“I save 10% of my salary — that’s more than enough.”

Write your awesome label here.
“I put 10% aside—it’s the golden rule.” Here’s how to respond to that overly generalized idea.

Saving 10%: a popular habit, but often insufficient

For a long time, the 10% rule has been repeated like a mantra in personal finance: set aside 10% of your salary and you’ll be secure. While it’s a good starting point, this universal rule doesn’t account for the real complexity of financial planning. The key question isn’t simply how much you save, but rather for what goals, over what period, and with what expected return.

A simple rule… that’s outdated

The origin of the 10% rule goes back to early 20th-century personal finance and self-help books such as *The Richest Man in Babylon*. It had the merit of instilling a saving discipline among workers at a time when government pensions and registered plans were less developed.

But today’s economic realities are very different: longer life expectancy, rising cost of living, complex taxation, higher housing prices, and uncertain market returns. For many people, 10% is simply not enough to achieve financial independence.

The right savings rate depends on your situation

A young person who starts saving at 22 and plans to work until 65 could realistically reach their goals with a 10% savings rate — especially if they invest wisely over the long term. But someone who starts saving seriously at 40 will likely need to aim for 20% or more to make up for lost time.

Another key factor is income. Someone earning $40,000 a year and saving 10% is setting aside $4,000 annually. But is that enough to fund 25 to 30 years of retirement — plus travel, home renovations, or unexpected health expenses? Without other assets, the answer is no.

Inflation, retirement, and longevity

One of the great silent enemies of saving is inflation. A retirement income of $40,000 today won’t have the same purchasing power in 25 years. It’s also important to consider that retirement periods are getting longer. It’s no longer uncommon to live to 90 or even 95 years old. This means that retirement can last as long as an entire professional career.

Current recommendations

Financial institutions and planners generally recommend saving between 15% and 20% of your annual income, including RRSP, TFSA, and any group plan contributions. This figure may seem high, but it reflects a more realistic approach to long-term planning. Moreover, by taking advantage of available tax-efficient tools, it’s often possible to lessen the net impact on your budget.

The real issue: planning according to your goals

It’s not about saying that 10% is bad — for many people, it’s already a significant effort. But we must stop believing it’s a guarantee of financial security. The best strategy is to have a personalized plan with clear goals, an assessment of future expenses, a defined time horizon, and an investment strategy tailored to your situation.

Conclusion

In summary: saving 10% is better than saving nothing. But believing that it’s enough in all circumstances can give you a false sense of security.
