How Couples Can Confidently Invest for Retirement Together

Investing for retirement as a couple often feels overwhelming. Different incomes, mismatched risk appetites, and the complexity of financial tools can make it hard to align on a plan.

However, as Emily Luk, CPA, CFA, and founder of the investment app Plenty, shared in our interview, it doesn't have to be that way.

Why Couples Struggle to Invest Effectively

One common issue Emily highlighted is a lack of collaboration. Research shows that one in four married couples miss out on employer retirement matches because they fail to coordinate contributions effectively​. This mistake alone can cost couples hundreds of thousands of dollars in lost compound growth over their careers.

Another hurdle is that most financial tools aren't designed for couples. Budgeting apps often track daily expenses but rarely address long-term goals like retirement​. For many, this leads to fragmented money management, with scattered accounts and overlooked opportunities.

Key Insights from Emily Luk

Focus on Goals, Not Just Expenses

Emily emphasized that couples should start conversations about their shared goals, whether it's retiring early, funding children's education, or buying a dream home. Starting with shared aspirations reduces tension and makes financial planning feel more purposeful​.

Understand the Basics of Investing

Emily debunked the myth that you need deep financial expertise to invest. A simple index fund strategy can outperform complex, high-fee portfolios over time. The key is consistency and a long-term mindset​.

Recognize the Power of Time in the Market

Using the Rule of 72, an initial $50,000 investment could grow to $400,000 in 30 years without adding another penny, assuming an 8% annual return​. The lesson? Start early and let compound interest work its magic.

Don't Overlook Taxes

Taxes can erode investment returns, and understanding tax-advantaged accounts (like Roth IRAs or employer 401(k)s) is critical. Emily highlighted how strategic tax planning can significantly boost after-tax returns​.

Actionable Steps for Couples to Invest Together

Emily offered simple, actionable advice for couples ready to take control of their financial future:

Take Inventory of Your Finances

Write down all your accounts—retirement plans, savings, brokerage accounts, and even forgotten 401(k)s from previous jobs. Most couples are surprised by how much they already have once they see it together​.

Start with Employer Matches

Ensure both partners contribute enough to their employer retirement plans to get the full match. It's free money that compounds over time​.

Automate Investments

Set up automatic contributions to retirement accounts and index funds. Automation eliminates the temptation to spend and ensures consistency.

Communicate Regularly

Schedule regular "money dates" to review progress, celebrate wins, and adjust plans as life changes. Financial transparency fosters trust and confidence​.

Explore Investment Platforms for Couples

Apps like Plenty are designed specifically to simplify investing for couples. They allow them to set goals, track progress, and collaboratively invest while balancing shared and individual finances​.

Final Takeaway

Investing for retirement doesn't have to be complicated or stressful. As Emily said, "You can get started without needing to know a ton about finance and investing in probably under three minutes."

Start small, stay consistent, and communicate openly. The earlier you begin, the more time your money has to grow—and the brighter your financial future together will be.
