homeownership, family size and lifecycle stage—drive retirement spending needs. The take-away is that a one-size-fits-all percentage can be misleading; the right replacement rate depends on the costs you will and will not carry into retirement.

Why Retirement Spending Often Falls

There are a number of common, practical reasons retirees typically need less income than they earned while working:

Child-related expenses decline or disappear once children are grown and independent.
Mortgage payments often end before or during retirement, removing a major monthly commitment.
Work-related costs — commuting, professional wardrobes, meals away from home and other employment expenses — generally shrink or vanish.
Retirees no longer contribute to registered retirement plans or need to set aside money for long-term accumulation.
Income-tax obligations often fall, depending on income sources and levels in retirement.

“This helps explain why there isn’t a retirement crisis,” says Fred Vettese, chief actuary at Morneau Shepell. “Retirees are okay because they generally find, to their pleasant surprise, that they don’t need as much as they thought.” That perspective resonates with many households who discover actual retirement spending is lower than anticipated once the big midlife costs end.

What This Means for Your Planning

While the Morneau Shepell results are encouraging, they do not mean everyone can assume a low replacement ratio. Personal circumstances, health needs, lifestyle choices, geographic location and unexpected costs vary widely. Use the following steps to develop a realistic picture of your own retirement income needs:

Prepare a detailed budget of current expenses and identify which costs will end, reduce, or increase in retirement.
Account for new or rising expenses that can appear in retirement, such as increased healthcare, home maintenance or travel plans.
Factor in taxes on retirement income and the timing of government benefits and workplace pensions.
Consider longevity and the potential need for long-term care savings or insurance.
Review your portfolio and withdrawal strategy in the context of sustainable spending over an uncertain retirement horizon.

Estimating a replacement rate is a useful starting point, but the most reliable plans are rooted in your own expenses and goals. For many households, a replacement ratio well under the conventional 60%–80% range may be realistic, especially if mortgage and child-rearing costs have been completed before retirement. At the same time, others may need to plan for higher spending, particularly if they expect costly health needs or want a more affluent retirement lifestyle.

Final Thoughts

The lesson from recent research is that retirement planning works best when it is personalized. Broad rules of thumb can mislead or provide a false sense of security. Examine your specific circumstances, update estimates as life changes, and consider talking with a financial advisor to create a retirement income plan that reflects your priorities and risks. Accurate, individualized planning will give you the best chance of achieving a comfortable and secure retirement without over- or under-saving.
