How much should you have saved by 40?

Financial experts often use retirement savings benchmarks to determine whether someone is on track. A common guideline is to have two to three times your salary saved by age 40. That means if you earn $50,000 per year, a $100,000 401(k) balance is on the low end of the target. But if your salary is closer to $80,000 or $100,000, you may need to ramp up your savings.

Of course, these are just general guidelines. The real question is whether current savings habits will lead to a comfortable retirement down the road.

Will $100,000 grow enough by retirement?

You need to make an educated forecast of how much $100,000 will grow by retirement if it’s left untouched. The answer depends on investment returns. Historically, the stock market has averaged around 10% annually, but a more conservative estimate of 7% is often used for long-term planning.

Here’s how $100,000 could grow by age 65:

• At 10% growth: ~$1.08 million
• At 7% growth: ~$542,000

While these numbers look promising, most people will need more than this to retire comfortably — especially if they plan to rely on savings for 20 to 30 years. That’s why continuing to contribute to your 401(k) or IRA is crucial to building a solid retirement fund.

How much should you be saving?

If the goal is to retire comfortably, financial planners often recommend saving 15% to 20% of annual income, including employer contributions.

For example, if someone age 40 with $100,000 in their 401(k) earns $70,000 per year and contributes 10% of their salary while receiving a 4% employer match, their 401(k) savings would look something like this:

• By 50: ~$330,000
• By 60: ~$790,000
• By 65: ~$1.1 million-plus

This assumes a 7% annual return and steady contributions. Increasing the savings rate — even by just a few percentage points — could significantly boost retirement funds.

Other factors to consider

1. Lifestyle and retirement goals

How much someone needs in retirement depends on lifestyle expectations. A person planning to travel frequently or retire early will need more savings than someone who plans to live modestly in a low-cost area.

2. Other retirement accounts

A 401(k) isn’t the only option for retirement savings. If someone also has an IRA, taxable investment accounts, or rental income, their overall retirement picture could be much stronger.

3. Social security benefits

Social Security can supplement retirement savings, but it’s unlikely to cover all expenses. The average monthly benefit in 2024 is about $1,900, but actual benefits depend on lifetime earnings.

4. Debt and expenses

Entering retirement debt free can make a big difference. Paying off a mortgage, credit cards, and other loans before retiring can reduce the amount needed from savings.

Steps to get on track

If $100,000 at age 40 isn’t quite where someone wants to be, there are ways to catch up:

• Increase contributions: Boosting 401(k) contributions by 1% to 2% per year can add up significantly over time.
• Max out employer match: Not taking full advantage of an employer match is leaving free money on the table.
• Open an IRA: A Roth IRA or traditional IRA can provide additional tax advantages and investment flexibility.
• Consider brokerage accounts: Taxable investments can supplement retirement savings without the withdrawal restrictions of a 401(k).
• Delay retirement if needed: Working a few extra years can allow more time for savings to grow while increasing Social Security benefits.

Evaluate where you stand

A $100,000 401(k) at age 40 is a solid foundation, but whether it’s enough depends on future savings and retirement goals. By increasing contributions, minimizing debt, and taking advantage of investment growth, there’s still plenty of time to build a comfortable retirement.
